Antarctic ice shelf disintegrating as result of climate change, say scientists
Satellite imagery from the University of Colorado at Boulder's National Snow and Ice Data Center shows a portion of Antarctica's massive Wilkins Ice Shelf has begun to collapse because of rapid climate change in a fast-warming region of the continent. view more (2008-03-26)
Threat from West Antarctica less than previously believed
The potential contribution to sea level rise from a collapse of the West Antarctic Ice Sheet (WAIS) have been greatly overestimated, according to a new study published in the journal Science. view more (2009-05-15)
Melting threat from West Antarctic Ice Sheet may be less than expected, could hit US hardest
While a total or partial collapse of the West Antarctic Ice Sheet as a result of warming would not raise global sea levels as high as some predict, levels on the U.S. seaboards would rise 25 percent more than the global average and threaten cities like New York, Washington, D.C., and San Francisco, according to a new study. view more (2009-05-15)
UK robot sub searches for signs of melting 60 km into an Antarctic ice shelf cavity
Autosub, a robot submarine built and developed by the UK's National Oceanography Centre, Southampton, has successfully completed a high-risk campaign of six missions travelling under an Antarctic glacier. view more (2009-03-18)
Mission to Mars via Antarctica
As part of the Aurora Exploration Programme, ESA is considering participating in a human mission to Mars by the year 2030. view more (2005-12-21)
Tuatara, the fastest evolving animal
In a study of New Zealand's "living dinosaur" the tuatara, evolutionary biologist, and ancient DNA expert, Professor David Lambert and his team from the Allan Wilson Centre for Molecular Ecology and Evolution recovered DNA sequences from the bones of ancient tuatara, which are up to 8000 years old. view more (2008-03-24)
Texas researchers and educators head for Antarctica
It's been more than 100 years since anyone has journeyed to this section of Antarctica's Amundsen Sea, but that is about to change. view more (2007-08-16)
Map characterizes active lakes below Antarctic ice
Lakes in Antarctica, concealed under miles of ice, require scientists to come up with creative ways to identify and analyze these hidden features. view more (2009-09-02)
Giant Neutrino Telescope Takes Shape - Important Milestone for the International IceCube Project
A key first step has been taken in the construction of IceCube, a giant neutrino telescope spanning a volume of one cubic kilometer of ice at the South Pole: Working under harsh Antarctic conditions, an international team of scientists, engineers and technicians - among them scientists from the DESY research center - has successfully deployed a... view more...

Wilkins Ice Shelf hanging by its last thread
The Wilkins Ice Shelf is experiencing further disintegration that is threatening the collapse of the ice bridge connecting the shelf to Charcot Island. Since the connection to the island in the image centre helps to stabilise the ice shelf, it is likely the break-up of the bridge will put the remainder of the ice shelf at risk. view more (2008-07-11)
Climate kick from the Southern Ocean
This much was already known: in the closing phase of the last ice age the Southern Hemisphere began warming first. As a result, the Antarctic sea ice melted. It was at least a thousand years later - as evidenced by investigations of Greenland ice cores - that the high northern latitudes began to get warmer. Sea ice in the North Atlantic retreated... view more... (2003-07-29)
ESA keeps vigil on the Antarctic ice pack
An unusually heavy Antarctic sea-ice pack has kept polar supply ship Magdalena Oldendorff trapped for more than a month. A multinational rescue mission already evacuated passengers and non-essential crew from the vessel, caught in ice while returning from the Russian base of Novolazarevskaya on Queen Maud Land. Meanwhile, an Argentine icebreaker... view more... (2002-07-19)
Peering under the ice of a collapsing polar coast
Starting this month, a giant NASA DC-8 aircraft loaded with geophysical instruments and scientists will buzz at low level over the coasts of West Antarctica, where ice sheets are collapsing at a pace far beyond what scientists expected a few years ago. view more (2009-10-08)
NASA's AURA satellite peers into Earth's ozone hole
NASA researchers, using data from the agency's AURA satellite, determined the seasonal ozone hole that developed over Antarctica this year is smaller than in previous years. view more (2005-12-07)
Algae and pollen grains provide evidence of remarkably warm period in Antarctica's history
For Sophie Warny, LSU assistant professor of geology and geophysics and curator at the LSU Museum of Natural Science, years of patience in analyzing Antarctic samples with low fossil recovery finally led to a scientific breakthrough. view more (2009-10-01)
Scientists use meteors to investigate climate change and giant waves at the 'edge of space'
A new research radar based in Antarctica is giving scientists the chance to study the highest layer of the earth's atmosphere at the very edge of space. view more (2005-05-23)
NASA provides new perspectives on the earth's changing ice sheets
It's widely documented that climate change is causing the Greenland and Antarctic ice sheets to shrink. Air temperatures in many parts of the polar regions have increased and waters that surround parts of the ice sheets have warmed up. view more (2006-12-12)
Glaciers and ice caps to dominate sea level rise this century, says CU-Boulder study
Ice loss from glaciers and ice caps is expected to cause more global sea rise during this century than the massive Greenland and Antarctic ice sheets, according to a new University of Colorado at Boulder study. view more (2007-07-20)
Unusual Antarctic microbes live life on a previously unsuspected edge
An unmapped reservoir of briny liquid chemically similar to sea water, but buried under an inland Antarctic glacier, appears to support unusual microbial life in a place where cold, darkness and lack of oxygen would previously have led scientists to believe nothing could survive, according to newly published research. view more (2009-04-17)
ANDRILL's 2nd Antarctic drilling season exceeds all expectations
A second season in Antarctica for the Antarctic Geological Drilling (ANDRILL) Program has exceeded all expectations, according to the co-chief scientists of the program's Southern McMurdo Sound Project. view more (2007-11-28)
