Morphology and sedimentology of murtooized terrain on the southern Fraser Plateau, British Columbia, Canada

Boreas, Volume 54, Issue 4, Page 625-648, October 2025.
Recent public releases of Light Detection and Ranging (LiDAR) data in south central British Columbia (BC), Canada have revealed several landforms resembling ‘murtoos’, previously identified across portions of Scandinavia. In this study, we investigate the morphology and sedimentology of these landforms, the first report of their kind associated with ...

Modeling the Impact of Mining Activities on the Dynamics and Evolution of a Kyrgyz Glacier

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 8, August 2025.
Abstract Glaciers worldwide are retreating because of climate change. However, local human activities also influence their dynamics. Here, we model the impact of gold mining operations on Davydov Glacier in the Inner Tien Shan, Kyrgyzstan, from the Little Ice Age through 2100 under different Shared Socioeconomic Pathway climate scenarios using a 3D ...

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.

First evidence of microplastic contamination in the supraglacial debris of an alpine glacier

Environmental Pollution, 2019
Contamination by plastic debris has been documented in most regions of the world, but their occurrence in high mountain areas has not been investigated to date. Here we present the first report of the occurrence and amount of microplastic in any terrestrial glacier environment. In the supraglacial debris of the Forni Glacier (Italian Alps), we observed

Phosphatase activity and organic phosphorus turnover on a high Arctic glacier [PDF]

Biogeosciences, 2009
Arctic glacier surfaces harbour abundant microbial communities consisting mainly of heterotrophic and photoautotrophic bacteria. The microbes must cope with low concentrations of nutrients and with the fact that both the dissolved and debris-bound ...

An investigation of the influence of supraglacial debris on glacier-hydrology

, 2015
Abstract. The influence of supraglacial debris on the rate and spatial distribution of glacier surface melt is well established, but its potential impact on the structure and evolution of the drainage system of extensively debris-covered glaciers has not been previously investigated.

In-situ and modelled debris thickness distribution on Panchi Nala Glacier (western Himalaya, India) and its impact on glacier state

Quaternary Science Advances
This study presents extensive in-situ debris thickness measurements over the Panchi Nala Glacier (western Himalaya, India) and models its spatial distribution using remote sensing and ERA-5 reanalysis data.

Ground-penetrating radar measurements of debris thickness on Lirung Glacier, Nepal

Journal of Glaciology, 2017
Supraglacial debris thickness is a key control on the surface energy balance of debris-covered glaciers, yet debris thickness measurements are sparse due to difficulties of data collection.

Debris covered glacier mapping using newly annotated multisource remote sensing data and geo-foundational model

Science of Remote Sensing
The automated mapping of debris covered glaciers remains challenging due to spectral similarity between supraglacial debris (on-glaciers) and periglacial debris (off-glaciers).

Numerical study of the error sources in the experimental estimation of thermal diffusivity: an application to debris-covered glaciers [PDF]

The Cryosphere
A surface debris layer significantly modifies underlying ice melt dependent on the thermal resistance of the debris cover, with thermal resistance being a function of debris thickness and effective thermal conductivity.
