All nutrients showed for the season normal surface koncentrations, with the exception of phosphate that in the western Gotland Basin were clearly above normal. Oxygen concentrations below 2 ml/l were found in the whole Baltic Proper at depths exceeding 70 to 80 metres. Hydrogen sulphide was found …

Surface water salinity of the central Skagerrak was much lower than normal, 24psu. Oxygen concentrations below 2 ml/l were found in the eastern and western Gotland Basins at depths exceeding 80 metres and at Christiansö at depths exceeding 70 metres. In the Bornholm Basin the bottom water was …

Oxygen concentrations below 2 ml/l were found in the Baltic at depths exceeding 70 to 80 metres. Hydrogen sulphide was found in the Northern Baltic Proper and West Gotland Basin, at depths exceeding 80 to 90 metres. Surface phosphate and silicate levels in the northern part of the Baltic were above …

Hydrographic conditions in the greater part of the Hanö Bight, the Northern Bornholm Basin and around the Midsjö Banks were favourable for cod. Below 70 metres depth, both west and east of Gotland, oxygen concentrations were below 2 ml/l. Hydrogen Sulphide was found at three stations west of …

Nutrient concentrations were normal for the season in most areas, with the exception of the Eastern and Northern Gotland Basins where phosphate and silicate showed elevated levels. After the latest inflow to the Baltic in January, the deep waters of the Arkona Basin, Bornholm Basin and the major …

Oxygen concentrations below 2 ml/l were found in the Baltic at depths exceeding 70 to 80 metres. Hydrogen sulphide was found in the Northern and Western Gotland Basins at depths exceeding 90 to 125 metres. Surface phosphate and silicate levels in the northern part of the Baltic were above normal …

The surface water nutrient concentrations were normal or lower than normal in most areas, with the exception of the phosphate and silicate in the Baltic Proper. Phosphate levels were above normal throughout the Baltic Proper. Silicate levels were above normal only in the southern Baltic …

Western Gotland Basin: Oxygen conditions at the bottom were bad, especially on the Gotland side where levels below 2 ml/l were found deeper than 55 metres. Hydrogen sulphide was recorded from depth of 90 meters in general, but locally already from 75 meters. Eastern Gotland Basin (western part): …

Surface water temperatures were normal, except in the southern Skagerrak, Kattegat and the Sound, where the temperature was some degrees higher than normal. The concentrations of phosphate and silicate in the southern Skagerrak were higher than normal. High ammonia values were found there as …

Surface water temperatures were normal in the whole area. Silicate concentrations were raised in the Skagerrak and Kattegat. In the Sound, high phosphate and silicate concentrations were recorded in the out-flowing water from the Baltic. In Arkona and Bornholm basins both phosphate- and silicate …
