    Researchers recently uncovered a startling phenomenon — a set of teardrop-shaped lakes in Antarctica that mysteriously move, jogging along at a pace as fast as 5 feet (1.5 meters) per day. The lakes sit atop the George VI ice shelf — a massive floating plain of ice larger than Vermont, composed of the mingled fronts of glaciers that flow off the edge of the continent and rest on the ocean. Glaciologist Doug MacAyeal at the University of Chicago, and student researcher C.H. LaBarbera, noticed the traveling bodies of water while studying satellite images of 11 ice shelf lakes captured between...

    Thirty-six athletes from 17 countries braved the sub-zero temperatures to complete the 26-mile race at the bottom of the world. The start line for the race was at the Union Glacier Antarctic base camp in the southern Ellsworth Mountains, just over 60 miles from the South Pole. Ahead of the race, every competitor had to have their skin fully protected from the sub-zero temperatures. Clothing included a full balaclava, goggles, gloves and mittens, long johns, waterproof running trousers and several layers of thermal clothing. But the harsh conditions are all part of the appeal of the race. "I guess there's...

    A bizarre underwater "icicle of death" has been filmed by a BBC crew. With time lapse cameras, specialists recorded salt water being excluded from the sea ice and sinking. The temperature of this sinking brine, which was well below 0C, caused the water to freeze in an icy sheath around it. Where the so-called "brinicle" met the sea bed, a web of ice formed that froze everything it touched, including sea urchins and starfish....

    The science journal Nature is making headlines this week with news of the largest hole in the ozone layer over the North Pole in history, rivaling the size of its well known Antarctic cousin. Researchers credit this "unprecedented Arctic ozone loss" to "unusually long-lasting cold conditions" in the stratosphere at a time when their colleagues are in turmoil over melting Arctic sea ice a few miles below, supposedly caused by man-made global warming. Of course, humans are also responsible for the chilly stratosphere, they say. With sky-is-falling overtones the article's authors warn, "We cannot at present predict when such severe...

    A major Antarctic glacier has passed its tipping point, according to a new modelling study. After losing increasing amounts of ice over the past decades, it is poised to collapse in a catastrophe that could raise global sea levels by 24 centimetres. Pine Island glacier (PIG) is one of many at the fringes of the West Antarctic ice sheet. In 2004, satellite observations showed that it had started to thin, and that ice was flowing into the Amundsen Sea 25 per cent faster than it had 30 years before. Now, the first study to model changes in the ice sheet...

    No. We came out of a 'little ice age' around 1850 and the temperature has increased slightly due to this, but nothing abnormal is happening. Global warming alarmists will tell you the polar caps are melting. This isn't exactly true. The University of Illinois keeps the sea ice data. As you can see from the chart below, Arctic ice is decreasing. However, Antarctic ice is currently increasing. When you combine the two charts into a global sea ice chart, you can see sea ice has been very stable for the last 150 years.

However, the study published in the journal Science found that even a one meter rise in sea levels would be significant enough to weaken the Earth's gravity field in the southern hemisphere and...

The West Antarctic ice sheet collapsed periodically between 3 million and 5 million years ago, adding more than 16 feet to global sea level, according to the first examination of soil cores far below the surface of the Ross ice shelf. Also, new computer models suggest that warmer waters nearby attacked the ice from below, triggering those collapses. Both findings appear in studies published Thursday in the journal Nature.

    Spinning a "mucus net" off its paddle-like foot-wings to trap algae and other foods, the swimming snail species Limacina helicinia is no bigger than a bean. But the discovery that it and at least 234 other species inhabit both Arctic and Antarctic waters is big news to biologists.

    WILKINS ICE SHELF, Antarctica (Reuters) - A huge Antarctic ice shelf is on the brink of collapse with just a sliver of ice holding it in place, the latest victim of global warming that is altering maps of the frozen continent. "We've come to the Wilkins Ice Shelf to see its final death throes," David Vaughan, a glaciologist at the British Antarctic Survey (BAS), told Reuters after the first -- and probably last -- plane landed near the narrowest part of the ice. The flat-topped shelf has an area of thousands of square kilometers, jutting 20 meters (65 ft) out...

    Daredevil SAS man-turned-explorer Bear Grylls was being airlifted to South Africa last night after being badly injured filming a TV documentary in Antarctica. The 34-year-old adventurer broke his shoulder in a life-threatening fall and was said to be in ‘shock and agony’ from a serious fracture which left the bone protruding from his body. The accident happened at 11pm British time on Friday, and Bear’s insurance company arranged for his evacuation by air ambulance for urgent medical treatment, at an estimated cost of £60,000.

