Ziel der Reise / Objectives of Cruise:

The voyage on RV ALKOR (AL557) supports three projects dedicated to the study of material cycles and how they are influenced by climate and anthropogenic change. The focus of the data collected is on the German Academic Exchange Service (DAAD). German Academic Exchange Service (DAAD) The ocean's alkalinity - connecting geological and metabolic timescales, which is funded by the BMBF within the framework of "Make Our Planet Great Again". is financed. Furthermore, the BMBF supports the cruise within the FONA / MARE:N project CARBOSTORE, as well as within the framework of the DAM pilot mission Mobile Ground-touching Fisheries (MGF). In a large station grid (about 1 degree x 1 degree), the water column is sampled with a CTD rosette and the sediment was sampled with a multicorer. These samples help to measure the distributions of CO2, nutrients, trace metals and organic compounds in the North Sea to qualitatively and quantitatively determine their sources, sinks and transport pathways. In addition, to better understand the contribution of sediments and benthos to marine cycles in the water column, we measured the intensity of the exchange of nutrients and CO2 between sediment and the water column.
