Robustness of characteristics of the Matuyama-Brunhes geomagnetic field reversal found in global models

Frontiers in Earth Science
Paleomagnetic data enables the global reconstruction of the geomagnetic field, allowing the investigation of significant events like polarity reversals and excursions.

Estimating the extremes in European geomagnetic activity [PDF]

, 2009
Rapidly changing geomagnetic field variations constitute a natural hazard, for example in navigation and, through geomagnetically induced currents, to power grids and pipeline networks.

Detection of Equatorial Plasma Bubbles Using the COSMIC‐2 Rate of TEC Index

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Equatorial plasma bubbles (EPBs) are large‐scale plasma depletion structures that can disrupt Global Navigation Satellite Systems (GNSS) and other space‐based technologies. Several instruments have been employed to study EPB dynamics, with Total Electron Content (TEC) and Rate of TEC change Index (ROTI) data standing out as valuable parameters

A Compensation Method for the Geomagnetic Measurement Error of an Underwater Ship-Borne Magnetometer Based on Constrained Total Least Squares

Sensors
When magnetic matching aided navigation is applied to an underwater vehicle, the magnetometer must be installed inside the vehicle, considering the navigation safety and concealment of the underwater vehicle.

Effect of Field Line Torsion on the Polarization of ULF Waves

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract In this paper we suggest a simple modification of the dipole magnetic field which introduces field‐aligned currents and torsion to the field lines. The resulting field lines are not contained in the meridional planes and have resemblance to the geomagnetic field lines in the dawn and dusk flanks of the magnetosphere. We analyze polarization of

A Hierarchical Bayesian Model for the Global Holocene Geomagnetic Field

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract We present a hierarchical Bayesian model of the global geomagnetic field for the last 8,000 years. The model is built solely with thermoremanent records, which include archeomagnetic and volcanic data. Building upon previous work, this model includes fewer approximations and treats model hyperparameters as probabilistic variables.
