A comparison of glacier melt on debris-covered glaciers in the northern and southern Caucasus [PDF]
The Cryosphere, 2011 The glacier coverage in the Caucasus Mountains underwent considerable changes during the last decades. In some regions, the observed reduction in glacier area is comparable to those in the European Alps and the extent of supra-glacial debris increased on

Modeling debris-covered glaciers: response to steady debris deposition [PDF]
The Cryosphere, 2016 Debris-covered glaciers are common in rapidly eroding alpine landscapes. When thicker than a few centimeters, surface debris suppresses melt rates. If continuous debris cover is present, ablation rates can be significantly reduced leading to increases in

Debris cover effects on energy and mass balance of Batura Glacier in the Karakoram over the past 20 years [PDF]
Hydrology and Earth System SciencesThe influence of supraglacial debris cover on glacier mass balance in the Karakoram is noteworthy. However, understanding of how debris cover affects the seasonal and long-term variations in glacier mass balance through alterations in the glacier's ...

Debris Cover Limits Subglacial Erosion and Promotes Till Accumulation. [PDF]
Geophys Res Lett, 2022 Glaciers are commonly conceptualized as bodies composed of snow and ice. Yet, many glaciers contain a substantial amount of rock, especially those abutting steep mountains. Mountain slopes erode, depositing rocks on glaciers below.

Modelling steady states and the transient response of debris-covered glaciers [PDF]
The Cryosphere, 2021 Debris-covered glaciers are commonly found in alpine landscapes of high relief and play an increasingly important role in a warming climate. As a result of the insulating effect of supraglacial debris, their response to changes in climate is less direct ...

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 ...

Landscape Evolution in Glacier Valleys of Glaciokarsts
Geosciences, 2023 The landscape evolution of the glacier valleys of glaciokarsts is described. Depending on the character of coveredness (quality and thickness of the cover), altitude and the presence of karst features, different ways of geomorphic evolution occur ...

Atmospheric Science Letters, 2021 Many of the glaciers in the Nepalese Himalaya are partially covered in a layer of loose rock known as debris cover. In the Dudh Koshi River Basin, Nepal, approximately 25% of glaciers are debris‐covered.

Supra-glacial debris cover changes in the Greater Caucasus from 1986 to 2014 [PDF]
The Cryosphere, 2020 Knowledge of supra-glacial debris cover and its changes remain incomplete in the Greater Caucasus, in spite of recent glacier studies. Here we present data of supra-glacial debris cover for 659 glaciers across the Greater Caucasus based on Landsat and ...

Mapping Surface Features of an Alpine Glacier through Multispectral and Thermal Drone Surveys
Remote Sensing, 2023 Glacier surfaces are highly heterogeneous mixtures of ice, snow, light-absorbing impurities and debris material. The spatial and temporal variability of these components affects ice surface characteristics and strongly influences glacier energy and mass ...
