Deep Arctic - Divestream 02 - Hydrothermal FieldsAdded:
Welcome back on board Greeny's deep Arctic expedition. We're right now floating around in the ocean between Greenland and Norway. And underneath us, a few thousand meters down, the tectonic plates between North America and Europe are meeting, creating a mountain ridge with hydrothermal vent fields and underwater mountains with which creates biodiversity hotspots and animal life that you see nowhere else on the planet.
This is a mineral-rich area that the Norwegian government wanted to open up for deep sea mining, but that was stopped at least for the coming four years. And while they want to extract minerals here, we want to protect this area. So, we're here to document it together with with scientists. I'm going to go in and meet one of them in here in our wet lab and tell you a little bit about a dive we did yesterday over here by the samples. As you can see, the scientists are working hard with the samples from the ROV here. And one of the samples you can see here, this pink little piece of coral, it's actually called bamboo coral. And we don't quite know what exactly what species it is yet, but I'm going to hope we can see a closeup in here. In here behind me, Svin is working. He's our Blackwater photographer.
>> Hi, Svin.
>> Hi, Daniel.
>> I want to have a look at some of your pictures.
>> Sure.
>> We had basalt rocks and all the animals living on them. And we have here a kryinoid.
And um we also have the a sea spider and sponges. Of course, there a lot of research going on with sponges.
and uh the famous bamboo coral. Here you can see the polip.
>> So this is from our previous dive that was happening on a what we believe is a bamboo coral garden is creating like these 3D structure stretching over 800 meters over one of the mountain ridges.
Uh the scientists believe that this creates home for other animals and we found lots of eggs there which indicates that this might be a nursery for Arctic skates. So these ray species living out here. H. But the next dive is going to be something totally different. We're going down to 2,8 2,800 meters at a site no one ever dived before. So, we don't really know what to find, but it's going to be exciting for sure. You don't want to miss this. Let's go live.
Today at the beginning of the day anyway is Sergy and An Helena again.
And as you see, we're still on the descent.
We are approximately 150 m above the seafloor. So we do have some time to descent still.
All that beautiful light you see in the water is not from the sun, but from the wonderful light that we're bringing down on the ROV to see what's happening down here.
We're going to an area we have never ever visited before. And when I say we, I mean we as humans, nobody have been here before. We are a little bit northeast of an area called Favna which is an active venting uh field. So we will look at some mounds and some hills and some other interesting bimetry.
>> Mhm. So, we have just been able to look in the in the bthometric maps and decided an area that looked interesting and we are looking forward to exploring this together with you guys.
Yeah, we're going to be um something around 2,800 m which is almost three times the depth that we uh surveyed the previous uh streaming. She was like something around thousand meters depth. Uh some cases 900 meters depth uh in this bamboo coral reef, right?
>> Bamboo coral garden.
>> Garden. Yeah, >> bamboo coral garden.
>> Not yet a reef, but uh >> who knows?
>> Um so yeah, we're expecting quite different communities. uh but uh yeah it's uh not going to be until we reach to the bottom that we will be certain about the about this.
>> So right now we're sort of just waiting and this is a little bit later in the day than our last live scent dive. So this morning both Sergey and I have actually had time to have breakfast.
That was lovely.
>> What did you have?
>> Um, toast and some fruit.
>> Some fruit and I went for oatmeal. So, we're all good and ready to go for a long time in the shakare with you.
>> Also, there is a >> octopus.
>> Octopus. Double octopus, I think. Could it be >> dancing by? Yes.
>> I hope everybody got that one.
>> It's a bit elusive.
>> It was little bit away from us. Mhm.
>> And we're going down pretty fast to reach our >> uh bottom at 2,800 and a little bit maybe. And we are now already at 2,74.
>> Can you see the bottom now?
>> Can you see it now?
>> No.
>> Is that No, not yet. as just I think plankton that is passing by us.
It's almost like sitting in a spaceship and flying through the stars.
>> We are 20 m away from the bottom.
>> 20 m away from the bottom according to >> So this right?
>> No, this is a thing on the lens here.
>> Can't wait to see what's in there.
And uh yeah, we're going to be climbing, right? Uh a little bit. So, it's going to be like a ascent.
>> We normally want to do a little bit of an ascent. It's easier for the pilots to >> to see when we're going uphill than when we're going downhill.
>> Now we see the seafloor. Wow, look at that >> landing. And here we see I would say I hope none of my geologist friends are >> being angry with me but I think we are seeing some sort of oldish pillow lava.
>> Shall we go?
>> Yes. Look at the Well, check it out. You are there is an octopus.
>> Yeah, >> there is an octopus >> hanging out and looking at us.
>> Let's see if we can zoom in on it before we zoom in on the seafloor.
>> Wow. Wow. Wow. Wow. Wow. Look at that.
>> There is a lot of things in the water as well.
>> It's not as close as we would expect.
A beautiful uh forage of the this super beautiful creature.
>> And it's swimming away from us.
>> Yeah.
too light mean too bright for for this guy to be in here. Okay, coming back to what we are also interested in which is like uh describing life uh mainly this penic these organisms that live at the very bottom that they live attached to the very bottom and also some of them that are flying away. So, as you can see, there's a a really strong current, right? If you see the particles just flying away to the right, uh you will notice and you'll have an an estimation of of how um strong the currents are in here.
>> Well, that's for sure.
Anna, >> yes.
>> Not recording yet.
>> I am ready to start recording. If you are ready as well.
>> Oh, yeah. We want to do that as well.
Maybe we should start with doing Yeah, let's record and then we do white balance.
>> Okay. Can I?
>> Yes.
>> Start recording.
So, we've started the recording and um then the next thing we should try to do is to fix the white balance so that we have a good color uh level for you guys.
>> Oops.
This is the dust.
It's going to be washed away in a in a second. you'll see now, >> but it's quite a sedimentary um bottom we're landing on. And it's interesting because it's sediment in between all of these pillow lava, I think it looks like, >> or old pillow lava.
So, >> so there is a little bit of administration right here at the beginning of a dive to get everything ready.
>> Can you give me the coordinates? 85 >> 45 >> 93 or 98 >> 93 >> 95 22 >> 33 already >> 52 >> 52 >> 177 >> 177 >> 46 >> 46 I'm de >> 2768 27 >> 68 >> 68.
>> So >> yeah, >> almost two,800 m >> right now.
>> Yeah, >> that's a good place to hang. I think >> and checking that there is a big difference here.
>> And our pilots are trying to find out where it is a good place to hang. I think this is again a quite wild landscape we're having here. Look at that.
So, when our pilots find a comfortable place to either hang or settle down, we can fix the white balance and then we are ready to rock and roll, I guess.
What do you think, guys? Do you want to just hang here to do the white balance?
>> Yeah.
Obviously level here, so Sorry.
>> Can you >> potentially in the meantime? Right.
>> Just have a look at some of the creatures that we see in front of us.
Is this another sponge? You think >> I think >> but it is one of the unshaped ones. Oh, sorry. It's time for white balance.
>> Yes, we're ready for white balance.
Okay.
And I think we are seeing is that also enrusting sponges there on the side.
>> Yeah, we may have a look.
>> Yeah, afterwards.
>> Different sizes.
>> Yeah, >> different colors. But still sponges dominate this area.
>> Oh, this is a rocky deep sea area.
And we are getting ready to set the white balance of the video so that things do not appear too green or too yellow or something like that.
And for this we bring um a tool. It's not only used for this but also used for this to have um a known white surface that we can calibrate against.
>> Take this out.
You've come up. Yeah, it's quite tight.
>> And look, there is the fish.
>> Yeah, you kind of like >> he's swimming with his head down and his tail up.
>> Well, that's a beautiful way of swimming.
Hopefully we'll uh get some other um fish like this um during the transit so that we can just spend a bit more on the beauties.
>> Yes. Because today's transect is all about looking and exploring and we are not doing any >> strict mapping like we did on the previous >> bring it toward >> live. So shall I stay here?
>> Yeah. So you just uh zoom in a bit. Try and get more white on the screen.
>> Yeah.
>> Zoom in.
>> You tell me when you're ready. No.
Yay. Zoom in.
>> We are zooming in on the white to make sure that we get as much Oops.
>> Yeah. Oops.
>> No, there's something wrong. Seems like >> there is good.
>> It goes all the way down.
>> Yeah.
Right. Yeah.
And >> our zoom is a little bit um finicky this morning.
But we will see if we can fix that.
so that we can make you the most um smooth and beautiful video we can.
Let's check out.
>> Let's just take those away to make better workplace for you.
>> That's all you do.
I'm always impressed with how it's possible to repair something that is so far away from us from this box.
This is um long distance fixing channel four years like that for now.
then we came back. It says for two or 3 minutes and then again we try again for some seconds and drop.
Just in case there is any short, >> it stays in one, right?
>> Yeah, it just presets to that. Yeah. So, this one I might have to power this one off just now. Maybe it's cuz this one's powered up as well.
Um, should be a little box or >> Yep. Uh, you want to >> I'm just feeding with Yeah. Should be a door running somewhere in here.
>> We can turn on this light. Everything will be a lot easier.
>> Just need to find this one. Turn it off.
Yeah.
And then I think it connects when it's powered up as well.
So, we are still just trying to fix the um zoom on the camera so that we can >> smooth smoothly zoom in on all of the beautiful animals that we are going to see hopefully.
And while we're doing that, we're seeing a beautiful red jellyfish just passing by, floating by.
400.
Once this powers back up, it might do it like you can do it on the uh software here as well, but seem to be picking up.
>> Do we need to push something on this side?
>> No, it's okay. Yeah, >> should be sounds too.
>> So maybe I should put this light down here.
I'll try powering this one back one against this first one.
>> This here? Yeah. Yep. There.
Definitely Well, this is there's a lot of things happening in the shack right here. Now, we're still trying to get the camera to respond to the zoom.
>> Yes. Yeah.
Yeah.
So this is not responding. It's responding.
>> But the zoom is not responding.
>> So we are trying to fix. So this is the arm moving and not the zoom moving. We are trying to fix the zoom >> because of course we want to be able to zoom in on >> all of just seeing if it's beautiful animals >> and then after three or four minutes. I guess the only thing we can do is just have a look around.
>> Yeah, I was wondering if what we are seeing there on top of the left hand >> left >> clump is a sea star >> in addition to all of the >> at the very top >> sponges. Yes, because since we have so many sponges, it would be nice to see a sea star as well.
It's only zoom yet.
So J29 what's the line that we are doing here?
I can tell you that we're hanging out in in addition to being at um >> 2,767 m depth, it's also relatively cold.
It is -0 almost 7 0.68 Celsius down here.
And this of course is possible because the water has salt in it. So it does not freeze at zero. It freezes at approximately minus 1.7.
>> So we're one degree away from freezing point.
>> Just rotate a wee bit clockwise. Yep.
That way.
>> We're trying to set >> clockwise a bit more.
>> White balance without zoom.
>> Rotate clock. Yeah. Bit more. Bit more.
Rotate a bit more. Yep. Still better.
>> Just see if we can at least get that going.
But it seems right now that our camera box is not really responding. So, we are trying to fix that.
Yeah, maybe fixed.
Um, so it means that we cannot do like detailed shots. We cannot take detail shots of the specimens that we're going to be uh watching during this trans. But yes, we're still able to move the camera up and down and to the side.
Yeah, but we're not able to zoom right now. But that will come hopefully.
And because we have such a great gang of pilots with us, they know how to fix things that are >> something >> almost 3,000 m deep. Oh, look at that.
It's still like uh responding, right? Or >> still sticking.
>> You can do it on the software here, but it's uh it's not going to be as nice zooming on the software cuz you have to use the mouse as opposed to the the box. But I think the box is a maybe like a back the connection here is maybe dirty or something.
>> Um he said he's not on focus right now, right? So he's going to >> Yeah, shoot.
>> Yes, there's autofocus on it.
>> That's good.
>> And will it respond to the uh white balance trigger? Uh well, yeah, but it's not uh quite set up yet. I don't think mouse is gone though.
What's the mouse going on?
>> So, while we're having this beautiful view of our white balance measurements, white balance circle.
>> The white balance circle. Uh maybe I can ask some of you other guys who are not helping fixing the zoom. Uh why do we have the metal plate in the back? Is that for scraping off things when we're sampling?
>> What do you mean anything?
>> Um the the metal plate that is in the back, is that for some reason or is it to make it stronger? That's just so it stands up straight.
>> It's round and it would tip over. So, this is a balancing thing.
There is a lot of engineering that is on an ROV that we never think about as non ROV people.
Of course, it's important for the hand to be able to get to the the manipulator to get to that holding place on on the round >> um plate here. This >> camera potentially have an idea of where the arm is sitting. Yes.
>> Yes. This phone camera manager.
>> Do you want light?
>> No, it's okay.
box here. Yeah, there's a USB extender somewhere keyboard.
It's locked.
>> What you don't see from your possible view of of the shack is how this entire area is just filled with computer screens that are hanging on the wall in three heights. And how many? One, two, three, four, five, six.
to the side. So, we have 18 computer screens here. No, 16 computer screens here. And all of them are doing different things for us. So, um we're trying to connect um a computer mouse to the right screen, which is 16 possibilities.
So there is a lot a lot a lot of electronics to find out the right paths to here.
I think someone's maybe put the laptop down.
>> Oh, >> it's uh disturb the >> Should we move some of this back in there? I'll have a look at the other side now.
The space is also utilized to its utmost down here. So there is not a lot of space to move around things.
>> Yeah.
>> Making it more difficult to find the right port.
Is it hanging?
>> No.
>> Yeah. So, it's just getting stuck in there.
Yeah.
>> Forward then forward. If >> you are able to do the white balance or >> let's try to do the white balance. We zoom in all the way.
>> Yeah.
>> Well, when we let go, it still zooms in all the way.
And let's see. So, we are on the channel two and we just press right.
Okay, >> that looks good. That looks like a better white balance. Not so orange.
>> And then we can see what happens if we try to zoom out again.
>> No response.
>> No response.
>> I think we were able to do the white balance. So >> yeah, we've done the white balance, but now we only see a white field.
>> No, it's cuz >> Oh, there it goes back. This is a very either responding or not responding uh Zoom at the moment.
>> Yeah. Um box just um >> put this on here again.
>> Yeah, let's go just now. Carry on. Just know if you want. Let's let's go and um have a general look at this area without doing too much zooming but maybe a little bit >> I don't want to freeze it >> pointing back and forth >> in the right position.
>> Okay.
>> And we have made a plan for this dive as we talked about to go over a couple of small hills to see as far as you can because >> how they differ on different sides of the hills and >> okay >> what the hills are.
