Most parameters showed values typical for the season, except phosphate and silicate that showed elevated concentrations in some parts of the Baltic Proper. Oxygen concentrations below 2 ml/l were observed at depths exceeding 50 to 80 metres in the main part of the Baltic Proper and from 125 metres in the northern Gotland Basin. Hydrogen sulphide was found in the Eastern and Northern Gotland Basins from 90 to 130 metres, in the Western Gotland Basin deeper than 70 to 90 metres and in the bottom water of the Bornholm Basin.
