About Me

My name is Sam, I am a recent PhD graduate from the School of Earth Sciences at The Ohio State University. My primary research interests are in paleoceanography, using geochemical techniques on marine sediments to investigate environments of the past, as well as computational techniques to model marine processes. My dissertation is made up of three projects. The first two projects use samples from two deep-sea cores, drilled during International Ocean Discovery Program (IODP) Expedition 355 “Arabian Sea Monsoon.” For my first project, I use strontium isotopes from pore waters to investigate diagenetic processes occurring in the cores. My second project focuses on reconstructing sediment provenance. I use the isotopic composition of strontium and neodymium in clays from the two sites to investigate the links between sediment provenance, monsoon variability, and tectonics over long time scales. For my final PhD project, I incorporate the marine barium cycle into the global oceanic carbon cycle model to gain more insight into the processes that control the ocean barium inventory, its spatial distribution, and its sensitivity to fluctuations.
