In 2021, from June 4th to 23th, the research cruise with the research vessel ALKOR took place on the North Sea. Samples were taken at stations throughout the North Sea to measure organic compounds, carbon, and nutrients. For this purpose, a CTD was used for the water column and a multicorer for sediment sampling. The methodology can be used to determine the sources and sinks of organic compounds, carbon and nutrients.
