Underwater Life, White Sea

The important port of Arkhangelsk is located on the White Sea. For much of Russia's history this was Russia's main centre of international maritime trade, conducted by the so-called Pomors ("seaside settlers") from Kholmogory. In the modern era it became an important Soviet naval and submarine base. The White Sea-Baltic Canal connects the White Sea with the Baltic Sea.
The whole of the White Sea is under Russian sovereignty and considered to be internal waters of Russia.
