3-D Elastic Time-Reverse Imaging of a Linear Void Anomaly
Published: 2026-01-28
Subjects: Geophysics and Seismology
Imaging meter-scale subsurface heterogeneities such as void spaces remains a difficult task for most established near-surface seismic methods. One strategy for addressing this challenge is to isolate and use surface waves backscattered from lateral heterogeneities to identify and characterize the sources of scattered energy. Seismic methods associated with this strategy, though, often require [...]
Ocean climate variability and travel surveillance data inform understanding of global dengue dynamics
Published: 2026-01-28
Subjects: Public Health
Oceanic-atmospheric interactions significantly influence regional rainfall and vector-borne disease dynamics. Travel-related dengue cases serve as effective sentinels for dengue transmission, yet the impact of sea surface temperature (SST) variability on their occurrence remains under explored. Here we analyzed 2000–2019 GeoSentinel traveler dengue data alongside ERA5 SST and precipitation [...]

This study assessed policies across health and supporting sectors to evaluate their contribution to building a climate-resilient health system (CRHS) and strengthening emergency response capacity. We conducted a [...]
Exploring the compositional variability of magmas erupted at La Soufrière volcano, St Vincent, using chemostratigraphy and new 40Ar/39Ar ages
Published: 2026-01-27
Subjects: Education
The temporal compositional variation of individual volcanic centres is key to understanding magmatic processes in the underlying crust. La Soufrière volcano, St. Vincent, Lesser Antilles, has erupted predominantly basaltic andesite magmas for hundreds of thousands of years. Sampling of the recently exposed crater walls at La Soufrière reveals that sequentially emplaced crater lavas, feeder dykes, [...]
Automating glacier facies classification: pan-European dataset and deep learning baseline
Published: 2026-01-27
Subjects: Artificial Intelligence and Robotics, Glaciology
Glacier facies play a critical role in understanding the mass balance of glaciers, offering insights into accumulation and melting processes. Large-scale mapping of glacier facies from satellite data is therefore essential for monitoring glacier response to climate change and informing climate policies. In this study, we present the largest glacier facies dataset ever compiled for Europe, [...]
Stadiums as climate-exposed socio-technical infrastructures: a scoping review of fragmented risks and emerging challenges
Published: 2026-01-27
Subjects: Civil and Environmental Engineering, Environmental Public Health, Environmental Studies
Stadiums are among the most climate-sensitive infrastructures in global sport, yet the evidence available to characterise their climate-related risks remains fragmented. Although billions of spectators attend sporting events each year and climate change is recognised as a multiplier of existing hazards, research on stadium environments continues to treat risks separately. Heat is examined through [...]
Near-total loss of buttressing stresses observed on Pine Island Ice Shelf, West Antarctica
Published: 2026-01-27
Subjects: Earth Sciences, Glaciology, Physical Sciences and Mathematics
Ice shelves, the floating extensions of the Antarctic Ice Sheet, provide critical buttressing stresses that resist the seaward flow of ice and help set the position of the grounding line, where the ice goes afloat. As buttressing stresses are diminished by thinning or fracturing and collapse of the ice shelf, glaciers tend to accelerate. Here, we focus on the response of Pine Island Ice Shelf [...]
Smoothing Earth’s surface: the complexity of soil texture class transitions

Subjects: Applied Statistics, Dynamical Systems, Dynamic Systems, Environmental Sciences, Non-linear Dynamics, Numerical Analysis and Computation, Numerical Analysis and Scientific Computing, Ordinary Differential Equations and Applied Dynamics, Soil Science, Statistical Models, Statistical, Nonlinear, and Soft Matter Physics
Soil depth functions are essential for analysing, modeling, understanding and visualising soil profiles. While robust methods existed for continuous properties, soil texture is typically reported as discrete classes, and no established approach exists to interpolate soil categorical information with depth. Here, we introduced phySplines, a physics-informed, analytically solvable spline for [...]
A Quality-Control Procedure for Bio-Optical Applications of Hyperspectral Radiometric Upwelling Radiance and Downwelling Irradiance Profiles Measured by BioGeoChemical-Argo Floats.

In the case of water-saturated, granular deposits that are at risk of liquefaction, engineers need reliable information about the spatial extent of soil deformation in the event of liquefaction. It is not so important for them to know the exact location of the first failure. However, existing anal-yses primarily deal with the triggering of liquefaction and offer only limited information on how [...]
Exploring Potential Mechanisms for the Initiation of Solifluction Patterns
Published: 2026-01-25
Subjects: Physical Sciences and Mathematics
Hillslopes in arctic regions commonly display large-scale features—known as solifluction patterns—that form due to the exceedingly slow downhill movement of frost-heaved soil. Here we use a combination of remote sensing data, linear stability analysis, numerical modeling, and review of a wide range of literature to evaluate several working hypotheses for the necessary and sufficient conditions [...]
