AI-Assisted Educational Framework for Floodplain Manager Certification: Enhancing Vocational Education and Training Through Personalized Learning
Published: 2024-11-26
Subjects: Education, Engineering
Floodplain management is critical for mitigating flood risks and safeguarding communities. The FloodPlain Manager (FPM) certification is essential for professionals in this field, but current preparation methods often fall short in providing comprehensive, accessible, and engaging study resources. This research introduces a novel AI-assisted educational tool designed specifically for FPM [...]
VolcAshDB – A global database of volcanic ash particles
Published: 2024-11-25
Subjects: Geology, Volcanology
Volcanic ash is made of particles smaller than 2 mm and is produced during volcanic eruptions. Studying the properties of volcanic ash is key for a range of applications, including volcano monitoring. However, given the large variety of textures, colors, and shapes of particles from different eruptions and volcanoes it is challenging to classify them in a reproducible and systematic manner. Here, [...]

Evidence for large disturbances of the Ediacaran geomagnetic field from West Africa
Published: 2024-11-27
Subjects: Earth Sciences, Geophysics and Seismology, Physical Sciences and Mathematics, Tectonics and Structure
Constraining the paleogeography of the Ediacaran is crucial for understanding the extensive tectonic, biological and geochemical changes that occurred during that epoch. Paleomagnetism is an essential tool for reconstructing the Ediacaran paleogeography but it is complicated because the paleomagnetic data of that age display unusually fast and large directional oscillations. Two main competing [...]
Integration and Execution of Community Land Model Urban (CLMU) in a Containerized Environment
Published: 2024-11-27
Subjects: Civil Engineering, Computer Sciences, Earth Sciences, Environmental Engineering, Environmental Sciences
The Community Land Model Urban (CLMU) is a process-based numerical urban climate model that simulates the interactions between the atmosphere and urban surfaces, serving as a powerful tool for the convergence of urban and climate science research. Despite its advanced capabilities, CLMU presents significant challenges for users unfamiliar with numerical modeling due to the complexities of model [...]
XAI and Sustainability: Unifying Regulatory Standards and Solutions for the Future of Environmental Management

Subjects: Social and Behavioral Sciences
This study explores the integration of Explainable Artificial Intelligence (XAI) into environmental governance, addressing critical challenges in transparency, public trust and regulatory compliance. As AI technologies increasingly influence decision-making in environmental management, ensuring equitable and ethical practices has become paramount. By examining key regulatory frameworks, including [...]
Empirical evidence of dynamic hydrogeomorphic feature inundation in a lowland floodplain
Published: 2024-11-27
Subjects: Physical Sciences and Mathematics
Floodplains along low-gradient, meandering river systems contain diverse hydrogeomorphic features, ranging from isolated depressions to hydrologically-connected channels. These ephemerally-flooded features inundate prior to river water overtopping all banks, enhancing river-floodplain connectivity during moderately high flow stages. Predicting when and where ecological functions occur in [...]
Bioenergetic modeling reveals opposing effects of ocean and terrestrial warming of an intertidal crustacean
Published: 2024-11-28
Subjects: Ecology and Evolutionary Biology
Organism-level bioenergetics models (OBMs) are an emerging tool for predicting consequences of climate change on organism growth in ecological systems. Global changes in ocean and atmospheric temperature may affect organisms that experience both environments, such as those living in intertidal systems. The acorn barnacle, Balanus glandula, is prevalent throughout the intertidal zone in the [...]
Deep Learning-Based Satellite Image Analysis for Predicting Land Surface Temperature and Emissivity from Multi-Region Landsat 8 OLI/TIRS Imagery
Published: 2024-11-28
Subjects: Signal Processing
This research investigates the efficacy of deep learning techniques in estimating Land Surface Temperature (LST) and Emissivity from Landsat satellite imagery across seven distinct geographical regions. Utilizing the Single Channel Method for LST estimation and an NDVI-based approach for Emissivity estimation, our study spans the years 2018 to 2023, ensuring data integrity with cloud cover below [...]
Insights into upper lithosphere detachment and exhumation through numerical modelling
Published: 2024-11-28
Subjects: Physical Sciences and Mathematics
The mechanisms underlying exhumation have been a topic of debate among researchers for many decades, prompting the development of numerous computational models aimed at elucidating the processes that initiate exhumation. However, a key gap in the literature lies in understanding how segments of the subducting lithospheric plate detach and subsequently exhumate after extended periods. [...]

Human health impacts of PFAS exposure: A second-order meta-analysis
Published: 2026-10-04
Subjects: Environmental Public Health, Public Health
Per- and polyfluoroalkyl substances (PFAS) are highly persistent synthetic chemicals with pervasive human exposure. Numerous meta-analyses have synthesised results on the association between PFAS exposure and human health, yet findings remain fragmented and often inconsistent across compounds, outcomes, and studies. We assessed the magnitude and consistency of associations between PFAS exposure [...]
