Evaluating Testability of Permafrost Models Through Physical and Thermal Testing in Complex Mountain Terrain, Yukon, Canada

Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 570-591, October/December 2026.
ABSTRACT Due to its subsurface nature, permafrost cannot be directly observed with the naked eye or optical remote sensing. Consequently, accurately describing its distribution and thermal state is challenging. This is especially true in vast, remote environments, where obtaining comprehensive field data is demanding or improbable.

Seismic Versus Sub‐Seismic Experimental Mirror‐Like Fault Surfaces in Bituminous Dolostones

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Mirror‐like Surfaces (MSs) are ultra‐polished surfaces frequently found in exhumed seismogenic fault zones in carbonates. They form over a wide range of pressure‐temperature conditions and slip rates, from seismic (≈1 m/s) to sub‐seismic (≈0.1–100 μm/s), reflecting distinct phases of the seismic cycle.

NH4‐Smectites as Potential Precursors of Nitrogen Compounds Evolved During Analyses by the Sample Analysis at Mars (SAM) Instrument on the Curiosity Rover

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Ammonium (NH4+) in the interlayer space of phyllosilicates has been proposed as a potential but underexplored nitrogen reservoir on Mars. We synthesized ammonium‐exchanged smectites (montmorillonite SWy‐2 and nontronite NAu‐2) and analyzed them, both as pure phases and in mixtures containing five or 20 wt.% magnesium (Mg) perchlorate, under ...

Strong‐Acid Weathering in a Carbonate‐Siliciclastic Cropland Diminishes Removal of CO2 From the Atmosphere Without Becoming a CO2 Source

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract One strategy to remove carbon dioxide (CO2) from the atmosphere is to accelerate weathering in croplands by adding powdered rock. Both silicate and carbonate minerals can be effective as amendments, but strong acids from rain and fertilizer diminish CO2 removal and can promote degassing of CO2 from carbonate minerals (geogenic CO2).

Organic Matter Dynamics and Biogeochemical Signatures in Lakes From the Prairies to Tundra in Western Canada

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract Climate‐driven poleward shifts of terrestrial ecosystems are expected to alter organic matter inputs and biogeochemical processes in northern lakes. In regions lacking long‐term observations, latitudinal gradients provide valuable space‐for‐time substitutions for predicting these changes.
