In an effort to protect Alaska's pacific walrus population, U.S fish and wildlife scientists are tracking their movements to see how they respond to receding sea ice.

The U.S Geological Survey recently released footage from an August walrus haul out in Point Lay, showing as many as 20,000 walruses moving across the beach.

Experts said it's a normal number, but changing sea ice conditions are making it increasingly difficult for the animals to go into the water and feed before returning to the ice.

By tracking their movements, federal fish and wildlife officials said they're able to share the information with local pilots, hunters and vessel operators and ascertain none of the walruses are hurt or distrubed while they're on shore.
