Sentences with phrase «glacier glacial flow»

Not exact matches

Radar measurements and models of Earthly glacial ice flows led researchers to conclude that the glaciers spotted on Mars from orbiters contain nearly 150 billion cubic meters of water.

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.

Also, there is some evidence that what happens at the front of such glaciers can affect the «back» (inland) parts of the glaciers increasing glacial flow toward the ocean.

Since glacial ice deforms like very slow putty, the steepening of the glacier would have caused the more mobile, middle section to flow pick up speed.

In addition to the postglacial sinking due to the glacial «forebulge» slowly flowing back into the «hole» left by the glaciers, a broad zone from southern England through the Netherlands into northern Germany and Poland has been slowly sinking all through the Quaternary.

Using simple observations of scratches and the «plucking» of rocks on the downside of glacial flow directions, I concluded on my second day in the field that the glaciers moved not towards the competitor's property but FROM the competitor's property.

The glaciers flowing from the steep mountains on the tip of the South American continent, have been one of the most visible of global glacial retreats.

But a new discussion paper, «The role of glaciers in stream flow from the Nepal Himalaya,» (Alford and Armstrong, The Cryosphere Discuss., 4, 469 - 494, 2010) concludes that glacial runoff contributes only about 4 % to the total annual stream flow of the Ganges system; the great majority is contributed by monsoon rains.

The observed effects of cryosphere reduction include modification of river regimes due to enhanced glacial melt, snowmelt advance and enhanced winter base flow; formation of thermokarst terrain and disappearance of surface lakes in thawing permafrost; decrease in potential travel days of vehicles over frozen roads in the Arctic; enhanced potential for glacier hazards and slope instability due to mechanical weakening driven by ice and permafrost melting; regional ocean freshening; sea - level rise due to glacier and ice sheet shrinkage; biotic colonisation and faunal changes in deglaciated terrain; changes in freshwater and marine ecosystems affected by lake - ice and sea - ice reduction; changes in livelihoods; reduced tourism activities related to skiing, ice climbing and scenic activities in cryospheric areas affected by degradation; and increased ease of ship transportation in the Arctic.

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).
