Distributed Melt on a Debris-Covered Glacier: Field Observations and Melt Modeling on the Lirung Glacier in the Himalaya [PDF]

Frontiers in Earth Science, 2021
Debris-covered glaciers, especially in high-mountain Asia, have received increased attention in recent years. So far, few field-based observations of distributed mass loss exist and both the properties of the debris layer as well as the atmospheric drivers of melt below debris remain poorly understood.

Aspect controls the survival of ice cliffs on debris-covered glaciers. [PDF]

Proc Natl Acad Sci U S A, 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 ...

Impact of debris cover on glacier ablation and atmosphere–glacier feedbacks in the Karakoram [PDF]

The Cryosphere, 2015
Abstract. The Karakoram range of the Hindu-Kush Himalaya is characterized by both extensive glaciation and a widespread prevalence of surficial debris cover on the glaciers. Surface debris exerts a strong control on glacier surface-energy and mass fluxes and, by modifying surface boundary conditions, has the potential to alter atmosphere–glacier ...

Thinning and surface mass balance patterns of two neighbouring debris-covered glaciers in the southeastern Tibetan Plateau [PDF]

The Cryosphere, 2023
Debris-covered glaciers are a common feature of the mountain cryosphere in the southeastern Tibetan Plateau. A better understanding of these glaciers is necessary to reduce the uncertainties in regional water resource variability and to anticipate ...

Novel Machine Learning Method Integrating Ensemble Learning and Deep Learning for Mapping Debris-Covered Glaciers

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.

Evolution of Surface Characteristics of Three Debris-Covered Glaciers in the Patagonian Andes From 1958 to 2020

Frontiers in Earth Science, 2021
A number of glaciological observations on debris-covered glaciers around the globe have shown a delayed length and mass adjustment in relation to climate variability, a behavior normally attributed to the ice insulation effect of thick debris layers ...

The Concept of Steady State, Cyclicity and Debris Unloading of Debris-Covered Glaciers

Frontiers in Earth Science, 2021
It can easily be expected that debris-covered glaciers show a different response on external forcing compared to clean-surface glaciers. The supra-glacial debris cover acts as an additional transfer layer for the energy exchange between atmosphere and ...

An energy-balance model for debris-covered glaciers including heat conduction through the debris layer [PDF]

, 2010
Extensive covers of supraglacial debris are often present in glacier ablation areas, and it is essential to assess exactly how the debris affects glacier melt rates.

The state of rock debris covering Earth’s glaciers [PDF]

Nature Geoscience, 2020
Rock debris can accumulate on glacier surfaces and dramatically reduce glacier melt. The structure of a debris cover is unique to each glacier and sensitive to climate. Despite this, debris cover has been omitted from global glacier models and forecasts of their response to a changing climate. Fundamental to resolving these omissions is a global map of

Patterns and drivers of glacier debris-cover development in the Afghanistan Hindu Kush Himalaya

Journal of Glaciology, 2023
Debris-covered ice is widespread in mountain regions with debris an important control on surface ice melt and glacier retreat. Quantifying debris cover extent and its evolution through time over large regions remains a challenge.
