Meereswissenschaftliche Berichte No 56 2003 - Marine Science Reports No 56 2003 ... : In the frame of the HELCOM monitoring, data on species composition and biomass or abundance of phyto- and zooplankton as well as macrozoobenthos from the western part of the Baltic Sea to the Eastern Gotland Sea (Fig. 1) were gathered in 2002 and discussed in comparison with satelliteand ship-based physico-chemical data. Information on sedimented material (from 2001) is also given. Comparisons with previous years were made and trends were checked. Data from the five regular monitoring cruises were complemented by data gathered from additional phytoplankton samples taken by Landesamt für Natur und Umwelt of the German country Schleswig-Holstein and from monitoring cruises of the National Environmental Research Institute Roskilde (Dänemark).
