Beyond the Bulk: Magnetic Property Variations With Sediment Grain Size. Insights Into Process and Provenance

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract Bulk (whole sample) magnetic properties of three‐hundred‐sixty‐two samples from five North Atlantic Ocean sediment cores are compared to the magnetic properties of five grain‐size fractions separated from the same samples. The relative abundance and magnetic properties of the size fractions are highly variable both within a core and among ...

Magmatic and Tectonic Structures in the Crust Beneath Armenia and Surrounding Regions of Lesser Caucasus Inferred From Body‐Wave Earthquake Tomography

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract The Armenian Highlands, a tectonically active segment of the Arabia‐Eurasia collision zone, exhibit widespread Quaternary volcanism, rapid uplift, and intense seismicity. However, the lithospheric processes driving these phenomena remain poorly understood.

Voluminous Inflated Lobate Flows on the Distal Rift Zones of Axial Seamount, Juan de Fuca Spreading Ridge

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract Three voluminous inflated lobate lava flow complexes on the distal rifts of Axial Seamount are much larger than other known flows in the global spreading system. Each complex is 65–100 km2, is up to 130 m thick, and is ∼3.0–4.6 km3, almost 100 times the volumes of historical Axial flows.

Evolution of Ionospheric Ion Upflow Flux During the April 2023 Geomagnetic Storm

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract We study the impact of the evolving magnetosphere‐ionosphere‐thermosphere system on upward ion fluxes during the 23–24 April 2023 geomagnetic storm. This storm has a “double‐dip” structure where two southward IMF Bz ${\mathrm{B}}_{z}$ periods cause two dips in the SYM‐H index.
