Scientists from several nations are working together to launch a flagship program to explore a major mountain range buried by a large continental ice sheet and bounded by numerous subglacial lakes.
Antarctic sea ice seasonal forecasts based on a linear Markov model are in high demand for both observational and climate communities. They are provided by Xiaojun Yuan and Dake Chen.
The ring of deep water around Antarctica not only links the major ocean [Atlantic/Pacific/Indian] , but also produces dense waters along the continental margins of the frozen continent, which sinks
Citizen scientists can gather data to help uncover how snow is changing over time.
The coasts of Antarctica are ringed with ice shelves – large expanses of ice that float on the surrounding ocean and form the outermost extensions of the glaciers that cover the land behind them. A new study shows that even minor deterioration of ice shelves can instantaneously hasten the motion and loss of ice hundreds of miles landward.
Climate change has become fertile ground for both scientists and artists, with its potential to reshape landscapes as well as human civilization itself.
Two women investigating climate change from different perspectives—Christine McCarthy, a geophysicist at Lamont-Doherty Earth Observatory, and Denise Iris, a multimedia artist from Brooklyn—had a chance to spend several days together recently. In the Rock Mechanics Lab at Lamont, where McCarthy works, and a nearby “cold room” chilled to the climate of an industrial freezer, they exchanged notes on two ways of looking at ice.
New Dating Technique Points to Differences Over 7,000 Years
The vast majority of the world’s glaciers are retreating as the planet gets warmer. But a few, including ones south of the equator, in South America and New Zealand, are inching forward. A new study in the journal Science puts this enigma in perspective.
Under Miles of Ice, Range May Hold Secrets of Geology and Climate
Scientists from six nations will combine efforts over the next three months to try and penetrate one of earth’s last unexplored places: Antarctica’s vast Gamburtsev Mountains, never seen by humans...
North American Ice Sheet Dwindled Fast in Conditions Like Today's
In the face of warming climate, researchers have yet to agree on how much and how quickly melting of the Greenland ice sheet may contribute to sea level rise.
Each year nearly 40,000 tons of cosmic dust fall to Earth from outer space. Now, the first successful chronological study of extraterrestrial dust in Antarctic ice has shown that this amount has remained largely constant over the past 30,000 years, a finding that could help refine efforts to understand the timing and effects of changes in the Earth's past climate.
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.
Lying beneath more than two miles of Antarctic ice, Lake Vostok may be the best-known and largest subglacial lake in the world, but it is not alone down there. Scientists have identified more than 145 other lakes trapped under the ice. Until now, however, none have approached Vostok’s size or depth.
