Estimation of Supraglacial Dust and Debris Geochemical Composition via Satellite Reflectance and Emissivity [PDF]
Remote Sensing, 2012 We demonstrate spectral estimation of supraglacial dust, debris, ash and tephra geochemical composition from glaciers and ice fields in Iceland, Nepal, New Zealand and Switzerland.

DebDaB: a database of supraglacial debris thickness and physical properties [PDF]
Earth System Science DataRocky 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.

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

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.

Supraglacial debris thickness and supply rate in High-Mountain Asia [PDF]
Communications Earth & Environment, 2022 Supraglacial debris in High-Mountain Asia is extensively thin and its supply rate from local topography increases with the temperature and slope of debris-supply slopes, according to analyses of remote sensing data from over 4600 glaciers.

Influence of Supraglacial Debris Thickness on Thermal Resistance of the Glaciers of Chandra Basin, Western Himalaya [PDF]
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.

GERALDINE (Google Earth Engine supRaglAciaL Debris INput dEtector): a new tool for identifying and monitoring supraglacial landslide inputs [PDF]
Earth Surface Dynamics, 2020 Landslides in glacial environments are high-magnitude, long-runout events, believed to be increasing in frequency as a paraglacial response to ice retreat and thinning and, arguably, due to warming temperatures and degrading permafrost above current ...

Supraglacial debris thickness variability: impact on ablation and relation to terrain properties [PDF]
The Cryosphere, 2018 Shallow ground-penetrating radar (GPR) surveys are used to characterize the small-scale spatial variability of supraglacial debris thickness on a Himalayan glacier. Debris thickness varies widely over short spatial scales.

Morphology and evolution of supraglacial hummocks on debris‐covered Himalayan glaciers [PDF]
Earth Surface Processes and Landforms, 2021 AbstractThick supraglacial debris layers often have an undulating, hummocky topography that influences the lateral transport of debris and meltwater and provides basins for supraglacial ponds. The role of ablation and other processes associated with supraglacial debris in giving rise to this hummocky topography is poorly understood.
