Comparison of Electromagnetic Induction and Electrical Resistivity Tomography in Assessing Soil Salinity: Insights from Four Plots with Distinct Soil Salinity Levels

Land
Electromagnetic induction (EMI) and electrical resistivity tomography (ERT) are geophysical techniques measuring soil electrical conductivity and providing insights into properties correlated with it to depths of several meters. EMI measures the apparent

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

AGU 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.

Investigating the relationship between resistivity tomography and methane emissions in a controlled dumpsite: A comprehensive study of resistivity profiles

Results in Engineering
Controlled dumping––a widespread practice in developing countries––inadequately manages emissions of methane (CH4), a greenhouse gas (GHG) that contributes significantly to global warming.

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

Journal 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 ...

Characterizing Permafrost Distribution Along the Hudson Bay Railway Using Temperature‐Calibrated Electrical Resistivity Tomography

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract As the climate warms, understanding permafrost distribution along linear infrastructure is a key aspect of assessing, mitigating, and adapting to the risks associated with permafrost thaw. Electrical resistivity tomography (ERT) is becoming an increasingly common tool for evaluating permafrost distribution at the infrastructure scale.

Palaeoenvironmental and climatic changes from the lateglacial of the Saalian to the Late Weichselian in central Poland: a multiproxy study from Józefów

Boreas, Volume 55, Issue 4, Page 1073-1101, October 2026.
Józefów site is a case study which provides a detailed record of environmental and climate changes and confirms the main traces of the landscape morphogenesis of the Late Pleistocene established in central‐eastern Europe. This study presents a multiproxy reconstruction of palaeoenvironment under variable climatic conditions from the retreat of the ...

Permafrost Detachment Slides: A Distinct High‐Magnitude Permafrost Mass Wasting Process

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Warming permafrost is destabilizing landscapes, intensifying thaw‐driven mass wasting and giving rise to novel landslide forms. We characterize two recent (2017 and 2018), deep‐seated translational failures that we term Permafrost Detachment Slides (PDSs), which rapidly translocated 4.5 and 18 × 106 m3 of frozen material into downstream ...
