The bottom water oxygen concentrations in Kattegat Proper were not alarming low. In the Belt Sea concentrations below 2 ml/l were recorded at two stations, Fehmarn Belt and Mecklenburger Bucht. No surface accumulations of cyanobacteria were observed. Due to the ongoing inflow oxygen concentrations …

Nutrient concentrations in the surface waters were normal for the season almost everywhere, with the exception of phosphate, that in the south-eastern Baltic showed clearly enhanced values, and silicate that in the eastern and western Gotland Basins also showed values above normal. A …

Nutrient concentrations in the surface waters were normal for the season almost everywhere. The exception was phosphate which, south-east of Öland, was clearly above normal. Oxygen concentrations below 2 ml/l were found in the whole Baltic Proper at depths exceeding 70 metres. Hydrogen sulphide …

Nutrient concentrations were normal or near normal for the season in most areas. High values of phosphate and silicate were found in the west Gotland basin. The bottom waters in the Baltic Sea, from 70-80 metres had an oxygen concentration of less than 2 ml/l. Hydrogen sulphide was present in the …

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 …
