Auditing marine survey evidence for submerged prehistoric landscapes on the Spanish Gulf of Cádiz shelf

This paper audits marine survey archives on the Spanish Gulf of Cádiz shelf to demonstrate that while existing data supports local palaeolandscape interpretation and exposed-object verification, it lacks the necessary metadata, geometry, and controlled outcomes to definitively rule out the presence of preserved prehistoric contexts across the region.

Seasonal Changes in Ocean Subsurface Structure Over the Arabian Sea and Their Association With Tropical Cyclone Characteristics

This study utilizes high-resolution HYCOM data to demonstrate that seasonal variations in the Arabian Sea's subsurface ocean structure—specifically mixed-layer depth, stratification, and heat content—drive distinct spatial patterns in tropical cyclone genesis, intensity, and track characteristics between the pre-monsoon and post-monsoon seasons.

From Riverine Transport to Legal Evidence: Coupled Hydrodynamic–Ecological Modelling of Transboundary Plastic Pollution

This study develops and validates a coupled hydrodynamic–ecological modeling framework that integrates field observations with discharge data to quantify transboundary plastic pollution fluxes, revealing that while upstream sources contribute significantly, locally introduced pollution dominates the annual export and demonstrating that boundary detection alone is insufficient for attributing contamination origins.

On the Link between the Saharan Heat Low and the Cameroonian Hydroclimate

This study utilizes ERA5 and CHIRPS data to demonstrate that the intensity of the Saharan Heat Low is a dominant driver of Cameroonian hydroclimatic variability, exhibiting a strong positive interannual correlation and a 3-to-8-day lagged response where extreme SHL deepening triggers regional precipitation surges while relaxation induces dry spells.

Probabilistic three-dimensional mineralogical characterisation of drill core using μXRF and XCT: application to the Nautanen North IOCG deposit

This study presents a probabilistic, deep learning-based framework that integrates 2D micro-XRF and 3D X-ray computed tomography data to generate accurate, uncertainty-aware three-dimensional mineralogical maps of drill cores, thereby enhancing geometallurgical characterization of the Nautanen North IOCG deposit.

Advancing Ecosystem Monitoring with Global High-Resolution Maps of Vegetation Biophysical Properties

The paper introduces S2BIOPHYS, a globally consistent 20 m resolution dataset of annual vegetation biophysical properties (LAIe, FAPAR, and FCOVER) for 2019–2025 derived from Sentinel-2 data via an optimized hybrid radiative transfer and neural network approach, which demonstrates high accuracy and supports diverse ecosystem monitoring applications.

Diagnosing double vulnerability in aging cities: A spatial coupling framework applied to elderly pedestrian crash risk and hospital accessibility in Seoul

This study develops a spatial coupling framework to diagnose "double vulnerability" in aging cities by integrating elderly pedestrian crash risk and hospital accessibility analysis in Seoul, identifying specific neighborhoods where high traffic danger and poor medical access converge to inform targeted urban governance interventions.
