Knowra British Antarctic Survey British Antarctic Survey The United Kingdom’s national polar research organization, conducting scientific research and operating research stations, ships, and aircraft in Antarctica and the Southern Ocean.
Antarctic ozone hole : A seasonal thinning of stratospheric ozone over Antarctica, first identified in the 1980s. BAS scientists’ measurements at Halley Research Station revealed the ozone decline.
Halley Research Station : A British Antarctic research station on the Brunt Ice Shelf, rebuilt and relocated as the ice changes. It is BAS’s flagship platform for atmospheric and space-weather research.
Discovery Investigations : British scientific expeditions studying whales and ocean conditions in the Southern Ocean from the 1920s onward. Their work established a research tradition that BAS inherited and expanded.
Joseph Farman : A British atmospheric scientist whose Antarctic ozone measurements helped reveal the ozone hole. His BAS team reported the dramatic springtime ozone decline in 1985.
Antarctic ice sheet : The vast mass of glacial ice covering most of Antarctica. BAS research tracks how its ice flow and melting affect global sea levels.
Rothera Research Station : The largest British Antarctic research station, located on Adelaide Island in the Antarctic Peninsula. It supports BAS science, aircraft operations, and access to the Antarctic Peninsula.
Operation Tabarin : A secret British wartime expedition, begun in 1943, that established permanent bases in Antarctica. Its stations and scientific program became the foundation of Britain’s postwar polar presence.
Brian Roberts : A British polar scientist and administrator who helped establish postwar Antarctic research institutions. He led the transition from wartime bases to an organized national science program.
Southern Ocean : The ocean encircling Antarctica, defined by the Antarctic Circumpolar Current and its polar waters. BAS ships and field teams study its circulation, ecosystems, and role in climate.
RRS Sir David Attenborough : A British polar research vessel commissioned in 2021 for science and logistical support. The ship extends BAS research into remote waters and supports Antarctic stations.
