Sentences with phrase «on ice sheet elevation»

Not exact matches

Regions of higher elevation on the ice sheet do not receive an abundance of precipitation, and Summit Station tends to be drier still.

Box pointed to nearly ice - sheet - wide melting on Greenland, with extensive surface melting documented for first time at the highest elevations of ice sheet, and the longest melt season since satellite observations began in 1979.

For the last phase, from 2003 to 2010, the researchers relied on laser altimetry and radar altimetry to estimate the ice elevation and map the receding ice sheet.

One feedback that I have only rarely heard discussed is the effect that the drop in elevation of, for example, the Greenland Ice sheet will have on the melting at the top.

Along with David Schilling, I had developed a model to reconstruct former ice sheets with ice elevations based on the strength of ice - bed coupling determined by glacial geology.

Over the long - term, melting of the West Antarctic Ice Sheet could yield as much as 10 to 14 feet of global average sea level rise, with local sea level rise varying considerably depending on land elevation trends, ocean currents and other factors.

On Greenland, the present very coldest temperatures are as low as -30 degC, those temps being on the highest elevations of Ice SheeOn Greenland, the present very coldest temperatures are as low as -30 degC, those temps being on the highest elevations of Ice Sheeon the highest elevations of Ice Sheet.

«IceBridge has collected so much data on elevation and thickness that we can now do analysis down to the individual glacier level and do it for the entire ice sheet,» said Michael Studinger, IceBridge project scientist at NASA's Goddard Space Flight Center in Greenbelt, Md. «We can now quantify contributions from the different processes that contribute to ice loss.»

Based on ice - sheet model simulations consistent with elevation changes derived from a new Greenland ice core, the Greenland ice sheet very likely contributed between 1.4 m and 4.3 m sea level equivalent, implying with medium confidence a contribution from the Antarctic ice sheet to the global mean sea level during the last interglacial period.
