About Baltic Sea:

  • It is a semi-enclosed inland sea located in Northern Europe.
  • It is an arm of the North Atlantic Ocean, extending northward from the latitude of southern Denmark almost to the Arctic Circle and separating the Scandinavian Peninsula from the rest of continental Europe.
  • It has a coastline of approximately 8,000 km, shared by several countries, including Sweden, Poland, Lithuania, Latvia, Finland, Estonia, Germany, Denmark, and Russia.
  • It covers an area of approximately 377,000 sq.km. The sea is approximately 1,600 km long and 193 km wide.
  • It is connected to the White Sea via the White Sea Canal and to the North Sea’s German Bight via the Kiel Canal.
  • It connects to the Atlantic Ocean through the Danish Straits.
  • The Baltic Sea contains three major gulfs: the Gulf of Bothnia to the north, the Gulf of Finland to the east, and the Gulf of Riga slightly to the south of that.
  • It is often cited as the world’s largest brackish inland water body.
  • Its water salinity levels are lower than that of the World Oceans due to the inflow of fresh water from the surrounding land and the sea’s shallowness.
