ANCHORAGE, Alaska - The U.S. Geological Survey has released a clip of the first video shot from the neck of a polar bear on Arctic sea ice.

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.
