ÅRSTIDSVARIATIONER I VÄXTNÄRINGSTRANSPORTEN TILL LAHOLMSBUKTEN / Temporal Variations in Nutrient Transport to the Laholm Bay
The Laholm Bay on the Swedish west coast is a part of the estuarine system connecting the Baltic and the Atlantic. Its hydrography is characterized by a strong vertical stratification. Intensive plankton blooms and mass development of Cladophora have occurred during the last ten years. Low oxygen concentrations, and even hydrogen sulphide, have been observed in the deep water with a damaged benthic fauna and a deteriorated fishery as results.
The bay experiences a heavy nutrient load, especially of nitrogen, and eutrophication may be the main reason for the blooms. In order to justify this assumption we have compared the supply of nutrients to the surface water from various sources; mainly those from land and those from the deep water. “Complete abstract not presented.”
