Argentina claims a vast, frozen slice of the Antarctic continent as national territory.

In short: Spanning over 1.4 million square kilometers, Argentine Antarctica is a region defined by extreme cold, shifting glaciers, and overlapping international claims. While Argentina maintains a permanent presence through research bases and families, the territory remains a complex geopolitical puzzle governed by the constraints of the Antarctic Treaty.

Argentine Antarctica is a triangular sector stretching from the 60° South parallel to the South Pole, bounded by the 25° and 74° West meridians. This territory, which Argentina administers as a department of its Tierra del Fuego province, covers approximately 1,461,597 square kilometers. Much of the land is buried under ice sheets averaging two kilometers in thickness, creating a harsh environment where temperatures can plummet to -82°C. Despite the severity, the region has hosted permanent human settlements for over a century, beginning with the Orcadas Base in 1904.

The roots of Argentina's claim are deeply tied to early 20th-century exploration and meteorological observation. Following the establishment of the Orcadas Base, the nation gradually formalized its presence, creating the National Antarctic Commission in 1940 and declaring its mainland rights in 1942. This process was marked by intense friction; in the 1950s, territorial disputes led to minor military confrontations, including incidents at Hope Bay and Deception Island where British and Argentine forces exchanged fire or dismantled rival structures. These tensions eventually cooled as both nations rejected the jurisdiction of the International Court of Justice regarding their claims in 1955.

Today, the region operates under the framework of the Antarctic Treaty, which entered into force in 1961. Argentina maintains six permanent stations and several summer bases, supporting a small, fluctuating population that included 130 inhabitants as of the 2022 census. The area is not merely a scientific outpost; it has seen the birth of the first documented person on the continent, Emilio Palma, in 1978. While Argentina continues to assert its sovereignty, its claims overlap significantly with those of the United Kingdom and Chile, ensuring that this frozen frontier remains a site of ongoing diplomatic and geopolitical negotiation.
