Radar sounding is a powerful geophysical approach for characterizing the subsurface
conditions of terrestrial and planetary ice masses at local to global scales. As a result, a wide …

Locally grounded features in ice shelves, called ice rises and rumples, play a key role
buttressing discharge from the Antarctic Ice Sheet and regulating its contribution to sea level …

The basal thermal state of an ice sheet (frozen or thawed) is an important control upon its
evolution, dynamics, and response to external forcings. However, this state can only be …

Accurate representation of the viscous flow of ice is fundamental to understanding glacier
dynamics and projecting sea-level rise. Ice viscosity is often described by a simple but …

Compression of snow at low strain rates governs the natural densification of snow and firn
on Earth. Different deformation mechanisms (eg, grain boundary sliding and dislocation …

The ApRES (autonomous phase-sensitive radio-echo sounder) instrument is a robust,
lightweight and relatively inexpensive radar that has been designed to allow long-term …

In times of warming in polar regions, the prediction of ice sheet discharge is of utmost
importance to society, because of its impact on sea level rise. In simulations the flow rate of …

Understanding the flow of ice in glaciers and polar ice sheets is of increasing relevance in a
time of potentially significant climate change. The flow of ice has hitherto received relatively …

Snow stratigraphy and water percolation are key contributing factors to avalanche formation.
So far, only destructive methods can provide this kind of information. Radar technology …

Abstract Purpose of Review This paper reviews the recent literature on numerical modelling
of the dynamics of the Greenland ice sheet with the goal of providing an overview of …
