Mapping Debris-Covered Glaciers Using High-Resolution Imagery (GF-2) and Deep Learning Algorithms

Remote Sensing
Glacier inventories are fundamental in understanding glacier dynamics and glacier-related environmental processes. High-resolution mapping of glacier outlines is lacking, although high-resolution satellite images have become available in recent decades ...

Rapid sequestration of rock avalanche deposits within glaciers

, 2015
Topographic development in mountainous landscapes is a complex interplay between tectonics, climate and denudation. Glaciers erode valleys to generate headwall relief, and hillslope processes control the height and retreat of the peaks.

Supraglacial Ponds Regulate Runoff From Himalayan Debris‐Covered Glaciers [PDF]

Geophysical Research Letters, 2017
AbstractMeltwater and runoff from glaciers in High Mountain Asia is a vital freshwater resource for one‐fifth of the Earth's population. Between 13% and 36% of the region's glacierized areas exhibit surface debris cover and associated supraglacial ponds whose hydrological buffering roles remain unconstrained.

Observations on a Debris-Covered Polar Glacier “Whisky Glacier”, James Ross Island, Antarctic Peninsula, Antarctica

, 1987
“Whisky Glacier” on James Ross Island, Antarctic Peninsula, comprises anévéand clean ice trunk surrounded by an extensive area of debris-covered ice resembling a rock glacier. The debris-free trunk of the glacier abuts abruptly against the broad, totally

Assessing glacier retreat and landform production at the ‘debris-charged’ snout of Kvíárjökull, Iceland [PDF]

, 2010
Iceland is a critical location for the study of glacier fluctuations and landform production in response to climate change due to its diverse glacial legacy and its archive of aerial photographs that provide accurately dated records of glacier retreat ...

Spatial Distribution and Characteristics of Debris-Covered Glaciers in Xinjiang Based on CGI-XJ2020

Remote Sensing
Debris cover is widespread on glaciers and strongly alters their surface albedo, energy balance, and ablation. Using the Chinese Glacier Inventory of Xinjiang 2020 (CGI-XJ2020), this study investigates the spatial distribution of debris-covered glaciers ...

Modelling the dynamics and evolution of debris-covered glaciers

, 2022
Debris-covered glaciers are found in most of the world’s glacierized areas. The presence of debris on the glacier surface affects the ablation rate of the underlying ice. When the debris cover exceeds a thickness of a few centimetres, thermal insulation becomes dominant, thereby reducing the ablation of the underlying ice so that for a given climate ...

Comment: a test of the englacial thrusting hypothesis of ;hummocky' moraine formation [PDF]

, 2007
Areas of apparently chaotically organised moraine mounds and ridges are commonly associated with British Younger Dryas glaciers, and are also found at many contemporary glacier margins (Boulton & Eyles 1979; Benn 1992; Bennett & Boulton 1993b; Hambrey et

A 70 year chronicle of the evolution of Echaurren Norte Glacier, Central Andes of Chile

Annals of Glaciology
The Echaurren Norte Glacier mass balance time series is the longest in the Southern Hemisphere, thus it is—together with the Zongo Glacier in Bolivia—a reference glacier by the World Glacier Monitoring Service.
