Sentences with phrase «of ice flow»

As the rivers of ice flow into the ocean, they could cause global sea levels to rise higher and faster than scientists had previously predicted.

The way in which water flows beneath the ice sheet strongly influences the speed of ice flow, so the existence of other lakes will have implications for the future of the ice sheet.

Even with the best numerical model of ice flow available, if the data going into it is not accurate, then the predictions will not be reliable.

Which would mean that the results of this study are consistent with what we are observing in terms of ice flow along the coastline.

Ice stream - A stream of ice flowing faster than the surrounding ice sheet.

• NASA satellites confirm that the rate of ice flow into the ocean from Greenland's Jakobshavn Isbrae glacier — the continent's fastest moving — has doubled between 1997 and 2003, increasing the rate of sea level rise by 4 percent.

As the glacier moves we can track changes between images to produce maps of the ice flow velocity,» says Joughin.

Some scientists assessing the recent acceleration of ice flows propose that the rates of increase can't be sustained long enough to get a truly disastrous rise in seas by 2100 from a warming Greenland.

The models vary in a number of different ways, for example: the way in which they break up the world into discrete elements to solve the equations; the representation of the physics of ice flow; the language the code is written in; whether they are solved on one or many computer processors.

Interaction with the ocean occurs at the undersides of the floating ice shelves and glacier tongues, and consequent changes in thickness affect the rate of ice flow from the grounded ice.

Behold the Mesmerizing Flow of Antarctic Ice The first complete map of the speed and direction of ice flow in Antarctica slid off Science's presses last month and hit the media with a splash.

Stewart Jamieson from Durham University in England and his colleagues made the discovery by looking for subtle changes in the ice sheet's surface shapes, developed as a result of ice flowing over diverse topography.

«Loss of ice shelves surrounding the Antarctic continent could have a major effect on the rate of ice flow off the continent,» Scambos notes.

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.

Seventy billion tons of ice flows out of the Totten Glacier, into the ocean, every year.

Caption: Visualisation of ice flow in the Antarctic ice sheet model PISM - PIK.

Help get the penguin to safety on different numbers of ice flows.

I keep seeing mention of flow under ice in Antarctica, and am wondering if you refer to Greenland conditions or to a more basic understanding of ice flow globally.

Michael Lemonick at Climate Central writes on new research finding it's unlikely that the recent surge of ice flowing into the sea from Greenland's glaciers is the new normal (the work syncs with earlier analysis by Tad Pfeffer of the University of Colorado):

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.

Here in answer to him is an animation from NASA's Echo2 project, showing the delicate and thin blue layers of the ice flows:

This allowed the complete pattern of ice flow to be mapped, revealing that the regions glaciers are now pouring an additional 15 cubic kilometres of ice into the oceans each year compared to the 1990s.

The ice stream's speed - up and near - doubling of ice flow from land into the ocean has increased the rate of sea level rise by about.06 millimeters (about.002 inches) per year, or roughly 4 percent of the 20th century rate of sea level increase.

So, I'm not extremely versed with glacial ice, but what we're talking about is sheathing of ice because of ice flow, not melting, correct?

Finally, we provide simple analytical expressions for the mean speed of the ice flow as a function of the channel shape, the properties of the ice, and the wind and water stresses along the channel.

The map of ice flow speed revealed a complex pattern where fast glacier flow near the coast extended well inland in narrow tributary bands.

It points to the importance of future dynamical modeling of ice flow.

By combining regional temperature projections with detailed maps of the underlying topography, then adding in the physics of ice flow, the authors project not only that the glaciers of Western Canada will lose at least 70 percent of their volume by 2100 — a number more or less in keeping with current projections — but show exactly how every individual glacier will shrink.

Ice shelves buttress the glaciers behind them, modulating the speed at which these rivers of ice flow into the ocean.

Because the claims are based on speculations about ice sheet collapse, which as far as I know are based on unrealistic 2D models of ice flow (length + depth — intended for glaciers rather than ice sheets, I think).
