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.

Impact of varying debris cover thickness on ablation: a case study for Koxkar Glacier in the Tien Shan [PDF]
The Cryosphere, 2014 To quantify the ablation processes on a debris covered glacier, a simple distributed ablation model has been developed and applied to a selected glacier. For this purpose, a set of field measurements was carried out to collect empirical data.

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.

High-resolution debris-cover mapping using UAV-derived thermal imagery: limits and opportunities [PDF]
The Cryosphere, 2023 Debris-covered glaciers are widespread in high mountain ranges on earth. However, the dynamic evolution of debris-covered glacier surfaces is not well understood, in part due to difficulties in mapping debris-cover thickness in high spatiotemporal ...

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 effect on the evolution of Northern Caucasus glaciers in the 21st century
Frontiers in Earth Science, 2023 More than 13% of the area of the Caucasus glaciers is covered by debris affecting glacier mass balance. Using the Caucasus as example, we introduce a new model configuration that incorporates a physically-based subroutine for the evolution of ...

Global Assessment of Supraglacial Debris‐Cover Extents [PDF]
Geophysical Research Letters, 2018 Rocky debris on glacier surfaces influences ice melt rates and the response of glaciers to climate change. However, scarce data on the extent and evolution of supraglacial debris cover have so far limited its inclusion in regional to global glacier ...

Unravelling the evolution of Zmuttgletscher and its debris cover since the end of the Little Ice Age [PDF]
The Cryosphere, 2019 Debris-covered glaciers generally exhibit large, gently sloping, slow-flowing tongues. At present, many of these glaciers show high thinning rates despite thick debris cover.

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 ...
