concentrations in the surface layer were at normal low levels for the season, higher values were found below the halocline which is normal. Silicate concentrations in the surface layer in the Baltic Proper continued to be somewhat higher than normal, however not as high as earlier this year or last year.

, Seatrack Web, has been used to monitor emissions in the Baltic Sea and the eastern North Sea. Seatrack Web produces dispersion forecasts for how pollutants, such as oil, move around. This makes it possible to plan decontamination work and also makes the work easier, both at sea and along the coastal Last updated: Apr 23, 2014

Arctic sea-ice extent reduction records continue to be set. Recent studies of the atmospheric impact on sea-ice reduction have used reanalysis data and satellite observations. A reoccurring conclusion from these studies is the anomalously large convergence of atmospheric heat and moisture and the Last updated: Mar 20, 2017

small amounts of phosphate was measured. Surface concentrations of silicate were still above normal in the whole investigated area. The surface water temperature in the investigated area was normal to colder than normal for the season. The salinity in the surface water was normal except from the Last updated: Sep 22, 2017

The temperature in the surface water was now normal or slightly lower than normal for the season. The salinity showed normal values except in the eastern part of Skagerrak, the Sound and the Gotland Deep (station BY15) where the salinity was above normal. The nutrient concentration in the surface Last updated: Dec 21, 2016

The temperature in the surface water was normal for the season and varied between 16 and 18 °C. The salinity in the surface waters on the west coast was normal, in the southwestern parts of the Baltic Proper it was slightly above normal and somewhat below normal in the northern parts of the Eastern Last updated: Sep 01, 2016

The surface salinity was generally lower than normal except for the north part where it was normal and ranged from 17.8 to 25.3 psu. In the Sound the salinity Last updated: Mar 01, 2016
