Polar regions of Earth
The southern polar region has no permanent human habitation. McMurdo Station is the largest research station in Antarctica, run by the United States. Other notable stations include Palmer Station and Amundsen–Scott South Pole Station (United States), Esperanza Base and Marambio Base (Argentina), Scott Base (New Zealand), and Vostok Station (Russia).
A. B. Dobrowolski Polar Station
The research station was built by the Soviet Antarctic Expedition in 1956 and named "Oazis" (Оазис, ). The station was handed over by the Soviet Academy of Sciences to the Polish Academy of Sciences in January 1959. It was manned briefly by the Polish expedition, which carried out a number of studies, primarily in the fields of gravimetry and geomorphology. The station has not been used regularly since, due to the lack of funds and the high costs of air transport, and there are no plans to reopen the station as a permanent institution. The station has been visited periodically by Polish and other research teams. The last Polish team was reported to have visited the station in the 1960s or 1970s (sources vary). A 1998 Polish statistical yearbook described the base as "periodically active". Official classification of the station is "inactive". The station is only occasionally visited by tourists, such as those who documented their visit in 2010.
