Recurrent evacuation of mantle mush by mafic recharge in ocean island basalts, recorded by La Palma clinopyroxene
Published: 2025-12-04
Subjects: Earth Sciences, Geochemistry, Physical Sciences and Mathematics, Volcanology
Temporal variations in magma plumbing architecture and magmatic processes can modulate eruption priming, with direct consequences for interpreting pre- and syn-eruptive signals. However, how such processes unfold in low-flux volcanoes remains poorly constrained, leaving a gap in our understanding of eruption precursors. Here we examine the temporal evolution of magmatic processes at La Palma, [...]
Associations between Climate Change and Infectious Diseases: A Systematic Review
Published: 2025-12-04
Subjects: Public Health
Climate change is increasingly recognized as a major driver of infectious disease dynamics, influencing disease distribution, seasonality, and outbreak intensity. This systematic review synthesizes evidence on how climate variability affects infectious diseases and evaluates predictive modeling approaches. Following PRISMA guidelines, we searched Web of Science, PubMed, Embase, and Scopus for [...]
Exacerbation of levee failure with climate change: Insights from ERT monitoring
Published: 2025-12-04
Subjects: Geophysics and Seismology
Climate change is bringing hotter, drier summers and warmer, wetter winters, intensifying winter floods and causing larger seasonal variations in soil moisture. These shifts place increasing stress on levees – many of which were constructed decades or centuries ago – making their current performance challenging to assess. Levee performance depends on limiting water ingress, as increased seepage [...]
Revised History of Pleistocene Vertical Motions in NE Sicily and Southern Calabria, Italy, from 40Ar/39Ar Dating and Fault Zone Morphology
Published: 2025-12-04
Subjects: Earth Sciences, Physical Sciences and Mathematics, Stratigraphy, Tectonics and Structure
Long-term rates of crustal uplift in southern Calabria and NE Sicily are incompletely understood due to limited information about the age of marine terraces at 1.0–1.3 km above sea level (asl). This study provides a new constraint on high-elevation terrace ages through integrated analysis of geochronology, stratigraphy, shoreline modeling, and fault-zone morphology. 40Ar/39Ar step-heating [...]
Hybrid Neural PDE and Conditional GAN Framework for Sparse Co₂ Plume Prediction.
Published: 2025-12-03
Subjects: Geophysics and Seismology, Numerical Analysis and Scientific Computing
Digital twin architectures for geological carbon storage demand uncertainty-aware surrogates capable of rapid plume forecasting under extreme data scarcity. Traditional physics-based simulators are computationally expensive; pure data-driven models lack principled uncertainty quantification. This work presents a hybrid Neural Posterior Density Estimation–Conditional GAN (NPDE-CCGAN) framework [...]
Ocean-arcs as a hidden cooling mechanism during the early Paleozoic
Published: 2025-12-03
Subjects: Earth Sciences
The late Cambrian to end Ordovician is marked by a long-term climatic cooling, culminating with the short lived (<2 Ma) Hirnantian icehouse, before recovering to warmer climates. Increased silicate weathering during the Laurentian Taconic orogeny, driven by the accretion of ocean island arcs and obduction of ophiolites, has been invoked as a causal mechanism to help explain cooling. However, [...]
Advancing CLMU for regional urban climate simulations through WRF coupling: intercomparison with NOAH–SLUCM
Published: 2025-12-03
Subjects: Earth Sciences, Environmental Sciences
Urban areas are highly vulnerable to climate extremes, creating a pressing need for reliable modeling tools to support climate adaptation. The Weather Research and Forecasting (WRF) model is widely used for regional urban climate simulations, and incorporating an alternative urban scheme for long-term climate projections expands the available modeling options and supports more robust simulation [...]
Longitudinal assessment of research in GIScience domain shows a positive impact of reproducible research practices
Published: 2025-12-03
Subjects: Geographic Information Sciences
Reproducibility is increasingly recognised as a cornerstone of rigorous science, prompting many publishers to require full documentation, data and software access, and archiving of study materials. Yet prior work shows that such practices, that are essential for communicating research transparently, remain comparatively low in the Geographic Information Science (GIScience) research community. To [...]
Evaluating Trade-offs Between Irrigation Profit and Streamflow Depletion Using a Hydro-Economic Model
Published: 2025-12-03
Subjects: Earth Sciences, Environmental Sciences, Hydrology, Physical Sciences and Mathematics, Water Resource Management
Groundwater overexploitation can reduce flows in connected rivers through streamflow depletion, which threatens ecosystems and downstream users who often rely on these flows for their economic wellbeing. Quantifying groundwater-surface water interactions and their economic trade-offs remains challenging for sustainable water management. This study integrates analytical groundwater and streamflow [...]
Present and future coastal flooding hazard for Long Island, NY and Long Island Sound (NY/CT), USA.
Published: 2025-12-02
Subjects: Oceanography, Oceanography and Atmospheric Sciences and Meteorology
Coastal flooding and the associated damages due to storms are increasing with sea level rise around the world, with regional variability in the severity of impacts., Researchers and resource managers need to better understand and predict the future shifts in coastal flooding due to these processes to plan for resilient and sustainable communities. Here we present an analysis of long-term [...]
Where were the mountains and how big were they?
Published: 2025-12-02
Subjects: Earth Sciences
Constraining past topography and the shape of Earth’s surface is the next frontier in palaeogeography and full-plate tectonic modelling. Mountains are highly dynamic on geological time scales, growing in response to tectonic processes such as subduction and continent collision, and eroding as they are exposed to precipitation and time. Mountain ranges regulate atmospheric circulation and enforce [...]
A lithium isotopic perspective of basalt weathering: Cycling of Li and its mobility relative to Ca and Mg
Published: 2025-12-01
Subjects: Earth Sciences
Lithium isotope composition (δ7Li) has been extensively utilized to trace silicate weathering. Although the direction and magnitude of Li isotope fractionation during Li adsorption onto secondary minerals are well understood, the relative importance of Li partitioning via its adsorption vis-à-vis structural incorporation into clay minerals on overall Li isotope fractionation remains poorly [...]
Formation and alteration of magnesite nodules from Kunwarara, Queensland, Australia, as an analogue to Mg-carbonate formation on Mars
Published: 2025-11-30
Subjects: Planetary Sciences
Magnesite (MgCO3) is a magnesium carbonate mineral that records the aqueous environmental conditions of its formation. On Earth, magnesite forms in metamorphic, diagenetic or pedogenic environments, and distinguishing between these environments is critical for understanding the nature of fluid chemistry during magnesite precipitation. Magnesite has been identified across the Nili Fossae region on [...]

The Formation of Seaward-dipping Reflectors in Volcanic Margins: Insights from High-resolution Visco-elasto-plastic Geodynamic Models with Extrusive Surface Processes
Published: 2025-11-29
Subjects: Physical Sciences and Mathematics
Seismic reflection data from volcanic margins show thick packages of seaward-dipping reflectors (SDRs) that are commonly interpreted as buried subaerial lava flows. The origins of SDRs remain debated with proposed mechanisms including (1) syn-kinematic extrusion of lava flows on extended continental crust, (2) progressive rotation of subaerial lava flows due to volcanic loading and magmatic [...]
