The Kongsfjorden pelagic ecosystem is influenced by both Atlantic and Arctic waters. The relative amount of the Atlantic Calanus finmarchicus<\/em> and the Arctic Calanus glacialis<\/em> varies yearly. Calanus finmarchicus<\/em> has been the dominant species for the last decade, due to increased inflow of Atlantic water and increased temperature. Changes in the zooplankton community will cascade to higher trophic levels, and might change the character of the pelagic ecosystem. Therefore, the composition of the zooplankton community in Kongsfjorden might function as a climate indicator on a local scale.<\/p>\n\n\n\n
