The southern tip of spitsbergen that document a long history of methane venting in the region 4) when the rate of isostatic uplift outpaced eustatic sea-level rise, in contrast to proposed scenarios that attribute methane venting to anthropogenic warming. Post-glacial rebound and isostatic depression are phases of glacial isostasy (glacial isostatic adjustment, glacioisostasy), the deformation of the earth's crust in response to changes in ice mass distribution.
