Scientists in April placed cameras on four females roaming Beaufort Sea ice north of Alaska's Prudhoe Bay.
The cameras are part of a study led by research biologist Anthony Pagano to understand how polar bears respond to loss of sea ice from climate warming.
The clip shows a bear entering the icy ocean waters, trying to eat a frozen seal and interacting with a male.
Pagano says in a release the information will help scientists understand the bears' nutritional demands and energy expenditure in the context of less sea ice.
