In many situations it is important to be able to make ocean forecasts; to issue warnings about risk of flooding in coastal areas, to make forecasts of e.g. oil-drift spill, ice formation, ice compression, and wave height. The Operational oceanographic research group develops models and tools to …

Nutrient concentrations were higher than normal for the season in the central Skagerrak. Phosphate and silicate concentrations were enhanced in the southern Baltic and in the Sound. Measurements of fluorescence and oxygen saturation indicated that the spring bloom was underway in the Kattegat and …

Oxygen conditions in the main part of the Hanö Bight, around the Midsjö Banks and in the Northern part of the Bornholm Basin were good. Oxygen concentrations below 2 ml/l were found, both west and east of Gotland, at depths excceding 70-80 metres. Hydrogen sulphide was found at three stations west …

The water temperature was to some extent elevated in the north Baltic Proper. Nutrient concentrations were normal in most basins with the exception of the southern and eastern parts of the Baltic Proper where phosphate showed elevated concentrations. The spring blooms had not started in the Baltic …

Kattegatt and the Sound nutrient concentrations showed normal values. The oxygen condition in the bottom waters of the area was good and most stations showed values over 90% oxygen saturation. The spring bloom had not yet started.

Surface water temperatures were somewhat above normal in Kattegat and the Baltic Proper. All nutrients, showed normal winter values in the whole area, with the exception of phosphate, that showed elevated concentrations in the Southern Baltic Proper. In no areas, any sign of spring bloom was …

Surface water temperatures were above normal in the Baltic Proper. All nutrient concentrations were normal for winter with the exceptions of phosphate, which was above normal in the Southern Baltic Proper and Kattegat, and silicate that was higher than normal in the Kattegat. No sign of a spring …

Mapping of winter nutrient conditions was performed in the Skagerrak and 16 stations with complete hydrography were sampled. In the Kattegatt area 18 stations were sampled with complete hydrography. The silicate levels were slightly enhanced compared to the normal in the Skagerrak. The other …

An early spring bloom occurred in the Skagerrak and Kattegat, resulting in low nutrient concentrations at the surface. In the Baltic Proper, the spring bloom had not started and nutrient concentrations were normal, with the exception of phosphate which was higher than normal. Surface water …

Oxygen conditions in the main part of the Hanö Bight, around the Midsjö Banks and in the Northern part of the Bornholm Basin were moderate, with at least 2 ml/l oxygen shallower than 60 metres at all stations. Lower concentrations were found between 60 metres and the bottom. No hydrogen sulphide …
