Where Methane is Emitted Matters for Global Burden
Methane emitted at higher latitude regions (Europe) tends to stay in the atmosphere longer, contributing to higher global concentrations than other regions (Asia, North America).…
A Snapshot of Continental Crust in the Making
New seismic images from the Aleutian Arc show how active volcanic arcs may build new continental crust, highlighting the complex transition at multiple stages.
Soil Biogeochemistry Models Omit Key Processes Due to Geographic Bias
Popular soil biogeochemistry models inadequately represent regionally-important processes and lack transferability, resulting in poor predictions of soil organic carbon stocks in sub-Saharan Africa.
Multi-Scale Fault Roughness Encapsulated in a Friction Law
A new rate- and roughness-dependent friction law incorporates multi-scale fault processes to reproduce earthquake fracture energy scaling.
Pre-Existing Structure and Stress Shape Geothermal-Induced Seismicity
At China’s first Enhanced Geothermal System site, dense seismic observations, integrated with borehole data and stress modeling, reveal weak faults and scale-dependent control of stress…
Model of Complex Blanket Bog Improves Prediction of Peat Expansion
Peat expansion is tightly coupled to the global climate cycle. As a nature-based solution to climate change, we need to know how they will respond to different climate scenarios.
From Grains to Bands: Modeling Deformation in Porous Rocks
How do bands emerge in highly porous rocks? A study based on energy minimization reveals how microscale heterogeneity and stress conditions drive the formation of complex deformation bands.
Recycled Rocks Reveal Subduction Zone Dynamics Off Baja California
High-pressure rocks on Cedros Island were exhumed, eroded, and redeposited into the subduction trench multiple times, reshaping interpretations of ancient plate boundary processes.
Undulations in Auroral Arcs at Plasmaspheric Plume Boundary
Undulations in detached auroral arcs unveil intricate interactions between energetic ions and electromagnetic ion cyclotron waves at plasmaspheric plume boundary.
Small and Large Grains Move Differently in Water
A shift in perspective: flume experiments show that grain entrainment is far more complex than traditional models suggest.
A Digital Twin for Arctic Permafrost Beneath Roads
A physics-informed digital twin uses high-resolution temperature data to track, update, and predict permafrost conditions beneath an Alaskan embankment road.
Martian Aerosols Reveal Dynamics of Dust and Cloud Transport
A new study presents a nine-Martian-year survey of dust and water ice clouds vertical distribution, key drivers of the planet’s climate.
Taking the Pulse of Atmospheric Drag to Predict Satellite Trajectory
Scientists present a new method for estimating the density of the upper atmosphere to account for atmospheric drag when predicting satellite trajectory.
Let’s Not Forget About Long Droughts
Why do conceptual hydrologic models struggle to model long-term droughts? A new study investigates.
Drone Imagery Reveals Marked Variability in Antarctic Snow Roughness
Multi-temporal UAV oblique photogrammetry reveals significant fine-scale variability in Antarctic snow roughness driven by surface type, measurement scale, model choice, and meteorological conditions.
