The seabed of the central part and Dvina Bay is covered in silt and sand. The bottom of the northern part, the Kandalaksha Gulf and Onega Bay is a mixture of sand and stones.
The White Sea has a large number of islands, but most of them are small. The main island group is the Solovetsky Islands. They are almost in the middle of the sea, near the entrance to Onega Bay. Kiy Island in Onega Bay is important due to a historic monastery. Velikiy Island, close to the shore, is the largest island in the Kandalaksha Gulf.
The sea has more than 700 species of invertebrates, about 60 species of fish, and 5 species of marine mammals. The fishing industry is small. They mostly target harp seal, ringed seal, herring, saffron cod, European smelt, Atlantic cod and Atlantic salmon. There is a developing seaweed industry.
The White Sea is an important traffic centre of northwestern Russia. The White Sea – Baltic Canal links it through Onega Lake to the Baltic Sea and the major city and port of Saint Petersburg. The Baltic Sea, in turn, is connected by the Volga–Baltic Waterway to the Volga River, Black, Caspian, and Azov seas. The major ports on the White Sea are Arkhangelsk, Belomorsk, Onega, Mezen, Kem, Kandalaksha and Umba. Even though it is frozen in winter, boats can travel on the sea all year around because of the use of icebreakers.

Guglielmo Marconi
Guglielmo Marconi (25 April 1874 20 July 1937) was an Italian inventor and electrical engineer. He was a pioneer of long-distance radio transmission. which he used to build up a radio telegraph system. Marconi is often named as the inventor of radio. He shared the 1909 Nobel Prize in Physics with Karl Ferdinand Braun.
Much of Marconi's work in radio transmission was built on previous experimentation, and work by others. When he was twenty years old, he learned of the experiments of Hertz, Popov, Lodge, Bose, and Tesla. He began his own experiments.
As an entrepreneur, businessman, and founder of The Wireless Telegraph & Signal Company in Britain in 1897, Marconi became wealthy in the business of radio, mainly for ships at sea.
