Use of the Beaufort Sea by King Eiders Breeding on the North Slope of Alaska
Abstract: We estimated areas used by king eiders ( Somateria spectabilis ) in the Alaskan Beaufort Sea, how distributions of used areas varied, and characteristics that explained variation in the number of days spent at sea, to provide regulatory agencies with baseline data needed to minimize impact...
