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 …

The Antarctic ice sheet has been losing mass over past decades through the accelerated
flow of its glaciers, conditioned by ocean temperature and bed topography. Glaciers …

Over the past two decades, ice loss from the Greenland ice sheet (GrIS) has increased
owing to enhanced surface melting and ice discharge to the ocean,,,–. Whether continuing …

Ice stream evolution is a major uncertainty in projections of the future of the Greenland and
Antarctic Ice sheets. Accurate simulation of ice stream evolution requires an understanding …

Ice sheets reshape Earth's surface. Maps of the landscape formed by past ice sheets are our
best tool for reconstructing historic ice sheet behavior. But models of glacier erosion and …

The geometry of the sea floor immediately beyond Antarctica's marine-terminating glaciers is
a fundamental control on warm-water routing, but it also describes former topographic …

Abstract Bedforms of Thwaites Glacier, West Antarctica both record and affect ice flow, as
shown by geophysical data and simple models. Thwaites Glacier flows across the tectonic …

Abstract Seismic measurements on Thwaites Glacier show a spatially variable bed
character, with implications for ice-sheet stability. The West Antarctic Ice Sheet is losing …

The Northeast Greenland Ice Stream (NEGIS) is an important dynamic component for the
total mass balance of the Greenland ice sheet, as it reaches up to the central divide and …

This paper addresses the effect of fractures within crystalline bedrock on glacial erosion
processes in fast flowing hard bed glacier environments. In particular, we examine (i) …
