Summary
Highlights
Antarctica is the fourth-largest continent, circular in shape, and centered around the South Pole. It spans over 14 million square kilometers in summer, doubling in winter due to ice expansion. It is a unique land reserved for peaceful purposes, where scientists from various countries collaborate, though its history wasn't always this way.
In the 19th and 20th centuries, economic interests and colonial expansion led to conflicts over Antarctic territories. The devastation of World War II spurred the creation of international agreements, such as the UN in 1945, to prevent future conflicts. The Antarctic Treaty, signed in 1959 and effective in 1961, emerged from negotiations among 12 countries to prevent the Cold War from extending to Antarctica. It committed nations to peaceful administration, international scientific cooperation, and prohibited nuclear weapons and military activities not supporting science.
Early sightings of Antarctica date back to the 18th century, with significant explorations by figures like James Cook and Guillermo Brown. The first permanent presence was established by Argentina in 1904 with a meteorological station. Over the decades, other powers like Great Britain, New Zealand, France, Norway, Australia, Chile, and Argentina began claiming sovereignty over parts of Antarctica, often leading to overlapping claims.
The Antarctic Treaty, signed by 12 original countries and later joined by 33 more, resolved potential conflicts by defining permissible activities. Article 1 states Antarctica is exclusively for peaceful purposes, prohibiting military bases, maneuvers, and weapon testing, allowing military personnel only for scientific support. Article 2 promotes scientific research and cooperation. Article 4 freezes all territorial claims, meaning no new claims can be made, and existing claims are not supported or denied while the treaty is in force.
Beyond the primary treaty, the Antarctic Treaty System includes other agreements like the Convention for the Conservation of Antarctic Seals, the Commission on the Conservation of Antarctic Marine Living Resources, and the Protocol on Environmental Protection. These agreements aim to preserve Antarctica for peaceful purposes and protect its living resources.
Argentina has been highly active in Antarctica since the late 19th century, establishing the first permanent base in 1904. Key Argentinian organizations include the Argentine Antarctic Institute (1951) and the National Antarctic Directorate (1970). Argentina maintains six permanent bases (Orcadas, Marambio, San Martin, Esperanza, Belgrano II) and seven temporary bases. Esperanza Base, founded in 1952, saw the first birth in Antarctica and hosts a permanent population, conducting various scientific investigations.
Antarctica experiences extreme cold, with temperatures ranging from 2 to -50 degrees Celsius, and a record low of -88 degrees Celsius. Summers feature 24-hour daylight, while winters have prolonged darkness. Bases are well-equipped with amenities like heating, libraries, satellite TV, phones, and internet. Supplies arrive annually via icebreakers, including Argentina's Irizar, and Hercules C-130 planes.
The Antarctic Treaty prevented conflicts over territorial claims and the exploitation of natural resources, which would have had severe environmental impacts. The treaty system has safeguarded Antarctica as a global patrimony for future generations, demonstrating that international cooperation can overcome conflicts and foster peace.
