Sentences with phrase «how glaciers flow»

«There's a big effort to model how glaciers flow in Antarctica, and these models need a landscape over which glaciers can flow,» Thomson told OurAmazingPlanet.

The findings of this research give a clearer picture of how glacier flow affects the Greenland Ice Sheet and shows that this dynamic process is dominated by a small number of glaciers.

Not exact matches

Howat and his team were able to figure this out by creating high - resolution topographic models of the glaciers and their boundaries, as well as a numerical model of exactly how much water was flowing off these coastal glaciers and ice caps — technology that wasn't available back in 1996.

Now, by studying glaciers from Tibet to the Arctic islands of the Svalbard archipelago in Norway, researchers are starting to understand why some glaciers swing between extremes of stagnation and crushing flow, and how surges may be predicted.

Changes in mass, rather than height, control how the ice shelves and associated glaciers flow into the ocean,» Paolo said.

The team looked at how meltwater from two small mountain glaciers flowed through the system and influenced the mountain streams, rivers and groundwater all year long.

Glaciers around the world are melting and contributing to sea level rise, but scientists still don't quite understand how exactly glaciers give birth to icebergs as they flow into the ocean and lGlaciers around the world are melting and contributing to sea level rise, but scientists still don't quite understand how exactly glaciers give birth to icebergs as they flow into the ocean and lglaciers give birth to icebergs as they flow into the ocean and lose ice.

Those calculations were made without detailed maps of how water flows at the glacier's underbelly.

Reinhard was awarded for his work in investigating how the potential disintegration of Antarctic floating ice shelves could contribute to increased ice flow from inland glaciers, and a resulting rise in global sea levels.

Focus of Study Glacier and rock interactions: how the underlying rock influences glacier flow and how past glaciations have affected tectonics.

Drews was awarded for his work in investigating how the potential disintegration of Antarctic floating ice shelves could contribute to increased ice flow from inland glaciers, and a resulting rise in global sea levels [5].

REVIEW: Water Science for Schools examines a wealth of water topics such as water properties, how much water is there on earth and where, how water quality and stream flow are measured, the water and water - use cycles, national maps showing how water is used by state, surface and ground water, pesticides in ground water, aquifers, and glaciers and icecaps.

«They calculated how fast glaciers would have to flow in order to raise sea level by a given number of meters and then considered whether those flow rates were plausible or even physically possible.

Until now, though, most of the focus has been on ice sheet dynamics — how quickly Greenland's glaciers are flowing into the sea.

How fast will glaciers melt and how will this accelerated melting affect the region's river floHow fast will glaciers melt and how will this accelerated melting affect the region's river flohow will this accelerated melting affect the region's river flows?

So in fact three variables determine how the meltwater at the bed organizes itself: the melting rate at void walls, the opening rate due to down - glacier flow, and the closure rate due to the pressure difference at void walls, the latter depending in turn on the rate of delivery of surface meltwater.

Other factors being investigated are the impact of lakes on Greenland's glacial surfaces, the effect of dust and soot on the ice sheet (which have been shown to have a major impact in accelerating melting in Himalayan glaciers), and how surface meltwater affects ice flow into the ocean (previous research has shown that is speeds it and is increased by short term weather extremes).
