Nonflood Flow May Be Major Driver of Delta Growth

Sarah Stanley, Freelance Writer

Research Spotlight— Plants and fluctuating river flow work together to balance vertical sediment buildup with sediment delivery to the delta’s edge.  Sea level rise threatens coastal populations around the world. To combat this threat, some communities have employed—or plan to employ—a controversial.... more

Measuring tectonic and climate influence son catchment denudation rates

Editor’s Highlight—   This work presents a dataset from an arid landscape that quantifies topographic control on denudation rates. As such it provides an important end member for the growing understanding of how climate and tectonics shape the Earth’s surface. The extensive dataset consists of catchment-averaged.... more

In Patagonian Lakes, Glacial Meltwater Lies Low

Sarah Stanley, Freelance Writer

From Research Spotlights— A new study reveals key differences in ice–water interactions between glaciers that flow into lakes and glaciers that end in the sea.  High in the southern Andes, a huge ice mass known as the Southern Patagonia Ice Field straddles the border between Argentina and.... more

Faulty Assumptions Impair Earthquake Hazard Assessment in Italy

Sarah Stanley, Freelance Writer

From Research Spotlights— Along faults in the Central Apennine Mountains, weather and landslides may cause rock exposure that is mistakenly attributed to earthquakes.  When an earthquake strikes, vertical movement along a fault can create or add to a distinctive steplike feature known as a.... more

New Tool for Understanding Landscape Evolution in Drylands

Jenny Lunn, Contributing Writer

From Research Spotlights— Combining vegetation distribution models and sediment transport models offers a better understanding of how dryland environments change in response to different factors.  Drylands compose more than 40% of the Earth’s surface. Although they are found on every continent.... more

A Mountain Range’s History Preserved in Ocean Sediments

Terri Cook, Freelance Writer

From Research Spotlights— Fission-track dating core samples from the Gulf of Alaska demonstrates that offshore sediments can be used to reconstruct a mountain range’s changing exhumation patterns.  In southeastern Alaska, the ongoing collision between the North American plate and a microplate.... more
