Quantifying Spatiotemporal Changes in Supraglacial Debris Cover in Eastern Pamir from 1994 to 2024 Based on the Google Earth Engine

Remote Sensing
Supraglacial debris cover considerably influences sub-debris ablation patterns and the surface morphology of glaciers by modulating the land–atmosphere energy exchange.

Influence of Glaciological Structures on the Spatial Distribution of Cryoconite Holes, Northern Victoria Land, East Antarctica

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 12, December 2025.
Abstract Three blue‐ice areas in the upper reaches of Rennick Glacier, East Antarctica, are investigated using satellite remote sensing to assess the influence of meso‐ to large‐scale glaciological structures on cryoconite hole distributions. In total, 15,299 cryoconite holes and 1 600 structures were geospatially analyzed, which indicate that ...

Lichen Growth on Supraglacial Debris and its Implications for Lichenometric Studies [PDF]

Journal of Glaciology, 1978
AbstractLichens were found growing on some of the supraglacial debris of six small, active, retreating valley glaciers in southern Norway. The circumstances permitting their growth are discussed, as is the possibility of their surviving pro-glacial deposition under current and past conditions.

The assessment of the recent mass balance anomaly of Adishi glacier in the Central Caucasus by satellite altimetry

Earth Surface Processes and Landforms, Volume 50, Issue 13, October 2025.
Satellite altimetry shows a mass balance anomaly on Adishi Glacier, with localized thickening contrasting regional losses in the Central Caucasus. Favourable glacier hypsometry and the orographic effect of snow accumulation under the prevailing wind conditions emerge as key drivers, underlining the role of local processes in shaping glacier‐climate ...

Mapping Debris-Covered Glaciers Using High-Resolution Imagery (GF-2) and Deep Learning Algorithms

Remote Sensing
Glacier inventories are fundamental in understanding glacier dynamics and glacier-related environmental processes. High-resolution mapping of glacier outlines is lacking, although high-resolution satellite images have become available in recent decades ...

Role of Sparsely Glacierized Basins and Groundwater in Semiarid Andes Periglacial Headwaters

Hydrological Processes, Volume 39, Issue 10, October 2025.
This study highlights for the first time the role of the Andean low‐glacierized headwater basin in providing significant water flow to the outlet discharge (20%–30%) with relatively long residence times (several decades). It can be explained by unknown permafrost bodies, which must be better characterized to manage water in a changing climate in ...

Spatial, seasonal and interannual variability of supraglacial ponds in the Langtang Valley of Nepal, 1999–2013

Journal of Glaciology, 2017
Supraglacial ponds play a key role in absorbing atmospheric energy and directing it to the ice of debris-covered glaciers, but the spatial and temporal distribution of these features is not well documented.

Regional Ice‐Depth and Thickness in Phlegra Montes, Mars From Radar Characterization of Glacial Landsystems Using SHARAD

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract Morphological analyses of Viscous Flow Features (VFFs) in the mid‐latitude regions of Mars have led to the hypothesis that these landforms are equivalent to debris‐covered glaciers. Phlegra Montes is a 1400‐km‐long mountain range in the northern mid‐latitudes that spans from 30° to 50°N, where there is an abundance of glacial landsystems ...

Microbial Communities in Sediments From Different Landform Systems, Svalbard

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 10, October 2025.
Abstract Svalbard is host to a range of glacier types with different thermal regimes, behaviors and complex hydrological networks and landforms. Here, we hypothesize that the (H1) surge‐type glaciers will host different microbial community structures, and that (H2) different landform types will also host different microbial community structures.
