The book "On the Student Seas" tells about the history of Russian polar navigation in the period XII-XVIII centuries. The author sought to show how important ancient navigation was in the knowledge of the Arctic Ocean and what contribution belongs to generations of unknown Pomor heroes in the study of the northern seas. The book tells how in the X-XI centuries. Novgorodians reached the Student (White) Sea and created settlements on its shores. Pomor immigrants began to master the riches of the Arctic: sea beast, furs, fish. This served as an incentive for the development of Arctic navigation. Gradually, Pomors created special designs of sea vessels - lodges, kochi, which at that time were the best types of ships for sailing in ice. On these ships, Pomors penetrated further and further north, opened the Arctic islands and unknown shores of the Arctic Ocean. The author believes that Pomors long before the campaign of S.I. Dezhnev and F.A. Popova reached the extreme northeastern limits of Asia and penetrated into Northwest America, where they founded their settlements.
