  • Study of spatial and temporal variations of hydrographic, hydrochemical and biological parameters in the frame of the COMBINE Programme of HELCOM , combined with long term observations of IOW

  • Monitoring cruise with respect to topic assessment and long-term changes of marine physical, chemical, and biological variables in German coastal waters and in the offshore regions of the Baltic proper.

  • Marine meteorological,hydrographic,chemical and biological investigations according to the Baltic Monitoring Programme (BMP) of HELCOM.

  • Study of spatial and temporal variations of hydrographic, hydrochemical and biological parameters in the frame of the COMBINE Programme of HELCOM , combined with long term observations of IOW

  • Termin-Fahrt

  • This cruise is the fourth in sequence for "Seasonal dynamics of fish larvae and some hydrographical parameters in the northern Portuguese upwelling area" and also the fourth in a partly different sequence for "Eastern boundary currents in the temperate Northeast Atlantic".

  • The objectives of the cruise were 1) to test a profiling mooring in the Gotland Basin, 2) to measure elemental mercury and CO2 in surface waters along track, 3) to obtain samples for a method comparison for pH measurements, 4) to measure denitrification rates in anoxic waters, 5) to recover a sediment trap mooring from the Angermanälven (Sweden), 6) to isolate microorganisms from the Baltic Sea with the ability to degrade oil an pharmaceuticals. We left Rostock on the 18. July heading for the Gotland Basin. On arrival the winds and waves were too high for any station work so we continued the voyage north to Angermanaelven. We arrived at the mooring site on 21. July at 13:00 UTC. After recovery of the sediment trap mooring we made our way south back to the Gotland Basin. On the way it became clear that the weather conditions wouldn't allow work in the central Gotland Basin and we anchored close to land off Gotland to wait for improving weather (22. July at 21:00 UTC). On the 23. July at 21:00 UTC we lifted anchor and progressed to the GODESS mooring position, where we arrived on the 24. July at 04:00 UTC. After two CTD profiles the profiling mooring GODESS was deployed, followed by a series of CTD casts and one pump-CTD cast to provide water samples for incubations and lab analysis. Finally the GODESS mooring was recovered and we continued to the FINO2 station where an ADCP mooring was deployed (25. July 16:30 UTC). From the FINO2 we made our way back to Rostock where the vessel was moored at 06:00 UTC on the 26. July.
