Subjects: Climate, Oceanography, Oceanography and Atmospheric Sciences and Meteorology, Other Oceanography and Atmospheric Sciences and Meteorology
Autonomous in-situ radiometric observations are increasingly used to constrain bio-optical processes and validate satellite ocean-color products, such as remote sensing reflectance and diffuse attenuation coefficients. Because these observations are collected independently of weather and sea-state conditions, their application critically depends on robust quality control. Starting in 2012, the [...]
Near-total loss of buttressing stresses observed on Pine Island Ice Shelf, West Antarctica
Published: 2026-01-27
Subjects: Earth Sciences, Glaciology, Physical Sciences and Mathematics
Ice shelves, the floating extensions of the Antarctic Ice Sheet, provide critical buttressing stresses that resist the seaward flow of ice and help set the position of the grounding line, where the ice goes afloat. As buttressing stresses are diminished by thinning or fracturing and collapse of the ice shelf, glaciers tend to accelerate. Here, we focus on the response of Pine Island Ice Shelf [...]

The temporal compositional variation of individual volcanic centres is key to understanding magmatic processes in the underlying crust. La Soufrière volcano, St. Vincent, Lesser Antilles, has erupted predominantly basaltic andesite magmas for hundreds of thousands of years. Sampling of the recently exposed crater walls at La Soufrière reveals that sequentially emplaced crater lavas, feeder dykes, [...]
Stadiums as climate-exposed socio-technical infrastructures: a scoping review of fragmented risks and emerging challenges
Published: 2026-01-28
Subjects: Civil and Environmental Engineering, Environmental Public Health, Environmental Studies
Stadiums are among the most climate-sensitive infrastructures in global sport, yet the evidence available to characterise their climate-related risks remains fragmented. Although billions of spectators attend sporting events each year and climate change is recognised as a multiplier of existing hazards, research on stadium environments continues to treat risks separately. Heat is examined through [...]

Enhancing the Generalization of Flood Susceptibility Models: A Leakage-Aware Ensemble Framework for Deltaic Landscapes
Published: 2026-05-08
Subjects: Civil and Environmental Engineering, Engineering, Environmental Engineering, Hydraulic Engineering
Flood susceptibility mapping (FSM) is a cornerstone of disaster risk reduction in low-lying deltaic regions; however, conventional machine learning (ML) applications frequently suffer from spatial data leakage, resulting in inflated performance metrics and unreliable hazard predictions. To address this critical methodological shortcoming, this study develops a robust, leakage-aware ML framework [...]
Do 3D Dynamic Rupture Models Capture the Variability in Long-Period Velocity Pulses? Insights from the 2023 Mw 7.8 Kahramanmaraş Earthquake
Published: 2026-01-28
Subjects: Physical Sciences and Mathematics
Capturing ground motion variability, especially in near-fault long-period velocity pulses, is a key challenge for seismic hazard assessment. Empirical methods often rely on simplified assumptions and may not fully capture the non-linear interplay of source, path, and site effects. Physics-based dynamic rupture simulations offer a self-consistent alternative, but their ability to reproduce [...]
