Antarctic snow inaccurate temperature archive
According to Dutch researcher Michiel Helsen, annual and seasonal temperature fluctuations are not accurately recorded in the composition of the snow of Antarctica. His research into the isotopic composition of the Antarctic snow has exposed the complexity of climate reconstructions. view more (2006-02-16)
Researchers plumb mysteries of Antarctic Mountains
The 3,000-kilometer-long Transantarctic Mountains are a dominant feature of the Antarctic continent, yet up to now scientists have been unable to adequately explain how they formed. view more (2007-07-20)

International meeting on the Southern Ocean
The Role of the Southern Ocean in Global Processes: an Earth System Science Approach - 14-16 July 2003, London Over 80 experts from around the world will meet next week (14-16 July) to discuss the Southern Ocean surrounding Antarctica. It's the first attempt by scientists to take a collective approach to investigating an important marine... view more... (2003-07-10)
Giant project to test Antarctic ice stability
If rising global temperatures cause the ice streams of Western Antarctica to break up, major cities and agricultural heartlands the world over would be submerged. Researchers from the University of Leeds' School of Geography are set to embark on a £1m, three-year project to find out exactly how stable they are. view more (2004-05-10)
Antarctic Ice Core milestone - 2002 m reached as year 2002 arrives
In the first weeks of the New Year a team of European scientists drilled successfully through 2002 metres of ice at Dome Concordia, high on East Antarctica`s plateau - one of the most hostile places on the planet. A specially created laboratory on the ice enabled scientists to analyse, for the first time, past climate shifts within hours of each 3... view more... (2002-01-15)
Has the mystery of the Antarctic ice sheet been solved?
A team of scientists from Cardiff University's School of Earth and Ocean Sciences and Amgueddfa Cymru - National Museum Wales travelled to Africa to find new evidence of climate change which helps explain some of the mystery surrounding the appearance of the Antarctic ice sheet. view more (2008-02-28)
As ozone hole approaches annual peak, NASA scientists reveal latest information and images
In 1987, the United States joined several other nations in signing the Montreal Protocol, an international treaty designed to protect the Earth's ozone layer by phasing out the production of a number of substances believed to be responsible for ozone depletion. view more (2006-09-29)
Cold colony vulnerable to environmental challenge
Australia and other owners of the Antarctic territories may be ill-prepared to face a major environmental challenge to the continent, according to a Queensland University of Technology academic. view more (2007-10-19)
Unexpected growth in atmospheric CO2
A team of scientists has found that atmospheric carbon dioxide (CO2) growth has increased 35 percent faster than expected since 2000. The findings are published this week in the journal Proceedings of the National Academy of Sciences (PNAS). view more (2007-10-23)
Robot submarine reveals secret stash of key Antarctic food source under sea ice
A robot submarine expedition under the Antarctic sea ice has discovered a major food reserve in the Southern Ocean. The findings, reported this week in SCIENCE, show a dense band of the shrimp-like krill under the ice, five times more concentrated than in open water. The importance of sea ice as a nursery for krill - key food for penguins, whales... view more... (2002-03-05)
Arctic, antarctic melting may raise sea levels faster than expected
Ice sheets across both the Arctic and Antarctic could melt more quickly than expected this century, according to two studies that blend computer modeling with paleoclimate records. view more (2006-03-24)
Astronomers find coldest, driest, calmest place on Earth
The search for the best observatory site in the world has lead to the discovery of what is thought to be the coldest, driest, calmest place on Earth. view more (2009-08-31)
Geological reasons of ozone layer destruction
The modern science admits that the ozone concentration in the stratosphere is diminishing. This process has been fixing since the middle of 1980s. "The most popular hypothesis about technogenic freon that destroys the ozone layer is quite vulnerable", - said Dr. of geology Vladimir Sivorotkin who studies the problem of the ozone layer for ten... view more...

Seafloor creatures destroyed by ice action during ice ages
The ice ages made massive changes to the Earth's landscape. But what was happening below the ice in the oceans? view more (2005-10-18)
Snowball Antarctica - early Drake passage opening led to global change
New results shed light on how Antarctica became the icy, barren continent that we know today. view more (2005-08-31)
Study shows snowfall hasn't increased over Antarctica in last 50 years
An international effort to determine the variability of recent snowfall over Antarctica shows that there has been no real increase in precipitation over the southernmost continent in the last half-century. view more (2006-08-11)
Giants joust in the cold
A new giant was born recently in the coastal waters of Antarctica. A series of images captured from May through the beginning of this month by ESA`s Envisat satellite shows the subsequent duel between the new iceberg and another as it breaks free of the Ross Ice Shelf and tries to move north. Christened C-19 by the US National Ice Centre in... view more... (2002-10-22)
Warmer air may cause increased Antarctic sea ice cover
Predicted increases in precipitation due to warmer air temperatures from greenhouse gas emissions may actually increase sea ice volume in the Antarctic's Southern Ocean. view more (2005-06-30)
Study of underground lakes in Antarctica could be critical, prof says
The discovery of interconnected lakes beneath kilometers of ice in Antarctica could be one of the most important scientific finds in recent years, but proper procedures need to be established before investigation begins, says a Texas A&M University scientist who is a leader in the research efforts. view more (2007-06-06)
