Modelling the effects of space weather at the Earth’s surface : a UK geoelectric field model [PDF]
, 2004 Geomagnetically Induced Currents (GIC), which can flow in technological systems such as power transmission grids, are a consequence of the geoelectric field induced at the surface of the Earth during geomagnetic storms.

Geophysical investigation of the Santa Marta impact structure—Piauí State, Brazil
Meteoritics &Planetary Science, EarlyView.Abstract The Santa Marta impact structure in northeastern Brazil, recognized as a partially preserved complex crater, was investigated through an integrated geophysical study employing magnetotelluric (MT) and gravity methods. Our research provides constraints on the crater's subsurface architecture.

Strong geomagnetic disturbances and induced currents on Earth surface [PDF]
, 2008 Long-term variations in strong geomagnetic storms are analyzed and linked to electric fields induced on Earth. In fact, geomagnetic disturbances generate electric fields that drive currents in the Earth which may have significant effects on electrical ...

Effect of positional inaccuracies on multielectrode results [PDF]
, 2008 This paper investigates the effect of electrode positioning errors on the inverted pseudosection. Instead of random spacing errors (as usually assumed in geoelectrics) we exactly measured this effect among field conditions.

Relationship between Interplanetary Conditions and Changes in the Geomagnetic Field to Understand the Causes of Geomagnetically Induced Currents [PDF]
, 2018 Geomagnetically Induced Currents (GICs) are electrical currents induced in ground-level conductive networks, like power lines and pipelines, which can cause costly damage to infrastructure.

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.Abstract Conventional numerical methods for computing three‐dimensional (3D) airborne transient electromagnetic (ATEM) forward modeling suffer from low computational efficiency and high computational cost. Although deep learning techniques have achieved some progress in accelerating low‐dimensional ATEM forward modeling, high‐accuracy and efficient 3D ...

The detection and tracking of mine-water pollution from abandoned mines using electrical tomography [PDF]
, 2009 Increasing emphasis is being placed on the environmental and societal impact of mining, particularly in the EU, where the environmental impacts of abandoned mine sites (spoil heaps and tailings) are now subject to the legally binding Water Framework and ...

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract Fugitive methane leakage from legacy oil and gas wells is assessed using surface flux and soil‐gas measurements, yet these signals are modulated by meteorology and shallow processes, obscuring sustained leakage. Whether persistent leakage leaves a coherent imprint in the shallow subsurface remains unresolved. Here we present a multi‐year field
