The Baltic Sea is a large and almost entirely enclosed marine region, located from 53°N to 66°N latitude and from 20°E to 26°E longitude, in northern Europe. It is a brackish sea with mixed salt and fresh water. The only connection with the ocean is through the Danish straits to the North Sea. Moreover, the Baltic Sea is surrounded by a huge drain age area four times as large as the sea itself, where virtually all terrestrial human activities influence the marine environment. Nine countries are found along the Baltic Sea. Five additional countries are partially located within the drainage area.
