Dynamics of debris-covered glaciers

, 2021
The presence of a supraglacial debris layer affects the melt of underlying ice which causes debris-covered glaciers to respond differently to climate forcing compared to clean-ice glaciers.

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 ...

Spatial and temporal distribution of glaciers, debris-covered glaciers and rock glaciers during the last deglaciation in the Valley of the Bonaigua (Central Pyrenees)

Cuadernos de Investigación Geográfica, 2020
The application of the paleogeographic method to the study of glacial landforms and rock glaciers allows their morphometric and sedimentological characterization, the establishment of a detailed morphostratigraphic sequence and a chronological proposal ...

Classification of debris-covered glaciers and rock glaciers in the Andes of central Chile [PDF]

, 2015
Artículo de publicación ISIIn the Dry Andes of Chile (17 to 35 degrees S), debris-covered glaciers and rock glaciers are differentiated from true glaciers based on the percentage of surface debris cover, thickness of surface debris, and ice content ...

Mapping of Supra-Glacial Debris Cover in the Greater Caucasus: A Semi-Automated Multi-Sensor Approach

Geosciences
Supra-glacial debris cover is important for the control of surface ice melt and glacier retreat in mountain regions. Despite the progress in techniques based on various satellite imagery, the mapping of debris-covered glacier boundaries over large ...

Thickness estimation of supraglacial debris above ice cliff exposures using a high-resolution digital surface model derived from terrestrial photography

Journal of Glaciology, 2017
The thickness of supraglacial debris cover controls how it impacts the ablation rate of underlying glacier ice, yet this quantity remains challenging to measure, particularly at glacier scales.

Ridges on martian debris-covered glaciers : deconvolving structural and climate processes [PDF]

, 2017
Debris-covered glaciers on Earth and Mars often exhibit surface ridges transverse to the flow direction of the glacier. The formation mechanism of these ridges is not well established, but some evidence from terrestrial analogues supports the idea that ...

Surface facies analysis of the Gangotri and neighbouring glaciers, central Himalaya

Science of Remote Sensing
Glaciers are primarily monitored using medium-to-high resolution satellite data, undermining the potential of coarse-resolution data. In pursuance of this, high resolution 10 m super-resolved glacier maps derived from 56 m coarse-resolution AWiFS data ...

A low-cost and open-source approach for supraglacial debris thickness mapping using UAV-based infrared thermography [PDF]

The Cryosphere
Debris-covered glaciers exist in many mountain ranges and play an important role in the regional water cycle. However, modelling the surface mass balance, runoff contribution and future evolution of debris-covered glaciers is fraught with uncertainty as ...
