Base antarctique Mawson

Mawson Station, commonly called Mawson, is one of three permanent bases and research outposts in Antarctica managed by the Australian Antarctic Division (AAD). Mawson lies in Holme Bay in Mac. Robertson Land, East Antarctica in the Australian Antarctic Territory, a territory claimed by Australia. Established in 1954, Mawson is Australia's oldest Antarctic station and the oldest continuously inhabited Antarctic station south of the Antarctic Circle. It houses approximately 20 personnel over winter and up to 53 in summer. Mawson was named in honour of the Australian Antarctic explorer Sir Douglas Mawson. Mawson was listed on the Register of the National Estate in 2001 and listed on the Commonwealth Heritage List on 22 June 2004, reflecting the post-World War Two revival of Australia's scientific research and territorial interests in Antarctica. Mawson Station is a base for scientific research programs including an underground cosmic ray detector, various long-term meteorological aeronomy and geomagnetic studies, as well as ongoing conservation biology studies, in particular of nearby Auster rookery, a breeding ground for emperor penguins and Adélie penguins. In 1946, the Minister for External Affairs, H.V. Evatt indicated his support for a proposal by Douglas Mawson for the establishment of a permanent Australian base in Antarctica. It was another seven years before a suitable ship, the Kista Dan could be chartered to set up facilities on the southern continent. The station site was chosen in 1953 by Phillip Law, the first director of the AAD, who drew aerial photographs taken during the U.S. Operation Highjump (OpHjp) of 1946-1947 to select the site for its large natural harbour (Horseshoe Harbour) and permanently exposed rock for building. The station was built during 1954. Some of the small pre-fabricated huts used in the first years remain on the station, but these are overshadowed by large steel-framed modular buildings dating from a major rebuilding program that started in the late 1970s.
