Field-based research directions for investigating the interior of high-elevation debris-covered glaciers [PDF]
Annals of Glaciology, 2022 The debris that covers the ablation areas of high-elevation debris-covered glaciers contributes to the distinctive features and processes occurring both on and within such glaciers.

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.

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

Southwest-facing slopes control the formation of debris-covered glaciers in the Bhutan Himalaya [PDF]
The Cryosphere, 2013 To understand the formation conditions of debris-covered glaciers, we examined the dimension and shape of debris-covered areas and potential debris-supply (PDS) slopes of 213 glaciers in the Bhutan Himalaya.

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.

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 ...

Modelling the dynamics and evolution of debris-covered glaciers [PDF]
, 2022 Debris-covered glaciers are found in most of the world’s glacierized areas. The presence of debris on the glacier surface affects the ablation rate of the underlying ice. When the debris cover exceeds a thickness of a few centimetres, thermal insulation becomes dominant, thereby reducing the ablation of the underlying ice so that for a given climate ...

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 ...

Frontiers in Earth Science, 2021 Ongoing changes in mountain glaciers affect local water resources, hazard potential and global sea level. An increasing proportion of remaining mountain glaciers are affected by the presence of a surface cover of rock debris, and the response of these ...
