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…
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.
Drivers of Day-to-Day Temperature Swings Across Continents
Abrupt temperature swings aren’t random—large-scale air mass shifts and seasonal processes drive day-to-day variability across major Northern Hemisphere regions.
Managed Agriculture Hinders Predictability of Critical Zone Features
Intensively managed agricultural sites show behavioral shifts of the critical zone system and subsystems thus impacting predictability.
Toward Marine Cloud Brightening at Scale: A Science Agenda
Marine Cloud Brightening (MCB) is a Solar Radiation Management (SRM) solution to cool the planet by changing the albedo of low-altitude marine clouds to increase reflected shortwave radiation.
