The main effort within this collaboration is 
concentrated on sources, transports, and 
sinks of suspended matter in the Elbe estuary, 
in the German parts of the Wadden Sea and in the 
German Bight. A thorough knowledge of these 
processes is important for the fate of 
pollutants which are frequently adsorbed on 
suspended particles, and their distribution in 
German Bight and in the North Sea.
