[00:00:00]This sound was recorded deep in the Pacific Ocean in 1997.

[00:00:14]Scientists had never heard anything like it.

[00:00:17]The sound was so powerful, it was detected by underwater microphones more than 5,000 km apart.

[00:00:24]NOAA picked it up using a network of hydrophones originally built during the Cold War to track Soviet submarines.

[00:00:32]And when researchers slowed the audio down, it sounded almost biological.

[00:00:37]The source came from a remote part of the South Pacific, 50° south, 100° west.

[00:00:44]No submarine, no earthquake, or animal matched it.

[00:00:48]Some people believed it came from a creature larger than a blue whale. So, the internet called it the bloop.

[00:00:56]But years later, scientists finally found the real explanation.

[00:01:01]The sound matched something called an icequake, a massive fracture inside Antarctic ice shelves.

[00:01:08]The bloop wasn't a sea monster. It was an iceberg the size of a small country tearing itself apart in the ocean. And honestly, that might be even scarier.
