Thin tough skin, slow-growing gills protect larval Antarctic fish
Very thin but hardy, unblemished skin and slow developing gills appear to be keys to survival for newly hatched Antarctic notothenioids, a group of fish whose adults thrive in icy waters because of antifreeze proteins (AFPs) in their blood. view more (2006-02-14)
Polar neutrino observatory takes a big step forward
An international team of scientists and engineers has taken a major step toward completion of what will be the world's preeminent cosmic neutrino observatory, harnessing a sophisticated hot-water drill to build an observatory under the South Pole that eventually will encompass a cubic kilometer of ice. view more (2006-03-22)
Satellites witness lowest Arctic ice coverage in history
The area covered by sea ice in the Arctic has shrunk to its lowest level this week since satellite measurements began nearly 30 years ago, opening up the Northwest Passage - a long-sought short cut between Europe and Asia that has been historically impassable. view more (2007-09-17)
Data show Antarctic ice stream radiating seismically
A seismologist at Washington University in St. Louis and colleagues at Pennsylvania State University and Newcastle University in the United Kingdom have found seismic signals from a giant river of ice in Antarctica that makes California's earthquake problem seem trivial. view more (2008-06-05)
LIFE IN A FROZEN ENVIRONMENT-WHATS IN IT FOR US?
Life on the moons of Jupiter, and a source of healthy polyunsaturated fatty acids and low temperature enzymes that could even make washing powders work at low temperatures: The microbes that live in Antarctic sea ice may hold the answers to a host of everyday applications as well as revealing how life forms might be able to exist on frozen... view more...

Computer models show major climate shift as a result of closing ozone hole
A new study led by Columbia University researchers has found that the closing of the ozone hole, which is projected to occur sometime in the second half of the 21st century, may significantly affect climate change in the Southern Hemisphere, and therefore, the global climate. view more (2008-06-13)
New ice cores expand view of climate history
Two new studies of gases trapped in Antarctic ice cores have extended the record of Earth's past climate almost 50 percent further, adding another 210,000 years of definitive data about the makeup of the Earth's atmosphere and providing more evidence of current atmospheric change. view more (2005-11-28)
Alaskan storm cracks giant iceberg to pieces in faraway Antarctica
A severe storm that occurred in the Gulf of Alaska in October 2005 generated an ocean swell that six days later broke apart a giant iceberg floating near the coast of Antarctica, more than 8,300 miles away. view more (2006-10-03)
New Antarctic ice core to provide clearest climate record yet
After enduring months on the coldest, driest, and windiest continent on Earth, researchers today closed out the inaugural season on an unprecedented, multi-year effort to retrieve the most detailed record of greenhouse gases in Earth's atmosphere over the last 100,000 years. view more (2008-01-24)
Geophysical Research Letters European Highlights - 1 August 2001
Highlights 4. Deep water has many sources Hellmer and Beckmann ["The Southern Ocean: A Ventilation Contributor with Multiple Sources"] use a coupled ocean/ice-shelf model to determine the location and rate of Antarctic Bottom Water (AABW) formation. Their results suggest that the Atlantic and Indian-Pacific are equal contributors but produce... view more... (2001-07-16)
Icy calculations on a hot topic
University of Utah mathematicians have arrived at a new understanding of how salt-saturated ocean water flows through sea ice - a discovery that promises to improve forecasts of how global warming will affect polar icepacks. view more (2007-09-11)
Want to monitor climate change? P-p-p-pick up a penguin!
We are used to hearing about the effects of climate change in terms of unusual animal behaviour, such as altering patterns of fish and bird migration. view more (2007-04-04)
Breakup of glaciers raising sea level concern
The rapid structural breakdown of some important parts of the ice sheets on Greenland and Antarctica is possible, has happened in the distant past, and some "startling changes" on the margin of these ice masses has been observed in recent years - raising disturbing concerns about sea level rise. view more (2005-10-21)
NASA researchers find snowmelt in Antarctica creeping inland
On the world's coldest continent of Antarctica, the landscape is so vast and varied that only satellites can fully capture the extent of changes in the snow melting across its valleys, mountains, glaciers and ice shelves. view more (2007-09-21)
Russia Returns To Arctic On A Drifting Ice-floe
After a long break Russia is getting ready to resume the research in Arctic with the help of floating stations. As Valery Martyshenko (Rosgidromet) has advised InformNauka, an appropriate ice-floe is currently being looked for, and the 32nd station will start the floating in the last decade of April. Vladimir Sokolov, Head of the SP-32 floating... view more... (2003-03-25)
High degree of resistance to antibiotics in Arctic birds
In the latest issue of the journal Emerging Infectious Diseases, Swedish researchers report that birds captured in the hyperboreal tundra, in connection with the tundra expedition "Beringia 2005," were carriers of antibiotics-resistant bacteria. view more (2008-01-14)
Ozone hole recovery may reshape southern hemisphere climate change
A full recovery of the stratospheric ozone hole could modify climate change in the Southern Hemisphere and even amplify Antarctic warming, according to scientists from the University of Colorado at Boulder, the National Oceanic and Atmospheric Administration and NASA. view more (2008-04-25)
Geologists: Opening of passage may be tied to Antarctic cooling
Ancient fish teeth are yielding clues about when Antarctica became the icy continent it is today, highlighting how ocean currents affect climate change. view more (2006-04-21)
Arctic ice on the verge of another all-time low
Following last summer's record minimum ice cover in the Arctic, current observations from ESA's Envisat satellite suggest that the extent of polar sea-ice may again shrink to a level very close to that of last year. view more (2008-08-29)
Glaciers adding more to global sea rise than ice sheets, says University of Colorado study
Despite growing public alarm over the shrinking Greenland and Antarctic ice sheets, it is small glaciers and ice caps that have been contributing the most to rising sea levels in recent years, according to a new University of Colorado at Boulder study. view more (2006-12-12)
