Expeditionsrapporter från utsjöövervakningen

In the Baltic Sea and the Gulf of Bothnia normal concentrations of nutrients were found. In the Kattegat and the Skagerrak lower concentrations of nutrients than normal were observed. In the south-western part of Skagerrak was an indication of ongoing production. In the Gotland Basin hydrogen …

A special sampling program was performed in the Hanö Bight. The winds during the expedition were moderate and had most of the time a direction from between south and east. The weather was mild with an air temperature of about 8°C. The surface water temperatures were normal. The thermocline was …

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 …

. The surface water temperatures, which at the last cruise generally were the highest on record, had now decreased to or near to normal values. However, the thermocline had simultaneously shifted downwards in the water column. In the Skagerrak and the Kattegatt the surface water was more or less …

The expedition was performed within SMHIs regular marine monitoring programme and covered the Skagerrak, the Kattegat, the Sound and the Baltic Proper. Because of the flooding of the rivers Wisla and Oder a part of the expedition was destinated to study the effect of the overflow in the areas of …

Due to the floodings in Poland and Germany, this expedition was carried out with the main purpose to study the spreading and material transports of river water into the Baltic. The expedition was carried out in cooperation between SMHI, NSEPA, The Fishery Board, IVL and the Swedish Coast Guard as …

Because of the overflow of river Wisla a great part of the expedition was destinated to the Southeast of the Baltic to study the effect of the overflow in the area of the Bay of Gdansk. To facilitate this the regular programme was reduced. Temperature, salinity and fluorescence (biological …

Skagerrak: The surface temperatures varied between 10-14°C. The nutrient concentrations above the halocline showed low but, for the season, normal values. A strong bloom of Emiliania Huxleyi was observed in the area. Kattegat and the Sound: The surface temperatures varied between 12-13°C in the …

Skagerrak: The surface temperatures varied between 5.5 and 5.9°C. The nutrients concentrations above the halocline showed, for the season, normal values. Kattegat and the Sound: The surface salinity was higher than normal.The pycnocline started between 4 and 15 metres depth and was weakly …
