The Impact of a 3-D Earth Structure on Glacial Isostatic Adjustment in Southeast Alaska Following the Little Ice Age

In Southeast Alaska, extreme uplift rates are primarily caused by glacial isostatic adjustment (GIA), as a result of ice thickness changes from the Little Ice Age to the present combined with a low-viscosity asthenosphere. Previous GIA models adopted a 1-D Earth structure. However, the actual Earth structure is likely more complex due to the...