>> We think they look fun on the bimmetry.
So we want to have a look and see if it's um interesting in real life and not only on the pimemetry. Do you want to have this back maybe? Sure.
We take this here.
Here is your notes as I'm getting ready with this. So, here is your pen. Take your pick.
>> This one.
>> Yeah.
So sorry for that delay, but that's how it is to work with a large machine that is almost 3 kilometers below us here in the middle of the Norwegian Sea at um how far north are we? 72 and 12° north.
>> 72.
>> Yeah. So we are quite far north.
midnight sun.
>> Well, right now it's not midnight, but it was midnight sun this night.
>> And so this it's always light up above the water and it's always dark at these depths where we are now.
And we will start exploring how this quite dramatic landscape is looking.
And again, I think we're seeing some pillow lava that have been sedimented. So this is not very fresh um volcanic area but an area that has had some time to >> get slightly sedimented.
>> Maybe.
>> Yeah.
And as we talked about, but not really when you pass through uh zoomed into are a couple of >> sponges. A fan shaped sponge. Was it >> a fan shaped sponge? Yeah, >> fan shaped sponge and some encrusting sponges on the left side and the fan shaped sponge on the >> clump of of rock that is to the right.
Right.
>> Yeah.
>> Yeah. And there is some accepting Ellis I think on the on the rock back to on the left right now.
>> And I see on the very left >> we happy to go >> on the very left um shrimp.
Let's start a transact.
And from now on, we move along in our >> unexplored area.
And you can see there is a lot of moving things in this water. So that's not only sediment but also planktonic and slightly swimming small animals in that water. And let's now see if we can find more fish or maybe even another octopus.
>> Right now I think we're seeing small crustaceations and maybe some um Yeah, >> maybe some uh marine snow or all of that sediment >> coming in very very small packages falling down to the seafloor come.
>> So the plan is to move slowly along and have around.
>> Mhm.
It's going to be up this mountain >> like a bumbly walk.
>> Yeah, you can see them.
>> The rock formations here are crazy.
>> Yeah, there are this fun shape. I remember we collected one of those uh one of the previous times. the one with um brownish at the very center and then the edges being >> white or paling a little bit.
>> So, we're still um trying to position the ROB in a way that we see what's going on because we're going to be moving uh upwards in this uh mountain.
Again, nothing to worry about about these sedimentary plumes because they're going to be washed away um thanks to the currents, you know, in a while. This is a result of the ROB um >> lifting up >> lifting and after fly.
>> Yeah, I'm sure you know that. I also think about a little bit of swimming, but we're flying >> underwater flying.
>> We have no reference on here.
>> Yeah, >> we have no reference on that at the moment if you're on the line or not.
>> Guys, can you reply to again?
>> Yeah.
Yeah. Can you They've just called us out, please.
>> Do you want to answer them?
>> The dry lab. He wants the dry calling us.
>> He wants to have the because we are now trying to put the RV in the right configuration. If you could talk with the driver, >> we need to wait a little bit.
>> Yes, we will wait with the fisheye and then we after we have positioned the RV, we can play with other cameras again.
>> Yes, thank you.
So as always in the beginning of the dive there will be a lot of administration also for the pilots >> and um at the same time we're trying to fix this zoom thing.
>> I don't know.
>> Yeah just the zoom is >> zoom sticking again. Okay. Your power cycle is here.
>> There's fine now.
>> Still coming in like stick. So I tried to >> see this here though.
>> So you got to take that out.
>> Connect that to that.
That's what it's >> Yeah. Do you want to go on that now or what?
>> It's going to be a bit of difficult.
Yeah, >> I'll hang around for a while.
>> I will switch.
>> Switch your wall just in case cuz I was stuck in that way.
>> We're doing another attempt to repair the zoom.
>> That can be the label is there. Most people which I think has included waking up the bus too early.
Um just start.
>> So what we can see is that as we talked about there are patches of of very fine sediment in between this old volcanic rock area.
And there are some sponges sitting on on the different rocks that are sticking out of the very fine sediment.
>> And of course, what we don't see are all those animals that are living inside that extremely fine sediment.
>> Um, why am I saying that? I think this is extremely fine. It is because of the color and because of how those clouds form when we are landing and taking off. They're really, really finely sedimented clouds.
So, our pilots are trying to line up the ROV in the direction of our planned dive.
We will try to go approximately northeast.
>> Yeah.
So, we're lining up for that and then in parallel.
>> Wow. That is a very beautiful tenur.
>> Um swimming in front of us there. Um, we're also trying to fix the zoom so that we can give you a more um interesting experience along our uh drive. We also fly we also want to of course see what we are flying over.
But Sergy, do you think this is again a sponge?
>> That one that we already collected in a wonderful hour.
>> Uhhuh. I'm going to ask you to see whether he's any idea.
>> Yeah.
>> Julio is sitting in the lab and following us and will take over in some time when when we have a shift change here. But first we are going to >> work a little bit with you. Ooh. Now if you look at that sedimentary field, you see all those little holes or pockm marks. They are for sure where animals are living.
>> Either worms or clums or somebody lollipop sponges >> or maybe the lollipop sponges are attached down there. Do you think they can retract? that can also be >> um >> how about this oriented um the anemone that can pull down into their own tube like >> they also will like to sit in those and they will hide when we get close and they get stressed >> you got a keyboard >> yeah it's nice >> and if They remember from the keyboard sticking.
>> What's back there?
>> If I remember my understanding of sponges, this box would be uida.
>> Yeah, I think so. Exactly.
But uh not the same species that we saw.
>> No, it looks different. It's a lot more brown on the outside. Is that because it has been um taking in all of this slightly sedimented water maybe?
>> Okay, give it a second.
>> Yeah.
>> And we see that big >> opening that where the water will come out >> at the top there. But as Sergi said, these are glass sponges. So just to remind you, they are the animals that are made of glass.
>> So they are fragile but very beautiful. So all of their specules. All of their specules or some of their specules.
>> Yeah, they have. Yeah, >> all of the specules are made of glass.
Yeah, those of courseonges of sponges they call they're called carcarian sponges. And of course in this case there's no um this um the same kind of similar kind of a skeleton.
You're about to fix it.
>> Yeah.
>> Hopefully >> that will be wonderful.
And what do you think those small white dots are?
>> Not too sure.
>> But maybe they are also small white round sponges.
>> Yeah, >> small white dot.
>> We call them the small white round sponges for now and then when we have the zoom back we can >> examine them better.
Oops.
So, I think we're coming to a quite steep uphill of this sediment and rocks. So, we're back into that very dramatic landscape.
very steep. You see?
>> Yeah.
>> And you can notice one just for a moment.
That's why I couldn't get >> And we're having those little round white sponges. Maybe 30.
>> Mhm. Yeah.
>> We collected one in the previous time.
for the source.
>> Oo, look. It's almost like those rocks, those >> volcanic rocks are just hanging in the sediment here. That looks crazy.
>> Okay, we would like to 045 0.1 knots continuous.
So the shrimp super like to seems that they like to sit in this >> seedings >> very steep sediment >> with these outcrops of of rock.
>> Fish about where they're swimming. They're mainly floating with the water. They can do a little bit of control, but not super much.
So, when they seem to come crashing into us, it's mainly because they're make maybe just hanging there and we are >> slightly crashing into them.
Yeah, I don't want some customs. some sponges >> and some anemone. Anemone. Yay.
We should start recording some of these again now. So, and is that the pink thing is also interesting sponge?
>> Oh, yeah. The white thing is just below sponge.
Probably not the same species we've seen so far in our previous eyes.
Thank you, Paddy.
>> Is it fixed now?
>> Yeah. Thank you so much.
>> Thank you. Thank you.
>> Yeah.
>> So, good to go.
>> Out of his sleeping time came Patty to fix everything with the um zoom for us.
And hopefully from now we will have a an interesting dive. And um when we are getting a little bit more control now we can again look at all of those.
>> I'm pretty sure those are >> lollipop sponges. You see >> just try to you can see from the shadow like this.
Just have a look.
Those holes.
>> Yeah, the holes. I don't know.
They were some lollipop sponges. Yeah.
>> Yeah, there are some lollipop sponges here. And yesterday we decided we would call them dila.
>> Dordilla. Yeah.
And um then I think some of those other holes are um >> Yeah, I see.
>> Maybe worms or maybe >> something else. I think that is a worm sticking out actually.
>> Yeah.
>> Okay. So, let's just >> maybe a seabellid worm or something like that. They like to stick out here again on the left hand side up right hand side. And then you see this is an crusting sponge >> and an anemone on the side of that rock below.
Now we are talking about where we are looking first when when we are >> rich are we >> our where where is our focus when we are looking if you are a sponge expert you will of course always look first at the sponges >> can we increase >> the most organisms >> this is ah yeah this is a hexaclet that we didn't see the other day and those things this spaghetti >> the spaghetti This is white spaghetti like stuff.
Those are sponges too. And these are really common species called >> we >> Yeah, we will never forget this name.
>> I am trying to learn Latin names of sponges here. So, it's very good to sit together with Seri because he knows them already and can help us learning them.
>> And then I have a cheat sheet in front of me as well so I can at least say some names that are standing there.
and we are flying. I think maybe if you are um when it's good for you, we might be able to take out that um other camera that um >> the sexton. Yes.
>> Okay.
>> When it works for you.
You see this is another fun shaped sponge right there. Yes.
>> It's a bit difficult right now because it's super steep. Oh, no. It's not a punch shaped sponge.
>> Looks like one of those balls coming out.
I can take those until we have something to note.
>> Yeah.
>> And then you have a little bit better space.
>> Yeah. Thank you so much.
>> It's really um a little bit like Tetris to find the space for all of the things we need to have here.
So >> today there's been quite a lot of >> you see >> technicalities in the beginning but I think now >> is fully.
>> Thank you so much.
>> This thing that just appeared at the very bottom uh of the image on the left hand side is a special camera. This >> 180 something like that.
>> Yeah. You might already see the film from it. If if the guys up in the production are playing, >> but we are looking at the animals on the back there. I think there is another big white anemone.
>> Yeah. And the thing you can see now um with orang-ish color is another sponge.
It's a um unshaped sponge leorics. So we will be talking about um the position of different things that appear in the video. Um sometimes referring to the two lasers that you see in the on the very center of the image.
So I guess you you see them >> and we should say that there is 10 cm or 100 mm between those two >> dots >> at the very bottom. These lasers are going out in parallel to each other from the ROV so that we know always what is 10 cm >> lollipop.
>> Okay. We have >> on the right hand side.
>> Yeah.
>> Okay.
connected.
>> There's a few sponges here.
>> Difficult to make to make a guess on the species.
Uh the only species that we are well one of the ones is this one that appears just to the right of the lasers. You can see them at the very bottom of this rock. Those are lisoendorics complicata.
And since we're talking so much about this Lizard Dorics Complica, >> I think it is one of the favorites of Sergey, right?
>> Yeah.
>> At least right now, it's one of the favorites.
>> Yeah, I would say the the most uh interesting for our purposes.
>> We can talk about our purposes, right?
>> Why don't you talk a little bit about the Lizard and Dorics?
>> So, spaghetti sponge I call it.
So, one of the um objectives, scientific objectives of this uh cruise is collecting organisms that occur in different areas uh on the different areas of we're going to be surveying and also that they occur at different uh depth different bimetrical ranges. So it's this is super important to I mean for us since we want to identify which are the connectivity patterns in between the different areas that we're going to be surveying and also at different medical depths. German.
>> So is one of your theories that it might be different species if they are deep or >> not really >> shallow or if it's just different populations that do not have a lot of contact.
>> Yeah. Yeah. Yeah. That's that's one of the things that we want to test whether they are different species or not. They look alike. Um, we've been collecting samples from up to 2,000 m and up to 900 m with the same potential, the new species. And if they happen to be the same species, we're going to be testing um connectivity, but also we're going to be uh trying to identify patterns of adaptation. So you can imagine that the um conditions at um around 1 th000 m depth the pressure conditions are going to be uh a bit quite different from the ones that we are getting in here like uh almost three times um the depth that we've been surveying yesterday for >> so you want to see if they are then um genetically slightly different because of this. Yeah.
>> And I think I learned the other day you told us that the Lisodendorics, Kikata and other Lisaendorics do not have uh ooh another of those beautiful red jellyfish.
>> Beautiful.
>> Uh I love them. They are so peaceful.
>> You can see now. And remember, jellyfish are in the same group of animals as anemone and corals. They are all in the nidaria >> and they are named so because they have stinging cells. There's a fish.
>> Yeah, indeed.
>> This head.
>> And I think these are >> 20. I think these are sabelle or are they >> either sabellits or the lollipop fish >> lollipop sponge. Sorry.
>> But that was a fish.
>> So we were talking about that lisodorics that it does not have larvi that are floating in the water. They are brooders. So they >> make their babies and it's still a sexual reproduction.
So there needs to be a mommy sponge and a daddy sponge.
>> Yeah.
>> But they are hemaphrodites.
>> So they can help each other.
>> Yeah.
>> To one can be they can do sperm over to each other's eggs >> anyway.
>> Yeah.
>> But we need to have two sponges close to each other and then they will breed the babies inside their sponge.
>> Yeah. So we were uh taking some pictures yesterday from some of the specimens that we collected and we happened to find some of these embryos uh in the tissue of lendorics complicated. It means that u at least a few some of the individuals in this um population were actively u I mean they're like uh in the right time to be reproducing >> and would you call it pregnant if it is a sponge?
>> Yeah. Yeah. So, we found pregnant sponges.
>> That's cool.
>> Another fish coming up here.
>> But just to finish up with that Lizardic story. One of the things that this implicates is that Oh, they are sabalids. Those uh worms that are sticking up around it.
>> Look at that. That's beautiful. One of the things when you have a brooding animal that is not having a freel stage is that they don't spread so much. And this is why I think you want to look at the genetic connection between different populations because how can we find out how much contact these different populations have right >> yeah that's a very interesting question to look at >> so this makes leorics complicate a a very good candidate um to study this connectivity patterns I mean the adults do not move >> and the embryos >> babies don't move that much the embryos are going to be producing. They're going to become uh larve and these larvi are going to be released into the water column and uh there's not going to be much time until they need to find the right spot. It means that they cannot uh travel let's say uh that much. So they have a limited dispersal ability >> and this under a genetic population genetics uh point of view is uh this is one of the things that you me as a um marine ecologist uh doing genetics doing connectivity is one of the best candidates to be studied.
>> Could we zoom in a little bit on the sellets?
>> Yeah, sure.
>> We are going to play with the zoom since we have it again.
