Volcanic blast likely killed and preserved juvenile fossil plesiosaur found in Antarctica
Amid 70-mile-an-hour winds and freezing Antarctic conditions, an American-Argentine research team has recovered the well-preserved fossil skeleton of a juvenile plesiosaur-a marine reptile that swam the waters of the Southern Ocean roughly 70 million years ago.   view more (2006-12-12)

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...

Brown University Geologists Create 5-Million-Year Climate Record
Using chemical clues mined from ocean mud, Brown University researchers have generated the longest continuous record of ocean temperatures on Earth.   view more (2006-04-07)

Laser technique has implications for detecting microbial life forms in Martian ice
An innovative technique called L.I.F.E. imaging used successfully to detect bacteria in frozen Antarctic lakes could have exciting implications for demonstrating signs of life in the polar regions of Mars.   view more (2009-10-02)

New simulation shows consequences of a world without Earth's natural sunscreen
Nearly two-thirds of Earth's ozone is gone -- not just over the poles, but everywhere. The infamous ozone hole over Antarctica, first discovered in the 1980s, is a year-round fixture, with a twin over the North Pole. The ultraviolet (UV) radiation falling on mid-latitude cities like Washington, D.C., is strong enough to cause sunburn in just five... view more... (2009-03-19)

Burning asteroids may play 'more important climate role than previously recognized'
Dust from asteroids entering the atmosphere may influence Earth's weather more than previously believed, researchers have found.   view more (2005-08-26)

Antarctic Ice Sheet's Hidden Lakes Speed Ice Flow Into Ocean, May Disrupt Climate
Just as explorers once searched the vast reaches of Africa's Nile River for clues to its behavior and ultimate source, modern-day scientists are searching Antarctica for its hidden lakes and waterways that can barely be detected at the surface of the ice sheet.   view more (2007-03-07)

Hundreds of Antarctic Peninsula glaciers accelerating as climate warms
Hundreds of glaciers on the Antarctic Peninsula are flowing faster, further adding to sea level rise according to new research published this week in the Journal of Geophysical Research. Climate warming, that is already causing Antarctic Peninsula increased summer snow melt and ice shelf retreat, is the most likely cause.    view more (2007-06-06)

Antarctic ice shelf disintegrating as result of climate change, say scientists
Satellite imagery from the University of Colorado at Boulder's National Snow and Ice Data Center shows a portion of Antarctica's massive Wilkins Ice Shelf has begun to collapse because of rapid climate change in a fast-warming region of the continent.   view more (2008-03-26)

Antarctic marine biodiversity data now online
The International Polar Year (IPY) concluded in March 2009 with a tangible legacy in the form of a network of databases on marine biodiversity that will serve as clearinghouse for all biodiversity-related data gathered since the very first Antarctic research expeditions.   view more (2009-03-31)

Earth's heat adds to climate change to melt Greenland ice
Scientists have discovered what they think may be another reason why Greenland's ice is melting: a thin spot in Earth's crust is enabling underground magma to heat the ice. They have found at least one "hotspot" in the northeast corner of Greenland -- just below a site where an ice stream was recently discovered.   view more (2007-12-13)

Radar opens new window into the ice for Antarctic scientists
Scientists are getting their first glimpse into the inner secrets of an ice shelf, thanks to the innovative application of a new radar technique developed by British Antarctic Survey (BAS).   view more (2006-10-17)

European lead in reading past climates from ice cores
Climate change is a reality today, but how can we find out about the future dangers it poses" What we really need is a full record of the Earth's climate for several hundred thousand years, complete with samples of air from different epochs that can be taken to the lab for analysis.   view more (2007-10-12)

Scientific breakthrough will help protect astronauts and spacecraft
A breakthrough by a team of British, US and French scientists will help protect astronauts, spacecraft and satellites from radiation hazards experienced in space.   view more (2005-09-08)

International team establishes unique observatory in Antarctica
A team of scientists representing six international institutions, including Texas A&M University, has succeeded in reaching the summit of Antarctica - also a monumental achievement for ground-based astronomy -- to establish a new astronomical observatory at Dome Argus on the highest point of the Antarctic Plateau.   view more (2008-02-04)

IGBP calls for better observation of Earth's "Achilles' heels"
Monitoring the most sensitive "hotspots" of the Earth is an important way of assessing the health of our planet and predicting our future, said IGBP (International Geosphere-Biosphere Programme) scientists speaking at the Earth Observation Summit in Washington last week. The summit was attended by officials from more than 30 countries... view more... (2003-08-06)

Oldest Antarctic ice core reveals climate history
Secrets of the Earth's past climate locked in a three-kilometre long Antarctic ice core are revealed this week in the journal Nature. The core from Dome C, high on East Antarctica's plateau, contains snowfall from the last 740,000 years and is by far the oldest continuous climate record obtained from ice cores so far. The ice has been collected... view more... (2004-06-03)

Study Offers Preview of Ice Sheet Melting, Rapid Climate Changes
The retreat of a massive ice sheet that once covered much of northern Europe has been described for the first time, and researchers believe it may provide a sneak preview of how present-day ice sheets in Greenland and Antarctica will act in the face of global warming.   view more (2006-03-15)
