Debris-covered glaciers mapping based on machine learning and multi-source satellite images over Eastern Pamir

Big Earth Data
Debris-covered glaciers present significant challenges for accurately mapping and monitoring glacier dynamics, particularly in regions like the Eastern Pamir Plateau.

Quantification of dryland depositional environments across contrasting fluvio‐aeolian and fluvio‐lacustrine transects: An integrated subsurface and outcrop analogue study of the Organ Rock Formation, Utah, USA

Sedimentology, EarlyView.
ABSTRACT The standard subdivision of a distributive fluvial system (DFS) into proximal, medial and distal zones is typically based on the proportion of channel bodies and/or the degree of channel amalgamation, reflecting a downstream fining trend towards a mud‐prone terminal pinch‐out.

Mass-balance changes of the debris-covered glaciers in the Langtang Himal, Nepal, from 1974 to 1999 [PDF]

, 2015
Thick debris cover on glaciers can significantly reduce ice melt. However, several studies have suggested that debris-covered glaciers in the Himalaya might have lost mass at a rate similar to debris-free glaciers.

Glacial and periglacial landforms and their recent dynamics in the Las Veguitas catchment, Cordillera Frontal of the Andes (Argentina)

Frontiers in Earth Science
The semi-arid Andes of South America are characterized by large areas with glacial and periglacial environments. This study focuses on the distribution and recent dynamics of glacial and periglacial landforms in the Las Veguitas catchment (3000–5500 m ...

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 ...

Feedbacks and timescales in the modelled transient response of debris-covered glaciers [PDF]

The Cryosphere
Glaciers worldwide are becoming increasingly debris-covered, yet many aspects within the coupled glacier-debris system are not well-understood. While the insulating effect of continuous debris layers is well-known, the transient feedbacks with glacier ...

Tracking Invasive Pheretimoid Earthworm Species in New Brunswick, Canada: Impacts on Soil Properties and Other Invasive Earthworms

New Zealand Journal of Zoology, Volume 53, Issue 4, December 2026.
Jumping worms, a group of invasive earthworms, are spreading northward in North America, yet their impacts remain poorly understood, especially at their northern range limit. Following the initial detection of jumping worms in New Brunswick, we sampled 46 sites across the province to assess their regional spread and examine possible vectors of ...

Deriving seasonal and annual surface mass balance for debris-covered glaciers from flow-corrected satellite stereo DEM time series

Journal of Glaciology
Glaciers in High-Mountain Asia are experiencing varying rates and patterns of mass loss due to a complex interplay between glacier surface processes, local conditions and climate forcing.

Best Practices in Open and Reproducible Antarctic Marine Sediment Core Research

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Marine sediment cores from Antarctica are archived by national programs for reuse and resampling by future researchers, creating a resourceful way to conduct Antarctic science. With reduced budgets to conduct Antarctic field work and to collect new sediment cores offshore of the icy continent, the accessibility of these archived cores and ...
