A new study published this week takes scientists a step further in their quest to understand how Antarctica's vast glaciers will contribute to future sea-level rise. Reporting in the journal Nature Geoscience, scientists from British Antarctic Survey (BAS) and University of Durham describe how a new 3-d map created from radar measurements reveals features in the landscape beneath a vast river of ice, ten times wider than the Rhine*, in the West Antarctic Ice Sheet. During 2007, two...

British scientists plan to use a yellow submarine to explore beneath a giant melting Antarctic glacier whose collapse could raise sea levels 4 inches. The scientists hope to find out why Pine Island Glacier, flowing west-northwest along the south side of the Hudson Mountains into Pine Island Bay, Amundsen Sea, is melting so quickly at its base, said the British Antarctic Survey, Britain's national Antarctic operator. The 23-foot-long, robotic yellow submarine, nicknamed Autosub, will map out...

U.S. scientists say they've created a computer program to help predict when icebergs will calve from ice sheets. The models we have do not currently have any way to figure out where the big ice sheets end and where the ice calves off to form icebergs, said Penn State Professor Richard Alley. The problem, he said, is the great variability involved in iceberg calving. One important variable -- the one that accounts for the largest portion of when the iceberg breaks -- is the rate at which ice...

Scientists have developed computer models that are useful in predicting how fast icebergs break off Antarctica and Greenland. Researchers hope the discovery will enable them to predict rising sea levels due to global warming caused by the burning of fossil fuels. "To predict the future of the ice sheet and to understand the past, we have to put the information into a computer," says Richard B. Alley, the Evan Pugh professor of geosciences at Pennsylvania State University. "The models we have...

Stick, slip, like an earthquakeA seismologist at Washington University in St. Louis and colleagues at Pennsylvania State University and Newcastle University in the United Kingdom have found seismic signals from a giant river of ice in Antarctica that makes California's earthquake problem seem trivial.Douglas A. Wiens, Ph.D., Washington University professor of earth and planetary sciences in Arts & Sciences, and colleagues combined seismological and global positioning system (GPS) analyses...

SAN FRANCISCO -- Two of Greenland's largest glaciers are retreating at an alarming pace, most likely because of climate warming, scientists said Wednesday. One of the glaciers, Kangerdlugssuaq, is currently moving about 9 miles a year compared to 3 miles a year in 2001, said Gordon Hamilton of the University of Maine's Climate Change Institute. The other glacier, Helheim, is retreating at about 7 miles a year - up from 4 miles a year during the same period. "It's quite a staggering...

A multifaceted research effort by scientists at Scripps Institution of Oceanography at the University of California, San Diego, and their international colleagues from the University of Tasmania and the Australian Antarctic Division, has resulted in several important new findings about Antarctica and the changing dynamics of its ice structure. Scientists have been investigating the mechanisms by which Antarctic icebergs detach from the main continental ice sheet because of the importance of...

NASA -- At 32 degrees Fahrenheit, or 0 Celsius, ice changes to water. This simple, unique fact dominates the climate in Earth's polar regions. Using satellites to detect changes over time, NASA researchers and NASA-funded university scientists have found that Earth's ice cover is changing rapidly near its poles. Recent studies point to new evidence of relationships between climate warming, ice changes and sea level rise. Two researchers from NASA Goddard Space Flight Center (GSFC),...

NASA -- When people talk about something moving at a glacial pace, they are referring to speeds that make a tortoise look like a hare. While it is all relative, glaciers actually flow at speeds that require time lapses to recognize. Still, researchers who study Earth's ice and the flow of glaciers have been surprised to find the world's fastest glacier in Greenland doubled its speed between 1997 and 2003. The finding is important for many reasons. For starters, as more ice moves from...
