   Sammanfattning : The Baltic Sea is one of the world’s largest brackish water environments and is today suffering from, for example, eutrophication, spreading hypoxia, accumulations of contaminants and invasive organisms. These problems exist due to a combination of natural features that makes the Baltic Sea a sensitive ecosystem (such as long water residence time, limited water exchange, large catchment area), and anthropogenic pressures on land, (such as agriculture and land-use changes, large human populations and industries) and in the sea (such as transport, fishing and bottom-trawling).
