Lagoons by the Baltic Sea, in Poland, Russia and Lithuania
The Baltic Sea is a brackish inland sea located in Northern Europe, bounded by the Scandinavian Peninsula, the mainland of Europe, and the Danish islands.
The close-up focuses on the coasts of Poland (bottom left) and Lithuania (top right), with the Kaliningrad Oblast, an exclave of Russia, between them.
Here, two lagoons can be observed: the Curonian Lagoon and the Vistula Lagoon. Parts of both are covered with snow and ice.
The Curonian Lagoon is separated from the Baltic Sea by the Curonian Spit. At the northern end of the spit, there is a passage to the Baltic Sea.
The Vistula Lagoon is a fresh water lagoon on the Baltic Sea separated from Gdańsk Bay by the Vistula Spit. The lagoon is a mouth of a few branches of the Vistula River, notably the Nogat, and the Pregolya Rivers. It is connected to Gdańsk Bay by the Strait of Baltiysk. Kaliningrad and Baltiysk are currently major seaports on the lagoon.
