Subseafloor Temperature Variability During Ridge‐Flank Hydrothermal Circulation: Implications for a Moderate‐Temperature Earth System and Other Ocean Worlds

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Subseafloor hydrothermal circulation drives biogeochemical exchange between the solid Earth and its ocean, and could play a similar role in other ocean worlds. We assess the scale of subseafloor temperature (T) variations during hydrothermal circulation in ∼3.5 Ma seafloor on the eastern flank of Juan de Fuca Ridge. This well‐studied, moderate

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

open access: yesJournal 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

Coordinate Systems and Transforms in Space Physics: Terms, Definitions, Implementations, and Recommendations for Reproducibility

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract In space physics, acronyms for coordinate systems (e.g., GEI, GSM) are commonly used; however, differences in their definitions and implementations can prevent reproducibility. In this work, we compare definitions in online resources, software packages, and frequently cited journal articles and show that implementation differences can lead to ...

Global Three‐Dimensional Simulation of Magnetospheric Dynamics During the Extreme Geomagnetic Storm of 10–11 May 2024

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract This study presents a high‐resolution three‐dimensional global magnetohydrodynamic (MHD) simulation of the historic geomagnetic storm of 10–11 May 2024, using observational data for the ACE solar wind input. This extreme event was characterized by intense solar wind dynamic pressure (∼50 nPa) and exceptionally strong interplanetary magnetic ...

Statistical Analysis of the Equatorward UV Auroral Emissions of the Jovian Southern Hemisphere

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract This study presents a comprehensive statistical analysis of Jupiter's southern UV auroral emissions, with a focus on the secondary oval and equatorward injection signatures. Utilizing Hubble Space Telescope (HST) data, the frequency, location, and intensity of these auroral features are systematically evaluated, considering their variation ...
