Carbon flux in supraglacial debris over two ablation seasons at Miage Glacier, Mont Blanc massif, European Alps

Frontiers in Earth Science, 2023
The cryosphere plays an important role in the global carbon cycle, but few studies have examined carbon fluxes specifically on debris-covered glaciers.

Stream hydrology controls on ice cliff evolution and survival on debris-covered glaciers [PDF]

Earth Surface Dynamics
Ice cliffs are melt hot spots that contribute disproportionately to melt on debris-covered glaciers. In this study, we investigate the impact of supraglacial stream hydrology on ice cliffs using in situ and remote sensing observations, streamflow ...

Perennially ice‐covered lake facies as proxies for ice cover properties and climate: Insights from Lake Joyce, Antarctica

Sedimentology, EarlyView.
ABSTRACT Process‐based depositional models for perennially ice‐covered lakes (PICLs) are important for interpreting palaeolake deposits and their connection to past climate. PICLs are only stable under specific climate states, and unlike other ice‐free or seasonally ice‐covered lakes, PICL deposits generally have bimodal grain sizes: mud introduced by ...

Spatiotemporal supraglacial pond and ice cliff changes in the Bhutan–Tibet border region from 2016 to 2018

Journal of Glaciology, 2022
Supraglacial ponds and ice cliffs can dramatically enhance ablation rates on debris-covered glaciers. Supraglacial ponds can also coalesce, forming moraine-dammed lakes at risk of glacial lake outburst flood (GLOF).

Modelling the evolution of Djankuat Glacier, North Caucasus, from 1752 until 2100 CE [PDF]

The Cryosphere, 2020
We use a numerical flow line model to simulate the behaviour of the Djankuat Glacier, a World Glacier Monitoring Service reference glacier situated in the North Caucasus (Republic of Kabardino-Balkaria, Russian Federation), in response to past, present ...

Lodge moraines: a common yet underreported end‐moraine type—a review

Boreas, Volume 55, Issue 4, Page 906-931, October 2026.
Lodge moraines are a distinct genetic type of end moraine formed by submarginal accretion of subglacial till; they are some of the largest end moraines in the world. Although underreported in the literature, they are of equal importance to push, dump and hummocky end moraines. End moraines are formed at glacier ice margins and show the extent of former

Listening to Tsunami Waves Induced by Glacier Calving

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Processes at the ice–ocean interface play a central role in regulating the stability of marine‐terminating glaciers and ice sheets and drive ocean freshening and mixing. Iceberg calving—a mechanical loss of ice—generates ocean waves and promotes water‐mass exchange in glacierized bays.

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

Journal 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 ...

First Empirical Assessment of Ice Content From a Himalayan Rock Glacier

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Climate warming and degradation of glaciers and permafrost in High Mountain Asia is threatening the sustainability of the region's natural “water towers” and allied ecosystems and infrastructure. Approximately 25,000 Himalayan rock glaciers exist and, being more resilient to climatic change than glaciers, they represent important freshwater ...

Global threats, local opportunities: ice‐related landforms provide refugia for high‐elevation plants and arthropods

Ecography, Volume 2026, Issue 9, September 2026.
Ice‐related landforms in mountain areas have been hypothesized to play a key role in the survival of cold‐adapted species threatened by climate change. However, our understanding of such landforms acting as refugia remains speculative. Here we analyse occurrence data, collected through a standardized sampling at 471 sampling points across the European ...
