Marine Ecosystem - Barents Sea |
|||||||||||||||||||||||||||||||||||
Overview | Bering Sea | Barents Sea | Greenland See the annually updated Arctic Report Card The Barents Sea is the continental shelf north of the Scandinavian peninsula. Cod stocks in the Barents Sea are influenced both by fishing and by climate. The production or recruitment of cod (bars in top figure, below), is thought to be related to the flow of warm water into the Barents sea from the North Atlantic Ocean. A recruitment increase occurred in the mid-1970s and 1990s, when there were warm ocean temperatures north of Scandinavia (the Kola Peninsula), shown by the red curve in the middle figure below. Capelin are a food source for cod and whales. Capelin biomass shows large variability over the last twenty-five years. Herring shows changes on decadal scales, reflecting both climate and fishing impacts.
