Redefining SAR Arc Generation: The Competing Roles of Magnetospheric and Ionospheric Energy Injection

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Stable auroral red (SAR) arcs are luminous subauroral emissions produced by the collisional excitation of oxygen atoms during geomagnetically active times. While traditionally attributed to inner magnetospheric electron heating, recent observations and simulations challenge the exclusivity of this mechanism.

Twenty‐Five Years of Shifting Ground: Reflections on Publishing and Editing in the Earth Sciences

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract As the recipient of the 2024 William Kaula Award, I was asked to write an essay that captures stories and lessons learned during a career of scholarly editing. Over the past 25 years, I witnessed dramatic changes in scholarly publishing, from print‐dominated journals to open access, and increases in digital tools, and data‐sharing practices ...

Evidence for Subtropical Dynamical Changes in Reunion Ozone Trends (1998–2021)

Earth and Space Science, Volume 12, Issue 12, December 2025.
Abstract We provide trend estimates for total, stratospheric, and tropospheric ozone columns over Reunion (21.1°S, 55.5°E) from 1998 to 2021, using only Système d’Analyze par Observation Zénithale and Southern Hemisphere Additional OZonesonde observations.

Analysis of South Atlantic Anomaly Influence on Low‐Earth Orbit Lightning Observations

Earth and Space Science, Volume 12, Issue 12, December 2025.
Abstract The low‐Earth orbit Optical Transient Detector (OTD) and Lightning Imaging Sensor (LIS) instruments, spanning 1995–2023, have spatiotemporal patterns within their metadata that are consistent with the South Atlantic Anomaly (SAA). While the SAA had a known influence on these instruments, this study details new variability and impacts.

Role of Intersections in Fracture Connectivity

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Networks of intersecting fractures often provide the flow paths through subsurface reservoirs. Assessing network connectivity is challenging because fracture intersections compose a vanishingly small fraction of the network void volume. In this paper, motivated by 3D X‐ray imaging of the simplest element of fracture network, that is, two ...

The Influence of Space Weathering on the Far‐Ultraviolet Reflectance of Apollo‐Era Soils

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract Building on our previous studies of the far‐ultraviolet (FUV) reflectance of Apollo soil 10084 and lunar soil simulants JSC‐1A and LMS‐1 (Gimar et al., 2022, https://doi.org/10.1029/2022je007508; Raut et al., 2018, https://doi.org/10.1029/2018je005567), we present new FUV results for Apollo soils 68501 and 71061. Heavily weathered soils (68501,

The Orchestration and Harmonics of Biogeochemical Cycles in a Southeastern USA Saltmarsh

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.
Abstract Saltmarshes provide vital ecosystem services, including coastal protection and habitat for fisheries. While feedbacks influencing vertical sediment accretion in marshes are well‐documented, including those between relative sea level and primary production, relationships among nutrient cycles, flooding, and primary production remain less ...

Evolution of Terrestrial Planetary Bodies and Implications for Habitability

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract The terrestrial planetary bodies of our solar system—Mercury, Venus, Earth, and Mars—share a common origin through nebular accretion and early magma ocean differentiation, yet they diverged significantly in geological evolution, tectonic regimes, and habitability.
