Effective permeability of fluvial lithofacies in the Bunter Sandstone Formation, UK
Published: 2024-11-29
Subjects: Oil, Gas, and Energy, Sedimentology, Water Resource Management
Understanding effective permeability is crucial for predicting fluid migration and trapping in subsurface reservoirs. The Bunter Sandstone of North-West Europe hosts major groundwater and geothermal resources and is targeted for CO2 and hydrogen storage projects. Here the effective permeability of fluvial facies within the Bunter Sandstone Formation was assessed using facies-scale models. Twelve [...]
The State of Global Catastrophic Risk Research: A Bibliometric Review
Published: 2024-11-29
Subjects: Agriculture, Biodiversity, Environmental Sciences, Environmental Studies, Food Science, Geography, Other Life Sciences
The global catastrophic risk (GCR) and existential risk (ER) literature focuses on analysing and preventing potential major global catastrophes including a human extinction event. Over the past two decades, the field of GCR/ER research has grown considerably. However, there has been little meta-research on the field itself. How large has this body of literature become? What topics does it cover? [...]
Oceanic Alkalinity and Titration Alkalinity: a novel straightforward approach in keeping with common general chemistry
Published: 2024-11-29
Subjects: Oceanography and Atmospheric Sciences and Meteorology
We present novel exact concepts of Oceanic Alkalinity and Titration Alkalinity that are in keeping with common chemistry. Oceanic Alkalinity is the small difference of the sum of charges of strong cations and the sum of charges of strong anions in seawater. This difference is compensated by the sum of charges of the weak anions minus the sum of charges of the weak cations. Titration Alkalinity [...]

Efficient Carbon Dioxide and Methane Flux Monitoring in Soil Microcosms Using an Automated Chamber with a Cartesian Robot
Published: 2024-11-29
Subjects: Civil and Environmental Engineering, Environmental Engineering, Environmental Monitoring, Environmental Sciences, Physical Sciences and Mathematics
1.Accurate measurement of carbon dioxide (CO₂) and methane (CH₄) emissions from soil is crucial for understanding carbon dynamics and developing strategies to mitigate climate change. Traditional chamber techniques and soil incubation experiments each have limitations that hinder their efficiency and accuracy. This study aims to overcome these challenges by integrating automated technologies [...]
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. [...]
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 [...]
Carbon dioxide removal could perpetuate community-scale inequalities of U.S. air pollution in net-zero scenarios
Published: 2024-11-27
Subjects: Environmental Public Health, Environmental Sciences, Environmental Studies
Pathways to net-zero reduce GHG emissions and improve air quality, but the magnitude and distribution of these improvements will depend on specific mitigation decisions, such as the amount of carbon dioxide removals (CDR). Here, we combine a series of models and datasets to analyze community-scale PM2.5 impacts across the contiguous U.S. of net-zero scenarios with different levels of CDR. Both [...]
Deep Learning-Based Satellite Image Analysis for Predicting Land Surface Temperature and Emissivity from Multi-Region Landsat 8 OLI/TIRS Imagery
Published: 2024-11-27
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 [...]
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 [...]

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 [...]
Evidence for large disturbances of the Ediacaran geomagnetic field from West Africa
Published: 2024-11-26
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 [...]
Multiregional accounting of corporate carbon emissions
Published: 2024-11-26
Subjects: Environmental Monitoring, Environmental Sciences, Natural Resources and Conservation, Physical Sciences and Mathematics, Sustainability
Corporations routinely use environmentally-extended input-output models to estimate and report greenhouse gas emissions upstream in their supply chain. However, the most widely used of such models assume that the structure of supply chains and the emissions intensity of industries match those of a single region—usually the U.S. or the U.K. Here, we use a high-resolution multiregional input-output [...]
