Colonization of Antarctica is the establishing and maintaining of control over Antarctic land for exploitation and possibly settlement. [1]

Contents

Antarctica was claimed by several states since the 16th century, culminating in a territorial competition in the first half of the 20th century when its interior was explored and the first Antarctic camps and bases were set up. [2]

Contemporarily territorial claims and activities on Antarctica have been limited since the Antarctic Treaty (1959) by the Antarctic Treaty System and its Protocol on Environmental Protection to the Antarctic Treaty. [3]

At present the population of Antarctica comprises scientists and staff of approximate 4,000 people in summer and 1,000 in winter, from 30 countries staying at about 70 bases (40 year-round and 30 summer-only). Of those bases, two are civilian settlements, [4] [5] the Argentinian-administered Esperanza Base and Chilean-administered Villa Las Estrellas.

History

The Antarctic region has been a region of sovereign claims since at least the 16th century. The harsh Southern Ocean thwarted exploration of the region for hundreds of years, until the first half of the 19th century when sealers and explorers reported having found new southern lands. After whalers started hunting in the area polar explorers started venturing inland at the start of the 20th century, reaching the South Pole in 1911, European and American states increasingly made claims over Antartic lands, supported by setting up expanding whaling stations and Antarctic research bases.

Settlement concepts

An idea in the 1950s was to have Antarctic cities enclosed under glass domes. Power and temperature regulation of the domes would come from atomic driven generators outside of these domes. While the Soviets used radioisotope thermal generators in some of their remote Arctic and Antarctic locations, [6] the Americans experimented with nuclear fission, building on their Army nuclear power plant program. The PM-3A nuclear power reactor at McMurdo Station was plagued with reliability issues (achieving an availability factor of only 74%) [7] and was eventually deemed a pollution hazard and consequently shut down and dismantled. [8]

Buckminster Fuller, the developer of the geodesic dome, had raised the possibility of Antarctic domed cities that would allow a controlled climate and buildings erected under the dome. [9] His first specific published proposal for a domed city in 1965 discussed the Antarctic as a likely first location for such a project. [10] The second base at Amundsen–Scott South Pole Station (operated 1975–2003) resembles a reduced version of this idea; it is large enough to cover only a few scientific buildings.

In 1971, a team led by German architect Frei Otto made a feasibility study for an air-supported city dome two kilometers across that could house 40,000 residents. [11] Some authors have recently tried to update the idea. [12]

In 2023 a research report from an Australian team [14] found that the pollution left by international research stations was comparable to that seen in some of the busiest ports in the world.

Although today Antarctica's environment is very harsh, conditions may become better in the future. It has been suggested that, as a result of long-term effects of global warming, the beginning of the 22nd century will see parts of West Antarctica experiencing similar climate conditions to those found today in Alaska and Northern Scandinavia. [15] Even farming and crop growing could be possible in some of the most northerly areas of Antarctica.

It is suggested that plants and fungi find a favorable environment around Antarctica's volcanoes to grow, a hint as to where the first agricultural efforts could be led. [16] There are about 110 native species of moss in Antarctica, and two angiosperms ( Deschampsia antarctica and Colobanthus quitensis ). It is believed those native species will disappear with warmer weather and the arrival of stronger species. Humans are responsible for the introduction of 200 to 300 outside species on the continent. [17]

Recently scientific surveys of an area near the South Pole have revealed high geothermal heat seeping up to the surface from below. [18] [19]

Births and deaths on Antarctica

The population of Antarctica

  All-year active research stations (78.61%)
  Summer-only active research stations (16.15%)
  All-civilian bases (5.24%)

The oldest known case of a person having died on Antarctic land is from the first half of the 19th century. The person was probably a South American indigenous woman, possibly travelling as a guide for early northern Sealers. Her bones were found in the 1980s on a beach on Livingston Island (South Shetlands) off the Antarctic Peninsula. [20]

Emilio Marcos Palma (born January 7, 1978) is an Argentine citizen who is the first person known to be born on the continent of Antarctica. He was born in Fortín Sargento Cabral at the Esperanza Base near the tip of the Antarctic Peninsula and weighed 3.4 kg (7 lb 8 oz). Since his birth, about ten others have been born on the continent.

The Antarctic Treaty and related agreements, collectively known as the Antarctic Treaty System (ATS), regulate international relations with respect to Antarctica, Earth's only continent without a native human population. It was the first arms control agreement established during the Cold War, designating the continent as a scientific preserve, establishing freedom of scientific investigation, and banning military activity; for the purposes of the treaty system, Antarctica is defined as all the land and ice shelves south of 60°S latitude. Since September 2004, the Antarctic Treaty Secretariat, which implements the treaty system, is headquartered in Buenos Aires, Argentina.

It is operated by the United States through the United States Antarctic Program (USAP), a branch of the National Science Foundation. The station is the largest community in Antarctica, capable of supporting up to 1,500 residents, and serves as one of three year-round United States Antarctic science facilities. All personnel and cargo going to or coming from Amundsen–Scott South Pole Station first pass through McMurdo. McMurdo Station continues to operate as the hub for American activities on the Antarctic continent. By road, McMurdo is 3 kilometres (1.9 mi) from New Zealand's smaller Scott Base.

World Park Base was a non-governmental year-round Antarctic base located at Cape Evans on Ross Island in the Ross Dependency. The international environmental organization Greenpeace established World Park Base in 1987 in order to press its demand for the Antarctic Treaty nations to declare the continent of Antarctica as a World Park. This would make the entire continent off-limits to commercial exploitation and pollution, and permit only limited scientific research. Greenpeace closed down in 1991 and completely dismantled the base in 1992.

Seven sovereign states – Argentina, Australia, Chile, France, New Zealand, Norway, and the United Kingdom – have made eight territorial claims in Antarctica. These countries have tended to place their Antarctic scientific observation and study facilities within their respective claimed territories; however, a number of such facilities are located outside of the area claimed by their respective countries of operation, and countries without claims such as China, India, Italy, Japan, Pakistan, Russia, South Africa (SANAE), Poland, and the United States have constructed research facilities within the areas claimed by other countries. There are overlaps among the territories claimed by Argentina, Chile, and the United Kingdom.

It borders the claimed British Antarctic Territory 20° west and the Australian Antarctic Territory 45° east. In addition, a small unclaimed area from 1939 was annexed in June 2015. Positioned in East Antarctica, it makes out about one-fifth of the continent, and is named after the Norwegian Queen Maud (1869–1938).

<span class="mw-page-title-main">Women in Antarctica</span>

There may have been women in Antarctica, exploring the regions around Antarctica for many centuries. The most celebrated "first" for women was in 1935 when Caroline Mikkelsen became the first woman to set foot on one of Antarctica's islands. Early male explorers, such as Richard Byrd, named areas of Antarctica after wives and female heads of state. As Antarctica moved from a place of exploration and conquest to a scientific frontier, women worked to be included in the sciences. The first countries to have female scientists working in Antarctica were the Soviet Union, South Africa and Argentina.
