Skagerrak: Surface temperatures varied between 2.5 and 4.5 oC and surface salinites from 30 in the east to 33.5 in the southwest. The pycnocline was located at a depth of 15 meters in the eastern part and at 30 meters along the Jutland coast. A bloom had started along the Swedish west coast and the …

Oxygen concentrations below 2 ml/l were found in the Baltic at depths exceeding 70 to 80 metres. Hydrogen sulphide was found in the Northern Baltic Proper and West Gotland Basin, at depths exceeding 80 to 90 metres. Surface phosphate and silicate levels in the northern part of the Baltic were above …

During the expedition the weather was rather cloudy and windy. In the southern Baltic there was a strong wind from southwest. In the Skagerrak sampling was done only at station P2, because wind velocities more than 20 m/s were forecast. The surface water temperatures were between 8 and 11°C in the …

During the expedition the weather was rather cloudy and windy, especially during the first half part. Winds from the west were dominating. The surface water temperatures were between 15-16°C in the whole area with exception of a region with upwelling south Utklippan, where the temperature was only …

Temperature and salinity in the surface water was normal throughout the investigated area. The phosphorus concentration remains elevated in the south Baltic Proper and the Sound. All inorganic nitrogen (DIN) had been consumed in the surface water at all stations. High silicate concentrations were …

On the Öland side of the West Gotland Basin oxygen conditions at the bottom were good. The lowest recorded concentration was 3.1 ml/l at a depth of 66 meters. The lowest recorded concentration in the Bordholm Basin was 1.0 ml/l at a depth of 60 meters. Other 10 stations in the Hanö Bight had oxygen …
