The distribution and diel movements of Brünnich's guillemot Uria lomvia in ice covered waters in the Barents Sea, February/March 1987
The distribution of Brünnich's guillemot in ice covered waters and near the marginal ice zone in the southern part of the Barents Sea was mapped from ship and helicopter in February/March 1987. High densities of Brünnich's guillemot (up to 1,300 ind./km2) were found in ice leads. The densi...
