520 3# ‡aEstimates the role of biology in the vertical flux of carbon in the central Greenland Sea from 1993 to 1995. The annual phytoplankton bloom began in May and reached peak proportions in June. In June 1994, the initiation of the bloom was in the central Greenland Sea, and the patchy distribution of prymnesiophytes and diatoms appeared to be regulated by silicate. By August, the surface was depleted of nitrate, and chlorophyll-a concentrations were significantly reduced relative to bloom levels. Thus, the phytoplankton bloom peaked and senesced before August. The growth of zooplankton stocks appeared to respond quickly to available phytoplanktonic food supply, a pattern which also was shown by bacterial biomass. The annual vertical flux of particulate organic carbon was measured with sediment traps. Sedimentation of the spring phytoplankton bloom commenced in June and rates decreased rapidly with depth, indicating that a major part of the spring phytoplankton biomass is consumed, oxidised and regenerated by the food web during its descent. In the autumn, an allochthonous source dominated sinking particles in the central Greenland gyre resulting in an annual peak in sedimentation at all depths. Suggests that the biological carbon pump in the Greenland Sea is regulated strongly by production and subsequent downwelling of dissolved organic carbon, sedimentation of particle-bound carbon in dissolved and particulate forms, as well as respiration of overwintering zooplankton stocks.
