Demographics of Antarctica
Antarctica has few permanent residents, and contains research stations and field camps that are staffed seasonally or year-round, and former whaling settlements. The largest station, McMurdo Station, has a summer population of about 1,000 people and a winter population of about 200. Approximately 29 nations, all signatory to the Antarctic Treaty, send personnel to perform seasonal (summer) or year-round research on the continent and in its surrounding oceans.
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.
