The Baltic Sea – basic information

The Baltic is a young sea, quite shallow, semi-enclosed and with low salinity. Someone could say – boring, but we say – unique in the world!

The Baltic Sea is one the largest brackish water bodies in the world, connected with the North Sea by three narrow Danish Straits: the Øresund, the Great Belt and the Little Belt. The water exchange with the North Sea is very limited and fact largely influences the specific conditions in the Baltic. The Baltic Proper is bordered on its northern edge, at latitude 60°N, by the Åland Islands and the Gulf of Bothnia, on its northeastern edge by the Gulf of Finland, on its eastern edge by the Gulf of Riga, and in the west by the Swedish part of the southern Scandinavian Peninsula.

The area of the Baltic is approx. 415.266 km² and its catchment area covers 1.721.233 km². The catchment area is therefore 4 times higher than the area of the sea basin.

Main geographical characteristics of the Baltic.

The coastline of the Baltic, measuring 8.100 km, is very varied. The Polish coast is characterised by sandy beaches, peninsulas, bays and, rarely high cliffs. In the north, there are pebble beaches and beautiful skerry coasts, composed of small islands formed as a result flooding of hilly glacial land.

Different types of Baltic coasts: sandy beaches, cliffs, skerry coast.

The average depth of the Baltic Sea is only 52 m, so it is a very shallow sea. Its deepest points: Landsort Deep - 459 m, Erland Depth - 405 m, Bothnian Deep - 294 m, Gotland Deep - 250 m, Gdańsk Deep - 118 m. Read more about the Baltic HERE.
