Advances in tree species identification from high-resolution aerial imagery and deep learning
Published: 2026-03-20
Subjects: Forest Management, Other Forestry and Forest Sciences
Tree species diversity shapes forest functioning, carbon storage, and ecosystem resilience, yet species-level inventories remain limited outside local studies. High-resolution aerial imagery and deep learning now enable individual tree crowns to be mapped at high spatial detail, offering new pathways for biodiversity and climate impact assessments. We synthesize 103 studies (2017–2024), [...]
Bimodal seismic-aseismic behavior of a weakly coupled megathrust segment revealed by kinematic analysis of a seismic swarm and slow slip event offshore Copiapó, Chile
Published: 2026-03-20
Subjects: Earth Sciences, Geophysics and Seismology, Physical Sciences and Mathematics
A seismic swarm occurred in Chile in 2023, in a region well known for hosting this type of seismicity, the Atacama region, and more precisely within the low coupling zone of Barranquilla. It started on August 26th and lasts about 6~weeks, ending early October. Thanks to our high-density small-scale GNSS network, we recorded the spatio-temporal evolution of surface deformation generated by a slow [...]
Robust Uneven Shift of Extreme Storm Surges Observed in Data Sparse Northeast Indian Ocean Cities
Published: 2026-03-19
Subjects: Earth Sciences, Engineering, Risk Analysis, Statistics and Probability
Reanalysis-driven storm surge datasets enable extreme analysis in data-sparse regions, but most studies translate these time series into extremes using a single statistical model, leaving model-selection uncertainty unquantified. In this study, we analyze ERA5-forced surge residual dataset (1950–2024) from Copernicus Climate Change Service for 11 Northeast Indian Ocean (NIO) cities using an [...]
Comprehensive Inventory of Coseismic Landslides Triggered by the 2023 Kahramanmaraş Earthquakes, Türkiye
Published: 2026-03-19
Subjects: Geology, Geomorphology, Geophysics and Seismology
We provide two geospatial inventories covering ~80,000 km² in southern Türkiye for the 6 February 2023 Kahramanmaraş earthquake sequence: (i) a coseismic landslide polygon inventory including 20,270 landslides and (ii) a pre-earthquake geomorphic inventory of pre-existing slope instability including 4,495 landslide polygons. Coseismic landslides were mapped by systematic expert visual [...]
Sustaining Life on the Fault Line: Women’s Social Reproduction and Grassroots Disaster Governance in Yogyakarta, Indonesia
Published: 2026-03-19
Subjects: Environmental Studies, Human Geography, Nature and Society Relations
Mainstream disaster resilience studies overwhelmingly privilege top-down institutional frameworks, leaving the socio-economic and care-oriented contributions of women undertheorized as constitutive forces in how resilience is actually produced at the community level. This study examines how women’s everyday practices and organizational capacities shape disaster preparedness, response, and [...]

Investigating the application of LLMs to invertebrate palaeontology through the development of automated taxonomy assistants for brachiopod identification
Published: 2026-03-19
Subjects: Earth Sciences, Physical Sciences and Mathematics
Taxonomic identification is a central practice in palaeontology, underpinning biostratigraphic correlations, palaeobiogeographic reconstructions, and analyses of macroevolutionary patterns. Despite its importance, taxonomy depends on a limited number of specialists and on the synthesis of extensive descriptive literature that is often difficult to access. Recent developments in artificial [...]
Polymineralic synneusis in silicic magmas revealed by megacryst-inclusion orientation relationships
Published: 2026-03-19
Subjects: Earth Sciences
Crystal aggregation via synneusis is well-documented in many common igneous minerals, such as quartz and olivine. Synneusis is typically described as a monomineralic process whereby two crystals of the same mineral adhere in specific low-energy orientation relationships. In contrast, unlike minerals are generally assumed to be antipathetic. Nonetheless, the occurrence of polymineralic synneusis [...]
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 [...]
