Subglacial lakes are repositories of ancient climate conditions, provide habitats for life and
modulate ice flow, basal hydrology, biogeochemical fluxes and geomorphic activity. In this …

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 …

Abstract The National Aeronautics and Space Administration (NASA)'s Operation IceBridge
(OIB) was a 13‐year (2009–2021) airborne mission to survey land and sea ice across the …

We present a new bed elevation dataset for Greenland derived from a combination of
multiple airborne ice thickness surveys undertaken between the 1970s and 2012. Around …

This paper presents a radar sensor package specifically developed for wide-coverage
sounding and imaging of polar ice sheets from a variety of aircraft. Our instruments address …

Abstract Knowledge of Antarctica's sedimentary basins builds our understanding of the
coupled evolution of tectonics, ice, ocean, and climate. Sedimentary basins have properties …

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 …

Information about glacier volume and ice thickness distribution is essential for many
glaciological applications, but direct measurements of ice thickness can be difficult and …

The ice flux divergence of a glacier is an important quantity to examine because it
determines the rate of temporal change of its thickness. Here, we combine high‐resolution …
