British scientists say they have created a model of the British and Irish ice sheets that shows they moved in unexpected ways. Durham University researchers said their model reveals for the first time how the glaciers reversed their flows and retreated back into upland regions from where they originated. During the last glacial maximum, around 21,500 years ago, the ice sheets built up on the high land of the Lake District, north Pennines and Scottish Southern Uplands, the researchers said. As...

Dust trapped deep in Antarctic ice sheets is helping scientists unravel details of past climate change. Researchers have found that dust blown south to Antarctica from the windy plains of Patagonia "“ and deposited in the ice periodically over 80,000 years "“ provides vital information about glacier activity. Scientists hope the findings will help them to better understand how the global climate has changed during the past ice age, and so help predict environmental changes in the...

Researchers Make First Observations of Surface Meltwater Cutting through the Ice Sheet to Lubricate the BottomResearchers from the Woods Hole Oceanographic Institution (WHOI) and the University of Washington (UW) have for the first time documented the sudden and complete drainage of a lake of meltwater from the top of the Greenland ice sheet to its base.From those observations, scientists have uncovered a plumbing system for the ice sheet, where meltwater can penetrate thick, cold ice and...

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. In a new study, researchers have unearthed how water from this vast subglacial system contributes to the formation of ice streams, and how it plays a crucial role in transporting ice from the remote interior of Antarctica toward the...

Fairbanks, Alaska - Continued arctic warming may be causing a decrease in the number and size of Arctic lakes. The issue is the subject of a paper published in the June 3 issue of the journal "Science." The paper, titled, "Disappearing Arctic Lakes" is the result of a comparison of satellite data taken of Siberia in the early 1970s to data from 1997-2004. Researchers, including Larry Hinzman with the Water and Environmental Research Center at the University of Alaska Fairbanks, tracked...

Meltwater is water that is released from melting snow or ice. This includes meltwater from glacial ice and ice shelves over oceans. Meltwater is often produced during volcanic eruptions, and can cause dangerous lahars (landslides of wet volcanic debris). When meltwater pools on the surface rather than draining or flowing away, it forms pools known as melt ponds. Meltwater will often refreeze as the temperature drops. Meltwater can also collect or melt under the ice's surface. Sub-glacial...
