Debris-covered glacier identification in the Karakoram aided by thermal remote sensing [PDF]

open access: yesiScience
Summary: Glacier changes in the Karakoram Mountain (KM) region were analyzed using Landsat images from 2000 to 2021. Clean ice boundaries were mapped using supervised classification, while debris-covered ice was identified by integrating surface ...

A comparison of glacier melt on debris-covered glaciers in the northern and southern Caucasus [PDF]

open access: yesThe Cryosphere, 2011
Abstract. The glacier coverage in the Caucasus Mountains underwent considerable changes during the last decades. In some regions, the observed reduction in glacier area is comparable to those in the European Alps and the extent of supra-glacial debris increased on many glaciers.

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 the relative melt rates of debris-covered glacier surfaces [PDF]

open access: yesEnvironmental Research Letters, 2022
Supraglacial debris covers 7% of mountain glacier area globally and generally reduces glacier surface melt. Enhanced energy absorption at ice cliffs and supraglacial ponds scattered across the debris surface leads these features to contribute ...

New inventory of glaciers in Tajikistan from 3 m PlanetScope imagery (2024): the Tajikistan Glacier Inventory (TGI) [PDF]

open access: yesScientific Data
Glaciers in Tajikistan serve as a crucial water source in Central Asia. However, existing glacier data products suffer from several limitations, including outdated temporal coverage, coarse spatial resolution, and inadequate mapping of debris-covered ...

Modelling runoff from a Himalayan debris-covered glacier [PDF]

open access: yesHydrology and Earth System Sciences, 2014
Although the processes by which glacial debris mantles alter the melting of glacier ice have been well studied, the mass balance and runoff patterns of Himalayan debris-covered glaciers and the response of these factors to climate change are not well ...

Surface composition of debris-covered glaciers across the Himalaya using linear spectral unmixing of Landsat 8 OLI imagery [PDF]

open access: yesThe Cryosphere, 2021
The Himalaya mountain range is characterized by highly glacierized, complex, dynamic topography. The ablation area of Himalayan glaciers often features a highly heterogeneous debris mantle comprising ponds, steep and shallow slopes of various aspects ...

Understanding Complex Debris-Covered Glaciers: Concepts, Issues, and Research Directions

open access: yesFrontiers in Earth Science, 2021
Understanding the climate-glacier dynamics of debris-covered glaciers is notoriously difficult given a multitude of controlling factors and feedback mechanisms involving climate forcing, debris-load properties, supraglacial water bodies, and multi-scale ...

CONCEPTUAL FRAMEWORK OF COMBINED PIXEL AND OBJECT-BASED METHOD FOR DELINEATION OF DEBRIS-COVERED GLACIERS [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Delineation of the glacier is an important task for understanding response of glaciers to climate. In Himalayan region, most of the glaciers are covered with debris.

The Concept of Steady State, Cyclicity and Debris Unloading of Debris-Covered Glaciers

open access: yesFrontiers in Earth Science, 2021
It can easily be expected that debris-covered glaciers show a different response on external forcing compared to clean-surface glaciers. The supra-glacial debris cover acts as an additional transfer layer for the energy exchange between atmosphere and ...
