Hydrography of the Dutch Wadden Sea
In this paper an attempt has been made to describe for the Dutch Wadden Sea water movement, transport of suspended matter and the cycle of suspended organic matter. Stress has been laid on the fact that these are related subjects, which therefore ought to be studied in combination. The discussion was based on observations made in the years 1949-1951 in the southwestern part of the area. A summary of the figures found from these observations is given in Table 23 in the report. For a good understanding of the results two facts appear to be of primary importance. First, there is a considerable exchange of water between Wadden Sea and North Sea, which is constantly at work to change Wadden Sea conditions, so that they approach those of the North Sea. Secondly, the concentration of light suspended material (silt) and of suspended organic matter is, notwithstanding this exchange, constantly higher in the Wadden Sea than in the North Sea
