Debris-covered glacier systems and associated glacial lake outburst flood hazards: challenges and prospects

AE Racoviteanu, L Nicholson, NF Glasser… - Journal of the …, 2022 - lyellcollection.org
Glaciers respond sensitively to climate variability and change, with associated impacts on
meltwater production, sea-level rise and geomorphological hazards. There is a strong …

The state of rock debris covering Earth's glaciers

S Herreid, F Pellicciotti - Nature Geoscience, 2020 - nature.com
Rock debris can accumulate on glacier surfaces and dramatically reduce glacier melt. The
structure of a debris cover is unique to each glacier and sensitive to climate. Despite this …

Distributed global debris thickness estimates reveal debris significantly impacts glacier mass balance

DR Rounce, R Hock, RW McNabb… - Geophysical …, 2021 - Wiley Online Library
Supraglacial debris affects glacier mass balance as a thin layer enhances surface melting,
while a thick layer reduces it. While many glaciers are debris‐covered, global glacier models …

Medieval demise of a Himalayan giant summit induced by mega-landslide

J Lavé, C Guérin, PG Valla, V Guillou, T Rigaudier… - Nature, 2023 - nature.com
Despite numerous studies on Himalayan erosion, it is not known how the very high
Himalayan peaks erode. Although valley floors are efficiently eroded by glaciers, the …

Geomorphological evolution of a debris‐covered glacier surface

MJ Westoby, DR Rounce, TE Shaw… - Earth Surface …, 2020 - Wiley Online Library
There exists a need to advance our understanding of debris‐covered glacier surfaces over
relatively short timescales due to rapid, climatically induced areal expansion of debris cover …

Geometric form changes of soil quartz minerals under Freeze-thaw weathering

Q Liu, Z Zhang, J Zhai, S Zhang, K Zhou, A Melnikov… - Engineering …, 2023 - Elsevier
Freeze-thaw weathering can alter the geometry of soil minerals and severely damage the
Earth's surface. This has significant implications for the global geological environment. To …

Glaciers, rock avalanches and the 'buzzsaw'in cirque development: Why mountain cirques are of mainly glacial origin

IS Evans - Earth Surface Processes and Landforms, 2021 - Wiley Online Library
It has been proposed that most cirques are source‐area depressions of large, deep‐seated
rock‐slope failures. Yet the close relation between cirques and climate is convincing …

Supraglacial debris thickness and supply rate in High-Mountain Asia

M McCarthy, E Miles, M Kneib, P Buri… - … Earth & Environment, 2022 - nature.com
Supraglacial debris strongly modulates glacier melt rates and can be decisive for ice
dynamics and mountain hydrology. It is ubiquitous in High-Mountain Asia, yet because its …

Continuous borehole optical televiewing reveals variable englacial debris concentrations at Khumbu Glacier, Nepal

KE Miles, B Hubbard, ES Miles, DJ Quincey… - … Earth & Environment, 2021 - nature.com
Abstract Surface melting of High Mountain Asian debris-covered glaciers shapes the
seasonal water supply to millions of people. This melt is strongly influenced by the spatially …

Estimation of the total sub-debris ablation from point-scale ablation data on a debris-covered glacier

SS Shah, A Banerjee, HC Nainwal… - Journal of Glaciology, 2019 - cambridge.org
Glaciological ablation is computed from point-scale data at a few ablation stakes that are
usually regressed as a function of elevation and averaged over the area-elevation …
