Studying surging glaciers could also offer insights into grander - scale ice flows with global consequences: the movements of the ice sheets in Antarctica and Greenland, which can change abruptly, altering the ice discharges that affect sea level.

A study published in 2011 by Scambos, Truffer and Pettit found that one glacier continues to accelerate even 15 years after losing its ice shelf: Röhss Glacier (which used to flow into the Prince Gustav ice shelf) has now reached nine times its former speed.

His specialty is studying what happens when flowing lava meets ice and snow.

«This new, huge data volume records how the ice sheet evolved and how it's flowing today,» said Joe MacGregor, the study's lead author, a glaciologist at The University of Texas at Austin Institute for Geophysics (UTIG), a unit of the Jackson School of Geosciences.

Rising temperatures since the 1950s probably quickened the ice flow, which in turn put more strain on the ice and further weakened the shelf, says study coauthor Hongxing Liu, a geographer at the University of Cincinnati.

One 2004 NASA - led study found that most of the glaciers they were studying «flow into floating ice shelves over bedrock up to hundreds of meters deeper than previous estimates, providing exit routes for ice from further inland if ice - sheet collapse is under way.»

«Ice will flow faster over sediments, like those found in rifts,» said Bell, a veteran Antarctic researcher, who has long studied yet another dramatic, yet invisible geological feature, the hidden Gamburtsev Mountains in East Antarctica.

«Arctic current flowed under deep freeze of last ice age, study says.»

Hello, I am a graduate student from China, studying Antarctica ice flow, ice sheet dynamics and mass balance.

A study published in February also documented changes in the glacier's flow rate, indicating that little - studied ice shelves are starting to get more attention as scientists» understanding of ice and satellite coverage improves.

According to NASA Goddard Institute of Space Studies, Kansas will be 4 degrees warmer in winter without Arctic ice, which regularly generates cold air masses that flow southward into the U.S. (You've probably heard weather forecasters say the following hundreds of times: People in the middle part of the country had better button up.

«Most ice cores are collected from the middle of the ice sheet where it rarely ever melts, or on the ice sheet edge where the meltwater flows into the ocean,» Karina Graeter, the lead author of the study as a graduate student in Dartmouth's Department of Earth Sciences, said in a statement.

The MISI is based on a number of studies that indicated the theoretical existence of the instability... The most fundamental derivation, that is, starting from a first - principle ice equation, states that in one - dimensional ice flow the grounding line between grounded ice sheet and floating ice shelf can not be stable on a landward sloping bed.

The highs tend to enhance the flow of warm, moist air over Greenland, contributing to increased extreme heat events and surface ice melting, according to the study.

He gained widest fame for his warning, derived from studies of past climate fluctuations, that great flows of fresh water from melting ice sheets could disrupt Atlantic Ocean currents and cause regional cooling (such an idea was caricatured in the Hollywood disaster film «The Day After Tomorrow «-RRB-.

The mechanism for their rapid movement is being intensively studied because of the possibility that rapid ice - stream flow may cause the ice sheet to disintegrate, resulting in a disastrous rise in world - wide sea level.

Half of the ice flows in the Karakoram range of mountains are advancing and not retreating, researchers announced in the first major study since a 2007 United Nations report warned the glaciers would melt by 2035, according to the Daily Mail.

A whole new study points out that the flow has weakened partly due to the warming of the sea and partly due to the meltdown from Greenland's ice cap.

She suggests that future shelf stability studies should consider the role of the ocean's influence, like the effects of warm water pulses flowing under the Cosgrove Ice Shelf.

And study authors found that 2 C to 5 C warming of local ocean waters with somewhat greater local air temperature increases was capable of flooding these basins in stages — forcing Totten's glacial ice to flow out into the Southern Ocean and provide significant contributions to sea level rise.

The study authors conclude that warming temperatures due to climate change are making it more difficult for ice arches to form every winter, preventing them from blocking the southward flow of sea ice.

«The ice shelves buttress the flow from grounded ice into the ocean, and that flow impacts sea - level rise,» Fricker said, «so that's a key concern from our new study.»

Now, a new study finds that these subglacial volcanoes and other geothermal «hotspots» are contributing to the melting of Thwaites Glacier, a major river of ice that flows into Antarctica's Pine [continue reading...]

Tiger Stripes Beneath Antarctic Ice A new study published in Science points out that stripes of dirt and rock beneath Antarctic glaciers create friction zones that slow the flow of ice toward the sIce A new study published in Science points out that stripes of dirt and rock beneath Antarctic glaciers create friction zones that slow the flow of ice toward the sice toward the sea.

So the University of California study delivered a closer look and made a more precise measurement of the flow from the ice cap to the sea.

Thermally incised meltwater channels that flow each summer across melt - prone surfaces of the Greenland ice sheet have received little direct study.

The study argues that ice sheets in contact with the ocean, including the many West Antarctic glaciers that end in floating ice shelves, «are vulnerable to non-linear disintegration» due to a combination of atmospheric warming and major shifts in ocean circulation that would result from a surge in freshwater flowing into the ocean in the North Atlantic (from Greenland), and Southern Ocean (from Antarctica).

Christian Schoof, from the University of British Columbia and the study's author, explains that steady flows of meltwater can be accommodated by existing channels under the Ice Sheet, but rapid flows can not:

However, the the study also found that measurements at the ice's edge show that climate models alone can overestimate the volume of meltwater flowing to the ocean because they fail to account for water storage beneath the ice.
