Ueberwachung und Ermittlung des zeitlichen Verlaufs der Veraenderungen des biologischen Seebodenzustandes als Indikation fuer die Belastung mit organischem Material. Biologische Anlayse des Makro-Zoobenthos besonders der Tubificiden, sowie begleitende physikalische und einfache chemische Anlayse der Sedimente.
Conductivity-temperature-depth profiles were measured using a Seabird SBE 911plus CTD during RV HEINCKE cruise HE660. The CTD was equipped with duplicate sensors for temperature (SBE3plus), conductivity (SBE4) and oxygen (SBE43). Additional sensors such as a WET Labs C-Star transmissometer, a WET Labs ECO-AFL fluorometer and an altimeter (PSA-916 Teledyne (Benthos)) were mounted to the CTD. Temperature, conductivity and oxygen sensors are calibrated by the manufacturer once a year before being mounted in January. They are used throughout the year and no post-cruise or in-situ calibration is applied. All other sensors are calibrated irregularly. Data were connected to the station book of the specific cruise as available in the DSHIP database. Processing of the data including removal of obvious outliers followed the procedures described in CTD Processing Logbook of RV HEINCKE (hdl:10013/epic.47427). The processing report for this dataset is linked below.

Sammeln von Proben im Gelaende: An verschiedenen Orten; Mehrfach oder regelmaessig an denselben Stellen; Vergleich mit entsprechenden Biotopen anderer Regionen, bisher Frankreich, Skandinavien, Ostafrika, Binnenlaendische Salzstellen).
Raw physical oceanography data was acquired by a ship-based Seabird SBE911plus CTD-Rosette system onboard RV HEINCKE . The CTD was equipped with duplicate sensors for temperature (SBE3plus) and conductivity (SBE4) as well as one sensor for oxygen (SBE43). Additional sensors such as a WET Labs C-Star transmissometer, a WET Labs ECO-AFL fluorometer (FLRTD) and an altimeter (Teledyne Benthos PSA-916) were mounted to the CTD. The data was recorded using pre-cruise calibration coefficients. No correction, post-cruise calibration or quality control was applied. Processed profile data are available via the link below.
We have estimated the standing stocks in carbon units per m² in the Baltic Sea ecosystem for 18 living and non-living groups relevant to carbon cycle and management activities in the Baltic Sea. We included three non-living apartments: POC, DOC and sediment carbon. The living groups comprise: phytoplankton, protozooplankton, bacteria, zooplankton, macrophythes, benthos, plaice, flounder, herring, sprat, cod, ringed seals, seals, grey seals and harbour porpoises. The estimates are based on ICES raw data and literature data and represent spatial and temporal averages. Data, data sources, assumptions and calculations are described in detail to ensure reproducibility.
We collected, formatted and standardized publicly available data from publications and databases for 24 living carbon pools in the North Sea and calculated the carbon stock of these pools per m². The living groups include: Phytoplankton, Protozooplankton, Bacteria, Mesozooplankton, Zooplankton, Phytobenthos, Zoobenthos, Cod, Haddock, Saithe, Whiting, Norway pout, Herring, Sandeel, Sprat, Other fish, Grey Seal, Harbour Seal, Minke Whale, White beaked dolphin, Harbour porpoise, Bottlenose dolphin and White-sided dolphin. Estimates are based on the standing stock biomass of the studied organism groups and represent spatial and temporal averages. Data, data sources, assumptions and calculations are described in detail to ensure reproducibility. The data collection was carried out in the course of the project Anthropogenic impacts on particulate organic carbon cycling in the North Sea (APOC) funded by the German Federal Ministry of Education and Research (BMBF).