So, what we see are worms that live in tubes down into this very soft sediment and then they come out of their tubes with their tentacles and sit there and search for food and they must be just picking up little >> organic matter.
>> Organic matter that comes down through the water column and land on them. that they are um predators as we will talk about later with some of the species that hopefully will also be in the video. But yeah, these organisms there seem to be I don't know. We have to have a closer look.
>> Yeah, >> could feel like stuff.
>> Could be too too small, I think. Yeah, >> if there is one, it has this ah >> I was getting the >> head and then tentacles coming out of the head.
>> Sometimes ah those are >> aren't they like they are Nigerians. So definitely we're going to need to uh samples uh sample sample this these guys so that we can identify. Yeah, maybe they are uh do you think that they are not worms but that they are it's so far to it's difficult to see but stocked cranoids maybe >> could be I mean there's a a bunch of um organisms that they have gotten to the to similar evolutionary um um solutions for getting the estab of the >> energy coming down through the water.
Huh?
>> Make a stalk so that you get a little bit up from the seafloor and have your feeding area a few centimeters above the seafloor.
Is that the general strategy?
>> Yeah. for some of these of these different fila which are group big groups of organisms that um have evolved independently uh but they have in some cases reach to a similar solution in terms of um um getting the food uh from the water.
Yeah. From the water column.
Yeah, there's a bunch of them.
Maybe there are several different things but they look quite similar all of them.
at least from this distance. But that was of course always a problem.
>> There's a shrimp at the very back image.
>> Yeah. On left right of the image.
>> And shrimp like to stand on the bottom and just hang out and look at after food.
>> Even though they are very good swimmers.
So quite a different habitat if you compare uh this with our previous dives.
And >> yeah, if you were with us last time we were diving that was very different.
>> It was also steep like this has been at some times now.
We are going um over a a very soft sediment here and um as we said I think there are a lot of life right below the surface here. So um I would definitely not call this dead at all. I think this is just hiding a little bit from us.
Uh but there are several animals that live right on the surface. They are normally quite tiny.
>> And uh I have been spending the last 5 hours of this this first 5 hours of this morning's shift sitting and looking at tiny little animals in the microscope that we sampled with our last uh with our last uh dive.
And the average size was 2 to 3 mm.
And when we see how small 10 cm is here, we can understand how it's impossible to see some of those 2 to 3 mm animals.
>> Jellyfish is >> the jellyfish come in all different types of red and dark brown. And >> yeah, >> that's really cool.
I wonder if they're what is making them look so different in color. If it's just where how they hit our light or >> if it is what they have been eating or >> Mhm.
>> I have no idea.
>> Reach.
>> Can we come to the 0.2 knot speed?
Okay, thanks.
Okay, some rocks, which uh means that there's going to be cesile organisms. You know that there's also cesile organisms in >> there are definitely some of the podulla by the way.
>> Yeah, you see that one?
Oh, I think it's a potential.
>> Is that another Lisa and Dorics?
>> Yeah, a listen.
>> So, there is a reason we have been talking about this the entire morning so far.
>> They are very common in this area.
>> Yeah, indeed. Now, uh, now we are at 2, >> 750 m.
>> Yeah. And at some point, uh, we're going to be sampling and trying to get u samples from this area. So it's really important that we um sample I mean for our purpose uh otherwise we cannot identify species otherwise we cannot identify this connectivity that we just were just talking about uh some time ago and it means that in some cases we're getting whole specimen and most of the cases we're going to try to avoid this is just taking a piece uh of these specimens so that we can bring them up and we study them under the um microscope or steroscope and then we preserve this material um for different purposes and one of the purposes is to not only of listenoric sampling but of all of the sampling that we are doing is to build what we call um a genetic sequence library and that is because we want to make an overview of we want to understand and make an overview of what species are actually living in this area. We can go to literature and we can find out what has been found before so we can have an idea. As I said in the beginning of this dive, nobody has been exactly here before ever of humans. Um, but even in the entire Norwegian Sea, there hasn't been that much sampling in the deep. The deep sea is very little studied because it's so far away from us. It's so difficult to to work in the deep end. And it's just the last 10 15 years we have been able to go down with our extended eyes the ROVs and look.
So we have some samples but not very many from most deep sea areas that have been sampled at all. We don't have very many samples and trying to find out which species are living here and trying to get a library of what their genetic buildup looks like will help us to later use less invasive techniques like environmental DNA.
>> So there's a rock. Yes, I have a rock.
You see that?
>> Yeah. But >> just taking a water sample or a sediment sample or an active filter sample and say what is the DNA here and how many different species without being able to compare with a library of what those sequences connect to which species. We will only be able to say oh there is 25 or there is 58.
>> Yeah. But we don't know what those 25 or 58 are. If they are species or if they are populations or if they are we don't without that library we don't know anything more than there are some differing genetic coding around here. So it's for the purposes of making these less invasive methods available to use. we do need to first build these libraries.
So that is why you will see us sampling lots of different things to build up these libraries and make it possible to compare our environmental DNA with these lists of this genetic string belongs to that species type of libraries. Yeah, indeed. Yeah.
>> And this is a thing we have been doing at very many museums around in the world the last 10 15 years now. Um building libraries of the nearby local uh fauna and flora.
Um ooh >> yeah, plenty of crusting sponges.
>> As soon as we get some hard surface.
>> One fish there all standing.
>> Oh, again we have this um beautiful uh exactly it's probably um roselli and then some crust encrusting sponges. So the different white uh or yellowish stuff that you see there, those are sponges.
And the one that has all the pink little dots in the end there is that again the lizard and dorics.
>> That one here. Yeah.
>> That was again the lizard and >> I think there were also some cranialas.
Some of the >> brain sponges.
>> Yeah. Guys that always turn here and appear in these communities.
>> So this is again a steeper uphill.
So, we are starting on >> we're going to be able to >> a mound >> and this was one of the things that we wanted to >> to look at.
>> Yeah.
>> Let's just wait a little bit because in this area >> when we planned this dive >> rocks, >> we we looked at these for us to find >> little hills in this seafloor and decided that they could be an interesting thing to >> Okay. Right. them to >> dive over. So, >> now we're going starting to go up the hill of one of these >> small mounds or relative small mounts that we found.
>> Look at that. When you zoom in, there's plenty of life. You can see >> Yeah, look at that.
>> Plenty of life in the sea bottom.
>> Definitely. It looks like little stars hanging out there.
>> I think those those are kryoids. You see? You think they're kryoids? Yeah, that might be >> stalk uh kryinoids.
>> And maybe we have a kryinoid field and not um a worm field. I like kryoids a lot.
>> Yeah, for that I we need to stop at some point and collect samples.
>> And I think we have kryoids here. They they are non-stopped kryoids hanging out on the um >> on the rocks. And these are definitely volcanic rock. Yeah, >> you can see how the lava at some point in time has just poured out and gotten cold from meeting with the cold sea water >> again. The sea le you can see in the image top left.
Oh, now it's going to be >> ah they're great.
>> Yeah, you see >> there's plenty of them.
And these are animals that are sitting and picking up little organisms from the water.
So all the time it seems to be a heavily heavily sedimented area where we just see some of that volcanic rock sticking out every now and then.
Um, and I must remind you all that this is a quite steep uphill that we are doing, which would probably make that sediment a little bit unstable. It's always the possibility of rolling down, but we have loads of what we now think.
If we could just have a closeup look maybe strenuids.
>> Yeah, I think so.
>> Kinoids are part of the um ainoderms and they are close to sea stars. So if this is if thisides we would have a field of close related animals to sea stars standing on stalks in the sediments.
>> You see this one?
>> But it's quite hard to see. Maybe some of you who are watching can have the possibility of zooming back or stopping the video and looking at it again which we don't have here at all. We're just sitting and watching it live which I guess most of you are who are looking as well.
I think yeah it is not super easy to to stop.
>> If you have a very steep uphill, then it's not easy to to stop the RV.
So, um that is why we are continuing flying.
So, there's this. But there is a nice um it's almost like a a little break in the um in the sediment field there. Right.
small amount of >> lots of uh organic matter and organisms in being suspended uh in the water column >> which is also showing what a very um rich energy wise very and very compared to other deep sea areas. This is >> this is the spaghetti >> more spaghetti. So we have more The lizardics.
>> I think that is going to be the sponge name everybody are going to learn within the dive today.
>> Right.
>> Liso Dendorics Complica.
And that is another tina for there right floating up.
>> Yeah.
Let me just check.
>> Oh, look at that.
>> Oh, shrimp just appeared >> swimming by us. Ah, >> I think this a fun shaped sponge.
The one uh now close to the to the lasers.
and a jellyfish or a >> Yeah, I think so.
>> Or a tin for I bet it's a jellyfish. I think we we saw something similar passing by.
Okay, this is u a lot of um organisms uh flying away just in front of the camera which makes things a little bit more difficult to identify.
>> Yeah, but we are going still slightly uphill. So, it's now 2, 700 >> and 35 m.
>> Yeah.
>> And we still have a sedimentary seafloor in front of us.
>> Still slowly climbing up.
>> I just tried to It's >> like sitting in a sandstorm, but we can see >> every here and there.
And look, there is a sediment. So, it might have been a little bit of a sandstorm.
So for us it's really quite more appealing I would say to have rocks. Uh rocks are they for longer periods not not the sediment and in rocks you can find different species that are ceile organisms that they got attached and they produce in some cases.
This is one of the goals of this expedition trying to find um ecosystems that are like a important um for ecologically um producing like a being like a small uh trees that form um kind of uh forests. these forest they make they boost biodiversity in some of these areas. It's not that this flat well not flat but this sedimentary area is not diverse but organisms in >> different diversity and as we talked about very much the smaller animals.
>> We have reached the reds perhaps. Should we change the direction of >> um transect or do you want to continue?
How how flatish is it here? It's not really flat, is it?
>> Uh, can we right, >> but it's still a little bit of uphill in front of us. Yeah.
>> No, according the poly be it's downhill.
>> Okay.
>> So, it's now the very tummy close to >> Yeah.
>> I'm not sure if the lines maybe slightly off. Maybe it was more toward.
>> Yeah. Maybe we can have a tiny little look here at the top and then we can continue the line.
>> Yeah.
>> So, the top would be probably to our left.
>> Yeah. Is it possible to have a little look what the top looks like and then we can >> reach to the left.
>> Can we stop for now?
So, we're just going to have a little check about how >> Okay, thanks.
>> how the top of this mound looks like. If it is more sand or mud or if more of the rocks are peeking out at the very top.
>> And yeah, we're going to have a look around.
>> This is all we can do on this dive because we are looking. We don't know anything about this area, right? We are the first humans ever to have a look here.
>> Yeah.
>> You guys online are sharing that first time ever humans are looking here.
>> There's some rocks here.
>> Now this is cool.
>> There's a bunch of organizing here.
Alisorics.
>> Now I am surprised.
>> Surprise of the day.
>> And some other hexagonal. I think this white on the very bottom that you see which have um um jar shape. And this is a a roselli. One of the Oh, well that one was stoked.
>> Yeah.
>> Have you noticed this?
>> Yeah. a stove a stock storer.
>> Can we zoom out a little bit and see if we can see the landscape here?
>> Yeah.
>> So, >> so it's actually going quite a lot further up.
>> And I think this looks kind of like an old volcanic landscape.
>> Yeah.
>> Don't get those volcanic rocks and and like lava flows that have come down there once upon a time.
But with all that sediment on top, that is some time ago.
>> Who's there? Oh, yeah. This >> Yeah, that's a nice beginning. Right >> now, we can zoom in.
Look at that.
Pink fish slowly swimming and finding food at the seafloor.
big sponge.
>> And there are some large sponges here as well >> in the middle of the image. You will see in a minute some details of these sponge >> and this is >> Oh, that's big.
>> Something around half a meter, something like that. Oh wow. It's been there for some time, huh?
>> Yeah, >> it's really been there for some time.
>> And again, the sedimentary habitat.
>> Yeah.
And uh seems to be >> and again more of this >> sedimentary.
>> We certainly need to uh >> Yeah, they look like stalked cryoids.
>> Yeah, >> I think at the moment that is our best theory.
>> I can't see off here.
>> You see have a stalk and then they have like a >> Yeah, like in an umbrella. umbrella.
Yeah.
>> With different uh it's not that it's covered, >> but they have like a different uh tent that goes. Well, I wouldn't say this, >> but for you to understand, and they're capturing um food from the from the water column. Oh, look at that.
It's a >> a tenophor.
>> That's a tenophor. Yeah, that's a pretty tenor.
And more lava rocks again.
This is a strange hill.
>> So several thousand years ago, this must have been just rock and probably quite new. I don't know. Now you geologists out there, please don't >> beat us up for this. We are biologists and not geologists, but I think >> looked like a place that was very active >> several several thousand years ago.
>> Okay, can we keep going with the movement direction 045 at 0.3 knots?
How about we try to sample?
>> Yeah. If we find a flat enough place to land.
>> So we try to sample.
>> If you find the place that is possible to land, >> please let me know if you feel it's uh too difficult or whatever.
>> Yeah. Um, now that we have rocks, we could potentially stay in the place where this >> Well, do you want to go close to some rocks like this?
>> Uh, yeah, but first I need we need to identify potential uh samples that are you just tell me >> in our interest. Yeah, >> I have to again say we have the most lovely pilots who are doing the undoable for us many times every day.
So, a big shout out to our lovely and very, very, very good pilots who are helping us doing this. We're just sitting here looking at um video footage together with you guys and they are doing a lot of of work to fly this machine for all of us.
>> So, thank you. Thank you guys. You're >> very welcome.
And we always want things and they thought maybe we can make it happen. So it's lovely.
>> They make it happen. Yeah, >> they do make it happen.
>> They are really good.
>> If it is at all possible.
So 2025 are the right spot now for our first sit down and check. Yeah. But it's then we have to find a good place to sit down.
>> Yeah.
Okay. Some rocks ahead but uh just small stop there.
Maybe we are getting toward the top of this thing.
>> So, we can use uh Oo, another beautiful >> That is a jellyfish.
>> Yeah.
So, um, we're using the sonar of the ROV to see where >> the landscape is going up and where it's going down in front of us.
>> And it still looks like it's possible a little bit more going up. I should say we are now at 2,78 m. So, we have been climbing quite some meters since we thought we were at the top.
Um, and of course, even though we have really strong on the ROV, they don't reach very far because they have to go through all that water.
So mapping visually at the seafloor of this depth is like mapping your own country using a handheld torch in the middle of the night.
Mhm. You only see a very very short distance ahead of you. And this is what we are >> doing now.
