A special sampling program was performed in the Hanö Bight. The winds during the expedition were moderate and had most of the time a direction from between south and east. The weather was mild with an air temperature of about 8°C. The surface water temperatures were normal. The thermocline was Last updated: Apr 23, 2014

Below this anoxic layer bottom water was oxygenated and oxygen levels had increased from about 1 ml/l to around 3 ml/l since the previous survey in March. The salinity of the bottom water had also increased with about 0.5 psu. In the northern part of the Last updated: Apr 28, 2015

The salinity was much lower than normal and varied from 19.4 psu close to the coast to 21.2 psu in the central part of Skagerrak, which indicate strong influence of outflowing Baltic water.

In the Sound, several water masses were present, with a shallow thermocline/halocline at a depth of 5 meters and a secondary thermocline/halocline at a depth of 10-15 meters. All nutrients showed, for the season, normal values in the surface water. Inorganic Last updated: Apr 23, 2014

other international studies, and indeed SMHI’s own projections, we can see for instance that the temperature in a future climate will increase in the Baltic Sea region, and that the sea level will rise.
