The importance of prey aggregations to the distribution of Brunnich's guillemots in Storfjorden, Svalbard

Most guillemots (Uria lomvia) foraged on the west side of the fjord, coincident with a weak subsurface front between warm Atlantic water, which penetrated Storfjorden from the south, and cold Arctic water. Food samples from the guillemots contained primarily crustaceans (Parathemisto spp. and Thysan...

Description
Summary:Most guillemots (Uria lomvia) foraged on the west side of the fjord, coincident with a weak subsurface front between warm Atlantic water, which penetrated Storfjorden from the south, and cold Arctic water. Food samples from the guillemots contained primarily crustaceans (Parathemisto spp. and Thysanoessa inermis) and polar cod (Boreogadus saida). Foraging guillemots were strongly correlated with aggregated prey but showed no significant correlations with physical properties of the water column.
