GlacierNet: A Deep-Learning Approach for Debris-Covered Glacier Mapping [PDF]

IEEE Access, 2020
Rising global temperatures over the past decades is directly affecting glacier dynamics. To understand glacier fluctuations and document regional glacier-state trends, glacier-boundary detection is necessary. Debris-covered glacier (DCG) mapping, however, is notoriously difficult using conventional geospatial technology methods.

Influence of Supraglacial Debris Thickness on Thermal Resistance of the Glaciers of Chandra Basin, Western Himalaya

Frontiers in Earth Science, 2021
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.

Meteorology and surface energy fluxes in the 2005–2007 ablation seasons at the Miage debris-covered glacier, Mont Blanc Massif, Italian Alps

, 2010
During the 2005–2007 June–September ablation seasons, meteorological conditions were recorded on the lower and upper parts of the debris‐covered ablation zone of Miage Glacier, Italy. In 2005, debris temperature and subdebris ice melt were also monitored

Origin and significance of 'dispersed facies' basal ice: Svínafellsjökull, Iceland [PDF]

, 2010
Dispersed facies basal ice - massive (i.e. structureless) ice with dispersed debris aggregates - is present at the margins of many glaciers and, as a product of internal glacial processes, has the potential to provide important information about the ...

Debris thickness of glaciers in the Everest area (Nepal Himalaya) derived from satellite imagery using a nonlinear energy balance model [PDF]

The Cryosphere, 2014
Debris thickness is an important characteristic of debris-covered glaciers in the Everest region of the Himalayas. The debris thickness controls the melt rates of the glaciers, which has large implications for hydrologic models, the glaciers' response to

Representing moisture fluxes and phase changes in glacier debris cover using a reservoir approach

, 2014
Due to the complexity of treating moisture in supraglacial debris, surface energy balance models to date have neglected moisture infiltration and phase changes in the debris layer.

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.

Internal structure and water routing of an ice-debris landform assemblage using multiple geophysical methods in the semiarid Andes

Frontiers in Earth Science, 2023
Rock glaciers are the most abundant (peri) glacial landform in the semiarid Andes (SA, 29–34°S), covering about three times the area of mountain glaciers.

International Workshop Examines Debris‐covered Glaciers

Eos, Transactions American Geophysical Union, 2001
Glaciers are important features in climate studies. The smaller alpine glaciers respond to climatic variation in ways visible during the human lifetime. Glacial processes modify the landscape leaving signatures of past climatic conditions. The large ice sheets have an important role in the global heat and water balance, which in turn play a major role ...

Including debris cover effects in a distributed model of glacier ablation

, 2012
Distributed glacier melt models generally assume that the glacier surface consists of bare exposed ice and snow. In reality, many glaciers are wholly or partially covered in layers of debris that tend to suppress ablation rates.
