Sub-debris melt rates on southern Inylchek Glacier, central Tian Shan [PDF]

, 2008
Melt rates of glacier surfaces are strongly influenced by the existence of a debris cover. Dependent on thickness and other physical parameters the debris layer can enhance or reduce ablation as compared to bare ice conditions.

Understanding Complex Debris-Covered Glaciers: Concepts, Issues, and Research Directions

Frontiers in Earth Science, 2021
Understanding the climate-glacier dynamics of debris-covered glaciers is notoriously difficult given a multitude of controlling factors and feedback mechanisms involving climate forcing, debris-load properties, supraglacial water bodies, and multi-scale ...

Influence of Supraglacial Debris Thickness on Thermal Resistance of the Glaciers of Chandra Basin, Western Himalaya

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.

Controls on Ice Cliff Distribution and Characteristics on Debris‐Covered Glaciers

Geophysical Research Letters, 2023
Ice cliff distribution plays a major role in determining the melt of debris‐covered glaciers but its controls are largely unknown. We assembled a data set of 37,537 ice cliffs and determined their characteristics across 86 debris‐covered glaciers within ...

Using climate reanalysis data in conjunction with multi-temporal satellite thermal imagery to derive supraglacial debris thickness changes from energy-balance modelling

Journal of Glaciology, 2021
Surface energy-balance models are commonly used in conjunction with satellite thermal imagery to estimate supraglacial debris thickness. Removing the need for local meteorological data in the debris thickness estimation workflow could improve the ...

Debris thickness of glaciers in the Everest area (Nepal Himalaya) derived from satellite imagery using a nonlinear energy balance model [PDF]

The Cryosphere, 2014
Debris thickness is an important characteristic of debris-covered glaciers in the Everest region of the Himalayas. The debris thickness controls the melt rates of the glaciers, which has large implications for hydrologic models, the glaciers' response to

Rapid sequestration of rock avalanche deposits within glaciers [PDF]

, 2015
Topographic development in mountainous landscapes is a complex interplay between tectonics, climate and denudation. Glaciers erode valleys to generate headwall relief, and hillslope processes control the height and retreat of the peaks.

Internal structure and water routing of an ice-debris landform assemblage using multiple geophysical methods in the semiarid Andes

Frontiers in Earth Science, 2023
Rock glaciers are the most abundant (peri) glacial landform in the semiarid Andes (SA, 29–34°S), covering about three times the area of mountain glaciers.

Satellite and UAV remote sensing of debris-covered glaciers [PDF]

, 2022
Mountain glaciers play a crucial role in the global provision of water resources. The majority of these glaciers are retreating rapidly in response to anthropogenic climate change, posing serious risks to downstream communities, many of which are located
