The strong MBI in Dec./Jan. 1975/76, terminated the short stagnation period in central Baltic deep waters. Studies in Jan. 1976 indicated O₂ concentrations up to 6 ml/l in the bottom water of the Bornholm Basin. Due to its high salinity, the inflowing water penetrated quickly into the central Baltic basins lifting up the anoxic bottom water in the eastern Gotland Basin in April/May. Only low H₂S concentrations were found here in Aug. and Nov. No anoxic conditions were observed in the bottom water of the Gdańsk and western Gotland Basins in 1976 (NEHRING & FRANCKE, 1978).
