There was no increased nutrient concentrations recorded in Skagerak or Kattegatt and the spring bloom had not began. The oxygen condition in the bottom water of Skagerrak was good and no station recorded a saturation below 90%. In the bottom water of Kattegatt the lowest recorded oxygen …

Very high surface phosphate concentrations were measured in the Baltic Proper. Silicate showed enhanced concentrations there though nitrogen compounds were normal. Nutrient concentrations in the Skagerrak and Kattegat were normal or almost normal. In the Baltic Proper oxygen concentrations were …

Surface water temperatures in the Skagerrak and the Kattegat were above normal. High nutrient concentrations were found in the surface waters outside of Gullmarfjord, due to recent heavy rain. Concentrations in the southeastern Skagerrak were also high, due to influence from southern North Sea. An …

Western Gotland Basin: Oxygen conditions at the bottom were bad. Concentrations below 2 ml/l were found deeper than 50 to 70 metres. Hydrogen sulphide was recorded from depth of 80 meters in general, but locally already from 70 meters. Eastern Gotland Basin (western part): Oxygen levels below 2 …

Surface water temperatures were somewhat higher than normal on the west-coast, though close to normal in the Baltic Proper. Nutrient concentrations in the surface water were elevated in the Kattegat and the eastern part of Skagerrak. In the Baltic, surface concentration of phosphate was higher than …

Surface water temperatures were several degrees above normal. Surface nutrient concentrations were mostly normal. Oxygen concentrations below 2 ml/l were observed at depths exceeding 60 to 80 metres throughout the Baltic Proper and in the bottom water of south-eastern Kattegat and the …

Surface water temperatures were higher than normal in the whole investigated area. Nutrients showed typical early autumn values, on the west coast as well as in the Baltic Proper. Oxygen concentrations below 2 ml/l were observed at depths exceeding 70 – 80 metres in the Baltic. Hydrogen …

In the Skagerrak, 11 stations with complete hydrography were taken. In the Kattegat mapping of oxygen conditions in bottom water was performed, 10 stations with complete hydrography and 14 with oxygen and salinity near bottom were sampled. The lowest oxygen concentration measured in the bottom …

Surface water temperatures were slightly higher than normal in the main part of the investigated area. Nutrients showed typical summer values in the Baltic Proper and in the main part of the Kattegat and Skagerrak. Oxygen concentrations below 2 ml/l were observed at depths exceeding 60 to 80 …

Surface water temperatures were higher than normal in the whole investigated area. Nutrients showed typical summer values, on the west-coast as well as in the Baltic Proper. Oxygen concentrations below 2 ml/l were observed at depths exceeding 70 meters in the Baltic. Hydrogen sulphide was found …
