Planctonema lauterbornii. To follow the surface accumulations of cyanobacteria in the Baltic Sea by satellite interpretations http //www.smhi.se/vadret/hav-och-kust/algsituationen-1.11383 The phytoplankton samples were filtered through 10 µm polycarbonate filters before being analysed using a light microscope Last updated: Apr 23, 2014

diatom species Rhizosolenia pungens was also recorded in high cellnumbers. The integrated (0-20 meters) chlorophyll a concentrations from the Baltic Sea were normal for the season at most stations. The occurrence of cyanobacteria had diminished greatly at most stations since the last expedition. Small Last updated: Apr 23, 2014

normal at two stations in the Kattegat. In the Baltic Sea the phytoplankton community was dominated by small flagellates and especially by the genus Chrysochromulina. Filamentous cyanobacteria were found in moderate abundances at the stations in the southern part but not in bloom forming quantities. Only Last updated: Apr 23, 2014

Sea were normal for the season and declared that the spring bloom had almost diminished. Only a few species of diatoms in low abundance were found at all of the Baltic phytoplankton stations. The dinoflagellate Peridiniella catenata was still quite common but the golden algae Dinobryon was the most Last updated: Apr 23, 2014

found with cell numbers above its critical limit, although there has been no reports of AST (Amnesic Shellfish Toxin) in Swedish waters, which is a toxin potentially produced by this group of algae. In the Baltic Sea the number of species and the cell numbers were low causing low chlorophyll a values Last updated: Apr 23, 2014

was similar to the one at N14 at both visits. The cell numbers were low and the most common species were small fl agellates. The diatom Chaetoceros debilis is common during spring bloom. The species was present at Släggö in low cell numbers. 3The Baltic Sea The spring bloom was obvious at all of the Last updated: Apr 23, 2014

A hierarchy of global and regional models is used to study climate variability of the North Sea and the Baltic Sea. For dynamical downscaling a high-resolution, coupled atmosphere/ice/ocean/land-surface model (RCA4-NEMO) with interactive biogeochemistry (SCOBI) is applied to calculate present and Last updated: May 03, 2018

The ice season in the Baltic Sea lasts up to 7 month and year-to-year variations of the ice coverage are very large. Since sea ice prevents heat and moisture exchange between ocean and atmosphere, a sea ice component, which is coupled to the regional Baltic Sea models, is essential for ocean Last updated: Apr 23, 2014

if we had had no long-term land elevation. Seas will continue to rise for a long time due to global warming, which will have major effects on coastal areas. However, humanity can influence how fast and how much the sea level will rise by limiting climate change. Last updated: Oct 27, 2022
