The temperature in the surface water was above normal in the Baltic Proper. The concentrations of nutrients were generally normal for the season in Skagerrak and Kattegat. In the Baltic Proper the concentration of phosphate was elevated in the western parts while the silicate concentration was well below normal in the southern parts. The effect of the inflow in December 2014 could not be detected further north than the station BY20 in the northern part of the Eastern Gotland Basin. At the station Gotland Deep BY15, hydrogen sulphide was again present in the bottom water. In the Western and Northern Gotland Basins the oxygen situation remains very serious as anoxic conditions occurred at depths exceeding 70-100 meters. Hypoxia in the bottom water was detected in the Hanö Bight, the Bornholm Basin and in the south eastern Baltic Proper.
