  • The cruise EMB099 was carried out as a joined cruise of the environmental monitoring program of the Federal Maritime and Hydrographic Agency (BSH) and the Baltic Sea long term observation program of the Leibniz-Institute for Baltic Sea Research Warnemünde (IOW). It was the second cruise in a series of five expeditions performed annually. The data acquired are used for the regular national and international assessments of the state of the Baltic Sea, and provide the scientific basis for measures to be taken for the protection of the ecosystem Baltic Sea. The cruise was performed in appropriate weather conditions. All planned research activities were realised.

  • Hydrographic, hydrochemical and biological monitoring of the Baltic sea. Standard measurements with respect to the Baltic Monitoring Programme (BMP) of the Helsinki Baltic Marine Environment Protection Commission ‑ HELCOM and IOWs long term observation programme. Pilote measurements for the investigation of gas dynamics in surface waters. Standard CTD measurements and water sampling, plankton sampling with plankton net, benthos sampling by grabbing and dredging, underway measurements of surface water properties, standard meteorological measurements.

  • The overall objective of cruise M117 is to investigate biochemical processes in upwelling zones. Upwelled water is characterized by re-mineralized nutrients, CO2-saturation, cold temperature and enhanced primary productivity. The phenomenon of upwelling is of interest to several research activities at IOW, and, therefore, proposing a common cruise is an efficient approach to understand potentially interconnected biochemical processes within upwelling systems of the Baltic Sea. Proposed research activities include (1) phosphorus availability for harmful cyanobacteria blooms, (2) air-sea CO2 exchange, (3) marine aerosol formation, (4) formation and transport of organic mercury species, and (5) energy turnover of zooplankton communities along food quality gradients. The research activities rely on supplementary data of nutrients and phytoplankton composition, and, therefore, we propose to combine the activities with a monitoring program. IOW is conducting long-term observations in the Baltic Sea and on behalf of the Federal Maritime and Hydrography Agency (BSH), IOW the German part of the environmental monitoring program of the Helsinki Commission (HELCOM).

  • Program included geological, chemical, physical and biological measurments in the German Baltic Sea EEZ. Benthic Chamber experiments and measurements for sediment / water exchange of solutes and gases on the 4 key SECOS stations with different types (mud and sand) of sediment along the German Baltic coast was done, also covering the seasonal variability by complementing the previous sampling campaigns. By sampling the sediment (Multicorer, van Veen grab, dredge, Benthic Chamber) and the parameters of the water column above (CTD, moorings: Bodengestell Aquadopp 600, Bodengestell ADV plus 1200 kHz ADCP, anchor mooring chains) in particular the matter and gas flows were studied in the boundary layer. Numerous turbulence microstructure measurements were carried out. Chlorophyll content in sediments was sampled for quantification of bioturbation activity. In the second part of the cruise the development of saltwater intrusion was investigated on the transect of standard monitoring station up to the Gotland Basin. At each station CTD profiling was carried out; oxygen, nutrients and gas samples from characteristic horizons of the water column, as well as benthic samples for macrofauna by means of van Veen grab and for Chlorophyll content in sediments by means of Multicorer were taken at exemplary stations.

  • The objectives of the cruise P485 from Malaga to Ponta Delgada in May 2015 on board R/V Poseidon were: 1) to investigate the water column properties along three meridional transects (23°W-22°W-21°W between 31°N and 37°N) in order to localize the Azores Front and to understand the changes in biogeochemical properties. 2) to perfome extensive trials of the SMIS fleet at different depth levels and in deep sea (>5000 m) and 3) to recover the Kiel276-29 mooring.
