What Electrons Can Tell Us About the Speed of Sand
A new sediment tracer uses the interactions between radiation, charge, and the Sun to uncover the hidden transport histories of sand grains.
When Projecting Coastal Resilience, Sediment Compaction Is Key
The addition of new sediment helps build up lowland environments like deltas and marshes, but it also compacts materials beneath it—a vital, but often overlooked, factor in landscape evolution studies.
Tracking Subsidence on Deltas With Fiber-Optics
Fiberoptic strain meters capable of measuring micron-scale subsidence reveal a Holocene sediment package on the Mississippi Delta that is mostly stable.
Glacier Advance and Retreat: Insights From the Top of the World
New dating of glacial features reveals predictable glacier behavior in response to climate warming and cooling in the Everest region in the past 8,000 years.
Growth That Economists Would Envy
A new study reveals how small cracks turn into gigantic submarine slides.
Can We Better Predict Coastal Change?
A new special collection invites studies on a new era of models and knowledge that provide predictions or insights into predictability in coastal geomorphology.
Good or Bad Jam? Modeling Boulders’ Fate at Constrictions
A new modeling framework to assess the likelihood of jamming at constrictions can be used to support the design of effective mitigation measures and reduce risk in debris flow prone areas.
Running Water on Topographic Data to Better Delineate Channels
Two-dimensional hydraulic simulations are a powerful tool to identify process domains such as channels, hillslopes, and floodplains in high-resolution topographic data.
Extreme Lithium Isotope Fractionations During Intense Weathering
Extreme lithium fractionation is observed when primary minerals in andesite are transformed to secondary clay minerals and then to oxides with intensive chemical weathering in a tropical climate.
