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)
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)
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)
Research finds that Earth's climate is approaching 'dangerous' point
NASA and Columbia University Earth Institute research finds that human-made greenhouse gases have brought the Earth's climate close to critical tipping points, with potentially dangerous consequences for the planet. view more (2007-06-01)
NASA Study Finds Clock Ticking Slower On Ozone Hole Recovery
The Antarctic ozone hole's recovery is running late. According to a new NASA study, the full return of the protective ozone over the South Pole will take nearly 20 years longer than scientists previously expected. view more (2006-06-30)
Arctic sea ice minimum shatters all-time record low, report University of Colorado scientists
Scientists from the University of Colorado at Boulder's National Snow and Ice Data Center said today that the extent of Arctic sea ice appears to have reached its minimum for 2007 on Sept. 16, shattering all previous lows since satellite record-keeping began nearly 30 years ago. view more (2007-09-21)
Antarctic plants repair themselves
Dutch researchers funded by NWO have studied the effects of the hole in the ozone layer on the vegetation in Antarctica. The repair mechanisms of lichens and mosses appear to be effective even at low temperatures. Nevertheless, the ecology of the Antarctic is still under threat. The rise in temperature caused by the greenhouse effect is doing... view more... (2001-11-26)
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)
Mathematics and climate change
In 1994, University of Utah mathematician Ken Golden went to the Eastern Weddell Sea for the Antarctic Zone Flux Experiment. The sea's surface is normally covered with sea ice, the complex composite material that results when sea water is frozen. view more (2009-04-13)
By ice floe to the North Pole
At the end of August, an unusual expedition under Russian leadership will leave for the Arctic Ocean. One of the participants is Jürgen Graeser of the Alfred Wegener Institute for Polar and Marine Research, one of the research centres of the Helmholtz Association. view more (2007-07-23)
Global warming could lead to a greener Greenland (embargoed until 18.00 BST)
Research published in Nature suggests that enough greenhouse gases could be in the atmosphere as early as 2050 to melt the massive ice-sheet that covers Greenland. As a result, sea levels could rise by around seven metres over the next 1,000 years. Along with colleagues in Belgium and Germany, Dr Jonathan Gregory, of the Centre for Global... view more...

NASA Scientist Claims Warmer Ocean Waters Reducing Ice Worldwide
According to a NASA scientist, the pieces to a years-old scientific puzzle have come together to confirm warmer water temperatures are creeping into the Earth's colder areas. Those warm waters are increasing melting and accelerating ice flow in polar areas. view more (2006-03-24)
Sea Birds May Soon Need Rehabilitation
Oil spills are a real disaster. They cause worst troubles to sea birds and animals. A risk of an accident always exists within areas of oil mining and transporting, especially, in the sea. Beginning the exploitation of oil and gas fields on the sea shelf, our country is to face inevitable ecological problems, and it would be helpful to know in... view more... (2004-02-06)
Antarctic expedition provides new insights into the role of the Southern Ocean for global climate
In the Southern Ocean, large quantities of surface-drifting plankton algae are able to significantly reduce the carbon dioxide content of the surface waters, which can affect the global carbon dioxide cycle. view more (2008-02-06)
Researchers say Arctic sea ice still at risk despite cold winter
Using the latest satellite observations, NASA researchers and others report that the Arctic is still on "thin ice" when it comes to the condition of sea ice cover in the region. A colder-than-average winter in some regions of the Arctic this year has yielded an increase in the area of new sea ice, while the older sea ice that lasts for... view more... (2008-03-19)
Mars With Ice, Shaken, Not Stirred
Mars, like Earth, is a climate-fickle water planet. The main difference, of course, is that water on the frigid Red Planet is rarely liquid, preferring to spend almost all of its time traveling the world as a gas or churning up the surface as ice. view more (2007-10-26)
Global warming may not have ended Ice-Age, says research
Scientists at the University of Sheffield have used fossilised leaves to determine the effect of greenhouse gases on the end of the Ice Age 300m years ago, according to an article published in PNAS. The study, led by Professor David Beerling, examined fossilised leaves to determine how much carbon dioxide was in the air at various periods during... view more... (2002-09-12)
U.S.-Led, International AGAP Team Poised to Probe One of Antarctica's Last Unexplored Places
A U.S.-led, multinational team of scientists from six nations will pierce the mysteries of one of the globe's last major unexplored places this month. Using sophisticated airborne radar and other Information Age tools and techniques, the scientists will virtually "peel away" more than four kilometers (2.5 miles) of ice covering an... view more...

Strengthening case for life on Mars - CMD19CMMP with The Physics Congress 2002
When it was announced last month that the Mars Odyssey satellite had found water ice beneath the planet`s frozen carbon dioxide south polar ice cap, "I felt excited!" says Dr Lidija Siller, a physicist from the University of Newcastle. "I believe that the data I have explains how this water became trapped underneath the surface". Dr Siller will be... view more... (2002-03-26)
Ice core studies confirm accuracy of climate models
An analysis has been completed of the global carbon cycle and climate for a 70,000 year period in the most recent Ice Age, showing a remarkable correlation between carbon dioxide levels and surprisingly abrupt changes in climate. view more (2008-09-12)
