expedition was part of SMHI’s regular marine monitoring programme and covered the Skagerrak, Kattegat, Sound, Baltic Proper and Gulf of Bothnia. This report is based on preliminary, part-quality controlled data. Most parameters showed values typical for the season, except phosphate and silicate that showed Last updated: Apr 23, 2014

Since RH 2000 became official in 2005, a transition to the new reference system has been ongoing at Sweden's municipalities, government agencies and other societal stakeholders. For example, the Swedish Maritime Administration is gradually adapting the Swedish nautical charts to RH 2000 (Baltic Sea Last updated: May 29, 2019

The salinity is 3-4 psu in the Bothnian Bay, 5-6 psu in the Sea of Bothnia, 6-9 psu in the Baltic Proper and 15-30 psu in the Skagerrak and Kattegat. Since fresh water is lighter, it takes more fresh water in the Baltic to balance the sea level outside – thus mean sea level in the Baltic is higher Last updated: Apr 23, 2014

authority principals to stop and rethink. "There were acute problems getting the water from the plant to run out to sea, and there was a risk that seawater might flood into the treatment basins - which would have been absolutely devastating," says mechanical engineer Rikard Widén of Gotland Municipality Last updated: Apr 23, 2014

The oxygen situation in the deep water of the Baltic Proper continues to be serious. The bad conditions measured during the beginning of the 2100-century continues.

. Seaweed and rubbish collect in water gyres The Coriolis effect has further consequences. The winds over the seas set the sea surface in motion in the direction of the wind, and the water’s inner friction (viscosity) pulls the water from the layer below. Because of the Coriolis effect this movement Last updated: Apr 23, 2014

overlying water masses, is something that the process studies can give an estimate on.   In order to calculate how the ice cover in the Arctic will develop, complex models that couple the sea-ice-atmosphere system are used. In these models, a number of the processes may be studied in more detail. One may Last updated: Mar 20, 2017

salinity was observed to be within normal range at all sampling points, with the exception of the south Baltic Proper, where sea surface salinity was slightly above normal. Dissolved inorganic nitrogen and phosphorus displayed low concentrations, which is normal for the season. The silicate levels in all Last updated: Aug 07, 2023
