Growth of Greenland Ice Sheet: Measurement

Measurements of ice-sheet elevation change by satellite altimetry show that the Greenland surface elevation south of 72° north latitude is increasing. The vertical velocity of the surface is 0.20 ± 0.06 meters per year from measured changes in surface elevations at 5906 intersections between Geosat...

Description
Summary:Measurements of ice-sheet elevation change by satellite altimetry show that the Greenland surface elevation south of 72° north latitude is increasing. The vertical velocity of the surface is 0.20 ± 0.06 meters per year from measured changes in surface elevations at 5906 intersections between Geosat paths in 1985 and Seasat in 1978, and 0.28 ± 0.02 meters per year from 256,694 intersections of Geosat paths during a 548-day period of 1985 to 1986.
