Specious Timescales from Sedimentary Layers
Changing environments can dramatically change how quickly layers form in sedimentary rocks, leading to incorrect time estimates.
Using Bayesian Inference to Improve Sediment-Transport Models
A new Bayesian approach is used for the estimation and uncertainty quantification of unobservable parameters required to model tracer evolution in ocean sediment transport and tracer concentrations.
Air Flow Dynamics in Wet Soils: Challenges and Knowledge Gaps
Modeling air flow in wet porous media relies on quantifying the combined role of fluid and media properties and flow dynamics on the microscale displacement mechanisms and macroscale unstable flow.
Stone Chemistry Records Pacific Migration
Scientists used the chemistry of stone artifacts to trace human migration in the Pacific, revealing evidence of long voyages and cultural exchange.
Unlocking the Secrets of Floods: Breakthroughs in Riverine and Coastal Modeling
To enhance flood modeling, it is imperative to gain a comprehensive understanding of the causative mechanisms and cutting-edge models and tools, while also acknowledging their uncertainties.
On-Again, Off-Again Lake Cahuilla Likely Enhanced Earthquakes in Southern California
The disappearance of the ephemeral lake has made earthquakes along the San Andreas Fault even more unpredictable.
How to Find a Volcanic Diamond Mine
New 3D modeling illustrates the mechanism behind the intriguing volcanic eruptions that bring diamonds to the surface.
Volcanoes’ Future Climate Effects May Exceed Standard Estimates
Future releases of sulfur dioxide from volcanoes will likely be higher than the reconstructed historical levels currently used for climate predictions.
Mosses Play Key Roles in Ecosystems from Tropics to Tundra
A global survey of mosses growing on soil found that the somewhat underappreciated plants cover a vast area and perform tasks such as sequestering carbon.
