Antarctic Elevation Change from 1992 to 1996 

Duncan J. Wingham, * Andrew J. Ridout, Remko Scharroo, Robert J. Arthern, C. K. Shum

Satellite radar altimeter measurements show that the average elevation of the Antarctic Ice Sheet interior fell by 0.9 ± 0.5 centimeters per year from 1992 to 1996. If the variability of snowfall observed in Antarctic ice cores is allowed for, the mass imbalance of the interior this century is only -0.06 ± 0.08 of the mean mass accumulation rate.
