Modelling climate sensitivity of debris-covered glaciers [PDF]
, 2022 The common occurrence of debris-covered glaciers in high-mountain areas makes their response to climate change relevant. The insulating effect of debris cover on surface melt causes debris-covered glaciers behave differently from debris-free glaciers, warranting the use of a specialized model for predictions.

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

A comparison of glacier melt on debris-covered glaciers in the northern and southern Caucasus [PDF]
The Cryosphere, 2011 Abstract. 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 many glaciers.

Volume-area scaling for debris-covered glaciers [PDF]
Journal of Glaciology, 2020 A volume-area scaling relation is commonly used to estimate glacier volume or its future changes on a global scale. The presence of an insulating supraglacial debris cover alters the mass-balance profile of a glacier, potentially modifying the scaling ...

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 ...

Reduced melt on debris-covered glaciers: investigations from Changri Nup Glacier, Nepal [PDF]
The Cryosphere, 2016 Approximately 25 % of the glacierized area in the Everest region is covered by debris, yet the surface mass balance of debris-covered portions of these glaciers has not been measured directly. In this study, ground-based measurements of surface elevation

Brief communication: Thinning of debris-covered and debris-free glaciers in a warming climate [PDF]
The Cryosphere, 2017 Recent geodetic mass-balance measurements reveal similar thinning rates on glaciers with or without debris cover in the Himalaya–Karakoram region. This comes as a surprise as a thick debris cover reduces the surface melting significantly due to its ...

Dynamics of debris-covered glaciers
, 2021 The presence of a supraglacial debris layer affects the melt of underlying ice which causes debris-covered glaciers to respond differently to climate forcing compared to clean-ice glaciers. To further complicate matters, supraglacial debris cover is not constant in time, but changes as a consequence of redistribution by ice flow, melt-out of englacial ...

Spatial Distribution and Characteristics of Debris-Covered Glaciers in Xinjiang Based on CGI-XJ2020
Remote SensingDebris cover is widespread on glaciers and strongly alters their surface albedo, energy balance, and ablation. Using the Chinese Glacier Inventory of Xinjiang 2020 (CGI-XJ2020), this study investigates the spatial distribution of debris-covered glaciers ...

Obliquity-paced climate change recorded in Antarctic debris-covered glaciers. [PDF]
Nat Commun, 2017 The degree to which debris-covered glaciers record past environmental conditions is debated. Here we describe a novel palaeoclimate archive derived from the surface morphology and internal debris within cold-based debris-covered glaciers in Antarctica ...
