Adélie Land
France contributed with Dumont d'Urville Station and Charcot Station in Adélie Land. The ship "Commandant Charcot" of the French Navy spent nine months of 1949/50 at the coast of Adélie Land, performing ionospheric soundings. The US erected the Amundsen–Scott South Pole Station as the first permanent structure directly over the South Pole in January 1957.
