what are the 12 countries in antarctica

They proposed instead that a comprehensive regime to protect the Antarctic environment be negotiated in its place. In 1983 the Antarctic Treaty Parties began negotiations on a convention to regulate mining in Antarctica. [68] The ice began to spread, replacing the forests that until then had covered the continent. [1], Although coal, hydrocarbons, iron ore, platinum, copper, chromium, nickel, gold and other minerals have been found, they have not been in large enough quantities to exploit. King penguins, chinstrap penguins, and gentoo penguins also breed in the Antarctic. During the Eocene–Oligocene extinction event about 34 million years ago, CO2 levels have been found to be about 760 ppm[67] and had been decreasing from earlier levels in the thousands of ppm. It is governed and protected by the Antarctic Treaty. Explorer Matthew Flinders, in particular, has been credited with popularising the transfer of the name Terra Australis to Australia. [162][164], Some of Antarctica has been warming up; particularly strong warming has been noted on the Antarctic Peninsula. National Geographic suggests that Argentina, Australia, Chile, France, New Zealand, Norway and the United Kingdom presently claim parts of the continent. In 1895, the first confirmed landing was conducted by a team of Norwegians. A major concern within this committee is the risk to Antarctica from unintentional introduction of non-native species from outside the region. Researchers include biologists, geologists, oceanographers, physicists, astronomers, glaciologists, and meteorologists. East Antarctica is colder than its western counterpart because of its higher elevation. The 30 countries working on Antarctica have imposed strict safety requirements in an attempt to prevent a Covid-19 outbreak on the continent, including significant reductions to … Glaciologists in Antarctica are concerned with the study of the history and dynamics of floating ice, seasonal snow, glaciers, and ice sheets. 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. [64] It was during this era that Gondwana began to break up. The Antarctic Treaty. The ATS was first brought into affect in 1961 with 12 countries signing it – Argentina, Australia, Belgium, Chile, France, Japan, New Zealand, Norway, South Africa, the … [92], Few terrestrial vertebrates live in Antarctica, and those that do are limited to the sub-Antarctic islands. The biggest eruption in Antarctica in the last 10,000 years, the volcanic ash was found deposited on the ice surface under the Hudson Mountains, close to Pine Island Glacier. This is partly offset by autumn cooling in East Antarctica. There is a waterfall in Antarctica, known as the “Blood Falls,” that has a high amount of iron and is … About 98% of Antarctica is covered by the Antarctic ice sheet, a sheet of ice averaging at least 1.6 km (1.0 mi) thick. Antarctic krill, which congregate in large schools, is the keystone species of the ecosystem of the Southern Ocean, and is an important food organism for whales, seals, leopard seals, fur seals, squid, icefish, penguins, albatrosses and many other birds. [131] The 1991 Protocol on Environmental Protection to the Antarctic Treaty also restricts a struggle for resources. [95] The snow petrel is one of only three birds that breed exclusively in Antarctica. Various factors may aid in their distribution – fairly uniform temperatures of the deep ocean at the poles and the equator which differ by no more than 5 °C, and the major current systems or marine conveyor belt which transport eggs and larval stages. However, there are twelve countries that are original signatories to the Antarctic Treaty. 95 % of the whalers were Norwegian, with an increasing proportion of Britons 131.
