Zooplankton distribution and feeding in the Arctic Ocean during a Phaeocystis pouchetii bloom
In early summer 2007 we determined the vertical distribution of mesozooplankton (>200 μm) and assessed the copepod feeding rates in 19 stations distributed along the East Greenland Current and the Fram Strait. The study coincided with a bloom of the haptophyte Phaeocystis pouchetii in the colonia...
