The Biodiversity of Retreating Glaciers Leaves an Ecological Legacy in Emerging Soil Communities. [PDF]
Glob Chang BiolWe provide the first multi‐taxa assessment of biodiversity transitions across the supraglacial‐proglacial interface, using eDNA metabarcoding across five glacier systems. Recently deglaciated soils resemble supraglacial communities taxonomically and functionally, markedly for microbes and weakly for animals, with microbial similarity declining rapidly ...

Journal of Glaciology, 2021 Rock debris covers ~30% of glacier ablation areas in the Central Himalaya and modifies the impact of atmospheric conditions on mass balance. The thermal properties of supraglacial debris are diurnally variable but remain poorly constrained for monsoon ...

Understanding Complex Debris-Covered Glaciers: Concepts, Issues, and Research Directions
Frontiers in Earth Science, 2021 Understanding the climate-glacier dynamics of debris-covered glaciers is notoriously difficult given a multitude of controlling factors and feedback mechanisms involving climate forcing, debris-load properties, supraglacial water bodies, and multi-scale ...

Terrestrial Arthropod Responses to Arctic Cryosphere Degradation. [PDF]
Glob Chang BiolChanges in Arctic snow and ice are impacting terrestrial arthropods—for example, thinner snowpacks alter phenological synchrony and soil fauna survival; thawing permafrost increases decomposition, and glacial ice loss leads to the disappearance of adapted specialists; sea ice decline will have many indirect impacts for arthropods.

Modelling steady states and the transient response of debris-covered glaciers [PDF]
The Cryosphere, 2021 Debris-covered glaciers are commonly found in alpine landscapes of high relief and play an increasingly important role in a warming climate. As a result of the insulating effect of supraglacial debris, their response to changes in climate is less direct ...

Modelling debris transport within glaciers by advection in a full-Stokes ice flow model [PDF]
The Cryosphere, 2018 Glaciers with extensive surface debris cover respond differently to climate forcing than those without supraglacial debris. In order to include debris-covered glaciers in projections of glaciogenic runoff and sea level rise and to understand the ...

Remote Sensing, 2022 High-mountain glaciers can be covered with varying degrees of debris. Debris over glaciers (supraglacial debris) significantly alter glacier melt, velocity, ice geometry, and, thus, the overall response of glaciers towards climate change. The accumulated

Controls on the relative melt rates of debris-covered glacier surfaces
Environmental Research Letters, 2022 Supraglacial debris covers 7% of mountain glacier area globally and generally reduces glacier surface melt. Enhanced energy absorption at ice cliffs and supraglacial ponds scattered across the debris surface leads these features to contribute ...

Sub-seasonal variability of supraglacial ice cliff melt rates and associated processes from time-lapse photogrammetry [PDF]
The Cryosphere, 2022 Melt from supraglacial ice cliffs is an important contributor to the mass loss of debris-covered glaciers. However, ice cliff contribution is difficult to quantify as they are highly dynamic features, and the paucity of observations of melt rates and ...

Journal of Glaciology, 2023 Supraglacial debris cover regulates the melt rates of many glaciers in mountainous regions around the world, thereby modifying the availability and quality of downstream water resources.
