Environmental control and potential fate of size-fractionated phytoplankton production in the Greenland Sea (75
Environmental control and potential fate of phytoplankton production were investigated in the Greenland Sea (75 degree N) in June 1989. Phytoplankton biomass, taxonomic composition and production were size fractionated. Total primary production was generally high (up to > 0.9 g C m super(-2) d su...