>> Oh yeah. Yeah. We can just wait until we get to an area with many rocks.
>> Yeah. And this is where the sonar is getting a little bit more help for us than the lights because the sonar tells us there are some rocks coming.
>> I can see it now.
So, I'm going to try to identify specimens species that we are interested in.
>> Yeah. Look at that. Oh yeah, a rock wall. All of a sudden out of this sediment comes a wall of rock.
And look at that. Must have been such an immense lava flow once upon a time.
Wow.
Look at that. That's cool >> from China.
You can you watch to this map? So probably now we are just on this hatch.
>> Yeah, >> this is another wall, another type of terrain. I don't know if that's the your intention to go through here or >> what we want to after a while to go towards because there's another mound like this. Yeah.
>> Towards the line, you mean? Because I think we have passed this mountain. We are now going up this hill.
>> Mhm.
>> So if the attention is >> Yeah. Then we then we can see if we can do some if we find a place where it's possible to either land and sample or hang and sample.
This you have to tell us if it's possible.
>> Sediment or >> uh most rocks >> close to some rocks. Yeah.
>> Yeah.
>> Now that uh we've been through this area with rocks and we didn't identify any of the sponges that we are or creatures that we are interested in.
>> Yeah. To see anyone any rock.
>> Yeah.
>> What you want just problem is that it's like images like two dents in here to identify in advance. Uh, what do we see?
What's there?
>> That looks like one of the lollipop sponges, right? No.
>> Oh, is it?
Does it move faster? No, it's uh >> ah this is our beloved uh this is it >> sitting on a small rock.
>> Yeah, >> it's a small rock with this >> because this way we can just this this >> Yeah, I need to see where I am please.
Sorry.
that thing on the on the left.
>> So, we will make a little bit of a sandstorm when we are landing and very quickly.
>> Watch out.
>> Maybe.
>> Are you going to do you want to pick up with a minute?
>> Yes, I think.
>> I need to know. So, I know to >> Yes, I think >> maybe the slurp.
>> No, no, no, not the slurp. I think.
Yeah.
>> So, we're trying to land. Our pilots are trying to land so that we can pick up this rock with the Lisa, the species name of the day.
So, um it's almost like we're going to give you all guys a test at the end of the um of this um live uh live >> sending and say which was the species you have to learn today. Ah, >> so it's all liar dendorics, but we are going to try to sample one because as Sergi talked about, we're going to find out how genetically connected the different populations of this species is because they live everywhere.
>> Yeah, >> it's a in in this water. So in in in the Norwegian Sea, they live everywhere.
and to understand how a species that cannot travel very long distances because I mean when they are adults they are sitting someplace and not moving around they are cesile as we call them.
>> Yep.
And when they are breeding their babies in addition, how can this very widely spread species be genetically connected with other specimens of its of the same species.
If the populations are genetically dist if they are very closely related, then we can start thinking about how the contact is actually going. So this is the question we are trying to answer with this sampling.
And then since we are now landed here and waiting for the sandstorm to >> um >> disappear >> disappear, we will hopefully also be able to take a good look at those things that we think are stalked.
>> Indeed.
>> And maybe have a little bit look around about some of those.
There were ball rocks and it's amazing how just this tiny rock in this sea of mud can be the home of a completely different um habitat all of a sudden. So this is showing everybody the the difference between the hard bottom and the soft bottom animals.
Now we can start seeing our target maybe the very bottom.
>> Yeah.
>> So we have to um do a little bit of um positioning as well and then we make more um sandstorm around us. But we it will land. It will it will all be better.
I mean the strong currents that um that we're dealing with are going to make the job of cleaning this uh uh plume.
Uh it takes a little bit but um it will it will be like super clear in a few seconds. uh so that you can see how pilots are going to be surveying these organis organisms that we are interested in and putting them into a bio box that you will see so that you can get an idea of uh how is sampling um in a depth of nearly 3,000 m >> 275 m to be exact Sorry.
>> Yes.
>> So, this is going to go away.
>> This is going to go away. This >> directly go.
>> Absolutely.
>> Do you think we could potentially take the rock?
>> Yes. This is what I'm thinking.
>> But where are the lasers hold?
>> Oh, yeah. So it is >> Hannah.
>> Yes.
>> Can we bring the sex in to do these operations?
>> Yes. Let's think it will be a >> good I think we need to bring in the sexton to the the other camera that we are seeing here because it's going to be in the way of our sampling.
>> So we will take it in.
>> Thank you guys.
>> So we'll take a closeup once it's a little bit um more clear.
>> Yeah. We'll take a >> The sandstorm is landing >> or maybe not. Yeah, it's landing. It's >> It will slowing down. Yeah.
>> Okay.
Take a few more seconds for the water to clear.
We can take the rock whole the whole rock unless it's not connected to a >> connected to the planet.
>> If it is connected to the seafloor, we don't take the whole rock.
>> But if it is just um >> Okay. Where would you like it to go?
Which position?
>> What is the easiest for you?
We just uh the portrait.
>> Yeah.
>> Or do you think we're going to be able or front?
>> Front, please. Left front. Oh, right.
Front.
>> The one on the rock. You need the whole rock.
>> The whole rock.
>> Yeah. Because it's not that big.
>> Yeah. We can just Right.
>> So now you have to Yeah. 10 15 20 cm.
>> If the rock is what we see, >> if it extends down to the center of the earth, we are not bringing it with us.
>> Give it a try and then >> we give it a try.
>> So we put in a port drawer. We've got one of the coffee mugs in one of the compartments at the front. So whichever one's not populated, we really have to that one.
>> We will put it in portrait. I will also try to write it here. I have taken the notes.
>> Yeah.
Yeah. a few more seconds. Uh hopefully to get a clear view on the species that we are going to be um sampling now.
So as a reminder um I mean we've been talking about this I mean taking samples as it's super important um from the um scientific point of view so that to identify different species connectivity and stuff like that and um given the how um in the given these organisms that we're going to be surveying in here are relatively abandoned quite abundant I would say uh the effect on the population, it's it's going to be negligible. Um, but of course, we need the specimens for these studies >> and we make sure to do as much as possible with each specimen that we are sampling.
So, it will not just um be used for one thing, but it will be used for many things.
And another of those things, every thing we sample are going or maybe not every single Lisodorics, but yes, also that will be going into um a library, a genetic library of the species so that we can build a library for for being able to identify the species later as well from from genetics.
It's taking a while to clear.
>> Yeah, that's how it is when it's very very muddy and very much sediments all over around us. That is what sampling looks like in in the deep sea. You have to have patience when you are in the deep sea. Not only does it take a long time to get down and go up again, but also to work. It does take a lot of time.
Mhm.
>> And just to remind you, not only are we very deep, we are at 2,700 m, but we are also at a quite cold place. It's -0.68° down here.
>> Say, it's a little bit cold, right?
>> Yeah. I'm not sure if it's my bathing temperature.
Do you have a limit where you start bathing? Bathing?
You come from you come from Spain. So you need warm water. Huh?
>> From 20 something.
>> From 20 something and upwards. Yeah.
>> I'm not used to cold waters.
>> Norwegian children uh >> say as long as it's two digits it's okay.
>> Uhhuh. Okay.
>> So from 10 and up.
>> You're so brave.
>> Uh we're just stupid probably. Exactly.
About that one. I don't know. We have um we have a wide variety of nationalities in the um in the shack with us so we can check. What do you guys think of at a good temperature to go swimming? Does it need to be more than 10° >> if you live in the UK? No. It's too cold.
>> Yes. It would be nice.
>> It would be nice if it's a little bit more than So you would also not go swimming at minus 0.5.
>> No.
>> No.
>> Okay. There is an agreement in the shack that minus0.68° is a little bit too cold for our swimming.
>> I think we probably die.
>> Nah, but you would jump out again really fast. Yeah, that you can see with any of the chemical.
>> This is extremely fine sediment, very muddy, very um silty probably almost.
>> So, the only camera that is seeing anything at the moment is the one looking straight down.
>> Yeah, >> it's super clear now. Yeah. Yeah.
Because that's nice and calm.
Um but every now and then we can see the front of of the RV. So we are hoping that this sandstorm will land soon. It also it's talking a little bit about how um how much currents there are around here and maybe a little bit how much extra current we are making.
Give us something to identify.
A little bit more still to get it clear.
I can start seeing something.
or maybe not.
Do you have an um idea of how long you want to hang out?
How how precious is this rock for you?
>> Well, even though we've been a while, it would definitely wait a little bit longer.
Yeah.
>> So the idea is to pick the rock but also these kryoids.
>> Yes, we would like to have these stocked kryoids and we definitely think they are stockids.
One very I would say interesting thing about these stalked is that for a very long time we knew them only from fossils.
So people thought 150 200 years ago that these animals were prehistoric but they are living and thriving here. I mean have you seen that field? It's crazy right? It's a stalked preno heaven if this is what we are seeing.
>> Yeah.
>> We have to take that because we have still not been able to properly zoom in on them. But um they are definitely thriving in the deep sea.
So, um, they are definitely not only prehistoric, >> but there are some beautiful fossils of really large stocked krenids around there.
>> Yeah.
>> Some really famous big fossils of things that are almost as tall as we are.
>> Yeah. So, many millions of years ago, those uh stock crates probably were dominating the >> rulers of the sea.
>> Sea. Yeah.
But now you can mostly find them um in deeper waters >> on soft seafloor. Yeah. On very soft muddy seafloor.
>> How quick you could do this.
>> Sorry.
>> How quick?
>> I think I I can't see us getting back.
Let me do it again. Maybe just trying to pick it up pretty quick.
>> Yeah, we can. Look, now it's clearing.
>> Yeah, I think we're going to put a >> It's actually bad. I think >> I think this is as good as it gets.
>> Now we are starting to see.
>> No, I think it's going to be maybe see and not see again.
>> Sorry, but I am a little bit pessimistic about this sunstorm.
We actually move our doors up, >> but our amazing pilots are suggesting to try to sample anyhow.
This is something I wouldn't dare, but I am so pleased we have the amazing pilots with us today.
>> Yeah.
And we're going to do a grab more or less in the blind and then we can continue after that.
Is this one here?
>> Uh, yeah, that one.
>> Oh, wow. Okay. when he picks that up this camera. I'm going to put the door out.
>> Yeah.
>> Can you just zoom in so you can see where it just I've got nothing on this camera here, please.
>> Our pilots also don't see very much. So, this is um this is going to be um >> Yeah, we just seeing something that you are not. is uh the arm trying to get the rock with the other specimens.
>> So we are sampling more or less in the blind here.
>> No, it's not.
It's attached to the planet.
>> The rock is attached to the planet.
>> Oh, we've been waiting this long and then the rock is attached to the planet.
>> Ah.
Could be the drain plug as well for the water.
>> Oh yeah. You think if we pull it the water will start pouring out?
>> Yeah.
>> Yeah.
>> I think you are not interested in the in the rock itself.
>> Not really.
>> No.
>> Ooh, that was a bummer.
Yeah, it's bigger than we thought. So, >> yeah, >> never mind.
>> If it is bigger than we can pick up easily and we don't see a thing anyway, I think.
There is a piece that I broke very.
>> So, we have a piece of rock in one of the manipulators hands and we're going to bring that to our um bio boxes in the um >> see.
No, it it wasn't the the one with the sponges, but yeah, you can just >> Yeah, let's let's put it in the bio box and then we can move on.
>> Yeah.
>> Yeah. Oh, we see the hunt coming out of the uh shade here to draw out.
>> And we zoom in also.
>> So that we can see.
>> Okay. Extend the porch tray. The >> porch tray.
and zoom in on that.
>> Sorry.
>> You see Firebox one.
>> Two.
>> Okay. So, it's Box 2.
We also don't see anything here.
Oh yeah.
So the arm that our pilots are using to grab samples has done its job. Sweet.
>> Shame. It's too >> Yeah. Thank you so much for move somewhere else. It's too much. So >> yeah, same entry here. That's too soft.
>> So I say we try to move on to uh follow that next transect. So we call this the end of this first transect and then we move on >> uh slowly. We don't need to go back to the line and then follow it, but just sort of merging into the line, the next line, so that we go a little bit down towards the line.
>> So, apologies for everyone that was waiting for this s tumbling to be uh done. Well, it was done partially. We took um a rock a piece of rock in this um attached to the very bottom and then we'll bring it up and we will study organisms and also how I plan to identify um the characteristics of this uh of this rock.
But for now, we're going to be continuing with the transcept.
>> So, would you like me to head back down to the line? Yeah. Do you want me to continue along here?
>> If you if you sort of lean into the line after a while, you don't need to go straight down and then have a >> but at an angle come down to the line. So, we just call this the next transit.
>> Something like Okay. So maybe and now there is a lot of things happening at the same time because the next shift is coming to take over in 6 minutes and uh we are ending the first transect and starting the next transect.
So there is a lot of logging to do and a lot of chaos behind us.
>> But uh we are >> on our way to hopefully see something nice and interesting along the next line.
>> And as I said, we are at 2,75 m in depth.
Okay. I I do when the ship 30 came to this one.
So we are going to um do an almost >> or I can move 0 090 for now >> almost straight eastward a little bit south again >> but mainly eastward now to another of these hills >> to see if it is >> as muddy or if it is more Yes.
more.
>> If there is more volcanic rocks there, >> if there are any other >> beautiful sponges to see >> with this next transect, we will also >> at 0.2 do not >> let you have the next shift to take you through that next transaction >> and that will be uh Julio and uh Fronzy and if I know Julio he is going to say we need to sample. So, as soon as they find a place to sit down again, you can fight the uh >> sandstorm >> and see if you can find a place where you don't want to sample the entire earth >> as we eat >> because Sergy, he wants the world.
>> But it's a good thing to want the world, right? You just um we can't always have everything.
Um, so we're flying away from this area that was packed with uh this sedimentary plume >> can be used >> just because we have I mean this is really fine sediment.
I think we'll find another spot.
But we actually we bought a couple years ago. So, we will uh turn the RV around and fly towards our next transect.
>> And if we look at the map, I think did you have it? Did I have it?
>> I think it's there actually.
>> Yeah, it's approximately >> it's like 300.
>> It's a 300 m until the next mount. So we can also think a little bit about what happened back in the day when these areas were active active um volcanic areas because all of those rocks that we see are definitely old volcanic outspwings I would say. So lava that has become rock when it met this very cold minus 0.67 at the moment. We can ask the new shift.
Would you go swim in that?
>> For sure. Am I swimming?
>> No.
>> Uh yes.
>> Julio is coming from Mayorca. So he is it's not going to be his common temperature of swimming. uh with the submarine.
