New data unlocks secrets of Antarctic formation

The link between declining CO2 levels in the earth's atmosphere and the formation of the Antarctic ice caps some 34 million years ago has been confirmed for the first time in a major research study.

Unlikely life thriving at Antarctica's

An unmapped reservoir of briny liquid chemically similar to sea water, but hidden under an inland Antarctic glacier, appears to support microbial life in a cold, dark, oxygen-poor environment – a most unexpected setting to be teeming with life.

Scientists publish first ever evidence of asteroids with earth-like crust

Two rare meteorites found in Antarctica two years ago are from a previously unknown, ancient asteroid with an outer layer or crust similar in composition to the crust of Earth's continents, reports a research team primarily composed of geochemists from the University of Maryland.

Market visiting rights to Antarctica

Tourism on Antarctica is increasing and that can form a threat for the vulnerable South Pole area. Research from Maastricht University provides a possible solution: market the visitor rights to the highest bidder.

Antarctica and North America were once connected

The first Australian map of the entire Antarctica has become part of the National Archives collection.

Scientists find 245-million-year-old burrows of land vertebrates in Antarctica

For the first time paleontologists have found fossilized burrows of tetrapods – any land vertebrates with four legs or leglike appendages – in Antarctica dating from the Early Triassic epoch, about 245 million years ago.

Climate models overheat Antarctica

Computer analyses of global climate have consistently overstated warming in Antarctica, concludes new research by scientists at the National Center for Atmospheric Research (NCAR) and Ohio State University. The study can help scientists improve computer models and determine if Earth's southernmost continent will warm significantly this century, a major research question because of Antarctica's potential impact on global sea-level rise.

Unmanned aerial vehicles mark robotic first for British Antarctic Survey

harminka — Wed, 19 Mar 2008 11:32:43 -0500

Scientists at British Antarctic Survey (BAS) in collaboration with the Technical University of Braunschweig (TUBS), Germany have completed the first ever series of flights by autonomous unmanned aerial vehicles (UAVs) in Antarctica. This is the first time that unpiloted UAVs have been used in the Antarctic and the successful flights open up a major new technique for gathering scientific data in the harshest and remotest environment on Earth.

Observing sustainable tourism in Antarctica

“Antarctica is the ultimate destination for anyone interested in natural history but it also challenges those people who visit to think broadly about our responsibilities to all life on Earth.”

Scientists Say Wondrous New Species Found Off Antarctica

Scientists say they have taken an array of new marine species from the seabed off eastern Antarctica. They are warning, though, that climate change could soon make extinct many of the strange creatures they have just discovered. From Sydney, Phil Mercer reports.

“Antarctica is the ultimate destination for anyone interested in natural history but it also challenges those people who visit to think broadly about our responsibilities to all life on Earth.” That's the view of Dr Robert Lambert, a lecturer on Tourism and the Environment at The University of Nottingham, who has just returned from the Antarctic in his role as an Observer for the International Association of Antarctica Tour Operators (IAATO).
