Basin. Surface accumulations of cyanobacteria (blue-green algae) were observed in the northern part of the western Gotland Basin. A more detailed report describing observed algae can be found here http //www.smhi.se/oceanografi/oce_info_data/reports/havmiljoarkiv/oce_reportarchive13.html The next Last updated: Apr 23, 2014

Surface water temperatures were normal for the season in all investigated areas. All nutrients, in the surface layer, showed normal values for the season, except for phosphate which had concentrations below typical values for the summer season in the southwestern part of the Baltic Proper.

Surface water temperatures were somewhat below normal in the whole investigated area. All nutrients showed concentrations typical for the season in the Skagerrak and Kattegat, while they in the Baltic Proper were above normal. The bottom water in the Arkona Basin was well oxygenated.

mean for the season, especially in the southern parts. The bottom water in the Arkona Basin was well oxygenated. Oxygen concentrations below 2 ml/l were found at depths exceeding 80 to 90 metres in the main part of the area. Hydrogen sulphide was measured in the Eastern and Western Gotland Basins from Last updated: Apr 23, 2014

this report have been subject to preliminary quality control procedures only. Surface water temperatures were somewhat below normal in Skagerrak, otherwise typical for the season. Concentrations of inorganic nitrogen were normal in all areas. Phosphate as well as silicate showed values above normal in Last updated: Apr 23, 2014

A new agreement with the Swedish Coastguard meant that only the Swedish west coast and south western Baltic Proper (Arkona and Bornholm Basins) were sampled. In Skagerrak and Kattegat, nutrient conditions were normal for the season, except in the south of Kattegat and the Sound, were phosphate and Last updated: Apr 23, 2014

In the Baltic Proper concentrations of phosphate and silicate were higher than normal in the southern and western parts, while inorganic nitrogen showed Last updated: Apr 23, 2014

Kattegat, nutrient conditions were normal for the season. In the investigated parts of the Baltic Proper concentrations of phosphate and silicate were higher than normal, while inorganic nitrogen showed normal values. Oxygen concentrations below 2 ml/l (hypoxia) were found at depth exceeding 60 metres in Last updated: Apr 23, 2014

In Skagerrak and Kattegat, nutrient conditions were normal for the season, with the exception of silicate, that in Kattegat showed elevated concentrations. In the Sound, both phosphate and silicate levels were much higher than normal. In the Baltic Proper concentrations of phosphate and silicate Last updated: Apr 23, 2014
