Modelling runoff from a Himalayan debris-covered glacier [PDF]

Hydrology and Earth System Sciences, 2014
Abstract. Although the processes by which glacial debris mantles alter the melting of glacier ice have been well studied, the mass balance and runoff patterns of Himalayan debris-covered glaciers and the response of these factors to climate change are not well understood.

Controls on Ice Cliff Distribution and Characteristics on Debris‐Covered Glaciers

Geophysical Research Letters, 2023
AbstractIce cliff distribution plays a major role in determining the melt of debris‐covered glaciers but its controls are largely unknown. We assembled a data set of 37,537 ice cliffs and determined their characteristics across 86 debris‐covered glaciers within High Mountain Asia (HMA). We find that 38.9% of the cliffs are stream‐influenced, 19.5% pond‐

Obliquity-paced climate change recorded in Antarctic debris-covered glaciers [PDF]

Nature Communications, 2017
AbstractThe degree to which debris-covered glaciers record past environmental conditions is debated. Here we describe a novel palaeoclimate archive derived from the surface morphology and internal debris within cold-based debris-covered glaciers in Antarctica. Results show that subtle changes in mass balance impart major changes in the concentration of

Debris‐covered glaciers and rock glaciers in the nanga parbat himalaya, pakistan [PDF]

Geografiska Annaler: Series A, Physical Geography, 2000
The origin and mobilization of the extensive debris cover associated with the glaciers of the Nanga Parbat Himalaya is complex. In this paper we propose a mechanism by which glaciers can form rock glaciers through inefficiency of sediment transfer from glacier ice to meltwater.

Hydrology of debris-covered glaciers in High Mountain Asia [PDF]

Earth-Science Reviews, 2020
The hydrological characteristics of debris-covered glaciers are known to be fundamentally different from those of clean-ice glaciers, even within the same climatological, geological, and geomorphological setting. Understanding how these characteristics influence the timing and magnitude of meltwater discharge is particularly important for regions where

Sediment supply from lateral moraines to a debris-covered glacier in the Himalaya

Earth Surface Dynamics, 2019
. Debris-covered glaciers in the Himalaya play an important role in the high-altitude water cycle. The thickness of the debris layer is a key control of the melt rate of those glaciers, yet little is known about the relative importance of the three ...

Meteorological impacts of a novel debris‐covered glacier category in a regional climate model across a Himalayan catchment

Atmospheric Science Letters, 2020
Many of the glaciers in the Nepalese Himalaya are partially covered in a layer of loose rock known as debris cover. In the Dudh Koshi River Basin, Nepal, approximately 25% of glaciers are debris‐covered.

Do debris-covered glaciers demonstrate distinctive hydrological behaviour compared to clean glaciers? [PDF]

Journal of Hydrology, 2019
Supraglacial debris is known to strongly influence the distribution of glacier surface melt. Since melt inputs drive the formation and evolution of glacial drainage systems, it should follow that the drainage systems of debris-covered glaciers will differ from those of debris-free glaciers. This would have implications for the proglacial runoff regime,

An Artificial Antibody‐Based Toolbox Accelerates Validation of Hidden Microproteins Encoded by the Dark Genome

Advanced Science, EarlyView.
Microproteins are hidden treasures encoded by the “dark proteome” but remain largely underexplored due to the lack of highly efficient tools. We developed a molecularly imprinted polymers (MIPs)‐based toolbox (CLAIMID) to achieve accelerated and ultrasensitive microproteins validation at multiple biological scales (single living cells, cell populations,

Mapping Surface Temperatures on a Debris-Covered Glacier With an Unmanned Aerial Vehicle

Frontiers in Earth Science, 2018
A mantel of debris cover often accumulates across the surface of glaciers in active mountain ranges with exceptionally steep terrain, such as the Andes, Himalaya and New Zealand Alps.
