Oxygen concentrations below 2 ml/l were found at the bottom in Skälderviken, in the Sound from 15 metres, in western Arkona bassin from 40 meters and in the rest of the Baltic Proper at depths greater than 60 to 80 metres. The hydrogen sulphide layer started in the Bornholm Basin at a deep of 90 to 70 metres, in the eastern Gotland Basin at a deep of 140 to 125 metres and in the western Gotland Basin already at a deep of 90 to 80 metres.
