Antarctic Elevation Change from 1992 to 1996

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...

Zusammenfassung:	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.
