Cruise reports from the marine monitoring

In large parts of the deep water in the Baltic Proper the oxygen concentrations were close to zero. Completely oxygen free conditions, when hydrogen sulfide is measured, was found in the Western Gotland Basin from 90 meters depth and in the Eastern Gotland Basin, but then only in the Gotland Deep …

The expedition was included within SLU:s International Bottom Trawl Survey and covered the Skagerrak and the Kattegat. Mapping of winter nutrient conditions was performed in the Skagerrak and 12 stations with complete hydrography were sampled, 3 ordinary SMHI stations were sampled due to a storm …

In large parts of the deep water in the Baltic Proper the oxygen concentrations were close to zero. Completely oxygen free conditions, when hydrogen sulfide is measured, was found in the Western Gotland Basin from 100 meters depth and in the Eastern Gotland Basin but then only in the Gotland Deep …

All nutrients in the surface water were generally normal for the season, except in the Baltic Proper where concentrations of silicate were higher or much higher than normal. The surface water temperature was normal for the season except in the Skagerrak where it was colder. The surface salinity was …

In large parts of the deep water in the Baltic Proper the oxygen concentrations were close to 0 ml/l and the concentrations of hydrogen sulphide were lower than the expedition in December. In the northern part of the Western Gotland Basin (BY31) hydrogen sulphide was found from 175 meters, and in …

In large parts of the deep water in the Baltic Proper the oxygen concentrations were found to be around 0 ml/l, but no high concentrations of hydrogen sulphide was found. Though, in the Western Gotland Basin, hydrogen sulphide was found from depth exceeding 80 meters. Acute hypoxia, < 2 ml/l was …

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 …

The temperature in the surface water was now normal and the cooling of the surface water had started. This was clearly seen in the Skagerrak and Kattegat. The salinity showed normal values in the whole investigated area. Generally, the nutrient concentrations in the surface water had increased …

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 …

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 …
