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 …

Abstract The Radar for Europa Assessment and Sounding: Ocean to Near-surface
(REASON) is a dual-frequency ice-penetrating radar (9 and 60 MHz) onboard the Europa …

Subglacial conditions of large polar ice sheets remain poorly understood, despite recent
advances in satellite observation. Major uncertainties related to basal conditions, such as …

Thwaites Glacier is one of the largest, most rapidly changing glaciers on Earth, and its
landward-sloping bed reaches the interior of the marine West Antarctic Ice Sheet, which …

Recent results from the Mars Advanced Radar for Subsurface and Ionosphere Sounding
(MARSIS) instrument have been interpreted as evidence of subsurface brine pooled …

Heterogeneous hydrologic, lithologic, and geologic basal boundary conditions can exert
strong control on the evolution, stability, and sea level contribution of marine ice sheets …

Finding suitable potential sites for an undisturbed record of million-year old ice in Antarctica
requires slow-moving ice (preferably an ice divide) and basal conditions that are not …

A clean hot-water drill was used to gain access to Subglacial Lake Whillans (SLW) in late
January 2013 as part of the Whillans Ice Stream Subglacial Access Research Drilling …

The flow of ice is temperature‐dependent, but direct measurements of englacial temperature
are sparse. The dielectric attenuation of radio waves through ice is also temperature …

Sea-level rise projections rely on accurate predictions of ice mass loss from Antarctica.
Climate change promotes greater mass loss by destabilizing ice shelves and accelerating …
