Because of the November 1996 inflow, the central Baltic deep water became oxic until May. From August onwards, the layer below 150 m in the eastern Gotland Basin again became anoxic. The western Gotland Basin deep water continues to be oxic. In September, an inflow of exceptionally warm, saline and oxygenated water occurred, later identified as a moderate MBI (MATTHÄUS, 2006). At the end of October, the oxygen-rich water crossed the Słupsk Furrow into the central Baltic Sea (MATTHÄUS et al., 1998a, 1998b).
