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 …

Modeling debris-covered glaciers: response to steady debris deposition

LS Anderson, RS Anderson - The Cryosphere, 2016 - tc.copernicus.org
Debris-covered glaciers are common in rapidly eroding alpine landscapes. When thicker
than a few centimeters, surface debris suppresses melt rates. If continuous debris cover is …

Glacier retreat and tourism: Insights from New Zealand

H Purdie - Mountain Research and Development, 2013 - BioOne
Glacier tourism, a multimillion-dollar industry in New Zealand, is potentially under threat by
ongoing glacial retreat. Surface morphology changes associated with retreat and thinning …

Processes at the margins of supraglacial debris cover: Quantifying dirty ice ablation and debris redistribution

CL Fyffe, AS Woodget, MP Kirkbride… - Earth Surface …, 2020 - Wiley Online Library
Current glacier ablation models have difficulty simulating the high‐melt transition zone
between clean and debris‐covered ice. In this zone, thin debris cover is thought to increase …

[HTML][HTML] Thin debris layers do not enhance melting of the Karakoram glaciers

S Muhammad, L Tian, S Ali, Y Latif, MA Wazir… - Science of the Total …, 2020 - Elsevier
The assessment of meltwater sourcing from the clean and debris-covered glaciers is scarce
in High Mountain Asia (HMA). The melting rate varies with the debris cover thickness and …

Evidence for slow late-glacial ice retreat in the upper Rangitata Valley, South Island, New Zealand

J Shulmeister, D Fink, S Winkler, GD Thackray… - Quaternary Science …, 2018 - Elsevier
A suite of cosmogenic radionuclide ages taken from boulders on lateral and latero-terminal
moraines in the Rangitata Valley, eastern South Island, New Zealand demonstrates that …

Debris-covered glaciers

E Mayr, W Hagg - Geomorphology of Proglacial Systems: Landform and …, 2019 - Springer
Debris-covered glaciers are characterised by a mantle of rock material, the supraglacial
debris, spread over part of the ablation zone. The debris material origins from the catchment …

Evolution of the sparse debris cover during the ablation season at two small Alpine glaciers (Gran Zebrù and Sforzellina, Ortles-Cevedale group)

G Tarca, M Guglielmin - Geomorphology, 2022 - Elsevier
Despite the increase of sparse debris on many glaciers in the world and its undisputed
impact on glacier ablation, both its evolution and its detailed effect have been poorly …

Quantifying supraglacial debris‐related melt‐altering effects on the Djankuat Glacier, Caucasus, Russian Federation

Y Verhaegen, O Rybak, VV Popovnin… - Journal of …, 2024 - Wiley Online Library
We use a spatially distributed and physically based energy and mass balance model to
derive the Østrem curve, which expresses the supraglacial debris‐related relative melt …
