Antarctica, on average, is the coldest, driest, and windiest continent, and has the highest average elevation of all the continents.[7] Most of Antarctica is a polar desert, with annual precipitation of 200 mm (7.9 in) along the coast and far less inland; yet 80% of the world freshwater reserves are stored there, enough to raise global sea levels by about 60 metres (200 ft) if all of it were to melt.[8][6] The temperature in Antarctica has dropped to −89.2 °C (−128.6 °F) (or even −94.7 °C (−135.8 °F) as measured from space[9]), though the average for the third quarter (the coldest part of the year) is −63 °C (−81 °F). Organisms native to Antarctica include many types of algae, bacteria, fungi, plants, protista, and certain animals, such as mites, nematodes, penguins, seals and tardigrades. Vegetation, where it occurs, is tundra.
Antarctica was the last region on Earth to be discovered, unseen until 1820 when the Russian expedition of Fabian Gottlieb von Bellingshausen and Mikhail Lazarev on Vostok and Mirny sighted the Fimbul ice shelf. The continent remained largely neglected for the rest of the 19th century because of its harsh environment, lack of easily accessible resources, and isolation. In January 1840, land at Antarctica was discovered for the first time, almost simultaneously, by the United States Exploring Expedition, under Lieut. Charles Wilkes, and a separate French expedition under Jules Dumont d'Urville. The latter made a temporary landing; while the Wilkes expedition, though it did not make a landing, did remain long enough in the region to survey and map some 800 miles of the continent. The first confirmed landing was by a team of Norwegians in 1895.
