Pacific walrus group hauled-out on sea ice in the Chukchi Sea. The photo was captured during a survey of the age structure of the population to evaluate population status. Observers assign each animal in a group to an age/sex category according to published criteria. USFWS Permit No. 33776D.

Arctic marine ecosystems are undergoing rapid physical and biological change associated with climate warming and loss of sea ice. Sea ice loss will impact many species through altered spatial and temporal availability of resources. In the Bering and Chukchi Seas, the Pacific walrus Odobenus rosmarus divergens is one species that could be impacted by rapid environmental change, and thus, population
