were above normal about 7oC in the sea and 6°C in the entrance of Gullmar fjord. Surface salinities outside the islands were above 30 psu and the stratification weak. Surface nutrient concentrations were normal for the season, except for silicate which was high in the entrance of the Gullmar fjord Last updated: Apr 23, 2014

The temperature in the surface water was high for the season, at its lowest in the northern Baltic Proper at 16.5 °C up to almost 20 °C in the Hanö Bay. The salinity on the west coast was normal or slightly below, in the Baltic Proper it was normal except in the northeast where it was somewhat Last updated: Oct 03, 2016

-172 CRUISE REPORT FROM R/V ARGOS Survey period 2009-09-13 - 2009-09-20 Survey area The Skagerrak, Kattegat, Sound, Baltic Proper and Åland Sea. Principal SMHI SUMMARY The expedition was part of SMHI’s regular marine monitoring programme and covered the Skagerrak, Kattegat, Sound, Baltic Proper and Åland Sea Last updated: Apr 23, 2014

The coastal stations, Ref M1V1 in Kalmar Sound and N14 in the Kattegat showed normal values for the season for all parameters. At the Släggö, at the mouth of Gullmar fjord, temperature was higher than normal, while salinity was clearly below the seasonal mean. Silicate concentrations were strongly Last updated: Apr 23, 2014

metres a considerable fluorescence peak was observed at the Läsö E Seawatch Buoy. Secchi depth varied from 7-10 metres. Baltic Proper Temperature in the surface water varied between 10.8 (Fårö) – 16.8 ºC (BY1). This is normal for the season. The halocline was found at 25 metres in Arkona, at 40 metres in Last updated: Apr 23, 2014

Nutrient concentrations in Skagerrak and Kattegat were normal for the season. In the Sound silicate concentrations were enhanced. The other nutrients showed normal values. Inorganic nitrogen (DIN) had been consumed in the coastal waters of Skagerrak and in Kattegat and in all stations in the Baltic Last updated: Apr 23, 2014

The water temperature in the surface layer was essentially normal for the season. In the Skagerrak nutrient concentrations in the surface water has risen slightly since the previous survey, while they in the Kattegat showed, for the season, typical concentrations. Phosphate and silicate were Last updated: Apr 28, 2015
