Distribution of the copepodite stages of Calanus finmarchicus from Lofoten to the Barents Sea in July 1989
The zooplankton biomass in the Barents Sea can vary by an order of magnitude from year to year. One reason for the large change is the varying transport of Calanus finmarchicus from the Norwegian Sea into the Barents Sea. How much of the population is stationary in the Barents Sea and how much is tr...

The zooplankton biomass in the Barents Sea can vary by an order of magnitude from year to year. One reason for the large change is the varying transport of Calanus finmarchicus from the Norwegian Sea into the Barents Sea. How much of the population is stationary in the Barents Sea and how much is transported from the Norwegian Sea is unknown. Zooplankton samples were collected along the coast of North Norway from Lofoten and into the Barents Sea during the early juvenile fish survey in July 1989.
