Inorganic phytoplankton nutrients in the Wadden Sea areas off Schleswig-Holstein. I. Dissolved inorganic nitrogen

Abstract

In the summer months of 1984, 1986, 1987 und 1988, several stations off the west coast of Schleswig-Holstein were investigated with regard to the situation of dissolved inorganic nitrogen. An increase in nutrients was observed during the last few years related to a decrease in salinity. This is possibly due to an increased freshwater outflow caused by higher rainfall during recent summers.
