Ziel der Reise / Objectives of Cruise:

Physical, chemical, biological resarch and fishery oceanography This multidisciplinary cruise was conducted within the framework of different projects, i) EUROCEANS and ii) GLOBEC Germany 'Trophic interaction between zooplankton and fish under the influence of physical processes' The different research activities were focussed on the Bornholm Basin. Additionally CTD stations in the Arkona Basin were conducted. The survey considered investigations on different plankton distributions, incl. phyto-, zoo- and ichthyplankton as well as on pelagic clupeid and gadoid fish. The physical measurements of this cruise were designed to investigate the quasi-synoptic three-dimensional distribution of temperature, salinity and oxygen. Within the framework of the aforementioned projects the data will be utilized to initialize a three-dimensional baroclinic eddy-resolving circulation model of the Baltic Sea. Other major goals were the description of abundance, biomass,production and nutritional condition of phyto-, zoo- and ichthyoplankton. Further emphasis was given on the meso- to small-scale horizontal distribution of their main predator fish species herring and sprat. Further, stock structure, gonadal maturation, egg production and survival of sprat and cod was investigated.
