If you have a question about this talk, please contact Catherine Pearson.

The oxygen isotope ratio measured in carbonate skeletons of fossilized organisms provides our primary repository of paleoclimatological and temperature reconstructions over the course of Earth history. However, this calculation assumes a knowledge of the oxygen isotope ratio of the ocean, and the geochemical record remains ambiguous as to whether or not this ratio has evolved over time. I will present two new geochemical tools I have used to explore secular variability in the oxygen isotope ratio of the ocean through the Phanerozoic (the last 550 million years).
