Four Decades of Reach‐Scale Declines in Total Phosphorus Across the Yellow River Basin Driven by Vegetation Restoration and Dam Impoundment

open access: yesWater Resources Research, Volume 62, Issue 10, October 2026.
Abstract Phosphorus (P) is a finite resource fundamental to terrestrial and aquatic productivity. However, excessive P transfer from land to rivers threatens food production and degrades water quality. Systematic analyses of multidecadal total phosphorus (TP) variation in large river basins remain challenging because of incomplete and non‐uniform ...

Frequency‐Domain Airborne Electromagnetic Imaging of Permafrost Reveals Heterogeneity and Drivers of Permafrost Change in the Discontinuous Permafrost Zone of Northwestern Canada

open access: yesAGU Advances, Volume 7, Issue 7, October 2026.
Abstract Northern permafrost landscapes are undergoing rapid warming and thaw, yet the three‐dimensional subsurface structure that governs thaw vulnerability and landscape response remains poorly resolved by conventional ground temperature monitoring and satellite remote sensing.

Rapid Increase in Geogenic CO2 Emissions from Antarctic Permafrost

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 10, October 2026.
Abstract Thawing permafrost can amplify climate change by releasing previously stored carbon, but observations of this feedback come mainly from the Arctic. Ice‐free Antarctic terrains are generally regarded as minor CO2 sources, although sub‐permafrost brines and deep carbon reservoirs may support localized geogenic degassing.

Fault‐Related Carbonates as Quaternary Seismotectonic and Paleoclimate Archives (Monte Marine Fault, Central Apennines)

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Seismogenic faults shape continental landscapes, drive crustal deformation and influence fluid exchange between the lithosphere and atmosphere. Yet, quantitative links between fault activity, exhumation and near‐surface environmental evolution remain poorly understood. Here, structural (meso‐ and micro‐scale) investigations are integrated with

Ground Penetrating Radar Observations of Subsurface Structures From the Makgadikgadi Pans (Botswana): A Terrestrial Analogue of Martian Playa Lakes

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Playa lakes are considered promising landing sites on Mars because of their strong astrobiological potential. Therefore, sediments and buried structures in terrestrial playa lakes have become the focus of numerous analogue studies. The inclusion of ground penetrating radar (GPR) in the payloads of Martian missions has opened new avenues for ...
