CARBON GAS CYCLING IN SUPRAGLACIAL DEBRIS COVERS
Geological Society of America Abstracts with Programs, 2020<p>Debris-covered glaciers extend over 4000 km2 in the high Asian Mountains and are significant and expanding features of most of the World&#8217;s glacierized mountain ranges. Within supraglacial debris covers, a combination of fresh mechanically-weathered rock and an abundance of water and energy during melt seasons ...

Temporal variations in supraglacial debris distribution on Baltoro Glacier, Karakoram between 2001 and 2012 [PDF]
Geomorphology, 2017 Distribution of supraglacial debris in a glacier system varies spatially and temporally due to differing rates of debris input, transport and deposition.

Characterizing the role of supraglacial debris thickness variability on underlyingice ablation
2022<p>Projections of future climate implicate the thickening of debris-covered glaciers. Thus it becomes<br>increasingly important to consider the influences of the debris layer on glacier melt especially<br>because of the strong non-linear relationship between debris thickness and ablation rate.

Properties of natural supraglacial debris in relation to modelling sub‐debris ice ablation
Earth Surface Processes and Landforms, 2012ABSTRACTAs debris‐covered glaciers become a more prominent feature of a shrinking mountain cryosphere, there is increasing need to successfully model the surface energy and mass balance of debris‐covered glaciers, yet measurements of the processes operating in natural supraglacial debris covers are sparse. We report measurements of vertical temperature

Probing supraglacial debris on Mars 2: Crater morphology
Icarus, 2019Abstract Lobate debris aprons (LDA), lineated valley fill (LVF), and concentric crater fill (CCF) on Mars, interpreted to be debris-covered glaciers, possess craters with a suite of distinct interior landforms (called “ring-mold craters”) that have been attributed to the presence of glacial ice at depth or surface modification processes.

<p>It is common for temperate glaciers in mountainous regions to exhibit an extensive ablation-zone supraglacial debris cover. Although secondary reworking of surface debris and its role in modifying rates of glacier melt is receiving increasing attention, debris origin and primary distribution is poorly understood. Arguably, studies have

DebDab: A database of physical properties of supraglacial debris
Rocky debris layers cover an increasing portion of glacier ablation areas as glaciers thin and retreat in response to climate change, progressively altering surface melt rates. However, determining the thickness and physical properties of supraglacial debris that are required for accurate representation of debris in glacier melt models is challenging ...Adrià Fontrodona-Bach +6 more

Recognition of supraglacial debris in the Tianshan Mountains on polarimetric SAR images
Remote Sensing of Environment, 2014Abstract Debris cover is widely present in the ablation areas of mountain glaciers. Such debris plays an important role in glacier mass balance, but it complicates the glacier boundary and area estimation when using remotely sensed images. Automatic recognition of the debris is much more difficult than recognizing bare ice on optical remotely sensed ...

The role of supraglacial debris in Himalaya-Karakoram debris-covered glacier systems
2017Spatiotemporal variability in supraglacial debris properties have the potential to affect estimations of mass balance for debris-covered glaciers. This thesis is concerned with identifying the extent to which debris properties vary in space and time, and the role of these variabilities in estimations of specific mass balance.
