Determinants of microbial community structure in supraglacial pool sediments of monsoonal Tibetan Plateau [PDF]
Microbiology SpectrumSupraglacial pools are prevalent on debris-covered mountain glaciers, yet only limited information is available on the microbial communities within these habitats.

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 ...

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.

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.

Supraglacial debris thickness and supply rate in High-Mountain Asia
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.

Pond Dynamics and Supraglacial-Englacial Connectivity on Debris-Covered Lirung Glacier, Nepal [PDF]
Frontiers in Earth Science, 2017 The hydrological systems of heavily-downwasted debris-covered glaciers differ from those of clean-ice glaciers due to the hummocky surface and debris mantle of such glaciers, leading to a relatively limited understanding of drainage pathways ...

Surface composition of debris-covered glaciers across the Himalaya using linear spectral unmixing of Landsat 8 OLI imagery [PDF]
The Cryosphere, 2021 The Himalaya mountain range is characterized by highly glacierized, complex, dynamic topography. The ablation area of Himalayan glaciers often features a highly heterogeneous debris mantle comprising ponds, steep and shallow slopes of various aspects ...

Detecting supraglacial debris thickness with GPR under suboptimal conditions [PDF]
Journal of Glaciology, 2021 The thickness of a supraglacial layer is critical to the magnitude and time frame of glacier melt. Field-based, short pulse, ground-penetrating radar (GPR) has successfully measured debris thickness during a glacier's melt season, when there is a strong return from the ice–debris interface, but profiling with GPR in the absence of a highly reflective ...

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
