The cryosphere plays an important role in the global carbon cycle, but few studies have examined carbon fluxes specifically on debris-covered glaciers.

Stream hydrology controls on ice cliff evolution and survival on debris-covered glaciers [PDF]
Ice cliffs are melt hot spots that contribute disproportionately to melt on debris-covered glaciers. In this study, we investigate the impact of supraglacial stream hydrology on ice cliffs using in situ and remote sensing observations, streamflow ...

Modelling the evolution of Djankuat Glacier, North Caucasus, from 1752 until 2100 CE [PDF]
We use a numerical flow line model to simulate the behaviour of the Djankuat Glacier, a World Glacier Monitoring Service reference glacier situated in the North Caucasus (Republic of Kabardino-Balkaria, Russian Federation), in response to past, present ...

Automated detection of ice cliffs within supraglacial debris cover [PDF]
Abstract. Ice cliffs within a supraglacial debris cover have been identified as a source for high ablation relative to the surrounding debris-covered area. Due to their small relative size and steep orientation, ice cliffs are difficult to detect using nadir-looking space borne sensors.

Climate Warming and Ice Weakening Trigger Alpine Glacier Collapses: The Marmolada Case
Abstract The rapid retreat of temperate mid‐latitude glaciers due to global warming causes dramatic mass loss and increases their instability. Using a synthesis of thermodynamic and mechanical laws, we constructed a three‐dimensional stability model and applied it in the analysis of the collapse of a portion of the Marmolada Glacier in northeastern ...

Sub-debris melt rates on southern Inylchek Glacier, central Tian Shan [PDF]
Melt rates of glacier surfaces are strongly influenced by the existence of a debris cover. Dependent on thickness and other physical parameters the debris layer can enhance or reduce ablation as compared to bare ice conditions.

A large number of glaciers in the Hindu-Kush Himalaya are covered with debris in the lower part of the ablation zone, which is continuously expanding due to enhanced glacier mass loss.

Modelling and constraining supraglacial discharge, channel incision and ice cliff backwasting on a debris-covered glacier [PDF]
Understanding the behaviour of debris-covered glaciers is essential for estimating their mass balances. As opposed to the expected insulating factor of debris, recent studies have observed debris-covered glaciers to have similar melt rates as clean ice ...

Supraglacial pools are prevalent on debris-covered mountain glaciers, yet only limited information is available on the microbial communities within these habitats.

Supraglacial ponds and ice cliffs can dramatically enhance ablation rates on debris-covered glaciers. Supraglacial ponds can also coalesce, forming moraine-dammed lakes at risk of glacial lake outburst flood (GLOF).
