Subjects: Artificial Intelligence and Robotics, Environmental Sciences, Hydrology, Software Engineering
Deep learning has demonstrated strong potential for improving hydrological predictions, yet its practical adoption remains limited by software complexity, infrastructure requirements, data governance constraints, and fragmented analytical workflows. This study presents Hydro AI Lab, an AI-assisted client-side scientific workflow platform that enables end-to-end hydrological analysis, including [...]
Extreme changes in water level regenerate reed stands and a stable water regime leads to die-off: lessons from the analysis of 40-year satellite times series observations in a shallow lake ecosystem.

Subjects: Earth Sciences, Ecology and Evolutionary Biology, Hydrology, Natural Resources and Conservation, Physical Sciences and Mathematics, Terrestrial and Aquatic Ecology, Water Resource Management
Reed wetlands are key to the productivity of shallow lakes, and their condition is tightly governed by water level variability. Using long-term satellite observations, we provide the first analysis linking hydrology and reed vitality at Lake Neusiedl, a major climate sensitive wetland system in the Pannonian Basin. We assembled a 40-year record (1985–2025) of Landsat derived Enhanced Vegetation [...]
HydroModelSpec: Toward Standardized Machine Learning Model Exchange in Hydrology
Published: 2026-05-30
Subjects: Environmental Sciences, Hydrology, Software Engineering
The rapid growth of deep learning models for hydrological forecasting (e.g., CNNs, LSTMs, Transformers) has created a fragmented ecosystem where trained models remain tied to their original frameworks, environments, and institutions. Despite substantial investments in model development, the hydrological community lacks a generalized structure for packaging models with their architecture, training [...]
Awareness and Action: An Exploration Between Public Perception and Space Industry Priorities Regarding Sustainability
Published: 2026-05-30
Subjects: Environmental Sciences, Environmental Studies, Natural Resources and Conservation, Natural Resources Management and Policy, Nature and Society Relations, Sustainability
As issues regarding sustainability continue to grow more urgent and prevalent to everyday life, it is important to recognize whether society fully understands what is occurring. The low earth orbit is at threat of overcongestion, and the environment is experiencing higher rates of pollution due to rocket launches, calling for the need for the government and public to engage in this issue. [...]
R-critical constraints on relamination efficiency: The role of mechanical coupling in continental crust recycling
Published: 2026-05-30
Subjects: Geochemistry, Geology, Geophysics and Seismology, Tectonics and Structure, Volcanology
Relamination—the reincorporation of deeply subducted continental crust into the overriding plate—has been proposed as a major mechanism for continental growth and differentiation. While numerical models and high-pressure experiments demonstrate the thermochemical feasibility of this process, a fundamental question remains: under what mechanical conditions is relamination sufficiently efficient to [...]
ENSO Modulation of the Amazonian Low-Level Jet: More Moisture, Less Rain, and the Role of Land Surface Reception
Published: 2026-05-30
Subjects: Climate, Hydrology, Meteorology
The Amazonian Low-Level Jet (ALLJ) carries moisture from the tropical Atlantic coast into the basin interior, sustaining wet-season convection. Here we analyze 45 years of ERA5 reanalysis (1979–2023), 44 years of CHIRPS precipitation (1981–2024), GRACE terrestrial water storage (2002–2025), and SMAP root-zone soil moisture (2015–2024) to determine how ENSO modulates this transport pathway and its [...]
Future Strengthening of North Atlantic Anthropogenic Carbon Transport Despite AMOC Weakening
Published: 2026-05-30
Subjects: Physical Sciences and Mathematics
The North Atlantic is a major hotspot for the uptake, accumulation, and storage of anthropogenic carbon (Canth), processes that are closely linked to the Atlantic Meridional Overturning Circulation (AMOC). However, the role of ocean transport in driving this accumulation remains poorly constrained, leading to uncertainty in future carbon uptake and circulation changes under climate forcing. CMIP6 [...]
Unequal weather exposure across teams and groups at the 2026 FIFA World Cup: an event-based analysis using hourly reanalysis
Published: 2026-05-30
Subjects: Climate, Environmental Studies, Human Geography
The connection between climate change and sports is evident, as sports contribute to environmental challenges, while climate change impacts the conditions for playing, organizing, and enjoying sports. In professional football, heat, humidity, rain, wind, and insufficient recovery time at night can influence player health, physical stress, and game performance. Evaluations of the 2026 FIFA World [...]
An adaptive hybrid model for wildfire front forecasting based on cellular automata, multi-agent UAV observations, and binary data assimilation: A case study of the 2021 Dixie Fire
Published: 2026-05-29
Subjects: Environmental Studies
This study presents a retrospective case-study evaluation of a hybrid framework for daily wildfire-front forecasting during the 2021 Dixie Fire in California, USA. The framework couples a stochastic cellular automaton (CA) with a multi-agent system (MAS) of simulated UAV observations and a lightweight binary data-assimilation scheme. The model uses topography, vegetation, fuel proxies, and [...]
A Petrographic P-Axis as an Independent State Coordinate of Coal Organic Matter: Decoupling of Organic Sulfur and Inorganic Fe–S Subsystems
Published: 2026-05-29
Subjects: Engineering, Physical Sciences and Mathematics
This study proposes an architectural framework for coal organic matter in which geochemical behavior emerges from the interaction of partially independent subsystems rather than from a single maturity or redox gradient. Using a globally compiled coal dataset, we introduce the P-axis—a petrographic coordinate derived exclusively from the balance between gelified and tissue-preserved vitrinite [...]
Hydrogen and CO₂ Co-Storage in Mature Reservoirs: A New Frontier for the Energy Transition
Published: 2026-05-29
Subjects: Engineering
The shift towards low-carbon energy systems necessitates large-scale strategies for managing carbon dioxide (CO₂) and storing renewable energy. Geological formations beneath the Earth's surface, which have been traditionally utilized in the petroleum sector for extracting hydrocarbons, present considerable potential for energy transition technologies like geological carbon storage (CCS) and [...]
A benchmark deep learning dataset for the classification of supraglacial lake drainage mechanism across the central-west Greenland Ice Sheet
Published: 2026-05-29
Subjects: Artificial Intelligence and Robotics, Earth Sciences, Glaciology, Numerical Analysis and Scientific Computing, Physical Sciences and Mathematics
Supraglacial lakes on the Greenland Ice Sheet drain through physically distinct pathways: hydrofracture, moulins, lateral stream routing, and crevasse-fields. Each drainage mechanism carries unique implications for ice sheet dynamics. Existing automated classifications reduce each lake's drainage behavior to a time-series of scalar values representing the observed water surface-area and classify [...]

NOVEL & RAPID PROCESSING OF UAS IMAGERY FOR TARGETED CYANOBACTERIAL HARMFUL ALGAL BLOOM SAMPLING
Published: 2026-05-28
Subjects: Environmental Sciences
Unmanned aerial systems (UAS) are an efficient way to monitor and sample algal biomass including cyanobacterial harmful algal blooms (CyanoHABs). However, conventional methods to create a UAS orthophoto of homogeneous water surfaces often produce a patchy, smoothed, or spatially inaccurate output. In this study, we developed a novel method to interpolate a spectral index from a central pixel in [...]
