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).
