Modelling supraglacial debris-cover evolution from the single-glacier to the regional scale: an application to High Mountain Asia [PDF]

The Cryosphere, 2022
Currently, about 12 %–13 % of High Mountain Asia’s glacier area is debris-covered, which alters its surface mass balance. However, in regional-scale modelling approaches, debris-covered glaciers are typically treated as clean-ice glaciers, leading to a ...

Including debris cover effects in a distributed model of glacier ablation [PDF]

, 2012
Distributed glacier melt models generally assume that the glacier surface consists of bare exposed ice and snow. In reality, many glaciers are wholly or partially covered in layers of debris that tend to suppress ablation rates.

Downwasting and supraglacial lake evolution on the debris-covered Ngozumpa Glacier, Khumbu Himal, Nepal [PDF]

, 2015
In recent decades, the downwasting of several debris-covered glaciers in the Himalaya has led to the formation of large and potentially hazardous moraine- dammed lakes.

Remotely sensed debris thickness mapping of Bara Shigri Glacier, Indian Himalaya [PDF]

, 2015
Despite the important role of supraglacial debris in ablation, knowledge of debris thickness on Himalayan glaciers is sparse. A recently developed method based on reanalysis data and thermal band satellite imagery has proved to be potentially suitable ...

Discriminating viscous-creep features (rock glaciers) in mountain permafrost from debris-covered glaciers – a commented test at the Gruben and Yerba Loca sites, Swiss Alps and Chilean Andes [PDF]

The Cryosphere
Viscous-flow features in perennially frozen talus/debris called rock glaciers are being systematically inventoried as part of the global climate-related monitoring of mountain permafrost.

Supraglacial Ice Cliffs Can Substantially Increase the Mass Loss of Debris‐Covered Glaciers

Geophysical Research Letters, 2021
The thinning patterns of debris‐covered glaciers in High Mountain Asia are not well understood. Here we calculate the effect of supraglacial ice cliffs on the mass balance of all glaciers in a Himalayan catchment, using a process‐based ice cliff melt ...

Glacier branch lines and glacier ice thickness estimation for debris-covered glaciers in the Central Tien Shan

Journal of Glaciology, 2018
Information about the ice volume stored in glaciers is of high importance for sustainable water management in many arid regions of Central Asia. Several methods to estimate the ice volume exist.

Air temperature distribution and energy balance modelling of a debris-covered glacier [PDF]

, 2016
Near-surface air temperature is an important determinant of the surface energy balance of glaciers that is often represented by constant linear temperature gradients in models.

DebDaB: a database of supraglacial debris thickness and physical properties [PDF]

Earth System Science Data
Rocky debris covers around 7.3 % of the global glacier area, influencing ice melt rates and the surface mass balance of glaciers, making the dynamics and hydrology of debris-covered glaciers distinct from those of clean-ice glaciers.

Using ArcticDEM to Analyse the Dimensions and Dynamics of Debris-Covered Glaciers in Kamchatka, Russia

Geosciences, 2018
On the Kamchatka Peninsula, a number of glaciers are covered by thick volcanic debris, which makes their margins difficult to delineate from satellite imagery. Fortunately, high resolution, multi-temporal digital surface models (DSMs) covering the entire
