Geological controls on Underground Hydrogen Storage in depleted gas fields
Published: 2026-03-27
Subjects: Earth Sciences, Environmental Sciences, Geology, Oil, Gas, and Energy, Other Civil and Environmental Engineering, Sustainability
The geological storage of hydrogen is an alternative for large-scale energy storage in support of expanding renewable energy systems. The North Sea has hundreds of depleted gas fields that are potential storage sites. Robust screening procedures are necessary to select the most suitable reservoirs in terms of geology. This study investigates the geological controls on hydrogen storage in depleted [...]

Understanding the mechanical response of Antarctic ice shelves to surface meltwater is critical for evaluating their structural stability. This study presents 11 austral summer seasons (AS 2015-2016 to AS 2025-2026) assessment of supraglacial melt pond dynamics and their mechanical implications for the Nivlisen Ice Shelf grounding zone using Landsat-8/9 imagery combined with in-situ validation [...]

Characterizing phase assemblages in igneous rocks and the chemical variability within these phases is the fundamental basis of many petrological investigations. We present mineralML (mineral classification using Machine Learning), an open-source Python package that classifies common igneous minerals based on oxide chemical data, with prediction scores. mineralML employs a two-stage neural [...]
Nearly three decades of laser altimetry reveal strong regional contrasts and glacier-driven ice losses in Greenland
Published: 2026-03-27
Subjects: Earth Sciences, Physical Sciences and Mathematics
The Greenland Ice Sheet, a major contributor to sea-level rise, loses mass through complex processes that are not fully understood. Laser altimetry provides direct and accurate measurements of ice sheet surface elevation. Here, we present the first continuous, laser altimetry-based annual reconstruction of Greenland Ice Sheet mass change from 1994 to 2020 at 1 km horizontal resolution. Our novel [...]
Seasonal Anomaly Detection in the Halda River Using a Multivariate Deep Learning Framework
Published: 2026-03-27
Subjects: Civil and Environmental Engineering, Earth Sciences, Engineering, Mechanical Engineering
Monitoring river water quality is essential to preserving ecological integrity, especially in ecologically significant rivers like the Halda, which is renowned for its natural freshwater carp spawning. This study presents a deep learning-based approach using a deep autoencoder neural network for unsupervised anomaly detection in water quality data. Two-year time-series data including daily [...]
Spatiotemporal relationships, influencing factors and policy implications of coastal man–land system spatial resilience based on interpretable machine learning models: A case study of China’s southeastern coastal region
Published: 2026-03-26
Subjects: Geography
Spatial resilience, as a projection of system resilience at the landscape scale, offers a novel spatial interpretation for analyzing man–land interactions in coastal zones. This study builds an evaluation system from “element-landscape-system” levels, based on the conceptual framework of spatial resilience in coastal man–land systems. It examines the spatiotemporal evolutionary features of [...]
Research on marine litter detection based on CNN-Transformer heterogeneous parallelism
Published: 2026-03-26
Subjects: Electrical and Computer Engineering
Aiming at strong background interference and low detection accuracy of small/deformed targets in marine debris detection, this paper develops a high-precision lightweight intelligent detection and recognition system. A multi-scenario dataset is built and data augmentation is used to tackle sample scarcity and domain shift; a CNN-Transformer heterogeneous parallel model YOLO-Trans is designed on [...]
InSARLite: An Open-Source GUI for Streamlined InSAR Time Series Processing
Published: 2026-03-26
Subjects: Graphics and Human Computer Interfaces, Other Earth Sciences, Programming Languages and Compilers
Interferometric Synthetic Aperture Radar (InSAR) is a powerful technique for measuring surface deformation at high spatial resolution over large areas. Despite its demonstrated value across geohazards and Earth-surface processes, broader adoption is often limited by the complexity of end-to-end processing workflows and the technical overhead required to execute them. To reduce this barrier, we [...]
Spectral seismic interferometry: Efficient monitoring of unbiased seismic velocity changes at high temporal resolution
Published: 2026-03-26
Subjects: Physical Sciences and Mathematics
Ambient noise based monitoring of subsurface velocity changes does not require the explicit retrieval of Green's functions by correlation. Velocity variations can directly be observed from the fluctuations in the spectrograms of ambient noise time series or their cross-spectra. This approach is more resource efficient than the conventional Green's function based monitoring and ideally suited for [...]
Comparative analysis of mass balance estimates since 1959 at Mittivakkat Gletsjer (SE Greenland)
Published: 2026-03-26
Subjects: Physical Sciences and Mathematics
Mittivakkat Gletsjer (MIT) has the longest glaciological surface mass balance (SMB) record of any peripheral glacier in Greenland. In this study, we utilize the glaciological SMB record, calibrate SMB from the Regional Atmospheric Climate Model (RACMO), and calculate geodetic mass balance (MB) to provide a multi-methodic assessment of trends in SMB. Glaciological SMB and modelled SMB correlate [...]

Published: 2026-03-26
Subjects: Physical Sciences and Mathematics
The Sichuan-Yunnan region is a critical tectonic zone for understanding continental deformation and seismic hazards. We developed a hybrid deep-learning strategy that integrates multi-scale phase picking and high-precision first-motion polarity identification, significantly improving regional seismic monitoring. This approach yielded a unified 2013-2022 high-resolution dataset, including -180,000 [...]
Dataset of DInSAR wrapped phase signals for AI-based automated detection and classification of mass movements

With the growing use of Artificial Intelligence (AI) in remote sensing of mass movements, available datasets for model training and validation are increasingly needed. Although Differential Synthetic Aperture Radar Interferometry (DInSAR) is a widely used technique for studying mass movements, wrapped interferograms remain less exploited, and the importance of geomorphological expertise in their [...]
Buoyancy of volatile-rich kimberlite melts, magma ascent, and xenolith transport
Published: 2026-03-26
Subjects: Physical Sciences and Mathematics
Kimberlite melts are primary carriers of mantle-derived carbon and hydrogen, playing an important role in Earth’s deep carbon cycle and diamond transport. Their low densities, viscosities, and vapor exsolution enable fast ascent rates. Ascending from the upper mantle, kimberlite melts incorporate xenoliths and xenocrysts and exsolve volatiles. These processes alter their initial composition, [...]
MJO Phase-Response Diagnostic Skill Reflects Convective Regime Contingency Beyond Coupling Strength Across Tropical Sites
Published: 2026-03-26
Subjects: Physical Sciences and Mathematics
MJO phase composites are the standard tool for building tropical rainfall diagnostic frameworks. The coupling strength between the MJO phase and local rainfall is routinely used to justify their application. Whether coupling strength alone guarantees diagnostic skill — or whether the nature of the underlying convective regime is the additional governing condition — has not been examined. We [...]
Urban Green Cover and Land Surface Temperature in Ho Chi Minh City: A Remote Sensing Analysis of Vegetation Cooling Effects Across Historical Development Rings, 1990–2025
Published: 2026-03-26
Subjects: Environmental Monitoring
Ho Chi Minh City's 11.3 million residents live in a landscape shaped by four political regimes — French colonial, wartime, socialist, and market-era — each of which built the city it needed and left the green space debt for the next. Using Sentinel-2 and Landsat satellite imagery from 1990 to 2025, we map vegetation cover and surface temperature across the city at 100-meter resolution and trace [...]
