4/4 Fun backstory: this idea started as a final project in our Advanced Sedimentology & Stratigraphy course (EOS 423) at UVic (@seos-uvic.bsky.social). Really fun to see the classroom project grow into a full paper, and I learned a lot about numerical modeling and stratigraphy along the way!

3/4 A key prediction is that transport-driven isotope excursions should occur in very specific stratigraphic contexts: tied to changes in the coastline (transgression/regression). If the same signal appears outside those contexts, a global driver is more likely.

2/4 We built a simple numerical sediment-transport model to track tracers (like δ13C of carbonates) through sediment formation, transport, erosion and deposition. The key result: erosion, reworking, and lateral transport alone can generate stratigraphically correlative isotope excursions.

I really wonder what the GOP's vision of America in 30 years is. Do they want a country that doesn't do fundamental research, without the world's best research universities, with the citizens working in factories assembling iPhone cases?

your papers and teaching material were a great resource and inspiration for me when I designed my 2nd year geochemistry course. thank you for your work! 🏳️‍⚧️

🧐.. this is very true 😐
