Hydrographic features, cetaceans and the foraging of thick-billed murres and other marine birds in the northwestern Barents Sea
The at-sea distribution of thick-billed murres (Uria lomvia) in southeastern Svalbard waters was studied during the summers of 1992, 1993, and 1996. The Storfjordrenna region south of Svalbard was confirmed as an important foraging area for thick-billed murres; murre aggregations were located at dis...
