Published: 2026-08-23
Subjects: Applied Statistics, Environmental Indicators and Impact Assessment, Geology, Mining Engineering, Multivariate Analysis, Risk Analysis, Sustainability
As Sicily expands its renewable energy portfolio, the need for large-scale energy storage becomes increasingly urgent to ensure supply-demand balance. Hydrogen storage in salt caverns represents a promising solution in this context. This study presents the first real-world application of the Common Risk Segment (CRS) methodology, originally developed for oil and gas exploration and recently [...]
Upper Crustal Control on Nearshore Subduction Mechanics in Cascadia
Published: 2026-04-24
Subjects: Geology, Geophysics and Seismology, Tectonics and Structure
Along-strike upper plate heterogeneity is widely observed at subduction margins, but its direct influence on slab geometry and interseismic deformation remains debated. Here, we investigate the effect of upper-crustal geological segmentation on nearshore subduction mechanics at the Cascadia margin. Using a high-resolution, shore-crossing 3-D seismic tomography model from central to southern [...]
Canada's Landfill Methane Inventories: The Challenge of Accurate Modeled and Measurement-Based Emissions
Published: 2025-11-15
Subjects: Earth Sciences
We present a measurement-based assessment of methane emissions from 42 landfills across diverse climatic regions in Canada. Our findings reveal that emission rates predicted by the First Order Decay (FOD) model used by Environment and Climate Change Canada at the visited sites are substantially higher than most measured emission rates, on average by a factor of 3, particularly for cold and arid [...]
Arctic summer cloud optical properties and annual sea-ice retreat
Published: 2026-03-07
Subjects: Earth Sciences, Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics
Changes in Arctic sea-ice areal coverage have major ecological, climate, and economic implications and are driven by diverse natural and anthropogenic forcings acting over a wide range of time scales. Cloud-related variability in atmospheric radiative budgets is suspected to be particularly important in year-to-year changes in ice melt. Here, we describe a decade of pan-Arctic satellite light [...]
A 3-D Hybrid SEM-FK Method for Teleseismic Wave Simulation in Coupled Elastic-Acoustic Media
Published: 2026-02-15
Subjects: Geophysics and Seismology, Physical Sciences and Mathematics
We present a three-dimensional hybrid numerical scheme developed for modeling teleseismic plane-wave propagation through coupled acoustic–elastic media. This approach integrates the 3-D spectral-element method (SEM) with a matrix-based frequency–wavenumber (FK) method, enabling the rigorous treatment of complex bathymetry and precise elastic–acoustic coupling within layered media. To facilitate [...]
Time-dependent forecast of large earthquakes from physics-informed probabilistic approach
Published: 2026-03-07
Subjects: Earth Sciences, Geophysics and Seismology, Physical Sciences and Mathematics
The elastic energy that fuels large earthquakes accumulates heterogeneously along faults, resulting in complex earthquake occurrence patterns. Although earthquake cycle simulations help capture such complexity in seismic hazard models, their high computational cost prevents widespread use and uncertainty quantification. Here, we propose a physics-based probabilistic method to forecast the timing [...]
Paragliders as probes of the Alpine boundary layer: sink polars from 86 000 flight logs and the flow field of a valley
Published: 2026-10-15
Subjects: Atmospheric Sciences, Fluid Dynamics, Meteorology, Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics, Physics
Paraglider flight logs are a dense, free and continuous record of the air over mountains: every thermal day, hundreds of pilots fly for hours along the slopes and across the valleys and record their vertical speed once per second. The obstacle is that a vario measures the air plus the sink of the glider, and the sink polars of paragliders are unknown. We obtain them from the logs themselves. [...]
Biotite/melt trace-element, lithium, and F-OH partitioning in silicate magmas
Published: 2026-02-17
Subjects: Earth Sciences, Geochemistry, Inorganic Chemistry, Materials Chemistry, Other Earth Sciences
Biotite is a key hydrous silicate mineral in evolved magmatic systems, but its control on the behaviour of minor- and trace-elements, in particular Li, Nb, F and the REE is not well understood. Here, we quantify that control in sodic (per)alkaline H2O-saturated magmas with variable F-content through crystallisation experiments at 650–800◦C and 200 MPa total pressure, at log f O2 ≈ FMQ +1. [...]
System openness governs detectable signals of enhanced rock weathering in soils: a global meta-analysis
Published: 2026-08-28
Subjects: Physical Sciences and Mathematics
Substantial heterogeneity in enhanced rock weathering (ERW) outcomes is often attributed to dissolution controls. However, we show that experimental boundary conditions – especially system openness – provide a primary explanation because dissolution products can be redistributed or exported beyond the sampled pool. We synthesise 81 peer-reviewed ERW studies (205 comparisons) using [...]
Along-strike coupling heterogeneity in Cascadia’s slow-slip zone constrained by GNSS and reduced-order rate-and-state friction modeling
Published: 2026-03-07
Subjects: Earth Sciences, Geophysics and Seismology
Slow slip events (SSEs) in the Cascadia subduction zone exhibit along-strike segmentation, where the central segment has longer recurrence intervals but smaller moments. We quantify the controls on this variability by combining geodetic inter-SSE coupling inversion with Bayesian inference of a quasi-dynamic rate-and-state friction SSE-cycle model accelerated by reduced-order modeling. Our [...]
Author citation metrics in paleontology: the h-index and the c-score
Published: 2025-10-07
Subjects: Paleontology
The “Stanford ranking” (SR) of standardized citation indicators calculates an individual scientist’s composite c-score, addressing limitations of the h-index. Updated annually, the SR lists the top 100,000 scientists and the top 2% in each specialty. This study examines all (500) palaeontologists included in the SR (SR-palaeontologists), comparing their h-index, c-score and related productivity [...]

Published: 2026-04-17
Subjects: Life Sciences, Physical Sciences and Mathematics
India’s rapid economic growth regularly jeopardizes its environmental foundation, although important sub-national differences were typically hidden by national-level evaluations. For all 37 Indian states and union territories (UTs), this study creates the Composite index of Environmental Sustainability (CoES), a comprehensive multi-dimensional framework that integrates 36 indicators across 4 [...]
Spatial-Temporal Assessment of Natural Disaster Losses Using Comb- ined AHP-Entropy Weight Method: A Case Study of Jiangxi Province
Published: 2026-03-29
Subjects: Risk Analysis
The Disaster Situation Index (DSI) serves as a crucial method for natural disaster loss assessment. However, the weight determination in existing assessment practices is characterized by strong subjectivity and methodological singularity, while the classification of DSI also suffers from artificial subjective arbitrariness. To resolve these two issues, this study proposes a hybrid approach [...]
A benchmark deep learning dataset for the classification of supraglacial lake drainage mechanism across the central-west Greenland Ice Sheet
Published: 2026-05-29
Subjects: Artificial Intelligence and Robotics, Earth Sciences, Glaciology, Numerical Analysis and Scientific Computing, Physical Sciences and Mathematics
Supraglacial lakes on the Greenland Ice Sheet drain through physically distinct pathways: hydrofracture, moulins, lateral stream routing, and crevasse-fields. Each drainage mechanism carries unique implications for ice sheet dynamics. Existing automated classifications reduce each lake's drainage behavior to a time-series of scalar values representing the observed water surface-area and classify [...]