>> Oh yeah, with a submarine. Well, we are now with an ROV and I'm very happy to do this with an ROV.
>> Uh it's 2 minutes until cassette change.
>> Can be confused can be confused by you. Do you go ice swimming from Norwegian?
>> I have done it a couple of times from from the um Arctic floating ice. So the sea ice >> it is not a long swim.
>> No, >> but in Norway we have this idea about if you can do three swim strokes then you have been swimming.
So, um there was sometimes when we would have uh we would anchor the vessel into the ice, sea ice, and then we would all go out on the sea ice and uh one of the deck hands would have a rope around one and one of us and we would jump into the water and get helped out again.
>> It was very very cold.
>> Brave.
>> It's not brave as much as stupid. I think >> y didn't want to say that.
>> So >> I can say it about myself, right?
>> So it's uh >> uh teacher.
>> Oh yeah, >> the rest is funny.
>> But I also have to say I think I've stopped doing that last year. I only tried 4° at swb.
That's >> and that is a little bit sad actually because this is of course to do with climate change that the water temperature is raising so much there. So um >> making it possible to go swim >> flying away from this area.
>> Yeah, we are flying away from the snowstorm. No, that's not the snowstorm, the sandstorm. Do we go close to the seabed on this or just head down to the line?
>> Oh, no. Yeah, we can go.
>> Is it possible to go close to the seabed?
>> I guess it depends. Yeah.
>> Yeah. Up and down all the time.
>> Yeah. Yeah, that would be nice.
>> We're losing the >> the view of the organisms in there.
>> Yeah.
>> Yeah.
>> As close as you can.
>> So, 10 seconds to start recording again.
>> Yeah.
>> And that means uh Sergy and Ana Helena are handing over to Julio and Francancy.
>> Yeah.
>> And you guys out there enjoy because now you're getting the uh real team coming. Well, one real team is leaving and one other real team is going. So, let me just lock this.
>> So, more exciting views coming up >> once this dust is nice and left away now. Yeah.
So, thank you so much.
>> And so crowded here. We have to get one out of the chairs at a time.
Thank you guys.
>> Hello. So, >> Julio and Clancy are on shift now and also starting a new transact thing.
So, Yeah. Ready to go further exploring more of this volcanic area here.
>> Um in parallel to Yeah. So just keep >> and seeing what else we find.
>> Okay. Well, finally that was where I said >> okay maybe.
So yeah on this trajectory happy.
>> We're currently >> discussing with the rough pilots also because we're on an exploratory dive. We can experiment a little bit also what we >> see in our bimetry data. through the topography of the seabed, what we think is interesting to go along. And we see, for example, some uh some cracks, some crevices, some valleys in this area that look interesting on the map at least.
And yeah, since we're the first ones out here, we just want to have a look there and see what it looks like on camera and not on the not on this um yeah, within the trend. That's a metric map.
>> Is it good?
>> Yeah, I need a pencil. Ah, here. Yeah.
Yeah, I have.
>> You have multiple pencils here by now.
>> Okay.
>> And all our paperwork too. Yeah. All goods. All good.
Proper office here.
>> 090.
So we'll clear your tracks now.
>> Okay.
>> I think do we have a very some holes in the settlement there?
>> Very sedimentary. See >> actually now we are going more like 0.
That's a hole. Some holes.
>> Somebody living on over there.
>> M.
Yeah. Even though we mainly see sediment here, it doesn't mean that there's no life here. Uh, a lot of life actually lives in the sediment or below or small organisms on the sediment.
But we cannot see everything with our camera here.
Right.
But we're trying and zooming in really close on what could be. Could it be a sponge?
>> That looks to me like a bigger sponge.
>> Bridge A ROV.
Let's >> see if I can focus this.
>> Can we slow down to 0.1?
>> Yeah.
>> Just for you to understand.
>> Maybe we just have to get a little bit closer.
Yeah, that's an asanma.
>> I'm loving that already.
>> Mega atriala.
>> Ah, yes.
>> And then we have the the community of little sponges growing on the rock. This is where potentially the new species is.
>> Mhm. But it's too big to sell.
>> That's too big. So, we are looking for a a rock that is d and little bit smaller in size so we can grab it with our hand.
So, on one of the previous dives, we uh we sampled a little rock and we found potentially undescribed species on there. Right.
>> Maybe. Yeah. Looks like looks like we still need to to get DNA out of it and do to do a lot of work, but it looks quite promising. It's a it's a genus that is not known so deep. So, that makes things a little bit easier in order to tell that it's new. Uh that's why I feel that it's really that really is a new species because uh the deepest that we are aware of uh was found around 700 m and that one we found at 2,800 m.
Uh and it's also the first species of the genus reported from the Arctic waters. So it looks good, but we'll see.
Um, so one of the goals in this dive is to find that sponge again and to see if we can get uh specimens informally >> so we can see the >> the cells.
>> Okay. Can we change the direction of this movement to 150?
>> So that's why we're on the lookout for also for some Yeah. little rocks where we can hopefully find this and shed some new lights on the yeah on the species diversity down here.
But as soon as you go to those deeps, it's quite common to find new things. Um you have to think how difficult is to sample here.
Um you need to come so far with a big vessel. Um so historically this kind of uh depths were not uh available for for people to sample but now we have this technology and we can start to to understand what's going on.
>> Which speed are we going at at the moment?
>> Which speed?
>> Uh 2. Okay, that's fine, too. Okay, >> maybe even for these parts from from outside at least we could speed up a little bit or rather >> Well, now the Rocky crop is coming maybe to see that month.
>> True. We also have a Yeah. Echo sounder.
No, >> sona.
>> I always get confused. Yeah, a sonar here. uh to to see like what type of um type of bottom is coming up. And we see some rocky area coming soon and we can also see it on the camera. So, we'll look at that.
>> So, we are really going through the pictures.
>> Yeah, it's fine for the moment. If they can go a little bit closer closer, that's fine. But it's only on you.
>> Yes. So, >> do we have little lollipops or are those the No, >> I'm not sure. That would be hard to say.
That more like a or the cry.
Hard to say. Yeah, hard to say.
>> We could >> something's living there >> that we know.
>> Potentially try to collect one of those, but this sediment is so muddy that it's a it's a nightmare. Every time you land, you get this cloud and then it's forever.
So, so I think >> yeah, we want to be really >> mindful about our >> should try to find an area that is flat enough so they can land but it's rocky >> so we can have some visibility of what's going on.
>> That sounds like a good plan.
So that looks to me like emilious amuse.
>> Is it on our list? So we can just >> I don't think so because we identify this species two days ago. So Ami amigoserus.
>> Alo.
>> So you put an H at the beginning.
>> Ah the silent age of the Spaniards.
>> Yeah. No no here.
>> Haming.
>> Yeah. Perfect. Arerus.
Ah. It's fine.
>> You will know later on hopefully. All right.
And do we have more? No, it's almost >> Thought I saw more interesting sponges on the lava.
>> Yeah, that's what we want.
>> Rocks.
So, Francy, we will try to clink a little bit.
Mhm.
Yep.
The area is coming up that we saw at uh at the beginning just a few minutes ago on our on our map with um some cracks, rifts on the surface. Uh and we're looking at these rocks now are starting to look at them.
climbing up a little bit.
>> You see all these little dots that grow on the rock?
>> So, probably our new species is >> one of those.
>> One of those. Um, >> yeah, we'll need to get much to be much closer.
>> And which sponge would that be?
>> That's it. Um, >> I don't remember how it will come up.
But I might be wrong there >> cuz Julio here's our sponge expert or one of our sponge experts next to Seri who was just here and Paco who will come up later likely and a little stem Yeah. You see that it has a stem?
>> Mhm.
>> Try to catch it.
>> Yeah. One of our Could you also call it lollipop because it had a It has a stem or is that just for the >> uh Yeah, I guess I mean really is really big.
>> Yeah.
>> So, it's a very large lollipop. M.
>> Wow.
Is it known why they they built stems?
Is it to be far more far away from the settlement and then have an easier way of filtering?
>> Sure. Can we change the direction of this movement to 120?
So >> hold on.
>> Yeah, >> that's coordinate.
So we >> have cryoids there now.
>> Yeah.
>> No, I mean >> many of them hanging out together.
>> I can only go off building a letter or so.
>> Did they saw Kuts in the >> Okay, thanks.
>> Sergey and did they saw Kuts and >> um not sure.
So yeah, stems are to to stay away from the mat. Uh so you don't want the mat because the mat will >> will block your aquifer system. So you build the stem, you can attach to the bottom. That's very uh useful. And then the main body is away from from the ground. So >> you can still feel the feet, >> especially in those habitats here in these bottom characteristics.
>> Exactly. Exactly.
But you can tell when you see a rock, there are no stems on the rock.
Everything is like a crust.
>> Yeah.
>> Could you zoom in on some of the >> Sure.
>> of our button dwellers.
Hard to focus there.
>> Yeah.
So with movement >> ah there are there are thing little critters sitting on the stem.
>> Yeah. There's a couple of things here.
Our colleagues were mentioning that this may be a kinoid.
>> Yeah.
>> But in this case there's some something growing on it as well.
>> Maybe some of Anelena's and Anelina's beloved amphipets.
>> Maybe. And I think I saw a brittleto star over there.
>> To the to the right?
>> Yeah, >> that one.
>> No, there was a really tiny brittle star escaping, but couldn't see it.
So, we're still climbing and we see some more rocks coming up here.
We're at the moment in a really deep area of uh of Mon's ridge on the midarctic ocean ridge that spans all across um like is part Oh, hello.
Uh yeah, we're so at the moment um on the mid-Act ridge on the Moon's ridge, part of the north uh of the Atlantic ridge that spans all the way across and uh it's a very very slow spreading ridge in comparison to some other ridges that we have um so for example in the Pacific and it means that The tectonic plates here are like drifting apart slowly.
Uh, and there's volcanic activity uh underneath. And this is also where >> yes, an enemy sponges. Yeah.
Yeah. And here we see the remnants of u of the volcanic activity with all the the lava rocks.
>> That orange one I never seen before.
>> The orange one.
>> Yeah.
Okay. We see something similar. We try to stop.
>> Maybe on the one that's coming up.
There's a lot on it.
>> But I think is that we need a small rock.
>> Yeah. It's going to be it's going to be tricky.
>> But there's the sedender looks on there.
That's just for logging.
>> Um, what what do you think about stopping around easier?
>> Yeah.
Maybe better on the rocky than on the mud or the problems.
Yeah.
So because we want to sample more of the liodender and also have a small rock with um what we believe are unknown sponge spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe spe species, undescribed sponge species. We're looking for a good place, a good spot for stopping and for taking a small piece.
>> See that rock? But you know, you can >> I prefer to to wait a little bit. Yeah, that looks that looks good, but >> it's tricky for them.
>> Yeah, it's very un uh Yeah, not not easy to stop here with our big ROB.
>> These are also interesting crusts on those on those um rocks. as possible.
Just ask.
>> Yeah, we can see again how easily the really fine sediment is >> swirled up here.
>> Yeah, that's why I want to see the problem.
>> Oh, I can like a fine powder.
>> So, it goes to the left.
>> So, if it goes to the left, >> but it's only I should try to spot something.
>> Very temporary here. the right.
>> Yeah, I don't know.
>> More rocks piling up here.
>> Yeah.
See that?
>> Yeah. And on the sides we see a lot of of the small sponges all over >> and also sediment on the on the rocks themselves. So yes, they've been around here for a while.
>> Yeah, but the last time you worked for >> So it has to be months.
It's going to be right.
>> Julia and the pilots are discussing a little bit >> what could be a good area.
>> We got the need to push up.
>> Yeah.
>> Yeah.
So us two over here, we're mainly logging what we see where we can steer the camera that you can also see with our joysticks.
>> But the real work of the steering uh and the handling of the rock of our robot are uh the people over there doing.
So they're the real >> rough experts here and guiding us through this uh unexplored landscape >> right to collect props today.
>> So we're settling down now.
>> They're trying but we have probably sitting down yet. You want me to sit down here?
>> Okay.
You're not going to see anything.
>> So, yeah, we're not we're not even settling down, but nevertheless, the sediment is so fine. That is >> it's just steered up easily.
>> I'm just I can stick a stone, but I'm just going to be >> if you find place that you say, then you tell me. Okay, we can see some fairly level.
We probably can't. So, we'll keep going because that mat will take forever to settle >> relatively.
>> Yeah. The problem is that we cannot land on the rocks because the AR has cables and has a lot of devices that could u potentially damaged. Uh but our pilot will try to find um a place that is maybe a little bit less mavy and good for them to settle.
>> That sounds like a good plan.
What do we have there? A biggest sponge in the distance.
>> Yeah, that's >> interesting shape.
>> That's one of those emilidious aroperus.
>> They're really common.
And these grass that are a little bit larger, >> that's a mid. It's a family of demo sponges. The demo sponges >> as I learned the sponges of the people because uh the sponges that are sometimes used also in the bathroom or in the kitchen are >> can be made of demo sponges.
>> You see that?
>> That that looks like the middle.
>> Yeah, that looks like four bus to me.
>> Forbus. E H O R E I >> Do you want us to stop here?
>> Yeah, perfect. Perfect. Well, thank you.
Thank you very much.
>> We are coming to a halt.
>> Okay, we just stopped here.
>> Ooh, and we see nice rocks everywhere.
>> Bridge Arabi, go ahead.
>> That's perfect.
>> Can we stop for now the movement?
>> Okay, now we take our time.
>> There's some sediment. We will wait until it settles.
We will have a nice view of everything.
We'll think about what we want, what we don't want. Uh I I saw some little small rocks. Very promising.
Uh so yeah, let's let's wait now till we got some visibility back.
Rocks, rocks, rocks and lots of rocks.
>> Remember the problem fra Saturday >> and we have so far taken already one rock sample. Right. That was our Anelina and Si took it.
>> Sure.
in the end.
>> Oh. Oh, I'm filming with the microphone.
I just realized. Oops. Uh, sorry for the noise that I potentially caused.
I think they put it in the front drawer.
Yeah. So, we have one in there already.
>> We have nice nice sheets here prepared for the different compartments of um bio boxes as we call them. So the different boxes by for biological samples and um to keep track of what is in which chamber where we have printed out some templates >> and created some nice paperwork here which will be very important afterwards for knowing also when the rough comes back on deck because then also the real work starts for the scientists to get all the samples out of the bio boxes out of the compartment get um to the lab, get them um get them with the labels that are um correct so it all matches up in the end.
Do you need something?
>> No, it's okay. I'm just taking note of the coordinates.
