Antarctic subglacial hydrology: application of CryoSat-2 swath altimetry to the study of active subglacial lakes [PDF]
The Antarctic ice sheet is primarily drained by fast-flowing ice streams and glaciers, with water at the ice sheet's base believed to be a crucial factor in maintaining their high velocity through reduced friction.

Martian Proton Albedo as Signature of Near‐Surface Water
Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.Abstract Understanding the Martian soil water budget is crucial not only for in situ resource utilization in future human missions to Mars, but also for reconstructing the geological and climatic history of the planet, as well as to assess the potential of ancient or even present microbial life.

A wireless multi-sensor subglacial probe: design and preliminary results
, 2006 This paper introduces a new way to investigate in situ processes, the wireless multi-sensor probe, as part of an environmental sensor network. Instruments are housed within a 'probe' which can move freely and so behave like a clast.

Insights into glacial processes from micromorphology of silt-sized sediment [PDF]
The CryosphereSilt-rich meltwater plume deposits (MPDs) analyzed from marine sediment cores have elucidated relationships that are clearly connected, yet difficult to constrain, between subglacial hydrology, ice-marginal landforms, and grounding-zone retreat patterns ...

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract Since the 1970s, Pine Island Glacier has exhibited thinning, acceleration, and retreat. During the last decade, the ice shelf has undergone major geometric changes, whilst the quantity and temperature of modified Circumpolar Deep Water on the Amundsen Sea continental shelf fluctuated significantly.

Glacial erosion: status and outlook
Annals of Glaciology, 2019 Glacier-erosion rates range across orders of magnitude, and much of this variation cannot be attributed to basal sliding rates. Subglacial till acts as lubricating ‘fault gouge’ or ‘sawdust’, and must be removed for rapid subglacial bedrock erosion. Such

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract Interactions among faulting, earthquakes, and eruptions are fundamental to plate tectonics and hazard forecasting yet rarely observed along mid‐ocean ridges. On Iceland's Reykjanes Peninsula, seismotectonic–volcanic unrest resumed after nearly 800‐year hiatus, providing an opportunity to observe these interactions during 2021–2025 activity. By

Large-scale Modelling of Subglacial Hydrology [PDF]
, 2018 Subglacial hydrology is a key component in ice sheet dynamics and controls the sliding of ice sheets. Modelling the integrated system between ice dynamics and subglacial hydrology is essential for understanding current changes in the system and ...

Eurasian ice-sheet dynamics and sensitivity to subglacial hydrology [PDF]
, 2017 Ice-stream dynamics are strongly controlled by processes taking place at the ice/bed interface where subglacial water both lubricates the base and saturates any existing, underlying sediment. Large parts of the former Eurasian ice sheet were underlain by

International Journal of Digital EarthThe western Kunlun main peak region is among the areas in High Mountain Asia where surge-type glaciers are highly concentrated. Here, we analyse the surging characteristics of the eastern and western branches of the Western Kunlun Glacier and the factors
