Quantitative Morphometry of the Ape Cave Lava Tube: A Statistical Framework for Terrestrial Analogue Studies of Planetary Subsurface Voids

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.
Abstract Recent discoveries suggest that intact lava tubes exist in the Moon and Mars, crucial for establishing long‐term habitable areas to protect future lunar and Martian dwellers from surface risks. Considering planetary lava tubes as potential natural shelters requires understanding their internal complexity, which is challenging due to the lack ...

Global Ionospheric Responses to Four X‐Class Solar Flares in November 2025

open access: yesSpace Weather, Volume 24, Issue 11, November 2026.
Abstract We investigate global ionospheric responses to four X‐class solar‐disk flares that occurred in November 2025 from the same solar active region, using multi‐instrument observations including GNSS, ionosonde, geomagnetic and GOES solar irradiance data. Pronounced dayside TEC enhancements are observed for three flares (#2 X1.2, #3 X5.1, and #4 X4.

Automatic Equatorial Ionospheric Irregularities Detection From GOLD Images Using Deep Learning

open access: yesSpace Weather, Volume 24, Issue 11, November 2026.
Abstract Accurate detection of Equatorial Ionization Anomaly (EIA) and Equatorial Plasma Bubble (EPB) is critical for understanding ionospheric dynamic characteristics and mitigating their adverse impacts on satellite‐based communication and navigation systems.

Deep Learning—Based Airglow Fusion and Forecasting for Equatorial Plasma Bubble Monitoring and GNSS Scintillation Prediction

open access: yesSpace Weather, Volume 24, Issue 11, November 2026.
Abstract Equatorial plasma bubbles (EPBs) are major low‐latitude ionospheric irregularities that can cause scintillation and degrade Global Navigation Satellite System (GNSS) performance. Existing amplitude‐scintillation prediction methods primarily use historical GNSS observations and ionospheric parameters, but rarely incorporate the evolving spatial

A validated 3D point‐cloud analysis workflow for the creation of seagrass canopy height models

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 11, Page 3136-3156, November 2026.
Abstract Seagrasses support highly productive ecosystems in both temperate and tropical waters and provide essential ecosystem services. Despite their importance, the vertical structure of seagrasses (i.e. the canopy) remains poorly characterised at the microscale, even though it is a strong predictor of ecological processes that influence both ...

Tectonic Re‐Organization and Onset of South Caspian Escape Tectonics at 1.8–2.4 Ma

open access: yesBasin Research, Volume 38, Issue 6, November‐December 2026.
We show that the presently active tectonics of the South Caspian began relatively recently, likely in the range 1.8–2.4 Myr and replacing an older tectonic configuration ending in the Miocene at ~6 Ma. The various short‐lived stages in the destruction of the South Caspian have potential for insight into the late stages of basin closure and the ...

Yield Losses due to Weed Competition in Synthetic Pesticide‐Free Cropping Systems With and Without Mineral Fertilizers

open access: yesWeed Research, Volume 66, Issue 6, November/December 2026.
ABSTRACT Consumers and policymakers call for crop production systems with less dependence on pesticides. In addition, national regulations require that fewer or no pesticides be used in specific protected areas, such as nature reserves or water protection areas.

Revealing the Hydrothermal System of La Soufrière Volcano (Guadeloupe) Through Nodal Ambient Noise Tomography

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract La Soufri'ere de Guadeloupe is an active volcano of the Lesser Antilles Volcanic Arc. Its last eruption halted in 1977, yet hydrothermal activity has increased over recent years, raising summit instability hazards. The link between hydrothermal fluids and detachment landslide surfaces is well established and exacerbated by inflation ...

Quantifying Nighttime Gravity Wave‐Driven Mesosphere‐Ionosphere Coupling Over CONUS Using NASA AWE Radiance and GNSS TEC Observations

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract We present the first coordinated study of nighttime mesosphere‐ionosphere coupling over the continental United States (CONUS) from January through November 2024 using NASA Atmospheric Waves Experiment (AWE) airglow measurements near 87 km and GNSS Total Electron Content observations near 300 km.
