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 …

The early spring bloom has finished in the Skagerrak and Kattegat. Surface nutrient concentrations were still low. The spring bloom had not really started in the Baltic Proper and nutrient concentrations were normal, with the exception of phosphate which was high, particularly in the southern …

Nutrient concentrations were normal throughout the investigated area with the exception of silicate, concentrations, which were elevated in the Kattegat. The water below the halocline in the Arkona Basin was well oxygenated with levels of ca. 6 ml/l. In the rest of the Baltic Sea, oxygen …

Surface water temperatures were normal throughout the study area. Nutrient concentrations in the surface waters were mostly normal in all areas except for phosphate, which was higher than normal in the Arkona Basin. The deep water in the Arkona Basin was well oxygenated: 4.7-6.6 ml/l. In the …

Nutrient concentrations were normal in the whole investigated area, with the exception of phosphate that showed elevated levels in the southern part of the Baltic Proper. The water below the halocline in the Arkona Basin was well oxygenated with levels of ca. 5 ml/l. In the rest of the Baltic …
