Accurately monitoring and predicting the evolution of the West Antarctic Ice Sheet via secular changes in the Earth’s gravity field requires knowledge of the underlying upper mantle viscosity structure. Published seismic models show the West Antarctic lithosphere to be ∼70–100 km thick and underlain...
