at station Å13, of 5.2 mL/L. Chlorophyll fluorescence, measured with the CTD was low in the whole area, indicating low phytoplankton activity. The Kattegat and the Sound The sea surface temperature in the Kattegat and the Sound was normal for the season and varied between 3.4 – 5.6°C. The sea surface Last updated: Feb 19, 2021

Science and Policy Research at Linköping University is SMHI’s collaboration partner in the work package managed by Cristina Edlund, i.e. the sub-project that is drawing up a climate adaptation strategy for the Baltic Sea region. Taking a holistic approach to the Baltic Sea’s future climate adaptation Last updated: Apr 23, 2014

Rossby Centre's regional Arctic coupled ocean-ice-atmospher scenario experiments show a number of rapid sea ice loss events for projected warming Arctic climate. The nature and mechanism of those events are currently scrutinated. First results show that rapid ice loss during summer is favored by Last updated: Mar 20, 2017

stations were sampled with CTD and bottle samples, and 10 stations with only CTD. During the expedition one of the monitoring stations, Anholt E in southern Kattegat, was sampled. The sea surface temperature was above normal for the season. Concentrations of silicate and phosphorus were above normal for Last updated: Mar 12, 2021

The surface temperature was normal for the season and varied between 14.5 - 17.5 ° C in the upper water mass. In the Baltic, there was a strong thermocline throughout the area, usually at about 30 meters depth with cold underlying water, in the Kattegat the temperature in the underlying water was Last updated: Oct 10, 2019

where the depth at Landsort is 459 m. The Åland Sea has a depth of 301 m and the Bothnian Sea is 293 m deep. Volume The volume of the Baltic is 20 800 km³ and the total for the Skagerrak and the Kattegat is 6 700 km³. Drainage areas Drainage areas are the areas of land that drain into a lake or the sea Last updated: Apr 23, 2014

The temperature in the surface water was normal for the season and varied between 2.0 °C in the northern Bothnian Bay to 5.7 °C in the Åland Sea. Salinity in the surface water was also normal and ranged from 2.9 in the north to 6.0 in the southern parts. Temperature and salinity in the deep water also Last updated: Jan 21, 2020

. However, in the Baltic Proper the surface water was warmer, at about 3-4 degrees. At most stations in the western and eastern Gotland Basin, the temperature was close to four degrees, which was warmer than normal for the season. The salinity of the surface water in the Baltic Proper was still above normal Last updated: Feb 24, 2021

. The results are presented in the AlgAware algal report shortly after the expedition is completed. https //www.smhi.se/en/publications/algal-situation-reports-2-1056 This report is based on data that has undergone an initial quality control. After further quality controls, certain values or quality Last updated: Jun 01, 2020

Increased nitrate and silicate concentrations of southern North Sea origin, 20 and 13 μmol/ respectively, were recorded in the Jutland current. In the Kattegatt the spring bloom had just began in patches. The lowest oxygen concentration measured in the bottom water of Skagerrak was 4.91 ml/l at Last updated: Apr 23, 2014
