Long‐term evaluation of drywell managed aquifer recharge behavior using geoelectrical monitoring

Vadose Zone Journal, Volume 25, Issue 5, September/October 2026.
Abstract Drywells are a low‐footprint managed aquifer recharge technique with promise for recharging aquifers in California's Central Valley, where groundwater depletion has lowered the water table to more than 70‐m depth in some areas. To study the efficacy of drywells for recharge, we installed and instrumented a set of five drywells outside Fresno ...

Comparison of instruments for geoelectrical soil mapping at the field scale [PDF]

Near Surface Geophysics, 2009
In precision agriculture geoelectrical methods have shown their capability to detect spatial variation of important physico‐chemical soil parameters in an efficient way. Nevertheless, relationships between the electrical parameters (electrical conductivity or resistivity) and other soil properties are not always consistent over different fields.

Estimating Geomagnetically Induced Currents in Southern Brazil Using 3‐D Earth Resistivity Model

Space Weather, 2023
Geomagnetically induced currents (GICs) result from the interaction of the time variation of ground magnetic field during a geomagnetic disturbance with the Earth's deep electrical resistivity structure.

Toward an Improved Understanding of the Antarctic Coastal Zone and Its Contribution to Future Global Sea Level

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Understanding the coastal zone of the Antarctic Ice Sheet (AIS), where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica's influence on the global climate and sea level. This region has multiple tipping mechanisms that could trigger large, rapid, and potentially irreversible changes in the AIS ...

Geophysical Investigation of a Thermal Field in Abu Dhabi, United Arab Emirates

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract In the Abu Dhabi Emirate, near Madinat Zayed and Liwa, studies have identified high geothermal gradients and high‐heat‐flow areas. Assessing the geothermal potential in this region requires a detailed mapping of subsurface geological formations and their thermal properties.

Factor analysis of multi−electrode geoelectric field data

Multidiszciplináris tudományok, 2022
The paper presents the results of the factor analysis of multi-electrode geoelectric data measured in the area of the Surány aquifer. The 9-variable dataset measured on the first profile was examined by factor analysis using 2, 3, 4 and 5 factors. The calculations show that the Factor profile 1 carries the effects of IP (Induced Polarization), while ...

Numerical Investigations of Low‐Latitude Ground Magnetic Fields Due To Cavity Mode Oscillations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Pi2 oscillations are known to be associated with cavity mode oscillations (CMOs) in the inner magnetosphere at low latitudes. CMOs can also be excited by interplanetary shocks on the dayside. We present results from a global linear MHD wave model in spherical coordinates that allows us to analyze these waves at equatorial latitudes.

Comparison of Geoelectric Fields Computed by the Complex Image, Magnetotelluric, and Finite‐Difference Time‐Domain Methods

Space Weather
It is important to be able to accurately predict geoelectric field behavior so that potential space weather hazards to large grounded infrastructure, such as electric power grids, smart grids, oil and gas pipelines, and railway systems, can be better ...
