Winter Distribution of Ringed Seals ( Phoca hispida ) in the Barrow Strait Area, Northwest Territories, Determined by Underwater Vocalizations
In order to assess underice distribution of ringed seals (Phoca hispida) in winter, we made recordings from 23 to 30 April 1982 at 32 sites chosen to represent different habitats in the High Arctic. By regressing the vocalization rate at each site against variables for habitat quality, we found that...
