Processes at the margins of supraglacial debris cover: Quantifying dirty ice ablation and debris redistribution [PDF]

Earth Surface Processes and Landforms, 2020
AbstractCurrent glacier ablation models have difficulty simulating the high‐melt transition zone between clean and debris‐covered ice. In this zone, thin debris cover is thought to increase ablation compared to clean ice, but often this cover is patchy rather than continuous. There is a need to understand ablation and debris dynamics in this transition

Interdecadal glacier inventories in the Karakoram since the 1990s [PDF]

Earth System Science Data, 2023
Multi-temporal glacier inventories provide key information about the glaciers, their characteristics, and changes and are inevitable for glacier modelling and investigating geodetic mass changes.

The impact of supraglacial debris on proglacial runoff and water chemistry [PDF]

Journal of Hydrology, 2019
Debris is known to influence the ablation, topography and hydrological systems of glaciers. This paper determines for the first time how these influences impact on bulk water routing and the proglacial runoff signal, using analyses of supraglacial and proglacial water chemistry and proglacial discharge at Miage Glacier, Italian Alps.

Detecting supraglacial debris thickness with GPR under suboptimal conditions [PDF]

Journal of Glaciology, 2021
The thickness of a supraglacial layer is critical to the magnitude and time frame of glacier melt. Field-based, short pulse, ground-penetrating radar (GPR) has successfully measured debris thickness during a glacier's melt season, when there is a strong return from the ice–debris interface, but profiling with GPR in the absence of a highly reflective ...

Brief communication: Supraglacial debris-cover changes in the Caucasus Mountains [PDF]

, 2019
Abstract. Debris cover on glaciers can significantly alter melt, and hence, glacier mass balance and runoff. Debris coverage typically increases with shrinking glaciers. Here, we present data on debris cover and its changes for 559 glaciers located in different regions of the Greater Caucasus mountains based on 1986, 2000 and 2014 Landsat and SPOT ...

Physical, chemical, and biological characteristics of supraglacial pools on a debris-covered glacier in Mt. Gongga, Tibetan Plateau

Arctic, Antarctic, and Alpine Research, 2020
Meltwater habitats are found on glacier surfaces worldwide, but much of the current understanding of these habitats comes from clean glaciers sprinkled with cryoconite.

Supraglacial ice cliffs and ponds on debris-covered glaciers: spatio-temporal distribution and characteristics [PDF]

Journal of Glaciology, 2019
ABSTRACTIce cliffs and ponds on debris-covered glaciers have received increased attention due to their role in amplifying local melt. However, very few studies have looked at these features on the catchment scale to determine their patterns and changes in space and time.

Ablation Patterns of the Debris Covered Tongue of Halong Glacier Revealed by Short Term Unmanned Aerial Vehicle Surveys

Frontiers in Earth Science, 2021
Debris-covered glaciers are an important glacier type and have attracted more and more attention. This study presents the results of ablation patterns of debris-covered tongue of the Halong Glacier in the northeastern Tibetan Plateau, by using two ...

Changes in glacier surface cover on Baltoro glacier, Karakoram, north Pakistan, 2001–2012

Journal of Maps, 2017
The presence of supraglacial debris on glaciers in the Himalaya-Karakoram affects the ablation rate of these glaciers and their response to climatic change. To understand how supraglacial debris distribution and associated surface features vary spatially

The New Swiss Glacier Inventory SGI2016: From a Topographical to a Glaciological Dataset

Frontiers in Earth Science, 2021
Glaciers in Switzerland are shrinking rapidly in response to ongoing climate change. Repeated glacier inventories are key to monitor such changes at the regional scale. Here we present the new Swiss Glacier Inventory 2016 (SGI2016) that has been acquired
