A new fossil found in the Dry Valleys in the eastern regions of Antarctica, known to have lived some 14 million years ago in an ancient lake, now provides scientists with new evidence that indeed the south polar region of the planet was much warmer in the past. The fossil is a class of crustacea known as ostracods an... |

The attention shifts again from the Arctic ice sheet to Antarctica as the European Space Agency's Envisat satellite showed how over the past month or so, a large ice sheet stretching between the Charcot and Latady Islands in the Antarctic Peninsula, known as the Wilkins Ice Shelf, started to break up again, for ... |

The CryoSat Validation Experiment 2008 will be carried out during a period of three weeks in the northern regions of Greenland and Canada by ESA scientists from Denmark, UK, Germany and Canada, during which time they will collect data regarding the properties of snow and ice covering both the land and sea regions of ... |

Indeed, DDT has been banned in some countries for more than three decades now, but that doesn't mean that several million tons of toxic chemicals just disappeared into thin air during this time. Instead DDT insecticide has been frozen and stored in the Antarctic glaciers, which by the way are now slowly melting ... |

Squids and their relatives, cuttlefish and octopuses, have the most complex eyes in the invertebrate world, closely resembling in structure the eyes of vertebrates. On top of that, the eyes of these animals are relatively large compared to their size. These things considered, it's no wonder that the examination ... |

It is the first time when an unpiloted Unmanned Autonomous Vehicle is used in the antarctic continent to gather data of the harsh environment. The UAV was developed by a British-German collaboration between the British Antarctic Survey and the Technical University of Braunschweig, and it has completed successfully al... |

The Polar Research Institute of China has completed the installation of the robotic observatory PLATeau only after two weeks from their arrival at the Dome Argus location on the Antarctic continent, the highest point of the Antarctic Plateau. PLATO has been built by the University of New South Wales, in Sydney, and i... |

Under the 3,000 m (10,000 ft) thickness of the Antarctic ice sheet, scientists have found proofs of a spectacular volcanic eruption. This happened under the Pine Island Glacier (in the area of the West Antarctic Ice Sheet) about 2,000 years ago (in 325 B.C.) and the under-ice volcano is still active, having a 'v... |

In the North Pole, the first major victim of the global warming seems to be the polar bear. In Antarctica, the victims could be the Adélie penguins. Their ice-made home is melting, and while the southernmost populations are thriving, most are quickly plummeting.These penguins need the winter sea ice as a platform for... |

In case you ever wanted to visit Antarctica, but you were either too lazy or too comfortable to even check the Internet and the agencies' offers for a trip there, this one's for you. Google Earth has just introduced greater detail of the southernmost continent due to their new high resolution satellite."The... |

Today, Antarctica is a frozen desert. But once, it was covered by a lush tropical vegetation and inhabited by heat-loving dinosaurs. A new research, published in the journal "Acta Palaeontologica Polonica", describes a large dinosaur that wandered across the Antarctica about 190 million years ago, during the early Ju... |

A large iceberg has just split off from Pine Island Glacier in Antarctica. Envisat's Advanced Synthetic Aperture Radar (ASAR) instrument monitored the cleavage of the huge ice mass, 34 km in length and 20 km in width, having an area nearly half the size of Greater London.Icebergs appear due to the action of wind... |

This is not good for life on Earth. The hole in the ozone layer over Antarctica has dropped by 30 % in size in 2007 if we compare it to 2006, as revealed by new data sent by the European Space Agency's Envisat satellite. 0.3 % of the ozone layer mass is lost annually, but fluctuations in its thickness occur thro... |

Do not expect the frozen mammoths found in Siberia to wake up and walk after being defrost. But a team led by Kay Bidle of Rutgers University has managed to bring back to life some fossil bacteria trapped in Antarctic ice at least 100,000 years old. The ancient bacteria started to develop metabolism and to grow when ... |

Antarctica is the continent of the superlatives: the coldest (the record: - 94.5o C), the driest (20 mm annually), the remotest and the highest continent, with an average height of 2,450 m or 8,170 ft (the second highest continent, Asia is just 960 m (3,200 ft) high). The Transantarctic Mountains across the frozen co... |

If you think that the deep cold waters of Antarctica have no life, forget it. A new research of the Antarctic Benthic Deep-Sea Biodiversity Project (ANDEEP) has found over 700 new species in the depths of the Southern Ocean (the Indian, Atlantic, and Pacific Oceans surrounding Antarctica). Amongst the species found ... |

90 % of the ice on Earth is stored in Antarctica, being the Earth's largest amount of freshwater. You can imagine that minimal changes in the ice mass of Antarctica have a deep impact on raising the global sea level. Large quantities of Antarctic molten freshwater shed into the ocean could have a deep impact in ... |

Of the seven continents, Antarctica detains some superlatives: it is the coldest (the record: - 94.5Oc), the driest (20 mm annually), the most remote and the highest continent (average height of 2,450 m or 8,170 ft). Asia is just 960 m (3,200 ft) high, Africa 750 m (2,500 ft), North America 720 m (2,400 ft), South Am... |

Today's Antarctica is the most inhospitable place on Earth: it detains the records of cold, being covered by the largest ice pack of the planet (that harbors 90 % of the ice on Earth), haunted almost all year round by chilly winds. Moreover, it is also the most isolated continent, located at thousands of kilomet... |
