Numerical Simulation of Supraglacial Debris Mobility: Implications for Ablation and Landform Genesis

Frontiers in Earth Science, 2021
Supraglacial debris does not remain fixed atop ablating ice, but can move across the ice surface as supraglacial topography evolves. This active debris movement (distinct from passive movement due to underlying ice motion) affects landform genesis as ...

DERIVATION OF SUPRAGLACIAL DEBRIS COVER BY MACHINE LEARNING ALGORITHMS ON THE GEE PLATFORM: A CASE STUDY OF GLACIERS IN THE HUNZA VALLEY [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
Calculating the spatial-temporal distribution of supraglacial debris cover on glaciers is essential for understanding mass balance processes, glacier lake outburst floods, hydrological predictions, and glacier fluctuations that have attracted attention ...

Influence of Supraglacial Debris Thickness on Thermal Resistance of the Glaciers of Chandra Basin, Western Himalaya

Frontiers in Earth Science, 2021
A large number of glaciers in the Hindu-Kush Himalaya are covered with debris in the lower part of the ablation zone, which is continuously expanding due to enhanced glacier mass loss.

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

Geochemical characterization of supraglacial debris via in situ and optical remote sensing methods: a case study in Khumbu Himalaya, Nepal [PDF]

The Cryosphere, 2012
Surface glacier debris samples and field spectra were collected from the ablation zones of Nepal Himalaya Ngozumpa and Khumbu glaciers in November and December 2009.

Seasonally stable temperature gradients through supraglacial debris in the Everest region of Nepal, Central Himalaya

Journal of Glaciology, 2021
Rock debris covers ~30% of glacier ablation areas in the Central Himalaya and modifies the impact of atmospheric conditions on mass balance. The thermal properties of supraglacial debris are diurnally variable but remain poorly constrained for monsoon ...

Supraglacial Ponds Regulate Runoff From Himalayan Debris‐Covered Glaciers [PDF]

Geophysical Research Letters, 2017
AbstractMeltwater and runoff from glaciers in High Mountain Asia is a vital freshwater resource for one‐fifth of the Earth's population. Between 13% and 36% of the region's glacierized areas exhibit surface debris cover and associated supraglacial ponds whose hydrological buffering roles remain unconstrained.

Understanding Complex Debris-Covered Glaciers: Concepts, Issues, and Research Directions

Frontiers in Earth Science, 2021
Understanding the climate-glacier dynamics of debris-covered glaciers is notoriously difficult given a multitude of controlling factors and feedback mechanisms involving climate forcing, debris-load properties, supraglacial water bodies, and multi-scale ...

Modelling steady states and the transient response of debris-covered glaciers [PDF]

The Cryosphere, 2021
Debris-covered glaciers are commonly found in alpine landscapes of high relief and play an increasingly important role in a warming climate. As a result of the insulating effect of supraglacial debris, their response to changes in climate is less direct ...

Modelling debris transport within glaciers by advection in a full-Stokes ice flow model [PDF]

The Cryosphere, 2018
Glaciers with extensive surface debris cover respond differently to climate forcing than those without supraglacial debris. In order to include debris-covered glaciers in projections of glaciogenic runoff and sea level rise and to understand the ...
