Elephant Seal Tagging

Season 1 Episode 3 | 2m 45s

Elephant seals act as living submarines, diving as deep as 5,500 feet and staying under the ice for up to 90 minutes. Seals are tagged to create a record of the increasing seawater temperature. The sedated seal is fitted with miniature oceanographic sensors. They’ll record the location, depth and water temperature whenever the seal dives
