McMurdo Station
The McMurdo Station is a United States Antarctic research center on the south tip of Ross Island, which is in the New Zealand-claimed Ross Dependency on the shore of McMurdo Sound in Antarctica. It is operated by the United States through the United States Antarctic Program, a branch of the National Science Foundation. The station is the largest community in Antarctica, capable of supporting up to 1,258 residents, and serves as one of three United States Antarctic science facilities. All personnel and cargo going to or coming from Amundsen–Scott South Pole Station first pass through McMurdo.
Argentine Antarctic Program
Argentina’s scientific activities started at the beginning of the twentieth century when an Argentine named José María Sobral joined the Swedish South Polar Expedition (1901–1904) commanded by Otto Nordenskjold, which wintered two years in Antarctica. In 1904, W. S. Bruce, leader of the Scottish National Antarctic Expedition, turned over to Argentina the meteorological and geomagnetic observatory on Laurie Island, South Orkney Island which had been established in the previous year. Since then the observatory has been run by Argentina and is the location of the Orcadas Station. It claims to be the first permanent facility south of 60° Southern latitude.
