Low‐Frequency Polarization of Blank Ice Features in Solid Rocks

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract For hydrogeological management of seasonally frozen soils, or permafrost, the quantification of ice and water content is key. Changes in electrical conductivity are commonly used to monitor ice‐to‐water ratios but hard rocks, ice and air are all highly resistive materials.

Capturing soil moisture and salinity changes in flooded coastal forests using electrical resistivity and induced polarization

Vadose Zone Journal, Volume 25, Issue 1, January/February 2026.
Abstract Geophysical methods provide high‐resolution spatial measurements of physical quantities sensitive to changes in soil moisture and salinity and can be used to monitor soil hydrological responses to flooding. However, extracting quantitative hydrological information from geophysical data remains challenging.

Deep resistivity imaging across the Northern and Central belts of the Southern Uplands [PDF]

, 1995
Magnetotelluric data from 16 soundings have provided a northwest-southeast traverse across the Northern and Central belts of the Southern Uplands. The 34 km profile extends from the Ordovician Portpatrick Formation (northwest of the Thornhill Basin ...

Monitoring of the geomagnetic and geoelectric field in two regions of Greece for the detection of earthquake precursors

Annals of Geophysics, 1997
Two magnetotelluric stations have been installed in the South-Eastern Thessaly basin (Central Greece), which have recorded the geomagnetic and geoelectric fields since 1993.

Influence of geoelectric field on chemical reactions on Earth [PDF]

Reports of the National Academy of Sciences of Ukraine
The existing understanding of chemical thermodynamics presupposes that at the same temperature and other conditions being equal, the rate of a chemical reaction will always and everywhere on Earth be constant. We have found that geoelectric field generated by the Earth's ionosphere, is capable of exerting a strong influence on the rate of chemical ...

Regional Three‐Dimensional Magnetotelluric Electrical Resistivity Model of the Manica Greenstone Belt, Western Mozambique

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Magnetotelluric (MT) survey results from the Late Archean Manica greenstone belt, an extension of the Odzi‐Mutare greenstone belt of the Zimbabwe Craton, are presented. A total of 33 MT stations were acquired on an irregular grid with an average station spacing of approximately 5 km.

Study on the change characteristics of regional geoelectric fields

Journal of Earth System Science, 2019
In this study, we illustrate the temporal variations of the geoelectric field and geomagnetic field by data from eight geoelectric field stations and four geomagnetic field stations in Mainland China in 2011. The maximum entropy spectral estimation method (MEM) was used to process the data in our study. The results show that: (i) it is obvious seasonal

The Gannon Storm's Impact on Electric and Magnetic Fields in Italy: A Regional Perspective

Space Weather, Volume 24, Issue 1, January 2026.
Abstract The intense May 2024 geomagnetic storm provided an opportunity to conduct the first analysis of geoelectric hazards in Italy. Data from three geomagnetic observatories and a magnetotelluric station were analyzed to examine the spatiotemporal evolution of storm‐induced variations.

Study on the background characteristics of electric fields constrained by cross-sphere observations

Earth, Planets and Space
The interactions among Earth’s spheres constitute both the starting point and ultimate goal of Earth system science research. An in-depth investigation into these interactions is essential for advancing the interdisciplinary integration and collaborative

Review of geomagnetically induced currents

地球与行星物理论评, 2022
Geomagnetic disturbances caused by solar activities induce geoelectric fields on the earth's surface, which generate geomagnetically induced currents (GICs) in electrically conducting systems.
