Modeling debris-covered glaciers: response to steady debris deposition [PDF]
The Cryosphere, 2016 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 present, ablation rates can be significantly reduced leading to increases in

Global Assessment of Supraglacial Debris‐Cover Extents [PDF]
Geophysical Research Letters, 2018 AbstractRocky debris on glacier surfaces influences ice melt rates and the response of glaciers to climate change. However, scarce data on the extent and evolution of supraglacial debris cover have so far limited its inclusion in regional to global glacier models. Here we present global data sets of supraglacial debris‐cover extents, based on Landsat 8

Upward Expansion of Supra-Glacial Debris Cover in the Hunza Valley, Karakoram, During 1990 ∼ 2019
Frontiers in Earth Science, 2020 Supra-glacial debris cover is key to glacier ablation through increasing (thin debris layer) or decreasing (thick debris layer) melt rates, thereby regulating the mass balance of a glacier and its meltwater runoff.

Processes at the margins of supraglacial debris cover: Quantifying dirty ice ablation and debris redistribution [PDF]
Earth Surface Processes and Landforms, 2020 AbstractCurrent 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 ablation compared to clean ice, but often this cover is patchy rather than continuous. There is a need to understand ablation and debris dynamics in this transition

Impact of varying debris cover thickness on ablation: a case study for Koxkar Glacier in the Tien Shan [PDF]
The Cryosphere, 2014 To quantify the ablation processes on a debris covered glacier, a simple distributed ablation model has been developed and applied to a selected glacier. For this purpose, a set of field measurements was carried out to collect empirical data.

Brief communication: Thinning of debris-covered and debris-free glaciers in a warming climate [PDF]
The Cryosphere, 2017 Recent geodetic mass-balance measurements reveal similar thinning rates on glaciers with or without debris cover in the Himalaya–Karakoram region. This comes as a surprise as a thick debris cover reduces the surface melting significantly due to its ...

The Concept of Steady State, Cyclicity and Debris Unloading of Debris-Covered Glaciers [PDF]
Frontiers in Earth Science, 2021 It can easily be expected that debris-covered glaciers show a different response on external forcing compared to clean-surface glaciers. The supra-glacial debris cover acts as an additional transfer layer for the energy exchange between atmosphere and ...

Debris cover effect on the evolution of Northern Caucasus glaciers in the 21st century
Frontiers in Earth Science, 2023 More than 13% of the area of the Caucasus glaciers is covered by debris affecting glacier mass balance. Using the Caucasus as example, we introduce a new model configuration that incorporates a physically-based subroutine for the evolution of ...

Large-Scale Debris Cover Glacier Mapping Using Multisource Object-Based Image Analysis Approach
Remote Sensing, 2022 Large-scale debris cover glacier mapping can be efficiently conducted from high spatial resolution (HSR) remote sensing imagery using object-based image analysis (OBIA), which works on a group of pixels.
