Ziel der Reise / Objectives of Cruise:

The cruise was conducted within the framework of GLOBEC Germany "Trophic interactions between zooplankton and fish under the influence of physical processes". Investigations were carried out in the Central Baltic Sea with its two major basins, the Arkona and Bornholm Basin. Research focused on adult and juvenile (0-group) Baltic sprat and cod. Concurrently, plankton hauls (Bongo) were conducted to check for the potential occurrence of larval or juvenile stages of sprat or cod, and hydrographical measurements were carried out on stations selected from the GLOBEC station grid in the Bornholm Basin. This last GLOBEC-Germany field survey has successfully collected data on abundance and horizontal and vertical distribution of sprat ' particularly 0-group individuals ' in the Central Baltic Sea late in the year. In the Arkona Basin, the program could be completed as planned, whereas adverse weather conditions erforced some cuts on the intended program in the Bornholm Basin. 0-group sprat were particularly abundant in trawls in the southern parts of both basins. Given the time of the year, Bongo hauls (335 ?m and 500 ?m nets) contained a remarkable number of larval and juvenile stages of Baltic sprat (~50) and cod (~70).