>> Sorry, >> that's also right in front of me is a >> it's a screen with our coordinates and the depth. So, we're at the moment at >> 20 uh 72° north uh and at >> Yeah. at 2,700 m step and all is noted down.
>> Yeah. And we just need to be nittygritty about our logging here also for the later analysis that will take place. and um all of that.
>> There you go.
>> It starts to clean up a little bit.
>> Sorry.
>> Start it starts to get better the visibility.
>> Oh, here.
>> Here.
>> I can move my camera.
>> Now we get a clearer view. Let me see what's >> of some of the rocks.
>> Um, so maybe we should tell Jason that there's something interesting here when this clean up.
Talking about the new species.
>> Yes, >> maybe.
>> Ah, maybe.
>> There's still some time until this cleans up.
What was that?
>> Yeah. Was that just >> I don't know.
>> Was like a crustaceian.
>> Yeah, it could have been. It It reminded me of a seahorse, but I was like, Me, too.
>> What are you doing here?
While we're waiting for the dust to settle more, since I was talking about the bio boxes, uh we have different setups possible here with the roth. We have two bio boxes in the front um that can be divided into several compartments.
And we have at the moment four on the left side and uh four on this on the right side. And we also have more compartments in the back. Five more um that can be used as well.
And uh yeah, we have therefore quite a bunch of possibilities to take different samples and be also clear in dividing them from each other because sometimes you want to be very uh we want to be very clear which sample came from where. Um sometimes it's also possible to to do that by oh we have a shrimp swimming through the picture. By the way, if we have two very distinct species or samples, um then they can also sometimes go in the same bio box because then later on we will know anyway that one that sponge came from that area and that other sample came from that spot and we cannot mix.
Oh, we really see nice here the the ice of the shrimp as well. All the very ghostly eyes almost yellowish white.
I should look this by the way and not look not just stare at it.
There's another one over there.
>> H >> it's another one over there. You see?
>> Ah, there. Yeah, there we have another pinkish dot.
>> Is it uh also is it a canella sponge right of it? Where?
>> Uh, it's not visible anymore, but there was like this round little ball, but it could have been also a sedimental I think it was more more likely a sedimental rock.
>> Okay.
>> I start seeing sponges everywhere.
>> I don't think we have here.
>> No, we may.
>> Yeah.
>> Too deep.
>> Surprised too deep >> until which Soella is more in shallower waters. Not really shallow but >> not not shallow but no this is super deep >> there there may be canelas that that deep I'm not sure about that but not in this area that I know so far so there are in this community there are polyastia there is an alicona there is the amigilius >> there is the stellador uh I saw Oh, a couple of immedias >> all on the that rock >> on on the rock that we collect the other day and the communities. It's the same as we are seeing now. I think that the other day was a little bit richer >> maybe or more dense.
>> Uh but this may have to do with the with the sediment. So this station is more sedimentary >> from behind.
>> And does that so does that block the sponges from from even settling there? Well, a sponge wants food, which usually comes with the current and substrate. Uh, so rock is better than sediment than mat for instance.
That doesn't mean that mat is not okay, but then you need special adaptations >> like a stem.
>> Like stem. Yeah. Um, some some produce a lot of mucus. So when there is a lot of sedimentation, they just release mucus and then Yeah. Then the the the sediment doesn't go in. Mhm.
>> Uh but ideally you want rock and you want a lot of current bringing food.
Uh >> and because sponges are very well adapt to this kind of depths, they don't have so many uh competitors for space.
>> Mhm.
>> Uh competition for space is is something that is very widespread in marine habitats.
>> Uh so some sponges are toxic. That means that when they grow they release secondary metabolite. uh toxic molecules that may kill what whoever is growing next to you. Uh and this is how they compete for space.
>> Cheeky little sponges.
>> But this mat is going on and on and on.
It's getting worse.
So we wait.
5 minutes and if nothing happens then we move on.
>> What do you think? We wait 5 minutes and if it doesn't clear >> I mean if you spot something and you can probably get it fairly quickly while we got >> before everything happen.
>> Yeah. Yeah. The the thing is that I really want to close up >> close.
Okay.
So for some uh samples we want to take it's also important that we that we see before what we take especially >> for the species which we don't know yet >> because um then we can tell from the pictures how they or from the video how they looked like while they were still down here >> in the water and compare it to um to to the to the samples we have taken them and have a so to say inc2 um comparison and yeah and that's that's important for the species that we don't know yet right you can probably explain it a little bit better why we want to have also a picture of our video of the >> because sponges they change a lot the shape when we have them on deck so what we want is to characterize the community. Um for that we need to match what we collect with what we see. Um so we can we don't need to be collecting all the time. Uh at some point we'll we will be sure that what we see is what we collect. But for that you need to take many closeups and and then to sample and then you you are like okay this thing that now I have in my hand is that little thing that I saw on the video like that you can then process the video uh the whole video without being collecting all the time. Uh and you can be saying here you have these species here you have two here you have more this area is more diverse this species that I found here is repeated in the transet these kind of things. So it's quite important.
Uh but I don't think it's going to happen now because this is getting worse and worse. So maybe we will just move on and see if we can find a place with less sediment or maybe where the currents are a little bit more nice for us to clean uh this cloud. The thing is that we we the the arrow needs to have the the motor on constantly >> and I think that the cloud is happening and happening and happening because we are we have the motor on.
>> Mhm.
>> So >> yeah. So we have these propellers.
>> Yeah, exactly. M >> and on the other side we cannot land on on the rocks because it's dangerous for the ROV many cables hanging on.
>> Yeah.
>> Uh >> we don't want to get entangled.
>> So it's a balance. Exactly. It's a balance. U but yeah we move on.
>> Okay. Yeah. We just show Okay.
Yeah, that was a try. But we move on and have a last look at the at the little sponges.
So after work we're gone the sediment will flow will go down again relatively quickly. So yeah, matter of some yeah, minutes to an hour or so probably.
But since we're constantly staring with the propeller that the ROV has the really fine powdery sediment up here, >> it's it's more tricky to sample in this area.
>> I'm taking off to the right down below slightly. Someone border line for me might be okay.
You can see anything.
>> N not really.
>> Okay. So now it's better because you you actually I've reduced my downs. I'll get movement there. Perfect.
Getting bored around >> cuz obviously that's closing.
>> Yeah, but now No, it's okay. It's okay.
We'll find out another place.
This is actually enough to some.
>> So, we're looking a little bit more still at this area >> with interesting sponges on the lava rocks. um and down.
>> Yeah. Discussing.
>> Okay.
>> If we're moving further after all or if there might still be a way um or how we go about in the for the next sites to make it easier to >> meaning that if now that we you'll need to set it again.
>> You tell us what we want, we pick it up, >> but we can pick it up quicker than >> Yeah. But I just >> No, because in in the other side there was a little rock but by Noia >> outside in front of the right arm. Do you see anything interesting?
That's the area that we can reach.
>> No, those are giant rocks.
>> But we we we're going to have the same where we move to or if I move forward or it's going to disturb the seabed again.
>> So we can have the same but you're going to have all everywhere down here.
I mean this is what we want >> but this is a this is not even a rock.
So this is >> zoom up from that. So >> this is this is our crop.
>> Yes. Unfortunately we cannot take just a gigantic rock with us. So >> that's >> so we have to look out a little bit.
>> Right. So you want a whole rock as many things that has to happen at the same time.
>> Right. Okay.
>> It's okay.
>> Thank you.
I think it's cool on these on the rock in the middle, for example, we still see some of the layers that the lava went through before it dried.
Okay, guys.
Actually, now we moved again cuz we were >> and a lot of sponges on the little ones.
crossing a line here as well.
>> Sorry. Going across the yellow line now.
>> Okay. If you see >> Yeah, you can with the line. Yeah.
>> Do you want me to follow the yellow line?
>> Yes.
>> Yeah.
>> Thanks. Yeah.
>> Yeah. We'll see the other crack then.
>> Lots of blood sponges here.
>> 15.
Oh, those are nice and interesting sponges.
>> Can we stop for a while?
>> They look interesting, don't they?
>> And some worms in between. There must be also Assyrians. So this one in the center is an Assyrian. I think the one that is a little bit more whitish >> the new transparent.
>> The new species.
>> Oh.
>> Oh.
>> Oh, there was a kryinoid on top.
>> Oh, there was a like there's a little cave or bridge of lava.
>> More kryoids sitting over there.
>> Yeah.
>> Just flowing in the currents. to climb this to see how power.
>> So we now climb the rock wall and >> on top. So we see a lot of >> see a nice sponge.
>> Do you know what it is?
>> No. No. That's why I asked them if we can take a little piece. Can we just a little piece to see if it's a new species or to see what it is?
>> Is it a fan?
>> Yeah, it's a fan shaped fan shaped sponge.
>> Yeah, sponges have a lot of different uh forms. Some of them were more like cubes, others like crusts, others like >> We actually have frogs. You say fancy.
We actually have frogs.
>> Oh. Uh, >> but I don't see any >> three samples.
>> But I don't see any sponges on it.
>> But I see different different uh kinds of rock.
>> On the vessel. He will be happy.
>> Yeah. Look, there's like the cracks were filled up with some other kind of rock composition afterwards.
>> The polar rocks underneath me.
Yeah. And I'm trying to see whether or not we got a big drop.
>> So, we're uh interested in the sponge we've seen before that was quite fan shaped. Um and we don't know what it is.
And especially the sponge expert doesn't know what it is. So it could be something that is yet undescribed and that's why we are trying to settle down now >> and try to take a little piece of it um to find out what it is if it's new how the spicules look like that we talked about before. So the little um yeah the little glass spikes um sponge us sponges usually create um and by looking at those under the microscopes at these little specules we can the sponge experts can tell which species it is because they're very distinct. Um >> yeah, none is like the other.
>> I sometimes think of it also as like snowflakes also when none is like the other. But um yeah, if you see the different uh forms that these spicules can take, it's really amazing. I think >> um what >> yeah what just nature so to say uh created.
>> Yeah.
>> Yeah, we can. Yeah, we can. Yeah.
>> But to get this, we have to create this little sandtorm again. Just like that.
>> Plus, we've got some rocks there cuz we come >> and we need to discuss uh quite in detail.
>> What is a good position for the ROV to land because we sometimes have >> Yeah, we have rocks around us. I need to pay attention to these.
>> Yeah, we don't want to coming up. So I need to go around.
>> We don't want to damage the RV or >> tilt over or something like that. Um >> so we just need to see what works best and also uh how we could potentially sample this.
And if we did sample um a little piece of that sponge, um sponges are very very good at regenerating their body parts.
Uh they can even from just a bunch of few cells or even single cells regenerate their whole body. So yeah, they're they're pretty cool in that regard and in other regards, I guess, as well as uh Julio would probably tell you.
>> Yeah, we won't see it again. Let's just give and shrimp, I guess.
>> I mean, he's over there. So that >> can you straighten up your camera?
So then I can then rock.
>> Oh, you mean this?
>> Yeah, because I have no viz. This is looking down.
>> Okay. So >> I've got a watch that I don't rocks.
Okay.
>> Okay. So if you turn >> that out straight, >> put it straight.
>> The HD.
>> Put the immersive camera back.
It's okay.
>> Just have to think of it before we take the sample.
>> No, if we're if we would be ready to take a sample, we put it back in. But >> now it's recording.
>> Is it on? H. Sorry.
Now it's recording the the camera. Oh.
So, we are we are still trying to land at the moment.
>> We're trying to see where it is.
>> Trying to see where it is.
>> See where it is. I can't bl plant.
>> No, better not.
>> Yeah, it's a tricky area.
>> Oh, I think that came back.
>> Yeah. So since there are rocks underneath us and we cannot really see them at the moment and we have to regain our orientation uh we just have to be extra careful in this dive with um the sampling that takes place in our navigation.
for a sec.
You can have a look with your camera when you spot it.
This is nothing.
So honestly >> the thing is cuz we're in a canyon and I was on the top I just can't go in >> because if I go in the canyon >> Yeah.
>> can't swear game over.
>> Yeah.
>> You know if you get caught >> Yeah. The characteristics here of the of the bottom where we are right now are quite tricky because it's like a little >> little canyon and we cannot go in there with the ROV cuz then it's like >> uh yeah hard to get out of again when we're surrounded then >> by just got on at the moment. Yeah, >> we had visit something really close. We just lost this, >> but there's a canyon down below us >> and it's just over just over the precipice of the canyon.
We've come forward a bit. I know.
>> And we're at the moment at the handover for the ROV shift. So, one shift is sending over to the other. So, that's also why we have more >> people here around. Um and the rough pilots that we have before they're going on their welldeserved time off they work in uh 12-hour shifts because tech it's not very exact.
>> Yeah. From 12 to 12 >> and we were converging to >> so some of them now have to follow the >> they're welld deserved end of working day and the others are just starting it.
>> Yeah. Yeah, if we find something interesting, we may deviate a little bit from the lineise.
>> Just some backing the current stick along that line.
>> Hello.
>> How are you?
>> Here we go again.
>> Yes. Rock taking over now.
Sorry guys, >> huh?
Good.
>> Thanks a lot.
>> Oh, yeah.
Okay, we keep moving.
So we continue our search for more suitable rocks.
tricky because But it's because we have very very powdery fine sediment here that is very easily um >> yeah distributed in the water column uh dissolved not dissolved but uh suspended suspended is the word right? Yes, >> pretty suspended.
>> But yeah, after we leave it will also easily settle down again.
>> Sounds >> because we're not >> we're just above it actually and it's already >> piling up like this >> or suspending like this.
>> Yeah.
>> Uh yeah, >> but of course like this we cannot see anything and that's not very good.
bridge RV.
>> Good afternoon.
>> Good afternoon.
>> While you were um >> navigating and um discussing, I was telling like for the for the case that we would sample a little piece of sponge that sponges are really great at regenerating their body parts.
>> Yes. Yes. That that that piece will regenerate without causing major damage to the sponge. That's the advantage of being of not having true tissues >> meaning that every part of the body can regenerate very easily.
>> Yeah.
>> So even from like one cell some cells they can just >> grow all all again.
>> Exactly. Cells are not that specialized in the in the sense that for instance we humans are cells when they're specialized they they cannot go back and they cannot switch between type of cells. So a brain cell is always a brain cell. Uh but the sponges they have a little bit more of flexibility in that sense uh because they are more um let's say um not simple but the the piece wise it's a little bit more simple. Uh so that that has many advantages.
Um so yeah you can break a sponge in many pieces and and the pieces will also generate. So you can make clones actually. You take a sponge, you cut it in parts and then you you put that parts in different parts of the of the sea bottom and they will create a different sponge. Every one of the parts they would create clones with the same genetic information.
