Inflow events of moderate and weak intensity occurred between October and December 1971, causing the deep water renewal of the Bornholm and the Gdańsk Basins in April and May 1972. In August, the bottom water of the eastern Gotland Basin was renewed lifting up H₂S into the intermediate layers. Anoxic conditions were observed in parts of the eastern Gotland Basin as well as in the northern and western Gotland Basins in Oct./Nov.1972 (NEHRING & FRANCKE, 1974).
