Effect of isostatic rebound on modelled ice volume variations during the last 200 kyr

Crucifix, Michel; Loutre, Marie-France; Berger, Andre; Lambeck, Kurt

Description

Deformation of the lithosphere under an ice load can be approximated using the hypothesis of local damped isostasy. This simple formulation has been systematically compared with a three-dimensional model of the crust-mantle system for simple ice-load scenarios with a period in the range 20-100 kyr. The comparison enables us to introduce the concepts of effective upper mantle density and effective relaxation time into the isostatic model for the response of the Earth to the ice sheets. These...[Show more]
