(Fall, 2011). Advanced graduate-level seminar to discuss research and papers in stable isotope biogeochemistry and geobiology. This year's topic will be "Anatomy of an IRMS". That's right, we will be completely deconstructing our old Finnigan Delta-S to learn how it works (or doesn't). Everything you ever wanted to know about magnetic-sector mass spectrometers. Class will consist of one weekly lecture, and a 2-4 hour lab working on the carcass.
