Sentences with phrase «glacial flow»

The phrase "glacial flow" refers to the slow movement of ice in a glacier, similar to the way a river flows, but much colder. Full definition
This map shows the pace of glacial flow between 1996 and 2008.
Here we have some healthy evidence not just for the dynamics of glacial flow, but also for the feedback loops within the scientific community.
Ice shelves maintain the stability of the ice on the continent: a huge ice shelf slows glacial flow from the highlands and effectively constrains the flow of meltwater.
Current climate models do not take into account glacial flow and therefore underestimate the impact of glacial melt and the calving of ice flows, the researchers argue in a paper detailing the findings in today's Science.
Since so much of the ice sheet is grounded underwater, rising sea levels may have the effect of lifting the sheets, allowing more - and increasingly warmer - water underneath it, leading to further bottom melting, more ice shelf disintegration, accelerated glacial flow, and further sea level rise, and so on and on, another vicious cycle.
According to the new analysis, the amount of ice loss due to glacier glacial flow rose from 50 cubic kilometres per year in 1996 to 150 km3 in 2005.
Since Larsen B's collapse, ice - sheet modellers have tweaked their simulations to better reflect the forces driving glacial flow and to help quantify this corking effect — bolstering confidence that limited observations from the Larsen ice shelves could be applied more broadly.
According to climate records stretching back a century, southern Greenland has warmed three degrees Celsius in just the past 20 years, driving melting that may help lubricate glacial flow along the bedrock, the two speculate.
The volatile methane, carbon monoxide, and nitrogen ices that dominate Pluto's surface have complicated spatial distributions resulting from sublimation, condensation, and glacial flow acting over seasonal and geological time scales.
Richard, S.M., and Luyendyk, B.P., Glacial flow reorientation in the southwest Fosdick Mountains, Ford Ranges, Marie Byrd Land.
But in the last 20 years, observers have measured the successive losses to large areas of the Larsen ice shelf off the Antarctic Peninsula, and these have resulted in an alarming acceleration of glacial flow on land, even though Antarctica remains the coldest continent on Earth.
Could the Times consider finding and covering any speculations from reasonably reliable sources on what happens to us and our societies should moulin production increase triggering increased glacial flows and a resultant sea rise of, shall we say, two meters in a century?
When floating ice shelves disintegrate, they reduce the resistance to glacial flow and thus allow the grounded glaciers they were buttressing to significantly dump more ice into the ocean, raising sea levels.
In a series of papers, the New Horizons team present their analysis of the encounter data downloaded so far: Moore et al. present the complex surface features and geology of Pluto and its large moon Charon, including evidence of tectonics, glacial flow, and possible cryovolcanoes.
«Greenland is probably going to contribute more and faster to sea level rise than predicted by current models,» said Eric Rignot, a glaciologist at NASA's Jet Propulsion Laboratory who studied the glacial flow in a paper in Science last year.
The lake is a surreal turquoise color due to the glacial flow coming down from the surrounding mountains.
This accelerates the glacial flow and the calving of icebergs into the surrounding ocean.
Looking at these glacial flows individual contributions to overall mean sea level rise (MSLR) and talking in terms of decades to centuries for their collapse makes the problem seem very far off in human terms.
Goodman, JC and Pierrehumbert RT 2003: Glacial flow of floating marine ice in Snowball Earth.
The supposed mass loss (which is questionable, as Dave Wendt argues) is due instead to increased glacial flow, which in turn is due to a prior mass buildup from precipitation, which caused increased pressure.
The air temperature there has been steady in recent decades, and the water temperature, which has been suspected of warming and allowing the jammed ice shelves along the shore to loosen, permitting increased glacial flow, doesn't seem to be doing so:
Climate News Network: Researchers in the US have identified a new reason for the acceleration in the melting of Greenland's icecap − the ice underneath, as it melts and then refreezes, appears to speed up glacial flow.
A NASA project has for the first time mapped the glacial flows of Antarctica, providing vital information in the monitoring of climate change.
The data might be sensitive to changes of ice cover in the seas near Greenland, or to a local shift of the ice cap's glacial flow.
Or what if stronger tides increased glacial flow or calving at the coasts, or tidal currents openned up gaps in sea ice covering by piling sea ice against islands, thus affecting albedo and surface heat fluxes?
To know when, we have to calculate using another simulation (model) and take into account the glacial flow,» Fujita said, but added that his team did not have the data to do so at the moment.
The researchers do not yet know whether the draining water is increasing glacial flow, and nor can they be sure how many such depressions in the Greenland ice mask buried meltwater storage tanks.
These include the fine detail of atmospheric warming and ice dynamics — what rainwater might do to the ice sheet that floats on the Southern Ocean and blocks the glacial flow from the land, for instance, and what makes ice cliffs collapse into the sea — along with a lot of lessons from the past.
