|The oceanographical conditions were influenced by the moderate MBI in February 1969 which terminated the stagnation period lasting since 1965. The deep water in the Bornholm and the Gdańsk Basins was supplied with oxygen beginning in Feb./March. In the eastern Gotland Basin, H2S was replaced by O2 in the bottom water step by step. First signs of the inflowing water were observed in March. In Oct. an intermediate layer containing H2S was found. The Basin was free of H2S in Nov./Dec., whereas anoxic conditions were observed in the northern and western Gotland Basin during the whole year (NEHRING & FRANCKE, 1973a).|
