A. B. Dobrowolski Polar Station
A.B. Dobrowolski Polar Station (Polish: Stacja im. A.B. Dobrowolskiego) is an inactive Polish polar research station in Antarctica. It is located at the edge of the Algae Lake, Bunger Hills region in the Wilkes Land and was originally constructed by the Soviet Union. It is one of the two Polish stations in Antarctica, the other being the Henryk Arctowski Polish Antarctic Station.
The research station was built by the Soviet Antarctic Expedition in 1956 and named Oazis (Оазис, English: Oasis). 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". As of 2010 the station is only occasionally visited.
The magnetic observatory building, along with a plaque commemorating the establishment of Oasis Station in 1956, has been designated a Historic Site or Monument (HSM 10) following a proposal by Russia to the Antarctic Treaty Consultative Meeting (ATCM). The concrete pillar erected by the Polish expedition to measure acceleration due to gravity has similarly been designated a Historic Site or Monument (HSM 49) following a proposal by Poland to the ATCM.
