Many outer solar system bodies are thought to harbor liquid water oceans beneath their ice
shells. This article first reviews how such oceans are detected. We then discuss how they …

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 …

Greenland's bed topography is a primary control on ice flow, grounding line migration,
calving dynamics, and subglacial drainage. Moreover, fjord bathymetry regulates 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 …

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 …

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

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 shelves control sea-level rise through frictional resistance, which slows the seaward flow
of grounded glacial ice. Evidence from around Antarctica indicates that ice shelves are …

We present a topographic digital elevation model (DEM) for Princess Elizabeth Land (PEL),
East Antarctica. The DEM covers an area of∼ 900 000 km 2 and was built from radio-echo …

Antarctica's subglacial lakes have two end member geophysical expressions: as
hydraulically flat, radar reflective regions highlighted in ice surface topography and radar …
