Carbon Cycle Succession Across a Permafrost Thaw Gradient in Northeastern Alberta as Revealed by δ13C in Dissolved Solids, Gases, and Particulates in Lakes

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract δ13C in particulate organic carbon (POC), dissolved organic carbon (DOC), dissolved inorganic carbon (DIC), carbon dioxide (CO2(g)) and methane (CH4(g)), together with geochemical modeling, were applied to describe carbon cycle evolution in 40 boreal lakes situated across a permafrost thaw gradient in northeastern Alberta, Canada, where ...

Using Texture‐Based Image Segmentation and Machine Learning With High‐Resolution Satellite Imagery to Assess Permafrost Degradation Landforms in the Russian High Arctic

Journal of Geophysical Research: Machine Learning and Computation
Amplified climate change across the Arctic causes significant permafrost thaw and an increase of permafrost degradation landforms. These landforms range from fine‐scale degrading ice wedge‐polygon‐networks to large‐scale features such as thermo‐erosional

A Causal‐Spatial Explainability Framework for Geological Hazard Susceptibility Modeling

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Data‐driven susceptibility models often act as black boxes, predicting where hazards may occur without explaining why. To address this gap, we propose a Causal‐Prior (CP) framework that integrates validated causal knowledge into training while yielding spatially grounded explanations.

Soft‐bedded ice sheet in hummocky terrain of north‐central Poland: Origin of rim ridges and subglacial processes

Sedimentology, Volume 73, Issue 2, Page 540-559, February 2026.
ABSTRACT Hummocky terrains are characterised by various geomorphological features that typically record processes associated with the downwasting of ice sheets. Common landforms in these areas include ramparts, linear ridges, kettle holes and ice‐walled lake plains.

Estimating Soil Electrical Parameters in the Canadian High Arctic From Impedance Measurements of the MIST Antenna Above the Surface

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The MIST experiment aims to detect the cosmological 21‐cm signal through sky observations at 25–125 MHz using a wide‐beam antenna. The antenna is mounted above the soil and the beam characteristics are highly dependent on the soil's electrical properties.

DARTS: Multi-year database of AI-detected retrogressive thaw slumps in the circum-arctic permafrost region

Scientific Data
Retrogressive Thaw Slumps (RTS) are widespread mass-wasting hillslope failures triggered by thawing permafrost. While regional studies have provided insights into the spatial distribution and dynamics of RTS, a consistent and unbiased quantification and ...
