Quantifying supraglacial debris thickness at local to regional scales
Supraglacial debris thickness is a key control on the surface energy balance of debris-covered glaciers, which are common in temperate mountain ranges around the world. As such, it is an important input variable to the sorts of models that are used to understand and predict glacier change, which …

Quantifying Supraglacial Debris Thickness and the Glaciological Controls on its Spatial Distribution in High Mountain Asia
As debris-covered glaciers (DCGs) become a more prominent feature of the shrinking mountain cryosphere (Shukla et al., 2009; Thakuri et al., 2014; Gaddam et al. 2016; Tielidze et al., 2019), there is an increasing need to understand how they will respond to climate change. In particular, there is a …

Glacier Monitoring in Ladakh and Zanskar, northwestern India
… in the Himalaya are often heavily covered with supraglacial debris, making them difficult to study with remotely-sensed imagery alone. Various methods such as band ratios can be used effectively to map clean-ice glaciers; however, a thicker layer of debris often makes it impossible to …

The role of cold supraglacial volcanic deposits in influencing glacial ablation
… factor in glacial ablation is the influence of supraglacial debris deposits, which can have both positive and negative effects. A critical thickness exists at which sub-debris ablation is equal to that of bare ice; debris will hinder ablation if it exceeds this thickness, and enhance it if its …

Utilisation of remote sensing for the study of debris-covered glaciers: development and testing of techniques on Miage Glacier, Italian Alps
An increase in the number of debris-covered glaciers and expansion of debris cover across many glaciers has been documented in many of the world’s major glacierised mountain ranges over the last 100 years. Debris cover has a profound impact on glacier mass balance with thick layers insulating the …
