GeoExtractor: A Framework for Structured Information Extraction from Geoscientific Literature

This paper introduces GeoExtractor, a large language model-powered multi-agent framework that employs a hierarchical extraction strategy to automatically convert unstructured geoscientific literature into structured data, significantly outperforming existing methods and successfully reconstructing known tectonic patterns from a compiled database of zircon analyses.

Marine Heatwave-Induced Stratification Promoted Subsurface Heat Storage and Supported the Rapid Intensification of Tropical Cyclone Winston

This study reveals that a marine heatwave-induced shallow mixed layer and enhanced stratification during Tropical Cyclone Winston (2016) facilitated the accumulation of subsurface heat, which was subsequently entrained by storm-induced mixing to sustain elevated energy fluxes and drive the cyclone's rapid intensification.

Vertical Structure and Evolution of Large-Scale Subsurface Marine Heatwaves

By applying a four-dimensional event-tracking framework to global ocean reanalysis data, this study characterizes the vertical structure and evolution of over 500 large-scale subsurface marine heatwaves, revealing seven distinct types driven by the interplay between large-scale climate variability (such as ENSO) and local ocean stratification.

Water Resource Conflict and Management Challenges in Post-Conflict Tribal Agricultural Communities: A Case Study of Waziristan, Pakistan

This study examines how post-conflict displacement and administrative changes in Waziristan have disrupted traditional water governance and infrastructure, leading to intensified resource conflicts, and proposes a hybrid framework integrating customary practices with state institutions to restore agricultural water security.

Reduced global atmospheric microplastic emissions from size-harmonized observations

By harmonizing observational and modeled microplastic particle size distributions, this study revises global atmospheric microplastic emissions downward to approximately 12 Gg yr⁻¹, revealing a 27-fold reduction from previous estimates and bridging the gap between top-down and bottom-up assessments.

Seismic intensity and potential damage generated by the 7.5 MW earthquake of March 20, 2012 in Mexico

This paper analyzes the 2012 Mw 7.5 Mexico earthquake to demonstrate that despite its high magnitude, the event caused only minor damage compared to the 1985 earthquake due to lower peak ground acceleration, shorter duration, and less destructive frequency content, thereby highlighting the critical importance of evaluating comprehensive seismic parameters beyond just magnitude for accurate risk assessment.
