Volume-area scaling for debris-covered glaciers [PDF]

open access: yesJournal of Glaciology, 2020
A volume-area scaling relation is commonly used to estimate glacier volume or its future changes on a global scale. The presence of an insulating supraglacial debris cover alters the mass-balance profile of a glacier, potentially modifying the scaling ...

Reduced melt on debris-covered glaciers: investigations from Changri Nup Glacier, Nepal [PDF]

open access: yesThe Cryosphere, 2016
Approximately 25 % of the glacierized area in the Everest region is covered by debris, yet the surface mass balance of debris-covered portions of these glaciers has not been measured directly. In this study, ground-based measurements of surface elevation

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

open access: yesNat Commun, 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

Modeling debris-covered glaciers: response to steady debris deposition [PDF]

open access: yesThe Cryosphere, 2016
Debris-covered glaciers are common in rapidly eroding alpine landscapes. When thicker than a few centimeters, surface debris suppresses melt rates. If continuous debris cover is present, ablation rates can be significantly reduced leading to increases in

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

open access: yesGeophysical Research Letters, 2023
Ice 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 ...

Warming Has Accelerated the Melting of Glaciers on the Tibetan Plateau, but the Debris-Covered Glaciers Are Rapidly Expanding

open access: yesRemote Sensing, 2022
Glacier changes on the Tibetan Plateau are of great importance for regional climate and hydrology and even global ecological changes. It is urgent to understand the effect of climate warming on both clean and debris-covered glaciers on the Tibetan ...

Debris Emergence Elevations and Glacier Change

open access: yesFrontiers in Earth Science, 2021
Debris-covered glaciers represent potentially significant stores of freshwater in river basins throughout High Mountain Asia (HMA). Direct glacier mass balance measurements are extremely difficult to maintain on debris-covered glaciers, and optical ...

Field-based research directions for investigating the interior of high-elevation debris-covered glaciers

open access: yesAnnals of Glaciology, 2022
The debris that covers the ablation areas of high-elevation debris-covered glaciers contributes to the distinctive features and processes occurring both on and within such glaciers.

Southwest-facing slopes control the formation of debris-covered glaciers in the Bhutan Himalaya [PDF]

open access: yesThe Cryosphere, 2013
To understand the formation conditions of debris-covered glaciers, we examined the dimension and shape of debris-covered areas and potential debris-supply (PDS) slopes of 213 glaciers in the Bhutan Himalaya.

The Challenge of Non-Stationary Feedbacks in Modeling the Response of Debris-Covered Glaciers to Climate Forcing

open access: yesFrontiers in Earth Science, 2021
Ongoing changes in mountain glaciers affect local water resources, hazard potential and global sea level. An increasing proportion of remaining mountain glaciers are affected by the presence of a surface cover of rock debris, and the response of these ...
