Antarctica is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of 14,200,000 km2 (5,500,000 sq mi). Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of 1.9 km (1.2 mi).

The First Russian Antarctic Expedition took place in 1819–1821 under the direction of Fabian Bellingshausen and Mikhail Lazarev. The expedition aimed to reach the Southern Ocean in order to prove or disprove the existence of a suspected seventh continent, Antarctica. The sloop Vostok was under the command of Bellingshausen, while Lazarev commanded the sloop Mirny. Overall, the crew consisted of 190 people.
