Quantifying Thermo‐Fluid‐Chemical Coupling: Advection Governs Multi‐Phase Zonation and Self‐Sealing in a Hydrate‐Cold Seep System

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Deep fluid advection fundamentally governs the thermal‐fluid‐chemical evolution and distribution of hydrate‐cold seep systems. However, coupled relationships between deep fluid and shallow multiphase dynamics remain inadequately constrained.

How the 29 July 2025 M8.8 Kamchatka Earthquake Shook the Ionosphere Over Japan

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract This study investigates the mid‐field (∼1,100–3,800 km) ionospheric response to the 29 July 2025 Kamchatka earthquake over Japan using multi‐instrument observations, raytracing, and numerical simulations. Total electron content (TEC) observations from GPS satellite G04 and Galileo satellite E10 show a maximum TEC perturbation of ∼0.5–0.85 TECU

Quasi‐Periodic X‐Ray Variations at BARREL: Role of Electron Precipitation and Solar Wind Driving

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract The Balloon Array for Radiation belt Relativistic Electron Losses (BARREL) mission was designed to study the loss of radiation belt electrons to the upper atmosphere. Previous analysis of data from balloon pairs showed that electron precipitation events manifest coherent quasi‐periodic variations (with periodicity on the order of 10–60 min ...

Muon Flux Fluctuations and Solar Phenomena Using Regional Geomagnetic Indices With a Cosmic Ray Detector in Mexico City

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract The data from a cosmic ray (CR) detector in Mexico City were collected over a period of 2 years from September 2023 to September 2025, during the maximum phase of Solar Cycle 25. The CR detector consists of an array of scintillators and measures the muonic component of secondary CRs.

The Influence of Topography and Crustal Magnetic Anomalies on the Distribution of Water Ice in the Lunar South Pole Region

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract Lunar magnetic anomalies are abundant near the south pole, where several moderate‐strength anomalies spatially overlap permanently shadowed regions (PSRs). This environment provides a unique setting to assess how crustal magnetic fields and topography regulate plasma–surface interactions and, in turn, the stability and distribution of surface ...

A Principal Component Index for Identifying and Surveying Martian Chloride Salts Using THEMIS Multispectral Thermal Infrared Images

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract Martian chloride salt deposits were first identified by Osterloo et al. (2008, https://doi.org/10.1126/science.1150690) and surveyed by Osterloo et al. (2010, https://doi.org/10.1029/2010je003613) primarily using thermal infrared data acquired by the Thermal Emission Imaging System (THEMIS) onboard the 2001 Mars Odyssey spacecraft.

On optimisation of Paganin's method for propagation‐based X‐ray phase‐contrast imaging and tomography

Journal of Microscopy, Volume 303, Issue 1, Page 37-52, July 2026.
Abstract Paganin's method for image reconstruction in propagation‐based phase‐contrast X‐ray imaging and tomography has enjoyed broad acceptance in recent years, with over one thousand publications citing its use. The present paper discusses approaches to optimisation of the method with respect to simple image quality metrics, such as signal‐to‐noise ...

New knowledge about shock events that affected the L‐chondrite parent body from two heavily shocked L6 meteorite finds

Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1610-1626, July 2026.
Abstract We report new results from a study of shock‐related features in the L6 ordinary chondrites Northwest Africa (NWA) 4672 and NWA 12841. Our observations confirm the occurrence of eight high‐pressure (HP) minerals in each meteorite, namely, ringwoodite, majorite, akimotoite, wadsleyite, albitic jadeite, lingunite, tuite, and xieite.

Araguainha Dome, Brazil: A polygonal impact structure due to a complex pre‐impact regional structural framework

Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1355-1385, July 2026.
Abstract We investigated the structural framework of the north–northwestern Paraná Basin in Brazil to test whether the pre‐impact structures in this region may have had any influence on the first‐order formation and morphostructure of the Araguainha impact structure (AIS).
