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.

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.

The rise and fall of a volcanic plateau: Landscape evolution at the fringes of the former Patagonian Ice Sheet, Meseta Chile Chico, central Patagonian Andes

Journal of Quaternary Science, EarlyView.
ABSTRACT Understanding Earth‐surface processes along the fringes of large ice sheets is integral to deciphering cold‐region environmental variability and anticipating slope instability under climate change. We investigate the Meseta Chile Chico, a volcanic plateau in the central Patagonian Andes, located at the eastern margin of the former Patagonian ...

Pluri-decadal (1955–2014) evolution of glacier–rock glacier transitional landforms in the central Andes of Chile (30–33° S) [PDF]

Earth Surface Dynamics, 2017
Three glacier–rock glacier transitional landforms in the central Andes of Chile are investigated over the last decades in order to highlight and question the significance of their landscape and flow dynamics.

3D seismic imagery of a buried glacitectonic thrust complex in the North Sea and the dimensions of composite ridge systems in glaciated landscapes

Journal of Quaternary Science, EarlyView.
ABSTRACT Sets of sub‐parallel composite ridges in glaciated landscapes have long been regarded as landforms produced by glacitectonism, the brittle and ductile deformation of sediments at and immediately beyond glacier and ice‐sheet margins resulting from stresses produced by ice.

Landforms and sediments developed during the recent recession of debris-covered Ponkar Glacier, Nepal [PDF]

, 2022
Understanding the evolution of debris-covered glaciers in High Mountain Asia, the physical processes governing the effect of debris cover on mass balance, and the response of debris-covered glaciers to climatic change are key for assessing water ...

Novel Machine Learning Method Integrating Ensemble Learning and Deep Learning for Mapping Debris-Covered Glaciers

Remote Sensing, 2021
Glaciers in High Mountain Asia (HMA) have a significant impact on human activity. Thus, a detailed and up-to-date inventory of glaciers is crucial, along with monitoring them regularly.
