interrupted with a short stop in Visby on the 19th to pick up additional personnel. The weather was dominated by steadily increasing air pressure, from 1000 to 1024 hPa. Initial cloud broke up during the first day, leaving clear skies for the rest opf the week. Apart from fresh north westerly winds in the Last updated: Apr 23, 2014

the cruise, when they were strong. Wind directions between south and west dominated. Due to permits not granted, to enter Latvian waters, some stations had to be moved into Swedish EEZ. Skagerrak Surface water temperatures were normal for the season and varied from 8.5°C in the western parts to 9.1°C Last updated: Apr 23, 2014

Kattegat, surface nutrient was normal for the season in most of the investigated places. In the Baltic Proper, except the Arkona Basin, the concentrations of phosphate and silicate were higher than normal. The oxygen concentrations in the bottom water in the Hanö Bight and the Bornholm Basin had increased Last updated: Apr 23, 2014

water temperatures were slightly above normal except in the Sound were the temperatures was normal and varied from 19.5°C to 16.7°C. Surface salinity increased from 16.7 psu in the east to 19.2 psu in the north, while it was about 8.0 psu in the Sound. The halocline and thermocline were both found at a Last updated: Apr 23, 2014

silicate showed elevated levels. In the investigated parts of the Baltic Proper concentrations of phosphate and silicate were higher than normal, while inorganic nitrogen showed normal values. Oxygen concentrations below 2 ml/l (hypoxia) were found at depth exceeding 60 metres in the Bornholm Basin as well Last updated: Apr 23, 2014

increased from 18.5 psu in the south to ca. 20 psu in the north. In the Sound surface salinity was 11 psu. Thermocline and halocline were found at 15 meters depth in the whole area. All nutrients showed, for the season, normal values in the surface water. Inorganic nitrogen was below the detection limit (0 Last updated: Apr 23, 2014

Surface water temperatures as well as surface salinities were at normal levels for the season in the whole investigated area. Surface nutrient concentrations were normal in most areas, with the exception of silicate that showed levels below normal in the main part of the Baltic Proper. The oxygen Last updated: Apr 23, 2014

The weather was dominated by weak to moderate northerly winds. The surface water temperatures showed normal values. In the surface water of the Skagerrak the nutrient contents were low. In the surface water of the Kattegatt and the Baltic, outside the Sound area, the nitrogen componds were below or Last updated: Apr 23, 2014

to moderate mainly from south. During the last days however, south-westerly winds with gale force dominated. Because of lack of time due to this, no visit could be made at BY38. Water sampling in the Baltic Proper was done from intermediate depths with low oxygen concentrations, for identifying Last updated: Apr 23, 2014
