I'm excited to start the sample preparation for cosmogenic dating at the University of Cincinnati! We'll be following the procedure of @erraticscience.bsky.social to use 36Cl on whole rock basalt on our 1.1. Ga old samples from the Lake Superior basin. 🧪👩🔬
✔️ Etching the samples in nitric acid.

Back from the field! We've been collecting samples for cosmogenic radionuclide dating using 36Cl on whole rock. We're interested in fluvial incision and waterfall retreat rates in the Western Lake Superior Basin. This is also a beautiful study site with Temperance, Gooseberry and Cascade Rivers!

First day of sample preparation for cosmogenic dating. We're starting with crushing, milling and sieving the sample material.

Today was the first day of our annual NSF funded project on the Lake Superior Basin. I presented my work on the lithological controls on erosion processes in bedrock rivers and the fluvial geomorphology on the North Shore. 🏞️🌊🏔️🧊

This week, I attended the @csdms.bsky.social annual meeting, where I presented my work on the control of lithological properties on bedrock river erosion, using field and flume measurements. I enjoyed this meeting with great keynote talks, lots of time for interaction and daily workshops! 🏞️💻

Happy to see @stanthonyfallslab.bsky.social here! I'm looking forward to seeing more of our amazing research! 🏞️🌊
