Earth and Space Science, Volume 13, Issue 1, January 2026.Abstract Oxychlorines (i.e., perchlorates (ClO4−) and chlorates (ClO3−)) have been detected by several landed missions on Mars at various locations. These missions have provided crucial information about the geographic distribution and abundances of oxychlorines on Mars but have not definitively identified the cation and anion type of in situ, solid ...

Earth and Space Science, Volume 13, Issue 1, January 2026.Abstract Context. The Electron Proton Helium INstrument (EPHIN) aboard SOlar and Heliospheric Observatory is a particle telescope that measures energetic protons and helium above 4 MeV/nuc and electrons above 150 keV. While a calibration of EPHIN has been performed before launch, it has only partially been assessed reducing the accuracy of the detector

Enhanced Radiation Exposure of Airline Crew and Passengers During the May 2024 Geomagnetic Storm
Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract Enhanced radiation at aviation altitudes is a concern for flight crew and passengers. During space weather events, solar flares and coronal mass ejection (CME) driven shocks are sources of energetic particles that can reach Earth's near‐space environment and interact with its magnetic field and atmosphere.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract Equatorial plasma bubbles (EPBs) pose significant challenges to trans‐ionospheric radio communication and navigation systems. Because of their disruptive effects, evaluating and predicting them is key for the development of space systems. The influence of geomagnetic activity on EPBs remains unclear, partly due to limited low‐latitude neutral ...

An Extended Amplitude Range Readout Circuit for Charged Particle Detection–BEAR 2
Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract Charge sensitive amplifiers (CSA) form the first stage of most detector readout circuits. The operating range of the readout circuits depends on the saturation limits of the Charge sensitive amplifiers, thereby limiting the range of the detector system as well. A number of methods have been introduced to extend the dynamic range of the readout

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.Abstract The 2021 eruption of Cumbre Vieja on La Palma, Canary Islands, provided a unique opportunity to investigate the dynamics of magma migration and storage during a large effusive eruption. In this study, we employ repeated seismic tomography to image temporal changes in the subsurface structure beneath La Palma, using body‐wave travel times from ...

Geomagnetic Variability in a Post‐Superchron Geodynamo: Insights From the Deccan Traps
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.Abstract Studying long‐term geomagnetic field behavior is crucial for understanding Earth's evolution, as field variability reflects processes in the planet's deep interior. One key question concerns the relationship between field strength and polarity reversal frequency, particularly during the Cretaceous Normal Superchron (CNS), a prolonged interval ...

Deep Water Renewal in the Amerasian Basin Derived From Natural and Anthropogenic Tracer Data Sets
Journal of Geophysical Research: Oceans, Volume 131, Issue 1, January 2026.Abstract The deep waters of the Amerasian Basin in the Arctic Ocean are among the most isolated in the modern Arctic Mediterranean Sea (e.g., Schlosser et al., 1997, https://doi.org/10.1016/s0168‐583x(96)00677‐5). In this study, we use a suite of tracers spanning a range of timescales—including chlorofluorocarbons (CFCs), SF6, radiocarbon (14C), and ...

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.Abstract Analysis of space weathering features in lunar regolith using transmission electron microscopy (TEM) allows researchers to characterize the surface exposure timescale of individual grains from the Moon. TEM analysis of regolith grains from Apollo 17 scoop samples, collected from five different locations in the Taurus‐Littrow Valley (TLV), each
