Russian Scientists Confirm Discovery of West Antarctic Oasis, Propose Naming It After Polar Explorer Budretsky

Russian scientific institutions have officially verified the discovery and detailed mapping of a previously unknown geographical feature in West Antarctica: an oasis situated on Cape Burks. Announced on April 4, 2026, the find stems from a comprehensive study of 18 unexamined subglacial lakes within that sector of the continent. Researchers from the St. Petersburg Federal Research Center of the Russian Academy of Sciences (SPC RAS), in collaboration with the Arctic and Antarctic Research Institute (AARI), conducted the analysis that reclassified the area from a mere nunatak to a stable and cohesive natural formation.

The newly identified oasis features a mountainous terrain characterized by the presence of valleys. The ice-free surface area spans approximately 2.2 square kilometers. Scientific records indicate that the average annual air temperature at the site hovers around minus 12 degrees Celsius. Cape Burks, the site of the oasis, was originally mapped in January 1962 by an expedition aboard the USS Glacier and named in honor of Lieutenant Commander Ernest Burks. In 1980, the Soviet Union established the Russkaya station on the same cape, which was later mothballed in 1991 following the dissolution of the USSR.

The oasis ecosystem exhibits remarkable biological diversity, supporting populations of penguins, seals, and Antarctic petrels, which underscores the unique nature of its microclimate. Artem Lapenkov, a junior researcher at SPC RAS, explained that the landscape was reassessed after a thorough investigation into lakes with varying environmental conditions. This scientific methodology highlights the necessity of detailed glaciological and hydrological surveys, drawing parallels to previous studies conducted in the Lake Vostok region.

The AARI Academic Council has put forward a proposal to name the new site "Budretsky Oasis" to honor veteran polar explorer Arnold Bogdanovich Budretsky. Budretsky, a distinguished specialist, led the AARI’s Russian Antarctic Expedition and was decorated with the Order "For Naval Merit." Final approval for the name is expected to come from the Scientific Committee on Antarctic Research (SCAR), the body responsible for international Antarctic nomenclature.

This discovery advances the understanding of climate dynamics and geological processes on the ice sheet, building upon the legacy of Russian polar research that began in 1920. While past research at Lake Vostok yielded insights into life isolated for millions of years, the new find at Cape Burks focuses on surface geomorphology and biodiversity. Confirming the existence of a stable oasis expands the scientific map of Antarctica and serves as a testament to the contributions of the nation's polar researchers.
