Characterizing the interrelationships of commonly used water measures
Published: 2026-03-18
Subjects: Public Health
There are numerous commonly used measures of household water access that capture various dimensions of the household water experience, but it is unclear if individual variables are complementary, redundant, or uniquely informative. We characterized how measures of household water access are statistically and conceptually interrelated. Using data collected from 861 households in Beira, Mozambique [...]
A Systematic Review of Toxic Metals Occurrences through Drinking Water in Ghana
Published: 2026-03-18
Subjects: Environmental Sciences
Toxic metals (TMs) are metallic contaminants that cause adverse health effects even at low exposure levels. Arsenic (As), Manganese (Mn), Lead (Pb), and Cadmium (Cd) are among these contaminants of concern, causing irreversible developmental damage to children (Pb), as well as cardiovascular disease (Pb) and cancers (As) in adults. Arsenic and Manganese are primarily geogenic groundwater [...]
Temporal Analysis of Site-Level Methane Emissions from Nearly One Thousand Upstream Oil and Gas Facilities Equipped with Fixed-Point Continuous Monitoring Systems
Published: 2026-03-18
Subjects: Environmental Sciences, Physical Sciences and Mathematics
Temporal variability in methane emissions from oil and gas facilities may significantly impact the accuracy of measurement-based emissions inventories and the effectiveness of measurement-based mitigation policies. Yet the existing knowledge of duration, frequency, and magnitude of emission events remains very limited. A deeper understanding of these temporal characteristics is therefore [...]
Transient liquid- and solid-dominated inflation of an upper crustal magma chamber: insights from the Carlingford Complex (Ireland)
Published: 2026-03-18
Subjects: Earth Sciences, Geochemistry, Geology, Volcanology
Layered intrusions are the crystallised remnants of magma reservoirs and preserve a detailed record of magma storage, differentiation, and recharge processes in the upper crust. Their assembly is commonly categorised into two end-member emplacement regimes: long-lived liquid-dominated magma chambers, and incrementally assembled crystal-rich mush systems. These end-members are often presented as [...]
Comparison of probabilistic approaches to acoustic full-waveform inversion in compressed model and data spaces
Published: 2026-03-18
Subjects: Physical Sciences and Mathematics
Full-waveform inversion estimates subsurface properties by minimizing the misfit between observed and modelled data. However, conventional deterministic approaches are highly sensitive to noise, dependent on the starting model and prone to converging to local minima of the cost function. Bayesian approaches offer a viable alternative, enhancing solution space exploration and providing uncertainty [...]
Agentic Modelling Pipeline: Reproducible Rapid Stormwater Modelling Management System with OpenClaw
Published: 2026-03-17
Subjects: Civil and Environmental Engineering, Civil Engineering, Computational Engineering, Engineering, Environmental Engineering, Hydraulic Engineering
Configuring urban hydrological models, such as SWMM, for operational or real-time modelling remains onerous for many models. We propose an Agentic SWMM workflow, which embeds ‘Skills’ and model context protocols to automate model configuration, execution, and extract and plot quantities of interest. To ensure that the entire Agentic SWMM workflow is auditable and reproducible, each run will [...]
WetlandMapper: A Python package for automatic wetland mapping, dynamics classification, and cover-type characterisation from multispectral time-series data

Non-peer reviewed Report submitted to Seismica: Correlation of DAS Strain Data and Oceanographic Variables in the North-East Atlantic
Published: 2026-03-17
Subjects: Geophysics and Seismology, Oceanography
DAS recordings close to the coast are influenced by pressure signals from land- and seaward ocean surface gravity waves. The amplitude and period of the signal can serve as proxies for the sea state. Measurements along the cable at greater water depths show secondary microseisms related to the sea state away from the shore. The significant wave height (SWH) and ocean currents along the cable can [...]
Leveraging synthetic data for deep learning denoising and prediction of measured earthquake waveforms
Published: 2026-03-17
Subjects: Earth Sciences, Geophysics and Seismology, Physical Sciences and Mathematics
Single-station recordings of teleseismic earthquakes are inherently complex due to the superposition of numerous seismic phases and their contamination with noise, which can be particularly problematic in urban environments. A detailed knowledge of the wavefield generated by teleseismic earthquakes is critical for high-precision research facilities like those involved in photon science or gravity [...]
Are high-resolution urban datasets necessary for accurate heat exposure modelling in cities?
Published: 2026-03-17
Subjects: Earth Sciences, Oceanography and Atmospheric Sciences and Meteorology
Accurately capturing the spatial variability of urban heat exposure is important for planning heat-resilient cities. While regional climate models have historically simplified urban characteristics, high-resolution urban morphological datasets now present an opportunity to produce spatially accurate heat maps. In this vein, this study evaluates four morphological datasets for Sydney, Australia in [...]
Frictional weakening in the highly mobile 2025 Blatten (Switzerland) rock–ice avalanche

Subjects: Artificial Intelligence and Robotics, Dynamics and Dynamical Systems, Geomorphology, Geophysics and Seismology, Geotechnical Engineering, Multivariate Analysis, Numerical Analysis and Computation, Numerical Analysis and Scientific Computing, Planetary Geomorphology, Planetary Geophysics and Seismology, Risk Analysis
Cascading slope failures in alpine environments are intensifying as glaciers retreat and slope stability adjusts to a warming climate. Yet, the mechanisms governing such large, rapidly evolving events remain poorly understood. The 28 May 2025 rock–ice avalanche from Birch Glacier, Switzerland ($\approx9.3\times10^{6}~\mathrm{m^3}$), which devastated part of the village of Blatten, provides a [...]
Do Less Predictable Tropical Cyclones Induce Larger Damages?
Published: 2026-03-17
Subjects: Atmospheric Sciences, Hydrology, Meteorology, Statistical Models
Tropical cyclones (TCs) cause substantial disaster losses worldwide. Forecast skill for TC track and intensity has been improved by enhanced observations, high-resolution numerical models, advanced data assimilation methods, and applications of machine-learning methods. Yet these improvements have not consistently translated into reduced losses, in part because disaster outcomes depend on many [...]

Emerging Shift in the Indian Summer Monsoon Sensitivity to Equatorial Indian Ocean Sea Surface Temperature Anomalies: Insights from High-Resolution AGCM SST Patch Experiments
Published: 2026-03-17
Subjects: Oceanography and Atmospheric Sciences and Meteorology
Indian Summer Monsoon (ISM) rainfall exhibits strong sensitivity to sea surface temperature anomalies (SSTAs) across four Indo-Pacific nodal regions: The Western and Eastern Equatorial Indian Ocean (WEIO and EEIO), the Western Pacific (WPAC), and the Niño3.4 region. Historically, positive ISM rainfall anomalies are associated with warming in WEIO and WPAC, while warming in EEIO and Niño3.4 [...]
From "Ion-Adsorption" to "Ion-Adsorbed" Rare Earths: Terminological Drift, AI Paraphrasing, and the Erosion of Geochemical Precision
Published: 2026-03-17
Subjects: Earth Sciences, Geochemistry
The rapid adoption of artificial intelligence (AI) tools for writing and paraphrasing is transforming scientific communication. While such tools can improve linguistic fluency, their misuse, particularly when employed to mechanically rephrase text, may introduce subtle but consequential distortions in scientific terminology. In disciplines such as geochemistry, where terminology is closely tied [...]
