The continuation of the stagnation period caused the deterioration of the oxygen conditions in central Baltic deep waters in 1975. H₂S was observed in the Bornholm and Gdańsk Basins in May, August and Oct./Nov. In the eastern Gotland Basin anoxic conditions prevailed in all seasons. With the exception of the Landsort Deep station, H₂S had developed in the northern and western Basins in August and Oct./Nov. 1975 (NEHRING & FRANCKE, 1976b).
