Abstract

In the present paper we discuss the relationship between nutrient discharge and eutrophication conditions in the German Bight during summer. Nutrient inputs into this area are controlled by the discharge rates of, and the biological processes in its major nutrient supplier — the river Elbe. The shape and direction of the nutrient plume are modulated by wind stress. Eutrophication conditions were inferred from oxygen deficiency associated with remineralization in cold bottom layers in areas deeper than 20 m. Thermocline breakup appeared only following 4 days periods of wind forces > 7 Bft. By repeated investigations of the same station grid within 4 days, high variability of nutrient gradients is documented.
