Aircraft laser-altimeter surveys over northern Greenland
in 1994 and 1999 have been coupled with previously reported data from
southern Greenland to analyze the recent mass-balance of the Greenland
Ice Sheet. Above 2000 meters elevation, the ice sheet is in balance on
average but has some regions of local thickening or thinning. Thinning
predominates at lower elevations, with rates exceeding 1 meter per year
close to the coast. Interpolation of our results between flight lines
indicates a net loss of about 51 cubic kilometers of ice per year from
the entire ice sheet, sufficient to raise sea level by 0.13 millimeter
per year--approximately 7% of the observed rise.
