Free air gravity anomalies associated with glacial isostatic disequilibrium: load history effects on the inference of deep mantle viscosity / J.X. Mitrovica, W.R. Peltier.

Title: Free air gravity anomalies associated with glacial isostatic disequilibrium: load history effects on the inference of deep mantle viscosity / J.X. Mitrovica, W.R. Peltier.
Author(s): Mitrovica, J. X.
Peltier, W. R.
Date: 1991.
In: Geophysical Research Letters. (1991.), Vol. 18(2) (1991)
Abstract: Free air gravity anomaly over Hudson Bay is well correlated with topography of Laurentide ice sheet and is used, consequently, in inferring deep mantle viscosity. Here, sensitivity of inference on assumed space and time dependent geometry of ice load is examined. Results suggest that variations in load history during last deglaciation phase of current ice age can alter preferred deep mantle viscosity by orders of magnitude.
