MAGPIE The MAGPIE Project (2019-2023)

Magnetotelluric Analysis for Greenland and Postglacial Isostatic Evolution

Funded by the Research Council of Norway.


  • Perform the first ever magnetotelluric (MT) survey of the Greenland Ice Sheet.
  • Constrain lateral viscosity variations in the mantle beneath Greenland using MT data.
  • Develop 3D numerical models of postglacial rebound in Greenland that include lateral variations in mantle viscosity.
  • Remove deformation caused by postglacial rebound from geodetic observations to constrain patterns and amplitudes of modern-day ice mass loss in Greenland.

Datasets, Codes, and Models

Various research output that we have made available for general use.

Rotational Feedback for SELEN

Masters student Robert Hartmann developed an update to SELEN, which is a public code for solving the sea level equation. As documented by Hartmann et al. [2020], this update adds rotational feedback to the SELEN solution for sea level.

Sea level variations due to reservoir impoundment Sea Level Response to Surface Loads

Surface loads deflect the Earth's solid and sea surfaces, causing lateral variations in rates of sea level change. We have computed the sea level response to:

Basaltic Volcanism Baslatic Volcanism Locations

We have compiled a database of the locations of baslatic volcanism in continental environments. This work is documented in Conrad et al. [2011] and includes the locations of:

mantle flow Mantle Flow Model and calcpi Code

We have developed a model of the flow field within the Earth's present-day mantle [Conrad and Behn, 2010]. The model is constrained by observations of seismic anisotropy. To predict anisotropy from the flow model, we developed the "calcpi" code [Conrad et al., 2007] that computes the Infinite Strain Axis (ISA) associated with the mantle flow field.

Dynamic Topography Dynamic Topography Model

We have developed a model for present-day dynamic topography at the Earth's surface, as supported by mantle flow [Conrad and Husson, 2009].

Subduction Parameters Subduction Parameters

We have compiled a database of parameters describing subduction zone transects around the world. These parameters are sufficient to compute forces associated with slab pull and plate bending [Wu, Conrad et al., 2008].

Fossil Spreading Fossil Seafloor Spreading Rates

By computing gradients of seafloor ages, we have compiles a model of fossil spreading rates for the global seafloor [Conrad and Lithgow-Bertelloni, 2007].

Lithospheric Thickness Lithosphere Thickness Model

We have estimated lateral variations lithospheric thickness [Conrad and Lithgow-Bertelloni, 2006].