    A group of isolated Antarctic islands have proved to be unexpectedly rich in life. The first comprehensive biodiversity survey of the South Orkney Islands, near the tip of the Antarctic Peninsula, has revealed that they are home to more species of sea and land animals than the Galapagos.Researchers from the British Antarctic Survey and the University of Hamburg, Germany, carried out the survey using a combination of trawl nets, sampling as deep as 1500m, and scuba divers. The team found over 1200 species, a third of which were not thought to live in the region. They also identified five new...

    Figure of the fossil ostracod from the Dry Valleys. The specimen is less than 1 mm long, but preserves an array of soft tissues including legs and mouth parts. A new fossil discovery- the first of its kind from the whole of the Antarctic continent- provides scientists with new evidence to support the theory that the polar region was once much warmer. The discovery by an international team of scientists is published today (**Embargoed until 00.01 BST Wednesday 23 July**) in Proceedings of the Royal Society B. It involved researchers from the University of Leicester, North Dakota State University,...

    PARIS (AFP) - New evidence has emerged that a large plate of floating ice shelf attached to Antarctica is breaking up, in a troubling sign of global warming, the European Space Agency (ESA) said on Thursday. Images taken by its Envisat remote-sensing satellite show that Wilkins Ice Shelf is "hanging by its last thread" to Charcot Island, one of the plate's key anchors to the Antarctic peninsula, ESA said in a press release. "Since the connection to the island... helps stabilise the ice shelf, it is likely the breakup of the bridge will put the remainder of the ice shelf...

    The newest analysis of trace gases trapped in Antarctic ice cores now provide a reasonable view of greenhouse gas concentrations as much as 800,000 years into the past, and are further confirming the link between greenhouse gas levels and global warming, scientists reported in the journal Nature. They also show that during that entire period of time, there have never been concentrations of carbon dioxide and methane as high as the current levels, said Edward Brook, an associate professor of geosciences at Oregon State University, and author of a Nature commentary on the new studies. "The fundamental conclusion that today's...
  • Cold Water Thrown on Antarctic Warming Predictions

    Antarctica hasn't warmed as much over the last century as climate models had originally predicted, a new study finds. Climate change's effects on Antarctica are of particular interest because of the substantial amount of water locked up in its ice sheets. Should that water begin to melt, sea levels around the globe could rise and inundate low-lying coastal areas. The new study, detailed in the April 5 issue of the journal Geophysical Research Letters, marks the first time that researchers have been able to give a progress report on Antarctic climate model projections by comparing climate records to model simulations...

    A vast ice shelf hanging on by a thin strip looks to be the next chunk to break off from the Antarctic Peninsula, the latest sign of global warming's impact on Earth's southernmost continent. Scientists are shocked by the rapid change of events. Glaciologist Ted Scambos of the University of Colorado was monitoring satellite images of the Wilkins Ice Shelf and spotted a huge iceberg measuring 25 miles by 1.5 miles (41 kilometers by 2.5 kilometers - about 10 times the area of Manhattan) that appeared to have broken away from the shelf. Scambos alerted colleagues at the British Antarctic...

    Krill Discovered Living In The Antarctic AbyssFemale Antarctic krill. Krill have been found living and feeding down to depths of 3,000 meters. (Credit: Image courtesy of British Antarctic Survey) ScienceDaily (Feb. 26, 2008) — Scientists have discovered Antarctic krill (Euphausia superba) living and feeding down to depths of 3000 metres in the waters around the Antarctic Peninsula. Until now this shrimp-like crustacean was thought to live only in the upper ocean. The discovery completely changes scientists' understanding of the major food source for fish, squid, penguins, seals and whales. Reporting recently in Current Biology, scientists from British Antarctic Survey (BAS)...

    Antarctic may hold the future of archaeology Norman Hammond, Archaeology Correspondent It is a truism that archaeology begins yesterday, and now with only the archaeology of the future to plan for, the discipline has been expanding into areas of the globe where material culture has hitherto played little part. Antarctica is one of these new areas: more than two centuries of human occupation have left plentiful traces. At least five successive and partly overlapping phases of activity can be defined: sealing, whaling, polar exploration, scientific investigation and tourism. Sealing began in the late 18th century, when Captain James Cook’s account...
