In February/March, H₂S was present in the deep water of the Bornholm Basin. Inflow events, not reaching the intensity of MBIs, supplied this basin with oxygen in April/May. Oxic conditions were observed in the Gdańsk Basin during the whole year. H₂S was present in the deep water of the eastern Gotland Basin during 1986. Oxic conditions prevailed below the halocline in the northern and western basins, except in the Karlsö Deep with anoxic conditions near the bottom in November 1986 (NEHRING & FRANCKE, 1987b).
