Relationship between glacial isostatic adjustment and gravity perturbations observed by GRACE

Purcell, Anthony; Dehecq, A.; Tregoning, Paul; Potter, Emma-Kate; McClusky, Simon; Lambeck, Kurt


The Gravity Recovery and Climate Experiment space gravity mission provides one of the principal means of estimating present-day mass loss occurring in polar regions. Extraction of the mass loss signal from the observed gravity changes is complicated by the need to first remove the signal of ongoing glacial isostatic adjustment (GIA) since the Last Glacial Maximum. This can be problematic in regions such as Antarctica where the GIA models are poorly constrained by observation and their accuracy...[Show more]
