Biophysical structure and particle dynamics of an algal bloom within a mesoscale eddy
Abstract Mesoscale eddies create dynamically distinct environments where thermohaline fronts partition the biological and optical structure of the upper water column. How these fronts organize the vertical and lateral structure of spring blooms is a longstanding observational challenge, largely because the bloom environment evolves rapidly across ...

Interferometric Synthetic Aperture Radar (InSAR) for Monitoring Seasonal Snow
Abstract Interferometric Synthetic Aperture Radar (InSAR) offers a potential pathway for measuring seasonal snow water equivalent (SWE) and snow depth at spatial and temporal scales needed for basin‐scale hydrology. First proposed for seasonal snow more than 25 years ago, InSAR uses repeat‐pass radar phase differences to estimate changes in SWE or ...

Abstract Water ice is an important rock‐forming mineral, both on the Earth and on various extraterrestrial bodies. Naturally occurring ice is often “dirty”–an intimate mixture with harder mineral grains, which can have significant effects on the bulk properties of the aggregate. We have used neutron powder diffraction, with in situ triaxial deformation,

Ice Spheres as Model Snow: Tumbling, Sintering, and Mechanical Tests
The snow microstructure is crucial for the mechanical behavior of snow, but is usually simplified in numerical models. In Discrete Element Models (DEM), often used in snow mechanics, the microstructure is typically represented by sphere assemblies.

Advanced Sorbent Materials in Solid‐Phase Extraction: A Decade of Innovation and Future Perspectives
This review systematically summarizes five families of advanced sorbent materials for solid‐phase extraction (SPE): nanocarbons, porous frameworks (MOFs/COFs), smart polymers, biomass‐derived sorbents, and multifunctional composites. Key molecular interactions (π–π stacking, hydrogen bonding, electrostatic attraction, host–guest recognition) are ...

Microstructure-based modelling of snow mechanics: experimental evaluation of the cone penetration test [PDF]
Snow is a complex porous material presenting a variety of microstructural patterns. This microstructure largely controls the mechanical properties of snow, although the relation between the micro and macro properties remains to be better understood ...

CO2‐Derived Architected Carbons for Sustainable Energy Conversion and Storage
CO2‐derived carbon architectures are systematically engineered via thermochemical, electrochemical, and hybrid pathways to tailor electronic structure, interfacial charge transfer, and catalytic functionality. These materials demonstrate versatile performance across electrocatalysis and energy storage, establishing a coherent framework that links ...

Sensitivity of Spatial Snowmelt Simulations to Radiative Forcing and Model Top Layer Thickness
Abstract Hydrologic models applied in snow‐dominated basins are typically evaluated by comparing simulated outputs, such as snow water equivalent and streamflow, with observations. However, this approach may overlook the energy balance aspect of snow modeling. Snowmelt initiation and rate are primarily determined by the net energy balance, which varies

Snow mechanics: from snow microstructure to avalanche formation
Snow is a fascinating material. Its composition is relatively simple, mainly air and ice, but the arrangement of these components in three dimensions is extremely diverse. This diversity of microstructure, often reduced to discrete snow types, originates from different snowflake growth mechanisms in the atmosphere and the continuous evolution of snow ...
