Benchmarking Multiple Methods for the Spectral Analysis of Seafloor Morphology

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The influence of glacial sea‐level changes on the quasi‐periodic spacing of abyssal hills has remained controversial for over a decade. Spectral analyses of seafloor morphology have yielded contrasting conclusions regarding whether periodicities associated with orbital Milankovitch forcing are recorded in abyssal hill spacing, raising ...

Equatorial F‐Region Responses to the Main Phase of the 10 May 2024 Geomagnetic Storm Over the South American Sector: Observations and Model Simulations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract This study examines the equatorial ionospheric response over the South American sector during the onset of the extreme 2024 Mother's Day geomagnetic storm, which began at ∼17 UT on 10 May and reached the G5 level. Pronounced disturbances in ionospheric electrodynamics were observed under both daytime and nighttime conditions. Variations in the

Key Parameters for the Ionospheric Detection of Tsunamis From the 29 July 2025 Kamchatka Event

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract It has been demonstrated that tsunamis generate internal gravity waves (GWs) detectable in the ionosphere within 20–60 min after their generation at the ocean surface. Despite numerous simulation and observation studies on ionospheric signatures of tsunamis, the detection of Co‐tsunamic Ionospheric Disturbances (CTIDs) and distinguishing them ...

Nighttime Westward Equatorial Electrojet Observed During the January 2026 Geomagnetic Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract The equatorial electrojet (EEJ) is a narrow band of zonal electric current flowing in the E‐region ionosphere within approximately ±2° $\pm 2{}^{\circ}$ latitude of the magnetic equator. At night, the EEJ is generally considered very weak because of low ionospheric conductivity.

A Global Lithospheric Magnetic Field Model Derived From Multi‐Satellite Gradient Observations and Regional Aeromagnetic Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Using gradient data from the Macau Science Satellite‐1 (MSS‐1), CHAMP, Swarm‐A, and Swarm‐C satellites, together with aeromagnetic model data from China, we built the China‐specific Global Gradient Lithospheric Magnetic Model (CGGLM). The new model reaches spherical harmonic degree 140 and uses the Iteratively Re‐weighted Least‐Squares method ...
