Structural weaknesses in ice mélange revealed by high resolution ICEYE SAR imagery

Journal of Glaciology
The mixture of icebergs and sea ice in tidewater glacier fjords, known as ice mélange, is postulated to impact iceberg calving directly through physical buttressing and indirectly through freshwater fluxes altering fjord circulation. In this contribution,

Spatial Variability and Drivers of Salt Marsh Cliff Erosion in the Dutch Wadden Sea: From Observation to Simulation

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.
Abstract Lateral erosion of salt marshes via cliff retreat is a primary cause of global marsh loss, driven by interactions between hydrodynamics, sediment, and vegetation. While previous studies show a linear relationship between wave power and cliff retreat, models based on this relationship are largely unvalidated for short‐term (sub‐yearly) and ...

Reconstructing Glacier Surge Kinematics Using a Numerical Ice‐Flow Model Applied to the Dusty Glacier, St. Elias Mountains, Canada

Geophysical Research Letters
Long‐term records of the flow patterns and dynamics of surge‐type glaciers improve our understanding of their underlying dynamic processes, and are critical to better resolve their contribution to a changing cryosphere.

Basal Force Probability Distributions in Thin‐Layer Granular Flows

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.
Abstract Extreme geophysical flows, such as granular and debris flows, can significantly shape the landscape in steep lands and generate seismic signals that can be recorded over long distances. However, direct field measurements needed to constrain the granular physics remain difficult due to the damage potential of those flows.

Surface Mineralogy and Hydrological Controls on “Hotspots” of Dust Emission at Etosha Pan, Namibia

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.
Abstract Ephemeral lake beds are globally significant sources of atmospheric mineral dust aerosols, yet emissions from these landforms exhibit considerable spatial and temporal variability. The complex interactions between climatic drivers and surface properties that govern dust emissions remain poorly understood, contributing to uncertainties in model

Glacier Mass Balance Modeling Using a Long Short‐Term Memory Network

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Glacier mass balance (MB) is a key indicator of climate change and a central driver of glacier evolution, yet most glaciers worldwide lack long‐term in situ measurements. For estimating glacier MB, data‐driven models provide a complementary alternative to traditional numerical approaches by learning empirical relationships between climate ...

A Vast Valley Network Beneath the Greenland Ice Sheet

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Mapping subglacial topography along the margin of the Greenland Ice Sheet was revolutionized by reconciling measurements of ice thickness and surface velocity using the principle of mass conservation. Despite evidence that many subglacial valleys resolved by that method extend upstream, it cannot be applied to the ice sheet's slower‐flowing ...

Principles of Structural Glaciology [Book Review]

, 1965
The title of this volume, although appropriate, is not really indicative of its content. It becomes more than a book on structural glaciology through its detailed treatment of many facets of glaciology, which the author defines as the science of natural ice in all its aspects.

Influence of Glaciological Structures on the Spatial Distribution of Cryoconite Holes, Northern Victoria Land, East Antarctica

Journal of Geophysical Research: Earth Surface
Abstract Three blue‐ice areas in the upper reaches of Rennick Glacier, East Antarctica, are investigated using satellite remote sensing to assess the influence of meso‐ to large‐scale glaciological structures on cryoconite hole distributions.
