Antarctic ice sheet losing mass, says University of Colorado study
University of Colorado at Boulder researchers have used data from a pair of NASA satellites orbiting Earth in tandem to determine that the Antarctic ice sheet, which harbors 90 percent of Earth's ice, has lost significant mass in recent years. view more (2006-03-03)
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)
Parachuting allows krill to eat and run
Antarctic researchers have recorded a novel behavior in krill that may help regulate greenhouse gases. Antarctic krill, one of the largest animal resources on Earth, parachute into the deeper layers of the ocean many times a night and sequester large amounts carbon in the process. view more (2006-02-07)
Alaska's Columbia Glacier continues on disintegration course
Alaska's rapidly disintegrating Columbia Glacier, which has shrunk in length by 9 miles since 1980, has reached the mid-point of its projected retreat, according to a new University of Colorado at Boulder study. view more (2005-12-08)
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)
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)
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)

The Antarctic Peninsula is undergoing greater warming than almost anywhere on Earth, a condition perhaps associated with human-induced greenhouse effects. view more (2005-08-04)
Space shuttle Columbia's last flight formed clouds over Antarctica
A burst of mesospheric cloud activity over Antarctica in January 2003 was caused by the exhaust plume of the space shuttle Columbia during its final flight, reports a team of scientists who studied satellite and ground-based data from three different experiments. view more (2005-07-07)
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)
Antarctica - an awakening giant?
The crucial role that Antarctica plays in global climate change and its future contribution to sea-level rise was highlighted today by Professor Chris Rapley, Director of British Antarctic Survey (BAS). Speaking at an international convention on climate change in Bonn, Germany* he presented a summary of the latest scientific results from... view more... (2005-05-19)
In the Cornucopia of the European Project of Ice Coring in Antarctica: the oldest Antarctic ice core
On Tuesday 21th of December 2004 a European team involved in Epica (European Project for Ice Coring in Antarctica) reached the drilling depth of 3270.2, which is five meters above the bedrock at Dome C, on the central plateau of the east Antarctic ice sheet. The ice is melting at the bedrock and it has been decided to stop at this depth to avoid... view more... (2005-01-13)
Geologist Warms Up For Antarctic Expedition
It won't quite be a white Christmas for Professor Nick Petford, but the Kingston University geologist will see in the New Year in sub-zero temperatures. Professor Petford, from the Centre for Earth and Environmental Science Research, flies out to Antarctica on December 27 to investigate the ancient interiors of volcanoes. He has been selected as... view more... (2004-12-15)
Food shortages threaten Antarctic wildlife
Antarctic whales, seals and penguins could be threatened by food shortages in the Southern Ocean. Numbers of Antarctic krill (Euphausia superba), a shrimp-like crustacean at the heart of the food chain, are declining. The most likely explanation is a dramatic decline in sea-ice. The results are published this week in the journal Nature. view more (2004-11-01)

Endangered polar heritage
There are 76 sites on the official list of historic sites and monuments in Antarctica. 11 of them are, or used to be, Norwegian. Cultural heritage is a non-renewable resource endangered by environmental pollutants and increased tourism. -We need a lot more research on Norwegian historic sites in Antarctica, says Susan Barr, special adviser at the... view more...
