Post-glacial carbon stocks in two restricted Patagonian fjord basins (52°S) using acoustic profiles and sediment cores

This study combines acoustic profiling and sediment core geochemistry to estimate full-column post-glacial carbon stocks in two restricted Patagonian fjord basins, revealing that total basin inventories are approximately two orders of magnitude larger than surficial estimates and include a substantial inorganic carbon component.

Multi-sensor geophysical observations resolve lahar dynamics remotely at Volcán de Fuego, Guatemala

By integrating seismic, infrasonic, and video observations, this study resolves the real-time dynamics of a rainfall-triggered lahar at Volcán de Fuego, revealing how channel morphology and a bedrock step modulate flow propagation, velocity, and sediment transport while demonstrating the efficacy of multi-sensor arrays for remote lahar monitoring.

Kuroshio-Oyashio Extension Sea Surface Temperature Variability as a Precursor for Winter California Precipitation

This study demonstrates that autumn sea surface temperature variability in the Kuroshio-Oyashio Extension region serves as an ENSO-independent precursor that significantly improves the seasonal prediction skill of winter California precipitation when combined with traditional ENSO indices.

Greywater Irrigation and Moringa-Derived Biochar in Contrasting Dryland Soil Materials: Salinity, Sodicity and Water-Retention Trade-offs

This study demonstrates that while Moringa-derived biochar enhances short-term moisture retention in Sudanese dryland soils irrigated with greywater, its sodium-rich chemistry introduces potential sodicity risks that necessitate a joint assessment of water, amendment, and soil properties before implementation.

Heavy Metal Contamination in Marine Fish from Turkish Seas: A Systematic Review of Spatial Patterns, Trophic Transfer, and Human Health Risks

This systematic review synthesizes data from 59 studies (2003–2025) on heavy metal contamination in Turkish marine fish, revealing significant regional variability in pollutant levels, generally acceptable but elevated risks for specific consumer groups, and the need for standardized monitoring to address emerging factors like microplastic interactions.

Multi-scale characterization of pore structure in deep coal and rock reservoirs and evaluation of movable fluids

This study integrates multiple characterization techniques to construct a continuous pore size distribution and establish a component-based prediction model for movable fluids in deep coal reservoirs, providing a rapid, non-destructive method for identifying "sweet spots" in the eastern Ordos Basin.

Ghost Roads as Hidden Drivers of Landscape Connectivity Loss in the Colombian Andes–Amazon Corridor

This study reveals that unmapped "ghost roads" in Colombia's Andean–Amazon corridor have expanded total road networks by over 300% since 2018, driving disproportionate habitat fragmentation and significantly increasing human impact beyond what official data suggests, thereby necessitating their inclusion in conservation planning.

Does the Morphological Evolution of Green Spaces Directly Influence Their Thermal Regulatory Capacity? Evidence from the Guangdong-Hong Kong-Macao Greater Bay Area

This study analyzes the morphological evolution and thermal regulatory capacity of green spaces in the Guangdong-Hong Kong-Macao Greater Bay Area, revealing that while green spaces have undergone fragmentation and a "decrease-then-increase" trajectory, specific morphological elements like Core, Perforation, and Edge significantly influence seasonal thermal patterns through complex linear and non-linear interactions.
