Distributed Melt on a Debris-Covered Glacier: Field Observations and Melt Modeling on the Lirung Glacier in the Himalaya [PDF]

Frontiers in Earth Science, 2021
Debris-covered glaciers, especially in high-mountain Asia, have received increased attention in recent years. So far, few field-based observations of distributed mass loss exist and both the properties of the debris layer as well as the atmospheric ...

Glaciation of Alpine Valleys: The Glacier – Debris-Covered Glacier – Rock Glacier Continuum

Geomorphology, 2018
Alpine ice varies from pure ice glaciers to partially debris-covered glaciers to rock glaciers, as defined by the degree of debris cover. In many low- to mid-latitude mountain ranges, the few bare ice glaciers that do exist in the present climate are ...

Controls on the relative melt rates of debris-covered glacier surfaces

Environmental 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 ...

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

iScience
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 ...

The Causes of Debris-Covered Glacier Thinning: Evidence for the Importance of Ice Dynamics From Kennicott Glacier, Alaska

Frontiers in Earth Science, 2021
The cause of debris-covered glacier thinning remains controversial. One hypothesis asserts that melt hotspots (ice cliffs, ponds, or thin debris) increase thinning, while the other posits that declining ice flow leads to dynamic thinning under thick ...

Polythermal structure of a Himalayan debris-covered glacier revealed by borehole thermometry. [PDF]

Sci Rep, 2018
Runoff from high-elevation debris-covered glaciers represents a crucial water supply for millions of people in the Hindu Kush-Himalaya region, where peak water has already passed in places.

Meteorological impacts of a novel debris‐covered glacier category in a regional climate model across a Himalayan catchment

Atmospheric Science Letters, 2021
Many of the glaciers in the Nepalese Himalaya are partially covered in a layer of loose rock known as debris cover. In the Dudh Koshi River Basin, Nepal, approximately 25% of glaciers are debris‐covered.

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

Scientific 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 ...

Internal structure and current evolution of very small debris-covered glacier systems located in alpine permafrost environments

Frontiers in Earth Science, 2016
This contribution explores the internal structure of very small debris-covered glacier systems located in permafrost environments and their current dynamical responses to short-term climatic variations.

Debris-covered glacier energy balance model for Imja–Lhotse Shar Glacier in the Everest region of Nepal [PDF]

The Cryosphere, 2015
Debris thickness plays an important role in regulating ablation rates on debris-covered glaciers as well as controlling the likely size and location of supraglacial lakes.
