Using Natural Language Processing (NLP) to assess changes in transdisciplinary understandings across a large research consortium
Published: 2026-01-21
Subjects: Operations Research, Systems Engineering and Industrial Engineering
Researching how to create just and sustainable futures for all requires innovative and mission-oriented transdisciplinary approaches. This article sets out our approach and findings following the assessment, using Natural Language Processing (NLP), of the development in transdisciplinary understandings across a large and newly-forming research consortium as it changed over the six-year period of [...]
Estimation of Near-Surface Density using Vertical Gravity Gradients in Central and Western Japan
Published: 2026-01-22
Subjects: Earth Sciences
The Vertical Gravity Gradient (VGG), derived from the difference between terrestrial and airborne gravity data, highlights shallow density contrasts. We estimated the near-surface density structure of Central and Western Japan using VGGs derived from terrestrial data within 3 km of airborne flight lines. We constructed an inversion model on a 1/7-degree grid to estimate surface density and a [...]
Compounding effects of hurricanes and marine heat waves in the Gulf of America
Published: 2026-01-29
Subjects: Oceanography
Exposure to extreme events is a primary concern for coastal regions where growing populations and stressed ecosystems are increasingly vulnerable. This study assesses the compounding effects of hurricanes and marine heatwaves (MHWs) in the Gulf of America. Using data from 1982 to 2024, we quantify MHWs through metrics of intensity, frequency, duration, and spatial extent, and examine their [...]
Opportunities to integrate climate change adaptation and mitigation across strategic, adaptive and transformative pathways
Published: 2026-01-23
Subjects: Life Sciences, Social and Behavioral Sciences
Calls to integrate climate change adaptation and mitigation promote synergistic action. However, narrow, intervention- or sector-specific perspectives obscure complexities shaping how these agendas are operationalised in practice. This paper explores opportunities for integration from a systemic perspective, viewing climate resilient futures as emerging from diverse changes across sectors, [...]
A differential linear perturbation method for apparent I.P. calculations
Published: 2026-08-22
Subjects: Physical Sciences and Mathematics
3-D induced polarization (I.P.) surveys are widely used in exploration of minerals particularly those that contain conductive minerals sulfides that frequently occur in areas with complex geology. The linear perturbation method is frequently used to calculate the apparent resistivity and I.P. values. This method treats the I.P. effect as a linear change of a base conductivity model. The apparent [...]
Exploring Potential Mechanisms for the Initiation of Solifluction Patterns
Published: 2026-01-25
Subjects: Physical Sciences and Mathematics
Hillslopes in arctic regions commonly display large-scale features—known as solifluction patterns—that form due to the exceedingly slow downhill movement of frost-heaved soil. Here we use a combination of remote sensing data, linear stability analysis, numerical modeling, and review of a wide range of literature to evaluate several working hypotheses for the necessary and sufficient conditions [...]
PIKART Version 1.1: Release Notes
Published: 2026-06-12
Subjects: Physical Sciences and Mathematics
The PIK Atmospheric River Trajectories (PIKART) catalog is a global, high-resolution catalog of atmospheric rivers (ARs). Version 1.1 (v1.1) addresses two algorithmic bugs present in version 1.0 (v1.0): a boundary artifact at 30°E emerging during the extraction of the background component of the integrated vapor transport (IVT), and an error in the AR tracking algorithm that affected the [...]
Spontaneous liquefaction in saturated granular deposits: State controlled boundary and surface reconfiguration
Published: 2026-01-26
Subjects: Civil and Environmental Engineering, Civil Engineering, Earth Sciences, Engineering, Engineering Science and Materials, Environmental Engineering, Environmental Sciences, Geotechnical Engineering, Hydraulic Engineering, Mechanics of Materials, Mining Engineering, Other Civil and Environmental Engineering, Physical Sciences and Mathematics, Risk Analysis
In the case of water-saturated, granular deposits that are at risk of liquefaction, engineers need reliable information about the spatial extent of soil deformation in the event of liquefaction. It is not so important for them to know the exact location of the first failure. However, existing anal-yses primarily deal with the triggering of liquefaction and offer only limited information on how [...]
Pathways of resilience: a fuzzy-set Qualitative Comparative Analysis of healthcare systems resilience to extreme weather events
Published: 2026-01-26
Subjects: Medicine and Health Sciences
Background Increasing frequency and intensity of extreme weather events threaten healthcare services globally, with particularly intense risks to low-resource regions. Evidenced pathways for building and enacting resilience in complex health systems are under researched. Literature on resilient healthcare is dominated by infections disease outbreaks and lacks synthesised insights from [...]
A Quality-Control Procedure for Bio-Optical Applications of Hyperspectral Radiometric Upwelling Radiance and Downwelling Irradiance Profiles Measured by BioGeoChemical-Argo Floats.
Published: 2026-01-27
Subjects: Climate, Oceanography, Oceanography and Atmospheric Sciences and Meteorology, Other Oceanography and Atmospheric Sciences and Meteorology
Autonomous in-situ radiometric observations are increasingly used to constrain bio-optical processes and validate satellite ocean-color products, such as remote sensing reflectance and diffuse attenuation coefficients. Because these observations are collected independently of weather and sea-state conditions, their application critically depends on robust quality control. Starting in 2012, the [...]
Near-total loss of buttressing stresses observed on Pine Island Ice Shelf, West Antarctica
Published: 2026-01-27
Subjects: Earth Sciences, Glaciology, Physical Sciences and Mathematics
Ice shelves, the floating extensions of the Antarctic Ice Sheet, provide critical buttressing stresses that resist the seaward flow of ice and help set the position of the grounding line, where the ice goes afloat. As buttressing stresses are diminished by thinning or fracturing and collapse of the ice shelf, glaciers tend to accelerate. Here, we focus on the response of Pine Island Ice Shelf [...]
Exploring the compositional variability of magmas erupted at La Soufrière volcano, St Vincent, using chemostratigraphy and new 40Ar/39Ar ages
Published: 2026-01-27
Subjects: Education
The temporal compositional variation of individual volcanic centres is key to understanding magmatic processes in the underlying crust. La Soufrière volcano, St. Vincent, Lesser Antilles, has erupted predominantly basaltic andesite magmas for hundreds of thousands of years. Sampling of the recently exposed crater walls at La Soufrière reveals that sequentially emplaced crater lavas, feeder dykes, [...]

Published: 2026-01-28
Subjects: Geophysics and Seismology
We present INTEGRATE, a Python package for fast localized probabilistic inversion of geophysical data. The framework provides a general approach for Bayesian inference in localized inverse problems, where the same prior information applies to many independent datasets. INTEGRATE implements an extended rejection sampling algorithm with temperature annealing for efficient posterior sampling. The [...]
Enhancing the Generalization of Flood Susceptibility Models: A Leakage-Aware Ensemble Framework for Deltaic Landscapes
Published: 2026-05-08
Subjects: Civil and Environmental Engineering, Engineering, Environmental Engineering, Hydraulic Engineering
Flood susceptibility mapping (FSM) is a cornerstone of disaster risk reduction in low-lying deltaic regions; however, conventional machine learning (ML) applications frequently suffer from spatial data leakage, resulting in inflated performance metrics and unreliable hazard predictions. To address this critical methodological shortcoming, this study develops a robust, leakage-aware ML framework [...]
