The Baltic Sea (German: Ostsee; Polish: Morze Bałtyckie, Bałtyk; Russian: Балтийское море; Danish: Østersøen; Swedish: Östersjön; Lithuanian: Baltijos jūra; Latvian: Baltijas jūra; Estonian: Läänemeri; Finnish: Itämeri) is a sea of the Atlantic Ocean, enclosed by Scandinavia, Finland, the Baltic countries, and the North European Plain. It includes the Gulf of Bothnia, the Bay of Bothnia, the Gulf of Finland, the Gulf of Riga, and the Bay of Gdańsk. The sea stretches from 53°N to 66°N latitude and from 10°E to 30°E longitude. A mediterranean sea of the Atlantic, with limited water exchange between the two bodies, the Baltic Sea drains through the Danish islands into the Kattegat by way of the straits of Øresund, the Great Belt, and the Little Belt.
