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
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
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.

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
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
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 ...

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.

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 ...
