Surface temperatures were higher than normal in the Skagerrak and the Kattegat. Nutrient concentrations in the surface layer were normal for the season with exception of higher phosphate and silicate level in the southern Kattegat In the northern Kattegat (Fladen) bottom water oxygen concentration Last updated: Apr 23, 2014

Low oxygen concentrations were found in the bottom water at Lundåkrabukten 1.95 ml/l and Skälderviken 1.51 ml/l. In the south east parts of Kattegatt the oxygen concentrations varied between 2.3 to 3.0 ml/l.

During the first part of the expedition the weather was dominated by strong winds, reaching storm strength in the Baltic. The second part was dominated by weak to moderate winds. The nutrients showed normal values in the surface water in the whole area. Hydrogen sulphide was detected in the Gotland …

In the Kattegat phytoplankton sampling according to BMP was performed. Maxima of fluorescence were seen in the Kattegat below the halocline at about 20 m and in the Sound at about 10 m. Almost all over the area there were low concentrations of phosphate and depletion of nitrite and nitrate. …

In certain areas of the Baltic proper strong blooms of potentially toxic bluegreen algae (Nodularia) and dinoflagellates were observered. The observations were supported by sharp fluorescence maxima in the water. The extent of oxygen depleted, sulphidic, bottom water in the Gotland Basin had …
