Giant marine reptile lived in Antarctic 150 million years ago: scientists

BUENOS AIRES, ARGENTINA: Scientists in Argentina have found the remains of a giant carnivorous marine reptile, or plesiosaur, that lived 150 million years ago in Antarctica. The four-finned reptile, which measured up to 12 meters (13 yards) long, dates from the late Jurassic period and is the most ancient creature ever discovered on the continent. Soledad Cavalli, a paleontologist at Argentina's National Scientific and Technical Research Council, said: "At this site, you can find a great diversity of fish, ammonites,…

Warm Antarctic caves harbour secret life: scientists

CANBERRA: A secret world of animals and plants -- including unknown species -- may live in warm caves under Antarctica's glaciers, scientists said on Friday. The caves, hollowed out by steam from active volcanoes, are light and could reach temperatures of 25 degrees Celsius (77 Fahrenheit), researchers said, raising the possibility of a whole ecosystem of flora and fauna deep beneath the frozen surface. A study led by the Australian National University around Mount Erebus, an active volcano on Ross Island in…

Arctic and Antarctic sea ice at record low in January: UN

WASHINGTON: The extent of sea ice in the Arctic and Antarctic last month was the lowest on record for January, the U.N. World Meteorological Organization said on Friday, while concentrations of carbon dioxide in the atmosphere hit a record level. "The missing ice in both poles has been quite extraordinary," David Carlson, Director of the World Climate Research Programme, told a U.N. briefing in Geneva. In 2012, Antarctic sea ice actually hit a record monthly high, with scientists theorizing that melting ice shelves…

Scientists launch unprecedented Antarctic research mission

LONDON: More than 50 researchers from 30 countries are to carry out the first scientific full circumnavigation of Antarctica in an attempt to measure pollution and climate change, with the official launch held on Monday. The international team will cruise on Russian research vessel Akademik Treshnikov, leaving Cape Town on December 20 and returning on March 18 next year, braving hostile conditions in an effort to gain a deeper understanding of humankind's effect on the Southern Ocean. The Antarctic Circumpolar Expedition…
