Supraglacial Ice Cliffs Can Substantially Increase the Mass Loss of Debris‐Covered Glaciers

open access: yesGeophysical Research Letters, 2021
The thinning patterns of debris‐covered glaciers in High Mountain Asia are not well understood. Here we calculate the effect of supraglacial ice cliffs on the mass balance of all glaciers in a Himalayan catchment, using a process‐based ice cliff melt ...

Discriminating viscous-creep features (rock glaciers) in mountain permafrost from debris-covered glaciers – a commented test at the Gruben and Yerba Loca sites, Swiss Alps and Chilean Andes [PDF]

open access: yesThe Cryosphere
Viscous-flow features in perennially frozen talus/debris called rock glaciers are being systematically inventoried as part of the global climate-related monitoring of mountain permafrost.

Environmental Impact of Silicic Magmatism in Large Igneous Province Events

open access: yesGeophysical Monograph Series, Page 133-151., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Glacier branch lines and glacier ice thickness estimation for debris-covered glaciers in the Central Tien Shan

open access: yesJournal of Glaciology, 2018
Information about the ice volume stored in glaciers is of high importance for sustainable water management in many arid regions of Central Asia. Several methods to estimate the ice volume exist.

Modelling steady states and the transient response of debris-covered glaciers [PDF]

open access: yesThe Cryosphere, 2021
Debris-covered glaciers are commonly found in alpine landscapes of high relief and play an increasingly important role in a warming climate. As a result of the insulating effect of supraglacial debris, their response to changes in climate is less direct ...

DebDaB: a database of supraglacial debris thickness and physical properties [PDF]

open access: yesEarth System Science Data
Rocky debris covers around 7.3 % of the global glacier area, influencing ice melt rates and the surface mass balance of glaciers, making the dynamics and hydrology of debris-covered glaciers distinct from those of clean-ice glaciers.

Using ArcticDEM to Analyse the Dimensions and Dynamics of Debris-Covered Glaciers in Kamchatka, Russia

open access: yesGeosciences, 2018
On the Kamchatka Peninsula, a number of glaciers are covered by thick volcanic debris, which makes their margins difficult to delineate from satellite imagery. Fortunately, high resolution, multi-temporal digital surface models (DSMs) covering the entire

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 ...

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

open access: yesRemote 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 ...

Using climate reanalysis data in conjunction with multi-temporal satellite thermal imagery to derive supraglacial debris thickness changes from energy-balance modelling

open access: yesJournal of Glaciology, 2021
Surface energy-balance models are commonly used in conjunction with satellite thermal imagery to estimate supraglacial debris thickness. Removing the need for local meteorological data in the debris thickness estimation workflow could improve the ...
