Not exact matches

The Pine Island Glacier expedition deployed multiple, unique sensor packages, developed by NPS Research Professor Tim Stanton, through 500 meters of solid ice to determine exactly how quickly warm water was melting the massive glacier from beneath.

Using satellites, the researchers determined that «bottom melt rates experienced by large outlet glaciers near their grounding lines are far higher than generally assumed.»

Re GRACE glacier measurements, David H. Bromwich & Julien P. Nicolas report a major reduction in uncertainty of glacier melting — they can now identify that the TREND is negative, but not yet determine the magnitude!

The melt rate is determined from repeat probing and stakes drilled into the glacier recording the actual surface melt.

Annual net balance on eight North Cascades glaciers during the 1984 - 1994 period has been determined by measurement, of total mass loss from firn and ice melt and, of residual snow depth at the end of the summer season.

Now he's embarking on a joint project with the eminent climatologist V. Ramanathan of the Scripps Institute of Oceanography and Eric Wilcox, an atmospheric scientist at NASA, to determine exactly how quickly some benchmark glaciers in the Indian Himalayas are melting.

Finally, climate scientist Eric Steig and his research team have determined that the natural conditions and phases of tropical Pacific waters are the real cause of Antarctica's coastal glaciers» melting.

Thus the topography of the coastal shelves and depth of submerged glacier grounding points determines the impact of upwelled CDW and limits extreme basal melting to a relatively few locations as illustrated by the red and orange areas in the figure below (from Depoorter 2013)..

While glaciers melt under the pressure of greenhouse gas emissions, Kearney is determined to reduce her part in climate change by offsetting all Olympic training travel with NativeEnergy.

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.

re: «A complementary method for determining and / or evaluating global sea level rise is a budget analysis that adds together the cumulative effect of the main contributors to sea level rise: thermal expansion, melting of ice in glaciers, ice loss from the Greenland and the Antarctic ice sheets, and changes in land water storage.»

A complementary method for determining and / or evaluating global sea level rise is a budget analysis that adds together the cumulative effect of the main contributors to sea level rise: thermal expansion, melting of ice in glaciers, ice loss from the Greenland and the Antarctic ice sheets, and changes in land water storage.

They determined, however, that this volume had now increased by a further 3 cubic miles each year, prompted by an acceleration in the rate at which the ice caps and glaciers are melting.Unlike what many other scientists have said — including, most prominently, NASA's James Hansen (who believes that a rise in 17 inches by 2100 will be mainly precipitated by the melting of ice sheets)-- the authors of this study believe that the loss of ice from glaciers and ice caps will account for the majority of the expected rise in sea levels.

The scientists used satellite monitoring to determine the contribution of all land - based ice (except for Greenland and Antarctica's huge ice sheets) to rising sea levels and found that the volume of ice melting into the sea each year from ice caps and glaciers was 100 cubic miles (or 417 cubic km).
