An Aerial Census of Ringed Seals, Northern Coast of Alaska
Aerial surveys of ringed seals, Phoca (Pusa) hispida Schreber, in areas of land-fast ice extending along the Alaskan coast from Point Lay to Barter Island were made between 8 and 15 June 1970 in order to establish a base line index of density and distribution. Surveys of 8, 9 and 13 June were used f...
