A surfeit of good times at the GRC #organicgeochemistrygrc2022! So great to see many @PearsonGroupEPS alumni and friends; apologies to @david_naafs, he should be in the photo too.

What does a 9 inch ice core sound like when dropped down a 450 foot hole? Like this! Credit to @peter_neff for the idea and @Scripps_Polar, @sciencejenna, @GeosciencesPU, @US_IceDrilling, and @paleosurface for the execution!

@david_naafs We have some N data, just not nearly enough to do any stats. Maybe in a few more years.

Follow-up: Here are all the data we have collected over the years on geographic and dietary influence on human d13C values (keratin). EPS 187 class project.
