In the summer months of 1984, 1986, 1987 and 1988, several stations off the west coast of Schleswig-Holstein were investigated with regard to the situation of ortho-phosphate, reactive silicate and mesozooplankton. An increase in phosphate was observed, whereas an increase in silicate could only be found in the areas influenced by the River Eider. Polychaete larvae show a decreasing tendency in the summer months; this is thought to be influenced by water temperature.
