Glacio-limnological interactions at lake-calving glaciers [PDF]

, 2012
Iceberg calving is an efficient ablation process which introduces mechanical instability to glacier systems and can cause non-linear climatic response.

Correcting Unwrapping Errors Toward Reliable Rock Glacier Velocity From InSAR Time Series

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Rock Glacier Velocity is an Essential Climate Variable Permafrost Quantity, providing a quantifiable indicator of mountain permafrost evolution. Despite its wide usage, multi‐temporal InSAR often substantially underestimates rock glacier velocities compared to ground‐based measurements, limiting its reliability.

Application of a simplified energy-balance and heat-transfer model to simulate sub-debris melt on the Djankuat Glacier, Caucasus

Journal of Glaciology
Supraglacial debris strongly modifies melt rates on debris-covered glaciers, yet simulating this effect remains challenging because modelling the full surface energy balance (SEB) and the vertical conduction of heat through the debris layer requires many

High‐Resolution Temperature and Precipitation Variability in Northeast Asia Since the Last Glacial Maximum Recorded in an Annually Laminated Maar Lake

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Temperature and precipitation variability in monsoonal Asia is central to understanding regional climate dynamics and global teleconnections. How post‐LGM warming and hydroclimate change unfolded in Northeast Asia, and how they were linked to external forcing, remain poorly constrained.

High‐ and Low‐Latitude Insolation Forcing Drives the Half‐Precession Cycle in Winter Arctic Sea Ice

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract The half‐precession cycle is a key climatic signal in global climate system, linking high‐ and low‐latitude climate variability and bridging orbital‐ and millennial‐scale climate changes. While it characterizes tropical insolation, its origin in high‐latitude climate records remains unclear. Based on a transient climate simulation spanning the

Debris-covered glaciers as habitat for plant and arthropod species : environmental framework and colonization patterns

, 2017
Debris-covered glaciers are glaciers with the largest part of the ablation zone covered by a debris layer. Recent papers showed that debris-covered glaciers are able to support plant and arthropod life, advancing the hypothesis that such landforms could ...

Comparing the evolution of debris-free and debris-covered glaciers during the end of the Lateglacial and the Holocene in Dudh Koshi basin, Everest region, Nepal

International audienceDebris-covered glaciers are very frequent geomorphological features in Khumbu Himal (Nepal). Rock debris on the glacier surface play a significant role in glacier-climate relationships and glacier dynamics.

Heat Flux Modeling on Debris-Covered Glaciers

, 2011
A one-dimensional heat flux model has been developed in this study to analyze changes in heat propagation within debris cover on a glacier and the subsequent melt. The model can accept data collected in situ for calculations of real modeled melt, and also synthetic data based on simple wave forms and debris physical characteristics.
