Ziel der Reise / Objectives of Cruise:

During the research survey with VWFS DENEB from June 06 to 16, 2023, the monitoring of the German Exclusive Economic Zone in the Baltic Sea for artificial radioactivity will be carried out within the framework of the marine monitoring of the BMUV on the basis of the Radiation Protection Act (StrlSchG) according to ? 161 para. 1 No. 1 letter c, the IMIS Responsibilities Ordinance (IMIS-ZustV) according to ? 6, the General Administrative Regulation on the Integrated Measurement and Information System for Environmental Radioactivity Monitoring (AVV-IMIS) according to Annex 1 points 3. 2.5 as well as 8.1 No. 3.2 and the HELCOM Commission according to HELCOM Recommendation 26/3. During the survey, seawater, marine suspended matter and marine sediment samples are collected for the determination of artificial radionuclides, accompanied by hydrographic measurements with a CTD probe. Seawater samples are collected from the surface and from the water column, the latter using a 12 x 30-L rosette. Marine sediment samples are collected using a Gemini corer, small box corer, or cheeks corer. The suspended matter samples are collected using a flow-through centrifuge in a separate centrifuge laboratory container. To reduce the volume to be transported, seawater samples are pre-treated on board where possible. To expand the available laboratory space, the radioactivity laboratory container is brought on board.
