Argentine Antarctica (Spanish: Antártida Argentina) is a sector of Antarctica claimed by Argentina as part of its national territory. The Argentine Antarctic region, consisting of the Antarctic Peninsula and a triangular section extending to the South Pole, is delimited by the 25° West and 74° West meridians and the 60° South parallel. Administratively, Argentine Antarctica is a department of the province of Tierra del Fuego, Antarctica, and South Atlantic Islands. The provincial authorities reside in Ushuaia and the Governor annually designates his or her delegate for the Antarctica region. The "civil power" of any of the administrators extends no further than that nation's own bases. The Argentine exploration to the continent started early in the 20th century. José María Sobral was the first Argentine to set foot on Antarctica in 1901, where he spent 2 seasons with the Swedish Antarctic Expedition of Doctor Otto Nordenskiöld. Shortly afterwards, in 1904, the Orcadas permanent base was already fully operational. Years later other bases would be created, some permanent and others seasonal. The first Argentine expedition to reach the South Pole was the 1965 Operación 90. Argentine actions in Antarctica are coordinated by the Instituto Antartico Argentino --------- According the last Argentine national census, on October 2010 (winter) there were 230 habitants in the six permament bases, including 9 families and 16 children as follow: 75 at Marambio, 66 at Esperanza, 33 at Jubany, 20 at San Martín, 19 at Belgrano II and 17 at Orcadas.
