Ziel der Reise / Objectives of Cruise:

Physical, chemical, biological resarch and fishery oceanography This cruise was carried within the framework of the multidisciplinary research project CODYSSEY 'Cod spatial dynamics and vertical movements in European waters and implications for fishery management'. The different research activities were first focussed on a hydrographic survey in the Arkona Basin. Additionally in the Bornholm Basin, the Stolpe Trench the Gdansk Basin, and in the Gotland Basin the survey also considered investigations on different plankton distributions, incl. zoo- and ichthyplankton as well as on pelagic clupeid and gadoid fish. Fishing activities during the cruise were mainly performed within the Bornholm Basin, the Gdansk Deep and in the southern Gotland Basin. The physical measurements of this cruise were designed to investigate the quasi-synoptic three-dimensional distribution of temperature, salinity and oxygen. According to the work programme of CODYSSEY, the hydrographic data will be utilized to serve as a geolocation database for recovered tagged Baltic cod. Within the framework of this project the data will also be utilized to initialize the three-dimensional baroclinic eddy-resolving circulation model of the Baltic Sea used for as a data base for the geolocation of the tagged fish. Other major goals were the description of abundance, biomass,production and nutritional condition of ichthyoplankton. Further emphasis was given on the meso- to small-scale horizontal distribution on herr
