MAGPIE – Magnetotelluric Analysis for Greenland and Postglacial Isostatic Evolution

The MAGPIE project seeks to develop new constraints on uplift patterns in and around Greenland associated with past and present ice melting. For this, we are collecting magnetotelluric (MT) data from Greenland’s interior, which we then use to constrain viscosity variations beneath Greenland.

Such variations may have resulted from heat added beneath Greenland by the Iceland Plume. We are developing numerical models of a plume hitting Greenland’s lithosphere as well as a new numerical modeling technique for glacial isostatic adjustment (GIA) that can accommodate large viscosity variations. We will use this code to predict GIA uplift patterns associated viscosity variations beneath Greenland.
