Exploration prior to the IAA

José María Sobral, who is considered in Argentina the father of the Argentine Antarctica and a national hero, began exploration at the end of 1901. In 1903, the Argentine Navy corvette ARA Uruguay commanded by Captain de Corbeta (Lieutenant commander) Julián Irízar successfully rescued the Swedish expedition team of Otto Nordenskjöld. In 1904 the Argentine permanent presence in Antarctica began with the opening of Orcadas Base on Laurie Island. Argentina was the only nation to have an Antarctic base for 40 years until the British built a base on the same islands.

On April 1, 1940, the first radio communication by radio hams was made between Orcadas Base (LSX) and Buenos Aires (LU 7 ET).

On February 7, 1942, an amphibious Stearman aircraft embarked on the ARA 1 de Mayo cargo ship made the first Argentine flight over Antarctica.

On December 13, 1947, an Argentine Naval Aviation Douglas DC-4 piloted by Comodoro Gregorio Portillo flew over the Antarctic Circle in a 15 hours and 30 minutes flight.

Formation

On 17 April 1951, Hernán Pujato founds the Instituto Antartico Argentino, by Decree Nº 7338. In 1953 the San Martín Base started operations, and Jubany base opened two years later.

In 1958 the United States handed over the Ellsworth Station located in the Weddell Sea. In 1965 the Argentine military conducted a land military manoeuvre known as Operación 90 in order to reach the South Pole.

In the winter of 1968 at the request by the British embassy in Buenos Aires, an Argentine Navy Douglas DC-4 successfully delivered medical supplies to the British base EFE where one of its members, James K. Portwirie, was through a medical emergency. However, after a few days, Portwirie's situation worsened, making a rescue necessary. An Argentine Air Force aircraft attempted to reach the base but crashed without casualties. On August 9, in the middle of the Antarctic winter, the Argentine Navy icebreaker ARA General San Martín was sent to rescue Portwirie. The operation was successful, gaining the thanks of the British Antarctic Survey: ‘‘an internal campaign like this was never attempted before in Antarctic History‘‘.^[3]

Marambio Base was founded in 1969, currently the most important Argentine base on the Antarctica. In 1975 the Esperanza Base was built, and in 1979 the General Belgrano II. In 1978, the first Antarctic baby, Emilio Palma, was born in the Fortín Sargento Cabral at the Esperanza Base.

Twenty-first century

In 2002, the Argentine Navy mounted an internal operation sending the icebreaker ARA Almirante Irizar to rescue the trapped supply vessel Magdalena Oldendorff. Even though Irízar failed to break the Oldendorff free, she managed to move it to a safe position and re-supply the ship with food, medicines and medical personnel until the ice melted and the ship could return to open sea.

In 2003, under the Decree Nº 207/2003 issued by the Executive Power of Argentina, the Instituto Antártico Argentino became a part of the Ministry of Foreign Affairs

On the 2009 summer campaign, the Argentine Air Force operated the Teniente Matienzo Base only with women for three months ^[4][5] although there was an emergency link available with the Bell 212s helicopters stationed at Marambio Base

On 2010 a wind turbine designed and built by Argentine government company CITEDEF was installed on Marambio Base ^[6]

On 2011, three heavy lift helicopters were deployed in the Base Marambio: two Mil Mi 17 helicopters (bought in the same year), and the remaining Chinook from the Argentine Air Force.
