Project Title

Volcanic Proxies Predating K-T Boundary

Certificate(s): Environmental Studies

I analyzed mercury concentrations in rock cores from Mexico, India, the United States and Israel. I learned how to properly prepare samples to be processed by the mercury-analysis machine. I used the wide assortment of data I accrued to aid Professor Keller’s research showing extensive volcanic activity predating the Cretacious-Paleogene boundary, which marks the time period when the dinosaurs went extinct. With access to such great data, I have decided to continue working with her during the fall of my junior year and she will be my first junior paper adviser. Through this internship, I gained excellent experience in a paleontological laboratory that will help me choose a career path in the very near future.
