Including debris cover effects in a distributed model of glacier ablation
, 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.

Remote Sensing, 2021 Glaciers in High Mountain Asia (HMA) have a significant impact on human activity. Thus, a detailed and up-to-date inventory of glaciers is crucial, along with monitoring them regularly.

International Workshop Examines Debris‐covered Glaciers
Eos, Transactions American Geophysical Union, 2001 Glaciers are important features in climate studies. The smaller alpine glaciers respond to climatic variation in ways visible during the human lifetime. Glacial processes modify the landscape leaving signatures of past climatic conditions. The large ice sheets have an important role in the global heat and water balance, which in turn play a major role ...

Ablation process of debris-covered glaciers.
Journal of the Japanese Society of Snow and Ice, 2001 岩屑に覆われた永河の融解過程は複雑で観測が困難なためこれまで詳細な研究が少なかった.当初の研究は岩屑に覆われた部分に重点がおかれ,均一な厚さの岩屑に覆われた氷雪の融解についての実験的研究が多くの研究者によって行われてきた.実際の氷河では岩屑の粒径,組成,厚さなどの分布を広い面にわたって把握することが困難であった.そこで近年発達した衛星画像で得られた表面温度分布から消耗域全体の融解量を推定するモデルが開発された.このモデルにより推定された値は実際の岩屑に覆われた氷河の融解量よりも大きくなった.この原因は岩屑氷河の池や氷壁の部分で大きな熱の吸収が氷河の融解を促進させていることが一因と考えられる.

The role of differential ablation and dynamic detachment in driving accelerating mass loss from a debris‐covered Himalayan glacier [PDF]
, 2021 Sustained mass loss from Himalayan glaciers is causing supraglacial debris to expand and thicken, with the expectation that thicker debris will suppress ablation and extend glacier longevity.

Aspect controls the survival of ice cliffs on debris-covered glaciers [PDF]
Proceedings of the National Academy of Sciences, 2018 Significance Glaciers in High Mountain Asia (HMA) are important water sources for millions of people downstream. Ice cliffs on debris-covered glaciers act as hot spots for melt and may explain anomalously high glacier mass losses in HMA, but their temporal evolution remains unknown, hindering sound parameterizations of these features in ...
