A nice article about our new QSR paper on rapid precipitation, vegetation, and fire transitions in the Turkana Basin!

Rachel Lupien @loopdlupien.bsky.social · 13/07/2026

My postdoc, Julian Traphagan, has a new paper out in Organic Geochemistry! He performed a series of experiments on our GC-IRMS @au.dk and showed that spiking low-conc samples with standards could make some unobtainable compound-specific n-alkane dD measurements now obtainable. Check it out!
