Resolving the internal and basal geometry of ice masses using imaging phase-sensitive radar

Journal of Glaciology, 2018
The phase-sensitive radio-echo sounder (pRES) is a powerful new instrument that can measure the depth of internal layers and the glacier bed to millimetre accuracy.

Real‐Time Ground Deformation Records of Coastal Cliff Failures in San Diego County, California

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Coastal cliff failures pose significant risks to public safety and coastal infrastructure, especially in southern California. We deployed a suite of continuous geophysical sensors to investigate failure processes and precursory behaviors at three coastal clifftop sites in San Diego County: San Elijo State Beach and two locations in Del Mar ...

O Levee, Where Art Thou? Measuring the Abundance of Natural River Levees Across the Contiguous USA

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Most—if not all—alluvial rivers experience overbank floods. On some rivers, these floods form natural levees, whereas on others they do not. Existing theories for how levees form on riverbanks rely on the physics of sediment transport across the channel margin, but applying them to real rivers does not yield good predictions of why one river ...

Chemical and isotopic switching within the subglacial environment of a high Arctic glacier. [PDF]

, 2006
Natural environmental isotopes of nitrate, sulphate and inorganic carbon are discussed in conjunction with major ion chemistry of subglacial runoff from a High Arctic glacier, Midre Lovénbreen, Svalbard. The chemical composition of meltwaters is observed

Testing Nodal Point Relations by Tracking Sediment Through a Bifurcation on the Jefferson River, MT, USA

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract River bifurcations control water and sediment distribution in fluvial systems, but the physical mechanisms governing sediment partitioning remain poorly validated in natural rivers. We present a comprehensive field test of nodal point relations using radio frequency identification (RFID) tracking of 376 gravel clasts through a meandering river

Quantifying Seasonal Deformation Signals Using InSAR and Groundwater Models in the Mississippi River Delta, Baton Rouge, Louisiana

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Seasonal land motion can be caused by processes above or below Earth's surface, often linked to natural changes in the hydrological cycle. In coastal deltaic systems, the coupling of water level changes between rivers and aquifers may cause significant surface deformation, but this process is poorly understood.

Unravelling the evolution of the Frébouge polygenetic cone in Val Ferret (Mont Blanc Massif)

Boreas, Volume 55, Issue 2, Page 454-475, April 2026.
Proglacial settings in the Alps are typically polygenetic, often characterized by a complex and discontinuous interplay between glacial, fluvial and gravitational processes. These processes yield high volumes of sediments, which usually exceed their transportation capacity.

Glacier‐Atmosphere Interactions and Feedbacks in High‐Mountain Regions ‐ A Review

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Mountain glaciers are among the natural systems most vulnerable to climate change. However, their interactions with the atmosphere are complex and not fully understood. These interactions can trigger rapid adjustments and climate feedbacks that either amplify or attenuate atmospheric signals, influencing both glacier response and large‐scale ...
