Inflows in October and late December 1998 led to the renewing of the Bornholm Basin deep water in spring 1999. From May onwards, hydrogen sulphide was measured in that basin up to the end of November when other small inflows led again to oxic conditions. In the eastern Gotland Basin, the anoxic water covered the layer between bottom and about 130 m depth all the year round. In the deep water of the western Gotland Basin, oxygen depletion has continued and H2S formation started in August (MATTHÄUS et al., 2000, 2001a).
