Belkov, Nikolaĭ Semenovich (?–?)
Belkov, Nikolaĭ Semenovich (?–?) – A Russian sailor, Arctic explorer, and Yakut manufacturer. In 1804 discovered salt and oil deposits close to the Khatanga Bay and in 1808 an island in the Laptev Sea (the New Siberian Islands) and named it St. John the Savior Island. Later the participants of the expedition renamed it in honor of the discoverer into Belkovskiy Island. In 1808–1811, he took part in an expedition under the command of M.M. Hedenstrom who was studying the New Siberian Islands. In 1814 he discovered Semenovsky Island and in 1822 Vasilyevsky Island (a different version says that both the islands were discovered in 1815 by a Yakut M. Lyakhov). In 1936 Vasilyevsky Island was not found any more and by 1948 Semenovsky Island also disappeared. They consisted mostly of frozen soil and were destroyed by water.
