The Geomagnetic Storm on 10–12 May 2024 and Its Effect on the Swedish Power Grid

open access: yesSpace Weather, Volume 24, Issue 2, February 2026.
Abstract On 10–12 May 2024, at least five interplanetary coronal mass ejections (ICMEs) arrived at Earth and caused the strongest geomagnetic storm in over 20 years. During this geomagnetic storm, a disturbance occurred in a transformer in southern Sweden, causing a drop in power supply in the power line connecting Sweden and Poland.

Geomagnetic observatories: monitoring the Earth’s magnetic and space weather environment [PDF]

open access: yes, 2014
Geomagnetism research provides insight into the Earth’s properties and processes, from the core out to space. For this reason continuous geomagnetic field observations have been carried out in the UK for more than 170 years. Geomagnetism also has diverse

Low‐Frequency Polarization of Blank Ice Features in Solid Rocks

open access: yesGeophysical 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

open access: yesVadose 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.

Mapping a Carrington Storm

open access: yesGeophysical Research Letters
A map is presented of median 1‐min‐resolution peak geoelectric‐field strength across the United States as would be induced by magnetic storms as intense as the 2 September 1859 Carrington storm.

Three-dimensional geoelectric model of the Kirovograd ore area of the central part of the Ukrainian Shield

open access: yesГеофизический журнал, 2013
The authors give their 3D geoelectric model of the Kirovohrad ore district and consider aspects related to the association of uranium manifestations of albitite formation, gold fields and manifestations of graphite with anomalies of increased electrical

Electrodynamics of the middle atmosphere: Superpressure balloon program [PDF]

open access: yes
In this experiment a comprehensive set of electrical parameters were measured during eight long duration flights in the southern hemisphere stratosphere. These flight resulted in the largest data set ever collected from the stratosphere. The stratosphere

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

open access: yesJournal 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.

Long‐Term Peak Geoelectric Field Behavior for Space Weather Hazard Assessment in Alberta, Canada Using Geomagnetic and Magnetotelluric Measurements

open access: yesSpace Weather
To better understand the risks of space weather to electric power transmission networks, magnetometer data and nearby magnetotelluric impedance data at four sites in Alberta, Canada are used to estimate the induced geoelectric field over the last 12–32 ...
