Characterisation and multiphase flow modelling of a rock avalanche turned into a supraglacial debris flow: Insights from Mt Job, British Columbia, Canada

Earth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
Photographs before (left) and after (right) the May 2023 landslide in Mt Job, Mount Meager Volcanic Complex, British Columbia, Canada. The initial rock avalanche impacted the glacier, producing a 4.5‐km‐long debris flow that ran over it and down the valley.

Coupling Debris Transport to 3D Higher‐Order Ice Flow Dynamics to Model the Behavior and Climate Change Response of Debris‐Covered Glaciers

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.
Abstract We use a three‐dimensional time‐dependent glacier model that couples higher‐order ice flow dynamics with multi‐dimensional englacial and supraglacial debris transport to investigate the behavior of debris‐covered glaciers and their response to climate change.

Mapping Debris-Covered Glaciers Using High-Resolution Imagery (GF-2) and Deep Learning Algorithms

Remote Sensing
Glacier inventories are fundamental in understanding glacier dynamics and glacier-related environmental processes. High-resolution mapping of glacier outlines is lacking, although high-resolution satellite images have become available in recent decades ...

Beyond Rock Glaciers: Investigating Meltwater Contribution and Water Quality in High‐Mountain Springs From Different Landforms

Hydrological Processes, Volume 40, Issue 4, April 2026.
We investigated the water chemistry of springs from different landforms in high‐elevation Alpine catchments. Only in predisposing lithological settings, springs from landforms most likely influenced by ice had a poor water quality with high dissolved concentrations of metals.

Lichen Growth on Supraglacial Debris and its Implications for Lichenometric Studies [PDF]

Journal of Glaciology, 1978
AbstractLichens were found growing on some of the supraglacial debris of six small, active, retreating valley glaciers in southern Norway. The circumstances permitting their growth are discussed, as is the possibility of their surviving pro-glacial deposition under current and past conditions.

Stratigraphic evidence for modern‐like glacier extents in south‐central Alaska within the last glacial period (MIS 3)

Boreas, Volume 55, Issue 2, Page 476-502, April 2026.
The last (Wisconsinan) glacial period was punctuated in North America by two glacial maxima, known as the Early and Late Wisconsinan glaciations. In Alaska, these maxima and their subsequent retreats have been the object of dating efforts to reconstruct local climatic events and compare them to global trends.

Spatial, seasonal and interannual variability of supraglacial ponds in the Langtang Valley of Nepal, 1999–2013

Journal of Glaciology, 2017
Supraglacial ponds play a key role in absorbing atmospheric energy and directing it to the ice of debris-covered glaciers, but the spatial and temporal distribution of these features is not well documented.

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 ...

Revealing the Internal Structure of Mars‐Analog Glaciers From Drone‐Based Radar Sounding

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Martian debris‐covered glaciers (DCGs) contain large quantities of water ice beneath a protective layer of rock and dust. Properties of the overlying regolith such as density and depth to ice are critical parameters for guiding in situ resource utilization (ISRU) of water and coring missions targeting potential habitats.

Thickness estimation of supraglacial debris above ice cliff exposures using a high-resolution digital surface model derived from terrestrial photography

Journal of Glaciology, 2017
The thickness of supraglacial debris cover controls how it impacts the ablation rate of underlying glacier ice, yet this quantity remains challenging to measure, particularly at glacier scales.
