It is situated in the southern hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by ocean all around i.e. the Southern Ocean. The nearest land mass is South America at 965 km. Its area is close to 14 Million sq km, which is approximately 58 times the size of UK or 1.4 times the size USA. of It is the fifth largest continent after Asia, Africa, North America and South America. On average, Antarctica is the coldest, driest and windiest continent, and has the highest average elevation of all the continents. The minimum recorded surface temperature on the planet i.e. -89.2C was made at the Russian research Vostok in Antarctica on 21st July 1983. 98 % of the total area of Antarctica is covered by ice.The mean thickness of the ice sheet is 1829m and the maximum thickness has been found out to be 4776m. While most of the ice in East Antarctica is on bed rock, in West Antarctica a majority of it floats on water. Due to accumulation of ice over the past millions of years, the continent has got depressed by about 600 m on average. Since there is little precipitation, except at the coasts, the interior of the continent is technically the largest desert in the world. There are no permanent human residents and there is no evidence of any existing or pre-historic indigenous population. Only cold-adapted plants and animals survive there, including mosses and lichen, and several species of penguin, ice seal and the Antarctic fur seal. edit   Selected article The South Pole, also known as the Geographic South Pole or Terrestrial South Pole, is the southernmost point on the surface of the Earth. It lies on the continent of Antarctica. For most purposes, the Geographic South Pole is defined as the southern point of the two points where the earth's axis of rotation intersects its surface (the other being the Geographic North Pole). The Geographic South Pole is marked by a small sign and a stake in the ice pack, which are repositioned each year on New Year’s Day to compensate for the movement of the ice. The Ceremonial South Pole is an area set aside for photo opportunities at the South Pole Station. It is located a short distance from the Geographic South Pole, and consists of a metallic sphere on a plinth, surrounded by the flags of the Antarctic Treaty signatory states. The ceremonial marker is moved every two to three years to keep the walking distance to the Geographical South Pole minimal. edit   Selected picture The Emperor Penguin (Aptenodytes forsteri) is the tallest and heaviest of all living penguin species and is endemic to Antarctica. The species breeds in the coldest environment of any bird species; air temperatures may reach −40 °C (−40 °F), and wind speeds may reach 144 km/h (89 mph). Water temperature is a frigid −1.8 °C (30 °F). edit   Selected panorama Four US Air Force Lockheed LC-130 Hercules at Williams Field, Antarctica. edit   WikiProjects WikiProject Antarctica edit   Things to do Research, review, and add more articles to the Selected Articles section from Category:Antarctica. Improve the completeness and style of the portal Intro subpage. Upload new appropriately-licensed, Antarctica-related pictures and other media. We are looking for more high-quality Selected Articles on Antarctic plants and animals and on the exploration of the continent. We need active peer review and editorial help in the drive to improve Portal:Antarctica to Featured Portal status! Be bold with the graphic design of the portal.
