This study evaluates five machine learning algorithms to predict soil organic carbon in Telangana's dry deciduous forests, identifying random forest as the most effective model and soil moisture as the most critical predictive variable.
This study utilizes hydrochemical, multivariate statistical, and geochemical modeling approaches to characterize the impact of acid mine drainage on groundwater in Santa Catarina's coal region, revealing significant contamination by metals like iron and manganese alongside evidence of natural neutralization processes and generally low toxicological risks.
This study identifies that high-frequency volcanic earthquakes at Ioto are predominantly similar events occurring near active faults and the Motoyama dome, which are driven by repetitive aseismic slip associated with crustal deformation and characterized by small fault radii and low stress drops indicative of reduced fault strength due to shallow volcanic fluids.
This paper proposes a self-consistent community reference model for trans-crustal magmatic systems to serve as a benchmark for integrating teleseismic, magnetotelluric, and petrological data, demonstrating that while individual methods have limited resolution, their combined use within a unified framework is essential for fully resolving the three-dimensional architecture of these systems.
While European climate extremes intensify unevenly across 1.5°C to 3.0°C global warming levels, this study finds that detrended interannual variability in the Atlantic Meridional Overturning Circulation (AMOC) shows no robust contemporaneous association with these extremes within comparable warming states.
By combining high-resolution microchemical mapping with in-situ geochronology in the Swiss Alps, this study demonstrates that fluid-driven mineral (re)equilibration, rather than strain accumulation or temperature, controls isotopic resetting during ductile deformation, thereby establishing fluid-mineral links as essential for accurately dating orogenic evolution.
This study utilizes synchrotron X-ray fluorescence to demonstrate that fossil elemental compositions are primarily driven by diagenetic processes and sediment interaction rather than original tissue chemistry, indicating that most detected elemental signatures are exogenous and that attempts to identify tissue-specific markers must strictly control for geologic formation.
This study investigates the oceanic response to Tropical Cyclone Seroja in the Savu Sea, revealing that the cyclone induced significant marine cold spells and Ekman pumping primarily driven by latent heat loss and turbulent mixing, following a period of high Tropical Cyclone Heat Potential that likely contributed to its intensification.
This study utilizes reproducible GIS analysis of public data to demonstrate that active hydrocarbon leases overlap significantly more with the Cook Inlet beluga whale's critical habitat than with Rice's whale's, while highlighting that the magnitude of overlap for Rice's whale is highly sensitive to the choice of habitat boundary used in the analysis.
This study assessed seasonal heavy metal contamination in the water resources of Nigeria's Riruwai mining area, finding that while concentrations were higher during the rainy season and exceeded regulatory limits in some samples, the associated non-cancer and cancer health risks for both adults and children remained within acceptable thresholds, though children were identified as more vulnerable.