>> Good afternoon again.
>> That's pretty cool.
>> That's why we we try to >> when we see a large sponge, we try to collect just a piece >> and then we know this is not the end of the sponge. It's not it's not hurting very bad. Uh >> and like having a wound forever. So, but it's just going to be like, oh yeah, I'm going to grow that back, I guess.
>> And for us, that's more than enough. We can check the skeletal elements, so the morphology, we can check the DNA.
We can even check if there are secondary metabolites. So, interesting chemistry.
uh with just a piece of the sponge without killing the the individual.
>> And isn't it also that these secondary metabolites they can even be used also in pharmaceutical ways.
>> So they can also be >> used for because the sponges the the sponges have it to also have uh some forms of defense mechanism against Exactly.
>> So they kind of run away. So that's the way they protect themselves having these molecules >> and you can use those molecules for many different um things like against uh cancer uh against >> as an antibacterial drugs >> uh as uh sometimes um some of these molecules are very nice to avoid >> things to settle on the wood of the ships and the vessels.
Uh so there are many applications.
Uh so we always say that the biological diversity of sponges uh is in parallel of biological of chemical diversity.
So this is also a resource that sponges have that we want to to protect uh not only for the environment but also for ourselves because we can learn from these molecules and uh produce new drugs >> that could potentially uh save lives and be used in the bio uh biioharmaceutical market. Yeah, >> that was yellow. No, I think the one with the yellow So I end it, but >> but >> but I am a little bit afraid to stop.
>> I'm really so soft, guys. The sediment is just going to go everywhere. Trying our best here.
>> Yeah.
>> Come down a little bit.
>> And we saw interesting little little mounts in the soft set, I think.
>> So an indication that something's living there underneath. Oh, and sponges coming up in the distance on the right. What was it? Do you think >> there's a big big mound coming up?
>> 25 big rock.
>> Yeah. Right.
>> We have bigger rocks coming out.
>> The fish.
>> Mhm.
And another one there. Can you zoom in a little bit?
>> Definitely a fish.
There is a field of stems.
Jelly.
>> Yeah. Kind of a jellyfish.
>> Very dark jelly.
What are the more pinkish?
Uh, no, it's just one. It's a shrimp.
>> Oh, shrimp. Yeah, that makes sense.
Oh, a lot of them.
>> But they are bigger than the ones we've seen before, it seems to me.
Or maybe we're just closer.
>> So now this >> is it amigos.
>> Yes.
Aarus >> and Lucendo >> and it's >> our spaghetti sponge.
Is it really a like common name for this or did someone just make like from from us make it up or >> It has no common name yet. We we need to think about one.
>> Spaghetti names. Spaghetti sponge seems suitable for me. I get this punch >> and those patches.
>> Yeah, that's >> encrusting or >> that's the same community of encrusting sponges before >> and the shrimp >> and the shrimp.
>> Many shrimp. Shrimp. Yes.
fishies.
>> So they have an asma.
>> Oh, you can tell that >> see the big one in the >> mega >> potential. Yes.
And here this is the the community that we are looking for.
>> So the new species is the more like orangeish. Mhm.
>> You see?
>> Yeah.
>> Ah, like on top there and there >> or on the left.
>> But you also have little amigious. So they are also like kind of oranges. So this for instance is not >> little I mean the am I jealous a couple of >> Yeah. The little ones look like that as well. So >> that's why we really want to stop and have a closeup.
>> We can sit on top of the rocks.
>> Yeah, that would be perfect. Oo.
So we stop 11057.
Yeah. Okay. So now we're stopping on on on a rocky oak crap. Maybe would be better. Maybe we won't craft so much mat this time. So the current is up the uh The current is coming from the starboard side.
>> It's clearing out. Great.
>> Well, as the current is coming from the starboard side, we could always spin the head round. So, it's coming into the the current is coming into the vehicle.
Okay. So if there's any disturbance, >> we're discussing some strategies what could make it easier for >> our little sandstorm to settle for.
>> But if you are not okay with stopping, you just stop because I don't know all these things.
So >> if you want to stop or say yay or simple So the little ammy jellos we saw those are still baby ones then >> so to say.
>> Yeah they're small small specimens.
>> We've already seen some that are now in their reproductive period now. So that they're you seen some sponges that have >> the endors. Yes.
>> Or even eggs inside.
>> All right. Yeah. Yeah. Yeah. And Sergey was checking the endors which is the species we are targeting for our connectivity study. And some have eggs uh and others I think uh he saw sperm.
Uh so that's very interesting meaning that something's going on. Maybe now is the time they are reproducing.
So yeah, all these things will be processed on land and it'll take our time.
But yeah, it's very promising.
>> Mhm.
>> And we see also the different ways how sponge reproduce. Some of them they just clone themselves or they like butt and then they have a >> Yeah. new sponge falling off and others are like broadcasters so to say. So some are females and some are males and then they release their sperms and eggs and hope that they find each other in the in the water and then create new little sponges to settle on a suitable substrate.
I guess >> bing uh is widely spread in sponges and is a way to produce clones that little a little piece of yourself that will fold into the water and try to colonize different place. Uh but then you lose the advantages of sexual reproduction which are becoming adaptable to the changes of the environment.
>> There are more mixes in the gene flow.
>> Exactly.
So, so yeah, it's a balance.
>> So, you would say more?
>> I don't think so.
>> No, because I think that we'll learn I'll ask him more about sponge reproduction when he has more time, I think.
>> But yeah, some sponges are hermaphrodite. So, they are both male and female or neither in one. And some are uh they have distinct sexes. They are male and female separately.
Okay, we we move on because it's not going to clean.
>> Yep.
>> There's more rocks on that.
>> When you see the white, there the rocks.
>> Oh, yeah.
>> Hard to contact.
>> Perfect.
>> So, maybe we can try that. The other side.
>> So, we're moving further on our hydrothermal vent area, field area.
So this old uh volcanic area where we can see some of the lava rocks.
There they are. Yeah. There you go.
I mean, those roads would be perfect for us, >> the little ones, right?
>> Because Yeah. Because the small wise.
>> So, we want to sample little rocks because we um we've >> I thought there was Why do we want to sample little rocks for you?
>> Well, because we are we are looking for this new species that appeared the last day and it grows into these rocks.
And we want to uh do genetics genetic analysis so we can find out if it's indeed an unscripted species and about characteristics about um their structures.
>> Yeah, it's okay.
>> And yeah, they grow on these rocks here >> and we want to sample a little >> we'll find a similar community. So yeah, I'm happy with that. Yeah, little bit less muds.
>> So I think now we're moving a little bit over sediment area and then we find some rocks again.
>> Yeah, but I think we will not stop because it's every time we stop the the mat reach Japan and >> uh it's pointless.
>> So close yet so far.
How can I tell the baby amigellos aera from the potential new species underscored species >> that amigerious they produce?
>> Yeah. Well, I think that are bats like a little projections on their skin while emus is smooth on the on the skin level.
When you had them on your hand, they are very different >> because emid use midious um the new species uh has a lot of new fish.
>> Yeah.
>> While the very slimy.
>> Yeah. Super slimy.
Yeah.
>> Yeah.
Yeah.
>> And I think we're almost at the end of our second transect here in this >> hydrothermal field area.
>> Yeah.
>> Interesting.
And we see another rocky valley here with the sponges positioning themselves nice in the currents.
There are not so many carnivore sponges out here, are there? I've seen some >> but less than before. Seems to me >> less than in the coral reef for sure.
Coral reef was something spectacular.
Have you seen that before?
>> So many carnivorous sponges particularly unique.
>> Many many. Yeah.
>> And yeah, that was about 1,000 m depth.
So now we're much deeper. Is that because carnivores fungus are more?
>> No, I think it has to do with the food availability. Oh, so in the coral reef there was a lot of uh marine snow >> and a lot of current more than here I would I would say.
>> Oo, a lot of cryoids there.
>> Okay. Yeah. Try to get those tricky at the moment.
Goodbye.
>> Yeah.
>> All hanging out there.
>> And another How are we going about with the end of this transact? Oh, sorry. Did you >> uh Yeah, I think that we are good to stop the transect.
>> Yeah.
>> Because well, what? Oh, okay. We have a listender. That's No. Where?
>> Yeah. to the right.
>> Sorry. Uh because we're almost at the end or like parallel to the end of our transect.
>> We're not going north.
>> Yeah. Then we'll mark also that it's the end of our transect here and then we can start moving there now.
>> Yeah. Turn.
>> Cool. Thank you.
>> Bye.
>> End of trans.
>> Yeah. End of trans two.
Okay. So now we will keep going to to the artist.
>> Yeah. Yeah.
>> Thanks.
>> Do you have the um the photo profiles?
Uh, can we change the bearing slowly?
>> Because we have a nice folder where we printed out all our little uh our different transacts and their profiles gradients. They have this.
>> Yeah. So, now we're moving So now we're are going to move northeast for about 300 m and there'll be more balance and crevices coming up.
>> But I think we'll have some time going over a rather sedimented area before that.
>> So much 100. Yeah, we're going to be at about 2,700 m depth. What's >> we we consider that we have started transit trip or do you prefer us to go a little bit more?
>> I think going to the north looks interesting.
>> Yeah, we are going north. But uh are we going to the line >> or we are or we are just going in parallel to the line?
>> I would say in the case we will go like this. Yeah, I would say like like that rather parallel to the line because it looks similar >> if we're going parallel.
>> I agree. Yeah. So So we have a start transtory.
>> Yep.
>> Great. Transtory.
>> Where do I put our paperwork?
>> It's okay. underneath. We hide it underneath.
>> Is there this sponge coming up?
Julio, sorry. But is there this sponge that whose name I forgot?
So at each uh end and start of the transect we diligently we write down the coordinates and the depths um >> to keep track of I think that's Okay.
>> Oh, jelly to the left.
>> Mhm.
>> Or Yeah.
>> Jellyfish.
And we're moving onward on this yet unexplored uh deep seabed field, a volcanic area.
So this area has been mapped before. So we know the topography, but no no one has ever visually captured this before. I've been down here with a camera.
Yeah, was a little bit of blue. We were on the top of a little mountain.
>> Mhm.
>> We won't see anything for a while.
Maybe.
>> Yeah.
>> Why? Because there was a gap.
>> Yes. So, we're currently at about two 2,6 m deep.
on top of a of a hill. And so we're moving a bit until we can see seabed again like >> Yeah, hold on because we have to fit something with the with the cable >> Okay, don't worry. There she put a lot of concentration.
I just tucked a little bit because we have some gap here on the on the drum.
Do we need to pay out a little bit and learn from the piece so we can do it so it's even?
>> Okay.
>> Yeah. On the ship here we have a big drum of a very very long cable of 4,000 m. I think 4,000 m of cable on a drum.
Um, and we have to make sure that there's not a big cable salad. Do you say that in English? Do you think? Do you say that in Spanish? A cable salad.
>> Salad.
>> A salad of cables. So when all your cables are really messed up, we saw it's cable salad. I don't know if we have an expression for that.
>> I've never heard that in English. I think >> only so we want to avoid uh that from happening. So >> cable.
>> Yes. So we're fiddling here. how you say it in German.
>> A cab salad.
>> Cabbell salad.
>> Yes.
>> So it's actually very similar to the English word at the same time.
>> Makes sense.
>> Yeah.
>> When I was a child, that would was actually a big thing because you have we had these cassettes for audio books, music or so. And when something was wrong with the cassette recorder, it could create a big cable salad and then your your cassette was mixed messed up and you needed >> Do you remember that as well? You needed to roll that. But you didn't have a name for the mess created.
>> No, >> not that I'm aware of. Uh on Leo on Leo the Leo there.
>> He never knew if your cassette worked afterwards or not. So it was too badly injured.
>> Yeah.
>> But yeah, let's move back to the seabed.
>> Just cut down 30 m.
>> Okay.
>> Okay. All stopped.
>> No, no, keep going.
>> So they need to fit something steady.
Yeah, if you need >> Yeah, we see on the soft sediment that there are some >> little bulbs, little mounds. Um, we don't really see what is living in the sediment on the sediment here, but we know that there's more life >> in there, even though it doesn't look that spectacular, at least to me. Um, yeah. And we're moving on to find more rocky areas with more sponges. And hello little jellyfish.
>> Oh, it's making little spins for us.
I'm telling you.
>> Yeah.
She be cruy. Keep me.
And we have some more. Oh, no, not holes, but probably these little stalked animals. Yeah.
Yeah.
>> Yeah.
>> Yeah. I wonder what are those.
>> But all of first glance I sometimes think it's like a hole because of the shading, but then now it's also the stock animal.
>> I mean, it could be many things there. lost.
>> There you can really see how much sediment is on those rocks and that there are really rocks underneath here, >> but very well hidden.
>> Of course, we're on a valley behind the rift.
>> So all the sediment, >> all the sediment end up here. Yeah. Ages and ages of of sediment falling, burning the snow.
>> Yeah.
like a snowy landscape around here.
>> Yeah, >> you see >> small ones. Yes, we have smaller compata.
What's that?
>> The the black thing.
>> That's a rock thing. Yeah, that's just a rock.
That's probably the rock beneath >> just taking one There a lot of these of the little jellies.
Oh, it's the same one following us.
Maybe we can speed up a little bit.
>> Yeah, we've got just all sand in front of us at the moment.
>> All sand.
>> It's It's just sand, right? So, yeah, we can speed up >> if that's No problem. We're going to speed up a little bit.
>> Not want to seem to block the jellyfish.
>> Okay.
>> And let's see how they look like.
>> Going to speed up because there's more >> sand sandy bottom coming up in front of us.
>> Now it's more interested in the rocky areas >> to Yeah. see more of the sponges and other other organisms.
Maybe you can come inside. Hello.
>> Okay.
>> So now we are a little bit faster because it's kind of sedimentary with everything repeating and repeating. So >> but later there's more of rift surface coming up. In about 30 m we have a >> interesting outcrop.
>> Bridge.
>> Can we change the area slowly? North please. Still the same speed continuously.
>> So here we have moved our lava box.
Oh, tennophora. Nice and sparkly.
Oh, hey.
So, we can see the the kums the little kums on it uh that are sparkling. that made a sense >> but we don't see it anymore and I will lock it and as I learned before uh these uh this jelly and the sponges have a fight going on right >> well in the scientific community um there is this conversation going on about who is older if tenophora or sponges um and there is every once in a while a paper published saying that it's tenophora or sponges. Uh I'm not following this day by day. So I think that now uh sponges are winning for now until new evidence uh for 10our sponges. So but it's interesting. I would say that the sponges um that makes more sense that the sponges are older because uh the the way they are shaped uh so it's more easy to me uh the evolution to produce sponge than to produce a tenophora tenophora they have symmetry um the tissues are a little bit more uh specialized uh but yeah it's it's an interesting uh debate and conversation or fight if you want >> and if we're talking about the time spans of of age. It's like they are 600 million years or something old.
