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 …

, together with low nutrient concentrations, indicated that the spring bloom was coming to an end. The Kattegat and the Sound Surface water temperatures in the Kattegat were just above 12°C, which is normal for the season. During the expedition, surface temperature increased with two degree, to 14.7°C. In Last updated: Apr 23, 2014

the inflow in December 2014 could not be detected further north than the station BY20 in the northern part of the Eastern Gotland Basin. At the station Gotland Deep BY15, oxygen was again present in the bottom water. In the Western and Northern Gotland Basins the oxygen situation remains very serious Last updated: Mar 01, 2016

SMHI laboratory. No surface accumulations were observed during the cruise. At the Bornholm Basin, BY4 and BY5, and in the Hanö Bight, cyanobacteria flakes were seen in the water. Some filaments of the cyanobacteria Aphanizonemon flos-aquae were found at BY2, Bornholm basin, in the integrated samples (0 Last updated: Apr 23, 2014

less so in the Kattegat. At Å17 in the Skagerrak and Anholt E in the Kattegat, the integrated chlorophyll concentrations from 0-10 m were above normal for this month. The cyanobacteria season was finally over in the Baltic Sea. The phytoplankton diversity was low and consequently the chlorophyll Last updated: Nov 02, 2016

Surface phosphate concentration was above normal in Kattegat, the Sound and in the western and southern part of the Baltic. In the Arkona Basin. the water below the halocline was well oxygenated with levels round 4 ml/l. In the rest of the Baltic Proper oxygen concentrations below 2 ml/l were Last updated: Apr 23, 2014

Nutrient concentrations were, with few exceptions, normal throughout the investigated area. In the western part of the Arkona Basin the water below the halocline was well oxygenated with levels exceeding 4 ml/l. In the rest of the Baltic Proper oxygen concentrations below 2 ml/l were observed at Last updated: Apr 23, 2014
