🦈 THE RETURN OF WHITE SHARK NORI

Added: 2026-06-03

[00:00:00]White shark Nori has found her way back after an 8-month journey [music] covering more than 4,000 miles of ocean.

[00:00:06]White shark Nori has returned to the exact same corner of Atlantic Canada.

[00:00:11]Nori is an 8-ft 10-in juvenile female tagged off Nova Scotia by researchers from the Tankook Islands Marine Field Station [music] and from Ocearch. After spending the winter in the waters off North and South Carolina, Nori is now returned to Nova Scotia, an important recurring [music] summer and fall foraging habitat for the Western North Atlantic white shark population.

[00:00:32]Nori's May 25th ping placed her off Mahone Bay, Nova Scotia, only about 7 miles from where she was originally tagged last October.

[00:00:41]Exactly how white sharks navigate with such accuracy remains uncertain, but researchers believe they may rely on a combination of the Earth's magnetic fields, [music] water temperature gradients, coastline cues, and learn migratory routes.

[00:00:55]Nori's return to the tagging area suggests a high degree of seasonal site fidelity, or the tendency of for an animal to repeatedly return to the same geographic region over time.

[00:01:06]The waters off Eastern Nova Scotia likely provide reliable food resources, favorable environmental conditions, >> [music] >> or even navigational reference points that are important enough for a shark like Nori to return year after year.

[00:01:19]Repeated returns by our tagged sharks can help researchers identify important foraging corridors, and better predict when white sharks are most likely to use these northern habitats. As white sharks like Nori return to Atlantic Canada, researchers will continue to monitoring the movements through satellite tags, as well as internally implanted acoustic tags detected by underwater listening stations. Together, these tracking technologies are helping scientists better understand white shark migration, habitat use, health, reproduction, and behavior. And ultimately, that knowledge can help support more effective conservation and protection [music] measures for these vital apex predators of the western North Atlantic.
