Cruise reports from the marine monitoring

During the cruise, which is part of the Swedish pelagic surveillance program, the Skagerrak, the Kattegat, the Sound, the Baltic Proper and the Gulf of Bothnia were visited.

The surface water (0–10 m) had cooled down about 4-5 degrees since November, but the temperature was normal for the season …

During the cruise, which is part of the Swedish national marine monitoring programme, the Skagerrak, the Kattegat, the Sound and the Baltic Proper were visited.

The water in the Skagerrak was well mixed which resulted in weak stratification and higher salinity in the surface water. Temperatures …

During the cruise, which is part of the Swedish national marine monitoring programme, the Skagerrak, the Kattegat, the Sound and the Baltic Proper were visited.

The cooling of the surface water had now started in all sea areas. In general, only normal surface water temperatures were noted. In the …

The temperature in the surface water in all sea areas was normal and varied between 14–18 degrees, coldest in the western Gotland Basin. In all sea areas, there was a well-mixed surface layer separated from the underlying water by a thermocline at 10–20 meters deep. The salinity of the surface …

SMHI performed an oxygen and nutrient survey within SLU Aqua’s cruise; the International Bottom Trawl Survey (IBTS Q3), that covers the Skagerrak, the North Sea and the Kattegat. SMHI joins the cruise to perform CTD measurements in connection to each trawl and to take water samples for the annual …

The slightly milder and windier weather during August resulted in a decrease in the temperature in all sea areas and was now normal at most stations. In all sea areas, there was a well-mixed surface layer separated from the underlying water of a thermocline between 15–20 m depth. At some stations …

Heating of the surface waters were observed in all visited areas with surface temperatures over 15 ℃ and with a thermocline as result, which is normal for June. The salinity varied more, about 7 psu in the Baltic Proper, between 12-18 psu in the Sound and the Kattegat. This is higher than normal in …

The warm weather during June and July increased the surface water temperature in all sea areas. All sea areas, except the Skagerrak, had higher temperatures than normal. Salinity remained higher than normal in the eastern part of the Baltic Proper and in parts of its deep water.

Dissolved …

Warming of the surface water (0-10m) at all sea basins continued in May. At several stations, the increase was about 5 ℃ compared with previous month. The salinity of the surface water at the outer stations in the Skagerrak were slightly above normal. In the Kattegat, which had salinity above …

During the cruise, which is part of the Swedish national marine monitoring programme, the Skagerrak, the Kattegat, the Sound and the Baltic Proper were visited.

The surface temperature increased in all monitored basins in April. In the Kattegat the temperature increased the most by 2℃ since the …
