This data release includes two summary geospatial rasters in GeoTIFF format indicating the seasonal Pacific walrus distribution apparent from from ARGOS location tracking obtained from the temporary attachment of ARGOS transmitter tags to Pacific walruses between 1987 and 2015. We deployed tags on walruses at locations in the eastern and northern Bering Sea, the eastern Chukchi Sea, and southern coast of the western Chukchi Sea. We estimated daily locations and characterized seasonal distributions (May-November and December-April) across the Pacific Arctic on a coarse grid (50km resolution).
