The MOSES test campaign ELBE 2020 includes activities along the middle reaches to the tidal Elbe river and the German Bight. The inland Elbe river part of the campaign covers physico-chemical parameters from various sites along the Elbe River and its main tributaries. The sampling was conducted in a Langrangian way according to travel time, particularly between Aug 04 to Aug 12. Discharge in Magdeburg was 241 m³/s which is about mean low discharge (231 m³/s). Physico-chemical parameters as well as nutrients were sampled using the research vessel ALBIS from Schmilka (km 4, German border) to Geestacht (km 585, close to Hamburg). The targets were water quality measurement by multiparameter probes and chemical analyses, the detection of phytoplankton growth and decrease of dissolved nutrients along the river.
