Debris cover and the thinning of Kennicott Glacier, Alaska
2021<p>Many glaciers in High Mountain Asia are experiencing the debris-cover anomaly. The Kennicott Glacier, a large Alaskan Glacier, is also thinning most rapidly under debris cover. This contradiction has been explained by melt hotspots, such as ice cliffs, streams, or ponds scattered within the debris cover or by declining ice flow in time.

Modelling debris-covered glacier melt
2023Meltwater from glaciers contributes to hydro-electricity and agricultural production in some places, and model predictions of glacier melt can inform water management decisions. However, predictions are inherently uncertain. Accurately constrained uncertainty can be key to success of management decisions.

Debris thickness patterns on debris-covered glaciers
Geomorphology, 2018Abstract Many debris-covered glaciers have broadly similar debris thickness patterns: surface debris thickens and tends to transition from convex- to concave-up-down glacier. We explain this pattern using theory (analytical and numerical models) paired with empirical observations.

The geomorphology of debris-covered Ponkar Glacier, Nepal
2020<p>Understanding the evolution of debris-covered glaciers in High Mountain Asia is important for making informed projections of climate change impacts and associated water security and hazard-related issues. &#160;Here we describe the geomorphology of Ponkar Glacier, a debris-covered glacier in Nepal using high-resolution

<p>It is common for temperate glaciers in mountainous regions to exhibit an extensive ablation-zone supraglacial debris cover. Although secondary reworking of surface debris and its role in modifying rates of glacier melt is receiving increasing attention, debris origin and primary distribution is poorly understood. Arguably, studies have

DEBRIS-COVERED GLACIERS AND ROCK GLACIERS
2014The debris-covered glaciers are observed all over the glaciation regions of the world (Alps, Antarctica, Greenland, Ants, Cascades, Rocky Mountains and ext.). The debris covered glaciers are the formations which occur as a result of the recession of normal glaciers.

Inferring Debris Properties on Debris-Covered Glaciers: Implications for Glacier Modelling
Debris, ranging from thin surface dust to medial moraines and thick, continuous layers in ablation zones, partially covers glaciers all around the world. By modifying energy transfer from the atmosphere to the ice, the supraglacial debris layer fundamentally controls sub-debris melt rates.Vicente Melo Velasco +5 more
