Ziel der Reise / Objectives of Cruise:
Chemical and oceanographic monitoring of the German Bight. As part of the marine environmental monitoring, water samples are taken to be analysed for nutrients and other chemical oceanographic parameters (pH, alkalinity, chlorophyll a). In addition, automatic flow through (pH, alkalinity) will be used. At a reduced number of stations water samples will be taken to determine the phytoplankton communities and vertical hauls will be carried out with a WP2 net to record the zooplankton communities. Accompanying hydrographic measurements using a CTD and ADCP system will complete the data set. At stations close to the shipping route, ship emission measurements are carried out.
