DHAFGan: A Dense Hybrid Attention Fusion Generative Adversarial Network for Infrared and Visible Image Fusion
Published: 2026-03-22
Subjects: Computer Engineering
Aiming at the problems existing in the current infrared and visible light image fusion algorithms, such as insufficient perception of typical features, poor visual representation of the fusion results, and insufficient utilization of important secondary information, this paper proposes an infrared and visible light image fusion algorithm based on shallow-deep feature extraction and dual-channel [...]
Tectonic reconstruction
Published: 2026-03-21
Subjects: Earth Sciences, Physical Sciences and Mathematics
This is a book chapter that explains tectonic reconstruction techniques, from the field to the plate scale. It is directed at field geologists who want to place their detailed observations in regional (plate) tectonic context, relative to major plates, mantle or spin axis.
Microbial inoculation increases maize yield and root biomass across smallholder farming systems in Rwanda
Published: 2026-03-21
Subjects: Agricultural Science, Agriculture, Environmental Microbiology and Microbial Ecology Life Sciences
Soil degradation, nutrient depletion, and increasing climate stress constrain food productivity across tropical smallholder farming systems. Microbial inoculants have emerged as a promising strategy to improve soil functions and crop yield, yet field-based data from African smallholder systems remain limited, particularly for multi-strain bacterial consortia. Using a multi-strain consortium in a [...]
Benefits of the Sentinel-2 mission triplet constellation in 2025
Published: 2026-03-21
Subjects: Life Sciences
With the first-year extension of Copernicus Sentinel-2A satellite operations nearing its end, an evaluation of its added-value is urgently needed. Here, we show that despite reduced spatio temporal coverage, the additional Sentinel-2A acquisitions in 2025 enhanced the number of usable Sentinel-2 observations over Europe for the March-December period by almost 34%, and at the global scale by more [...]
Spectral signatures in satellite soil moisture reveal irrigation patterns across the contiguous United States
Published: 2026-03-21
Subjects: Earth Sciences, Hydrology, Physical Sciences and Mathematics
Irrigation profoundly alters the terrestrial water cycle, yet its spatial distribution and temporal variability remain poorly constrained. Here, we introduce a new approach to detect irrigation in space based on spectral differences between modelled and satellite-observed soil moisture time series. Using wavelet decomposition, we isolate irrigation-induced variability at sub-annual scales by [...]
Pyxccd: An Efficient Python Package for Break-aware Time Series Analysis of Earth Observation Data
Published: 2026-03-21
Subjects: Engineering
Pyxccd is an open-source, cross-platform Python package (installable via PyPI) for break-aware analysis of Earth observation time series, supporting retrospective disturbance mapping and near-real-time (NRT) monitoring. It implements the two CCDC-like algorithms: COLD (the latest version) and S-CCD 2.0 (state-space formulation to enable NRT application). Additionally, S-CCD 2.0 adds an [...]
Paleomagnetism in tectonics: A user’s guide
Published: 2026-03-21
Subjects: Earth Sciences
Paleomagnetism can reveal the direction of the ancient geomagnetic field recorded in rocks and provides an invaluable quantitative reference for the study of tectonics. This chapter describes the basic principles of how the magnetic field is stored in rocks, how it may be measured, and how common pitfalls in paleomagnetic analysis may be recognized and corrected for. We then explain how [...]
Advances in tree species identification from high-resolution aerial imagery and deep learning
Published: 2026-03-21
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: 2026-03-21
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: 2026-03-20
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 [...]
