Walrus Monthly Foraging Utilization Distribution in the Chukchi Sea: 2008-2011 [Jay]
This dataset describes Pacific walrus (Odobenus rosmarus divergens) utilization of the Chukchi sea by tracking walruses and their hourly foraging behavior from June through November using satellite-linked tags during years of sparse sea ice (2008-2011). To estimate the density of walrus foraging on...
