Horizontal distribution of calanoid copepods in the western Arctic Ocean during the summer of 2008
The horizontal distribution of the epipelagic zooplankton communities in the western Arctic Ocean was studied during August-October 2008. Zooplankton abundance and biomass were higher in the Chukchi Sea, and ranged from 3,000 to 274,000 ind. m^[-2] and 5 to 678 g WM m^[-2], respectively. Copepods we...
