Erosion of the Santa Monica Mountains
Erosion of the Santa Monica Mountains
Summary: This project uses basin-averaged 10Be erosion rates from streams draining the Santa Monica Mountains, California, to elucidate the relationship between erosion and uplift along the Malibu Coast and Santa Monica Faults.

The Woolsey Fire and 10Be
The Woolsey Fire and 10Be
Summary: This project seeks to understand how sensitive 10Be measured from stream sand is to widespread erosion associated with recent, large-magnitude geomorphic events, and this study uses the 2018 Woolsey Fire as a case study.

Laurentide Ice Retreat
from the Sturgis Moraine
Laurentide Ice Retreat
from the Sturgis Moraine
Summary: This project uses 10Be and in situ 14C exposure-age dating on glacial erratics positioned on the Sturgis Moraine in south-central Michigan to determine when the Saginaw Lobe of the Laurentide Ice Sheet retreated after the Last Glacial Maximum.

Schmidt hammer exposure-age dating
in the Great Lakes region
Schmidt hammer exposure-age dating
in the Great Lakes region
Summary: This project seeks to establish a Schmidt hammer exposure-age calibration curve for the Great Lakes region, which if successful will allow for cost-effective and rapid exposure-age estimation of erratics and the landforms on which they are found.

Dating eskers with 10Be
Dating eskers with 10Be
Summary: This project will use 10Be dating to determine the deposition and/or exposure age of an esker in the Upper Peninsula of Michigan.

Updating the Global 10Be Erosion Database
Updating the Global 10Be Erosion Database
Summary: This project seeks to reanalyze a global database of 10Be erosion rates by updating Portenga and Bierman (2011, Understanding Earth's Eroding Surface with 10Be, GSA Today) with hundreds of new bedrock erosion rates and thousands of new basin-averaged erosion rates inferred from measurements of 10Be.
