In March/April 1973, H2S was only present in the western Gotland Basin, whereas in the bottom water of the other basins oxygen was measured. Oxygen conditions deteriorated in May/June. H2S was observed in the bottom water of the Fårö Deep and in the northern and western Gotland Basins. In August, the southern part of the eastern Basin was free H2S. In November anoxic conditions had developed in the eastern and northern Gotland Basins (NEHRING & FRANCKE, 1975). Discrepancies between the maps and the explaining text are explained in chapter 6, p. 21.
