From 1 - 10 / 19
  • Studies of the spatial and temporal variations of hydrographic, hydrochemical and hydrobiological parameters in the frame of the COMBINE Programme of HELCOM

  • Monitoring cruise in the frame of the COMBINE programme of HELCOM

  • Monitoring cruise in the frame work of the Baltic Monitoring Programme of HELCOM. Contribution to the state of the marine environment, incl. trend analyses of hydrographic, chemical and biological parameters in the HELCOM database.

  • The cruise began in Rostock with polish colleges.The sampling concentrated an the inner Bay of Gdansk. Wind was permanently above 4 Beaufort from west to southwest and an March 3. All stations were sampled in the same way; starting with a CTD with attached water bottles, followed by net tows and sediment sampling. Water was routinely taken from the surface, 5m, 10m, 20m and from the bottom near layer. Oxygen, pH and nutrients were analysed immediately onboard. Samples for particulate silica analysis were taken from 5m and bottom waters. I. Bialkowska took samples for iron determination in the Vistula outflow. Filters for POC, PON and Chlorophyll analysis and 1 litre of filtrate were collected in each depth and stored. Later analysis of the stable isotope composition of nitrogen and carbon in nitrate, dissolved CO2 and particles will be performed.

  • Ground truth measurements for ENVISAT-MERIS validation. Measurement of optically active water constituents and their IOP's and investigation of their influence on the spectral reflectance at the sea surface. Measurement of coastal waters distribution using continuous through flow devices.

  • Monitoring cruise in the frame of the COMBINE programme of HELCOM

  • GLOBEC Germany: Instrument, training, measurement & presentation cruise. Introduction and testing of basic vertical profiling and towed fish technology for the new project GLOBEC Germany an RV 'Prof. A. Penck'. First co-ordinated measurements and tracks together with RV Alkor. Training of new GLOBEC personnel. Presentation of IOW-measurement-and sampling technology including the MARNET-buoy-stations.

  • The cruise was conducted within the framework of the project GLOBEC-Germany II 'Trophic interactions between zooplankton and fish under the influence of physical processes'. This cruise was the first of the field program planned for the second phase of the GLOBEC project, prolonged in March 2005. Investigations were carried out in the German Bight, North Sea. Research focused on phyto- zoo- and ichthyoplankton distribution in relation to hydrographic fronts and served to measure initial conditions before the fronts are fully established. Major goals were the description of abundance and biomass of phyto-, zoo- and ichthyoplankton in different water masses across tidal mixing- and river-plume fronts. Concurrently, measurements of hydrography and fluorescence were carried out and experiments on zooplankton production (copepod egg production and egg hatching) were performed.
