Walrus areas of use in the Chukchi Sea during sparse sea ice cover

Chadwick V Jay, Anthony S Fischbach & A.A. Kochnev
The Pacific walrus (Odobenus rosmarus divergens) feeds on benthic invertebrates on the continental shelf of the Chukchi and Bering seas and rests on sea ice between foraging trips. With climate warming, ice-free periods in the Chukchi Sea have increased and are projected to increase in frequency and duration.
