Surface mass balance (SMB) provides mass input to the surface of the Antarctic and
Greenland Ice Sheets and therefore comprises an important control on ice sheet mass …

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 …

Surface melt and subsequent firn air depletion can ultimately lead to disintegration of
Antarctic ice shelves, causing grounded glaciers to accelerate and sea level to rise. In the …

Antarctica's ice shelves provide resistance to the flow of grounded ice towards the ocean. If
this resistance is decreased as a result of ice shelf thinning or disintegration, acceleration of …

Ice shelves play a vital role in regulating loss of grounded ice and in supplying freshwater to
coastal seas. However, melt variability within ice shelves is poorly constrained and may be …

Floating ice shelves of fast-flowing ice streams are prone to rift initiation and calving
originating along zones of rapid shearing at their margins. Predicting future ice-shelf …

Antarctica's ice shelves are thinning at an increasing rate, affecting their buttressing ability.
Channels in the ice shelf base unevenly distribute melting, and their evolution provides …

The East Antarctic ice sheet is likely more stable than its West Antarctic counterpart because
its bed is largely lying above sea level. However, the ice sheet in Dronning Maud Land, East …

Ice shelves buttress ice streams and glaciers, slowing the rate at which they flow into the
ocean. When this buttressing is reduced, either through increased melt or calving, the …

Ice-shelf channels are long curvilinear tracts of thin ice found on Antarctic ice shelves. Many
of them originate near the grounding line, but their formation mechanisms remain poorly …
