Plankton samples and oceanographic data were obtained during transect studies across fishing banks over the Southwest Greenland shelf in June 1999, May, and July 2000. The study gives a detailed description of micro- and mesozooplankton distributions and community structures during spring bloom and post bloom periods. Plankton distributions were related to the physical environment described by a hydrodynamic ocean circulation model. More than 30 species and a larger number of taxonomic categories were identified in the zooplankton samples. Large copepodites of Calanus finmarchicus, C. glacialis and C. hyperboreus generally dominated the micro- and mesozooplankton biomass, with Pseudocalanus spp., Metridia longa, and Oithona spp. comprising most of the remaining biomass. By number, bivalves larvae and relatively large copepod nauplii (>200µm) dominated the zooplankton community (>50µm) in May, whereas smaller copepod nauplii (<200µm) were dominating in June and July. In May during a spring bloom period, diatoms, Thalassiosira spp. and Chaetoceros spp., generally dominated
