CARBON GAS CYCLING IN SUPRAGLACIAL DEBRIS COVERS

Geological Society of America Abstracts with Programs, 2020
<p>Debris-covered glaciers extend over 4000 km2 in the high Asian Mountains and are significant and expanding features of most of the World’s glacierized mountain ranges. Within supraglacial debris covers, a combination of fresh mechanically-weathered rock and an abundance of water and energy during melt seasons ...

Debris thickness patterns on debris-covered glaciers

Geomorphology, 2018
Abstract 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.

Structurally controlled englacial origin of supraglacial debris cover and relief at a debris-covered Alpine glacier

2022
<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

2018
Debris-covered glaciers are characterised by a mantle of rock material, the supraglacial debris, spread over part of the ablation zone. The debris material origins from the catchment above and the bedrock below the glacier and appears at the glacier surface in the ablation zone.

Evolution and hydrological importance of debris-covered glaciers and ice-debris landforms

2021
<p>Debris-covered glaciers and ice-debris landforms such as rock glaciers are common in many mountain areas of Earth, are important for the debris transport system and contain a significant amount of ice. The presence, amount and characteristics of debris can strongly alter ice melt and the evolution of glaciers and ice-debris landforms ...

Evolution of the debris-covered Miage Glacier

2021
<p>Glaciers in high-mountain regions typically exhibit a debris cover that moderates their response to climatic change. Here we present an integrated study that integrates long-term observations of debris-covered glacier mass balance, velocity, surface debris evolution and geomorphological changes (such as ponds and ice cliffs) of Miage ...
