Research project Reducing nutrient loading from land to the coast can be done in various ways. However, there is a lack in knowledge concerning the effect of different types of measures, especially for the northern parts of the Baltic. In this project we closely monitor the effects of nutrient reductions on the biota and biogeochemical processes in a bay in the northern Baltic Sea.
Eutrophication symptoms, such as algal blooms and oxygen depletion, vary along the north-south biogeochemical gradient in the Baltic Sea, with the most severe symptoms in the southern parts. Locally, however, eutrophication is a problem also along the coast in the northern parts of the Baltic Sea. In this project, we aim to reduce nutrient loading to an eutrophicated northern Baltic Sea bay, and to closely monitor the effects of nutrient reductions on the biota and biogeochemical processes in the bay.
