Making water in the Antarctic desert Home News and media 2020 Making water in the Antarctic desert. In 1969, a Japanese expedition discovered nine meteorites. [179] Models also suggest that the ozone depletion/enhanced polar vortex effect also accounts for the recent increase in sea ice just offshore of the continent. Those features can also be observed in algae and cyanobacteria, suggesting that these are adaptations to the conditions prevailing in Antarctica. [170] Between 28 February and 8 March 2008, about 570 km2 (220 sq mi) of ice from the Wilkins Ice Shelf on the southwest part of the peninsula collapsed, putting the remaining 15,000 km2 (5,800 sq mi) of the ice shelf at risk. This happened three days before Bransfield sighted the land of the Trinity Peninsula of Antarctica, as opposed to the ice of an ice shelf, and ten months before Palmer did so in November 1820. [125] Argentine–UK relations had previously been damaged throughout 2012 due to disputes over the sovereignty of the nearby Falkland Islands, and the 30th anniversary of the Falklands War. [105] Growth is restricted to a few weeks in the summer. A study by Eric Steig published in 2009 noted for the first time that the continent-wide average surface temperature trend of Antarctica is slightly positive at >0.05 °C (0.09 °F) per decade from 1957 to 2006. [1], The ISO 3166-1 alpha-2 "AQ" is assigned to the entire continent regardless of jurisdiction. On top of this base are coal and various modern rocks, such as sandstones, limestones and shales laid down during the Devonian and Jurassic periods to form the Transantarctic Mountains. [122] The only documented military land manoeuvre has been the small Operation NINETY by the Argentine military in 1965.[123]. [78][79] Sunburn is often a health issue as the snow surface reflects almost all of the ultraviolet light falling on it. The researchers present a complete temperature record from Antarctica's Byrd Station and assert that it "reveals a linear increase in annual temperature between 1958 and 2010 by 2.4±1.2 °C". Managers and other senior officers of the whaling stations often lived together with their families. The first confirmed sightings of this landmass, however, did not take place until as late as the early 19th Century, when Russian, British, and American expeditions separately discovered the continent of Antarctica. Other dormant volcanoes may potentially be active. They proposed instead that a comprehensive regime to protect the Antarctic environment be negotiated in its place.
