Inflows into the Baltic Proper, not reaching the intensity of MBIs pushed away the anoxic deep water in the Bornholm and Gdańsk Basins and supplied them with oxygen in March. In November, anoxic conditions returned in the Bornholm Basin, but not in the Gdańsk Basin. The eastern Gotland Basin was characterized by stagnant conditions with very high concentrations of H2S (cf. Fig. 3). Oxygen was present in the deep water of the northern and western Gotland Basins during the whole year (NEHRING, 1991).