>> It's also a debate. I mean the the the oldest fossils that we know for sponges are uh at the at the Cambrian around 540 million years ago. But then we have evidence that the sponges can uh can be found in all the rocks. Uh just that we don't have the fossils. we have chemical um molecules that we found on rocks that are very old. Uh and in those rocks we find we find the same chemicals that are only produced by sponges. Um so this is one evidence uh that sponges are actually older than 540 million years ago. Uh yeah, those are steriles. the the molecules that are telling us that probably sponges appear way uh before than um the the fossil record is telling us back to 600 or even older 600 million years or even Yeah. Unimaginable time scales.
>> Mhm.
>> Far before any dinosaurs, before trees, before Yeah. any other animal.
Those cracks.
Is that >> the migalia?
>> Falarma. Yeah.
>> Falama.
>> We haven't seen the other asanima species at all at this depth >> because we are too deep. Yeah.
>> So they are known to be >> see four.
here. Hammering the floor.
>> Say it again.
>> We're going down. That's going down.
Going over the crack.
>> If you look here, >> this is underneath us.
>> Yeah, >> we're looking down.
>> Okay.
>> So, it's a big crack. Big crack. Yeah.
>> Is that Is that problematic for you?
>> I'm trying to look down. So, I was telling you if you look with your eyes on that, see?
>> Yeah.
Next to the camera that we uh have mainly in the screen in front of us, the ROV also has other cameras for navigation all around to be able to see what's below, what's above, what's at the sides, and um to to ease navigation, but also it's interesting sometimes to see, oh, what's what's actually at the moment underneath us or what's next to us or above, etc. So we sometimes have to be uh yeah looking >> to the other screens as well.
>> Yep.
>> Oh no. I put the numbers on the keyboard again.
Is there coming up?
>> I don't think so. I think the psychalitis.
>> What?
>> It has a stem. No.
>> Yeah, with a stem. That's the largest.
>> We've seen a couple of those.
>> What are they called again?
>> Sakalits, I think.
>> Yeah, we want to double you want to double check that.
>> Okay.
>> Yeah, that one. Sakal.
>> Sakalix.
And they also probably have a stem so that they can bit better filter.
>> Exactly. Those are the strategies to sedimentary areas >> and not get so much sediment in their >> pores.
But now for say because we're going above them, we're stirring up a little sediment, they can easily expulse that again. So it's not like really bad there. Is there still fish?
>> Yeah, it's a fish.
>> Yeah, it would be more problematic.
>> Carnival sponges there.
>> Uh, no. Where's the carnival sponge?
>> Oh, no. It was if I was alive. Sorry.
>> Yeah, that was a trick question here.
H not with me.
Ah, >> but there we have some sponges.
>> Yeah, >> the stem sponges again.
>> Is it the psychoalics?
>> Yes.
Yes.
>> Seems good.
Heat.
Heat.
Change the bearing again.
>> Can we change the bearing slowly again to 045, please?
>> 045.
Thank you.
We're >> already getting closer to the end of time.
>> Yeah.
>> Have the transets here.
>> No, you there's plenty of central pallets. So, there's another one over there. Yep. I already check it for the next one.
>> It will be the last one in this area.
>> Mhm. But we have um >> uh where do we have the overview?
>> I don't know.
>> We have another >> Yeah, sorry. I was not thinking.
>> No, it was it was correct. one.
>> Yeah, it was these three. But then we have another few coming up where we where we could do a blue transit, but it would take quite a while.
>> So now we don't have another one. Yeah, we need to do transiting.
>> Um, but it would be a few kilometers. So I think we need to check if we indeed want to do that or not. Um, yes.
Maybe I can check.
>> Can we follow the the rest?
>> Yeah.
>> Uh, your current is going to just start everything up. You have really bad viz going across that.
>> Is that what you want to do?
>> Well, we want to get to the point, but maybe instead of going in >> Yeah, we just want to have bad video.
>> It's not going to go well in that direction because of the current.
>> Okay. Okay. Yeah, that's fine. That's fine.
to the point.
>> Yeah. No, it's fine. Yeah. So, we should check if we because we end this transact here normally how I go about with um with the next transact that we plan.
Shall I go up and check with them?
>> You still have some um meters to to go, but yeah, you can you can go and ask.
Maybe you think they're going to come back.
>> Sorry.
>> They're debating if they're going to come back.
>> Sandra come back. Where >> she going to come back? Tell us.
>> Oh, they're already discussing. Good.
>> Thanks.
>> So, we can just hang out a bit. So, yeah.
No way to collect that one.
>> I I asked just in case.
>> Yeah. We would like to collect these sponges called Lisodender complicata because um we try to find out more about their community structure, their connectivity. So how they're connected between different locations also from their genetics, right?
>> So yeah, genetic connectivity is important because then you know how connected they are and how resilient they are. Uh so if you have a population that is very isolated then that rings a bell. Uh the more connected they are the more resilient they are to whatever is happening u to whatever disturbance may happen.
>> I'm jealous.
>> And videape change in 10 minutes. 10 minutes.
>> Yeah. That that was uh aerosopherus.
Yeah.
And this community is just repeating and repeat and repeating. So >> yeah, >> I wonder how many species are there.
>> Mhm.
>> Yeah. I would say that maybe 20 >> 20 of the like the little dots there.
>> Something like that. Something like that.
>> And none of them is described yet. Like potentially >> I don't know.
>> Yeah, we don't we don't know. I'm always just potentially speaking or what we what we expect at the moment.
>> We ring a bell in one because it's a genus that there are not so many species and they are usually shallow water. So that rings a bell and that's why we say that probably it's a new species. That's the standard. But for the rest, there may be of course many new species, but it's a little bit more tricky if you have a group that that has so many species. You have to check all of them.
>> Okay.
>> Uh just to know what is what you have.
So that's time consuming. It's not something you can do it uh so quickly and often you have to go to the museums and compare to the material that has been previously collected. Uh sometimes you even have to sequence that material and compare with your sequences of your new material. Uh and this is a process that can can take uh years.
>> But yeah, we will >> we will work on that.
>> Also small is also >> that's the one I want. That's the one I want.
That's >> Is that >> Yeah, that's the one I was trying to collect before.
>> The jealous.
>> No, no, no, no, no. This I don't know what it is.
>> Oo, >> this I don't know what it is.
>> Come up to stir the too much and let that settle.
>> It's just going to hang in so you get a better view of it. Okay, >> just going to bridge for one second.
Okay, so don't think you're going to get it.
See how it's drifted over?
Do you see how it's drifted right over where you want to go?
>> Okay. Okay.
>> Well, we're 7 m 6 m up.
>> So now now you're trying to see what's going on with the with the cloud.
>> Yeah.
See going that way, but it >> seems that the current goes the current's coming from behind us. Uh-huh.
So, as we disturb it, we're going faster than what that is. As soon as we stop, that comes faster.
>> Catches us.
>> Yeah.
So we're discussing at the moment >> current the current is also doing to >> our visibility and the sediment and how we move because at the moment behind >> it comes from behind the current >> it flows past us from behind and >> yeah we might reconsider the bearing.
Yeah, I guess that the the reason why there's so m so much mat is because there's no power >> basically though it's soft.
>> Yeah, I said if we're coming down if we go north to south the current is going south to north. That's the perfect combination.
>> Yeah, >> but we're not.
>> Yeah, >> we're going north. So is the current.
>> We have the wind from the day.
>> Yeah. So we are running out of multih now it's moving really >> completely into the unknown. How exciting.
>> Yeah.
>> Our map of symmetry data is also ending.
So um >> if we if we move further in this direction so we wouldn't have a clue anymore about the topography of the seabed >> two days ago >> which would be very adventurous. Super >> because normally you always you want to have an indication about >> what is the profile like where are you heading because with the ROV we're mostly >> uh trying to go up slope >> and not for example down slope >> and to not disturb any equipment. We try to be >> always cautious of what's coming next.
>> Okay, >> that's manual. Okay.
>> Okay. I'm just collecting now paying in because the we are now stopped. The ship is coming.
>> Oh, and tape change in 5 minutes. I'm reminded here.
>> So, tape change means um that the recording of the video cartridge um will end in 5 minutes because uh we have set 2our tapes. So after every 2 hours we do a backup of the video that we have recorded. So in case there would be um an error, corrupted file, we wouldn't lose too much of it. So we always have like a safety net so never more than 2 hours tape can be lost. And um it's also a way of like switching around here a little bit and um yeah bringing some some shift changes.
What a what a nice transition. Here is an Helena ready to take over soon.
>> How are you doing?
>> Oh good. Just come from lunch.
>> You can look forward.
>> How was lunch or dinner? Actually, if we went by >> our timing, >> our timing, >> it was good. It's always good food on board here. It's wonderful, right?
>> We are lucky indeed.
>> Yeah, we're we're being served very well.
>> Have you made any samples?
>> No, we have not sampling. Yeah. without creating.
>> Did you do like we tried to do to sample the earth?
>> Sample the earth.
>> No, we didn't get that far.
>> Actually, we got the wrong. Yeah.
>> Yeah, true. We did some >> but it's impossible. I was trying to face the current but >> and now I'm not sure what if you are standing by waiting for Sandra's instructions because this is free instruction.
So are we and yeah we're now really going into the unknown.
>> Yes, we followed the um the second transite parallel to our usual line and um then we went upwards and went also a little bit yeah also parallel to that line and discovered uh more of those areas. And we've also seen a lot of these communities of potentially unknown um sponges.
So it was quite hard to always see them and not be able to collect them.
>> Yeah.
2 minutes.
>> Yes.
>> Yes. 2 minutes and then we'll change the tape and then we'll make a backup recording.
>> Uh a backup of the recording.
>> Yeah.
reference.
>> And for the sample you have taken where you went quite into a bit into the unknown, you we've seen that you've collected a rock, but we're not sure yet on the rock. What is on the rock?
>> No, it was invisible. So that is Yes. We sometimes we need a surprise.
>> Yeah.
Video in one minute.
>> Yes. On the other side.
>> Oh, thanks.
>> Yeah. You know, if you don't go for the unknown, then you will never learn new things.
>> Yeah, that's the spirit.
>> Exploration instead of always exploration.
Okay, just on your way to the next >> 28 seconds.
>> So, waiting for >> I will just write end of the transit, right? We agree on that. Yeah. Okay. So, 1156 55.
>> So, this is >> Yeah. So, like >> we're in.
>> All right.
>> 600 mm.
>> Change the tape now.
>> Oh, yes. Can we change the tape?
>> Yeah.
>> Stop recording.
>> Okay.
>> Just passive.
>> Stop. Yeah. Yeah.
Steps allow us to compare like a shallower versus deeper adaptation.
We got a sink.
>> Yeah, that's so light.
No problem.
Once we set up again just like it would be nice to test that is on my mind.
Yeah, >> I can imagine that.
>> Okay, see you.
>> Go to record again. your lunch.
>> We have two formats this one. Yeah.
So, we're um putting a new cartridge in there now and also indicating in our locking system that we changed the tape.
So, we will know afterwards what is on which tape and when was it changed.
Did you are we recording again?
>> Are we recording again as the tape chang?
>> Okay.
>> Yes.
>> Are you ready?
>> I'm ready. Yes.
>> Two. Three.
>> Thank you.
>> Uh, yes. And start recording again.
Thanks.
>> All right. Thanks a lot. enjoy lunch or dinner.
And here's the Oh, yes. I will take that for So, this is um An Helena and Sergi being back after a little bit of break and Yes.
>> And we will continue. Ooh, there is a crack of some sort.
>> So, who knows what that is.
>> But it's it's an exciting little crack there.
So, I'm back.
>> Yes.
>> So, did you have a good break, Sergey?
>> Yeah.
>> Yeah.
>> I have cleaned the lab.
>> Long enough. It's fine.
>> Yeah. I spent the time cleaning up in the lab.
So of course when a s when um when an RV dive comes the ROV come back to the surface if you have sampled a lot or some at all >> when it comes up we have to preserve those samples and make sure that they are being taken care of so that we can spend use use them well. And so we have spent most of the time since last evening preserving the samples we got up.
>> Yeah, >> it's not just pouring them into something. You have to make sure that you are sorting through all the different little milllers of water to check if there is something in the water and to make sure that we note all the details about where they come from.
So it takes a lot of time to >> and then get them into the right fixitative right >> for the different purposes.
>> Yes.
>> Yeah. So everything that is been uh taken as a sample, it's being used uh on deck and we are three people in the sponge team, three people in the station team and they're like a fully devoted to preserve on time because it needs to be done as quickly as possible, >> especially if you want to look at the DNA.
So, um >> I got up at 2:00 in the morning to start sorting samples.
>> Mhm.
>> That's what uh we are here for, right?
>> Yeah. That's why we do that's why we have shifts.
>> So, there's always somebody awake to to work on whatever is needed to work on.
I think these cracks are interesting.
>> Let's just have a look. Oh, still a little bit dirty.
because we're still in a very soft sedimented area.
>> Yeah.
>> And then we have these cracks.
>> Yeah. Cannot see. Well, here >> it's a little bit >> It's a little bit sandstorm.
>> Yeah. Again, >> we thought we got rid of this, but >> we're going to start moving >> new location. Sure. So we will have a a blue transit >> a little bit.
>> Yes, we are moving to a new transect and we will lift off a little bit of the seafloor.
>> Um even though it was a nice little crack there. We will um just go a little bit up from the seafloor so that we can move without swimming around flying around in a sand cloud.
And so we have a new >> okay troops >> location >> that's this D finished we 3 km to the next station >> and this too much so they're saying they we recover the surface >> okay >> so we changed that we go end of the dive and we will go to the surface now and that was a very quick time in the sh for us >> I will just make sure before we come off >> we will we will hang out a little bit here British >> start.
>> Can we stop the movement, please?
>> Start with the finishing of this um >> of this dive.
>> Yeah.
>> And I am sure we're going to get to new live streams soon.
>> So, uh follow from both the international landing page or on social media to find out when we are on again.
This of course always depends a little bit about weather and how long the time takes to go to the next place we will dive and the decisions that are being made uh here on board with the captain and the uh leader for the team and the leaders for the expedition and where we're going next.
So, while we're waiting to go up, we can look at this strange crack down on at the right hand corner.
It's kind of cool, huh?
