Scientists probe Antarctic glaciers for clues to past and future sea level
Scientists from the U.S., U.K. and Australia have teamed up to explore two of the last uncharted regions of Earth, the Aurora and Wilkes Subglacial Basins, immense ice-buried lowlands in Antarctica with a combined area the size of Mexico. view more (2008-10-28)
Scientists Detect Thinning West Antarctic Ice.
A major glacial formation in Antarctica is shrinking, a report in SCIENCE will reveal today. But questions still remain about the speed at which ice sheet thinning is taking place. Scientists at University College London (UCL) and the British Antarctic Survey have used satellite data to show that the interior of the West Antarctic Ice Sheet (WAIS)... view more... (2001-01-29)
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)
Past climate of the northern Antarctic Peninsular informs global warming debate
The seriousness of current global warming is underlined by a reconstruction of climate at Maxwell Bay in the South Shetland Islands of the Antarctic Peninsula over approximately the last 14,000 years, which appears to show that the current warming and widespread loss of glacial ice are unprecedented. view more (2009-11-09)
Satellites capture first-ever gravity map of tides under Antarctic ice
Ohio State University scientists have used minute fluctuations in gravity to produce the best map yet of ocean tides that flow beneath two large Antarctic ice shelves. view more (2005-12-05)
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)
Climate Research: Oldest Ice in Process
Scientists at the Alfred Wegener Institute for Polar and Marine Research (AWI) are handling the oldest ice that has ever been unearthed: The ice cores, which were drilled during last winter in the Antarctic research station Dome C, are up to 900.000 years old. They come from a depth of 3200 metres and contain information about the climate and... view more... (2003-11-14)
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)
Boston university researchers develop new model of ice volume change based on Earth's orbit
Through dated geological records scientists have known for decades that variations in the Earth's orbit around the sun — subtle changes in the distance between the two — control ice ages. view more (2006-06-23)
Rapid temperature increases above the Antarctic
A new analysis of weather balloon observations from the last 30 years reveals that the Antarctic has the same 'global warming' signature as that seen across the whole Earth, but is three times larger than that observed globally. view more (2006-03-31)
Study Finds Subglacial Water in West Antarctica Considerably More Active Than Previously Observed
The recent discovery of a subglacial water system beneath the West Antarctic ice sheet (WAIS) is causing scientists to rethink the mechanisms that control the flow of ice streams into the Ross Ice Shelf and ultimately into the Southern Ocean, according to a report in the February 15, 2007, issue of Science magazine online. view more (2007-02-16)
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)
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)
Greenland and Antarctic ice sheet melting, rate unknown
The Greenland and Antarctica ice sheets are melting, but the amounts that will melt and the time it will take are still unknown, according to Richard Alley, Evan Pugh professor of geosciences, Penn State. view more (2009-02-17)
Global warming, Antarctic ice is focus of multinational workshop
As the national repository for geological material from the Southern Ocean, the Antarctic Marine Geology Research Facility at Florida State University houses the premier collection of Antarctic sediment cores -- and a hot new acquisition will offer an international team of scientists meeting there May 1-4 its best look yet at the impact of global... view more...

Cosmic dust in terrestrial ice
For the last 30,000 years, our planet has been hit by a constant rain of cosmic dust particles. view more (2006-07-28)
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)
Exploration of lake hidden beneath Antarctica's ice sheet begins
A four-man science team led by British Antarctic Survey's (BAS) Dr Andy Smith has begun exploring an ancient lake hidden deep beneath Antarctica's ice sheet. view more (2008-01-16)
Andrill demonstrates climate warming affects Antarctic ice sheet stability
A five-nation scientific team has published new evidence that even a slight rise in atmospheric concentrations of carbon dioxide, one of the gases that drives global warming, affects the stability of the West Antarctic Ice Sheet (WAIS). view more (2009-03-19)
