Temperature as well as nutrient conditions in the surface layer were normal for the season in all areas. Oxygen concentrations below 2 ml/l were generally found at depths exceeding 60 to 70 metres in the whole Baltic Proper. Hydrogen sulphide was found in the deep water in the eastern Gotland Basin Last updated: Apr 23, 2014

Nutrient concentrations in all areas were normal or slightly lower than normal for the season in all areas. The deep water of the Bornholm Basin, the Hanö Bight, southeast of Baltic Proper and east of Gotland was well oxygenated. Hydrogen sulphide was present in the northeast and west Gotland Last updated: Apr 23, 2014

from 0.15 in the south to 0.76 µmol/l in the north, silicate levels ranged from 3.2 to 10.4µmol/l. Oxygen levels in deep waters of the Arkona Basin and Hanö Bight were good, about 5-6 ml/l and 2.6 ml/l. Though a small inflow was detected during the previous cruise oxygen levels were back to almost Last updated: Apr 23, 2014

In the eastern Skagerrak there were a bloom of a flagellate, Emiliania Huxlley, which gave the surface water a turkos colour and caused low visibility with secchii depths <3m. The surface temperatures varied between 14-15 deg in the Skagerrak-Kattegatt and between 11-13 in the Baltic Proper. The Last updated: Apr 23, 2014

The surface water temperatures were In the Skagerrak 3.5°C - 5.3°C, the Kattegat -0.5°C - 2.7°C and in the Baltic 1.2°C - 3.4°C. The nutrient concentrations in the surface layer in the Kattegat showed lower and chlorophyll much higher values than expected for the season. This means that the Last updated: Apr 23, 2014

Eutrophication is a severe threat to the Baltic Sea ecosystem. During recent decades, eutrophication-associated problems - such as deep water oxygen deficiency, the spreading of dead bottom zones, increased frequency and intensity of cyanobacterial blooms - have been observed. The ability to bind Last updated: Nov 22, 2023

The weather was mostly cloudy and hazy. Moderate to strong winds from the west dominated. The surface water temperatures were normal for the season in the whole area i.e. about 5°C in the Skagerrak, 3°C in the Kattegat and between 2 and 4°C in the Baltic. The spring bloom in the Kattegat continued Last updated: Apr 23, 2014
