The inflow of saline and oxygen-rich, but unusually warm water into the Baltic Sea in autumn 1997 (HAGEN & FEISTEL, 2001) temporarily interrupted the anoxic conditions in the eastern Gotland Basin between January and April 1998. From May onwards, hydrogen sulphide was again measured in the Bornholm Basin and partly in the Gdańsk Deep and, beginning in June, in the eastern Gotland Basin. Oxygen depletion continued in the deep water of the western Gotland Basin (MATTHÄUS et al., 1999a, 1999b).
