Determining Magnetic Field Intensity and Direction From the Anisotropy of Magnetic Remanence in Sediments

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract Anisotropy of magnetic remanence (AMR) holds promise for quantifying relative paleointensity values from sedimentary rocks. A proof of concept was established for applied fields that exceeded the intensity of the geomagnetic field. Under Earth‐like fields, large uncertainties necessitate the development of a new approach to improve the ...

Late Eocene to Early Oligocene (36–26 Ma) Rock Magnetism and Magnetostratigraphy of IODP Site U1553, Southwestern Pacific: Defying the Challenges of Carbonate Dilution and Reductive Diagenesis

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract The late Eocene to early Oligocene is an intriguing Paleogene period in which the Earth climate state changed from Warmhouse to Coolhouse. Accurate age models are essential for investigating these climate transitions. The southwestern Pacific International Ocean Discovery Program (IODP) Site U1553, with its almost complete succession of the ...

Global Ionospheric TEC Variability: Long‐Term Spectral–Wavelet Analysis and Geomagnetic Storm Event Case Studies

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract This study investigates global ionospheric variability using Global Total Electron Content (GTEC), defined as the spatial average of daily averaged Global Ionospheric Maps derived from the International GNSS Service. The analysis spans from 2010 to 2024, covering Solar Cycle 24 and the rising phase of Solar Cycle 25, and incorporates ...

Reversals and Excursions of the Geomagnetic Field as Defined by Palaeomagnetic Data from Upper Palaeozoic-Lower Mesozoic Sediments and Igneous Rocks from Argentina

open access: yesJournal of geomagnetism and geoelectricity, 1980
Palaeomagnetic data from samples collected in rock sequences of sediments and igneous rocks of Late Palaeozoic and Triassic age exposed in northwestern Argentina are summarized. On basis of these data a composite magnetic stratigraphy for the Late Carboniferous, Permian and Early and Middle Triassic was prepared.They record two normal polarity events ...

Matlab code for "Geomagnetic reversals and excursions as an outcome of non-equilibrium wave-turbulence and beating MAC waves in the core"

open access: yes
The MATLAB code which allowed to produce energy plots for energy of the magnetic field generated by a non-stationary MAC-wave field in the Earth's core (for the paper entitled: "Geomagnetic reversals and excursions as an outcome of non-equilibrium wave-turbulence and beating MAC waves in the core")
