Research Interests

My interest is to answer the principal question: What is the time and cause of the mode shift from the interbasinal Paleogene mode of ocean overturning circulation to the modern MOC mode? My Masters project will work toward answering this question by evaluating the following hypotheses using IODP sediment cores:

  • The loss of bipolar convection in the Pacific will manifest as a divergence of εNd in deep-water sites compared to shallower sites. (As the mode shift occurred to a more global overturning circulation Southern Ocean deep-water began to dominate the deep sites.)
  • The North Pacific will demonstrate a shift in εNd from relatively radiogenic to relatively unradiogenic as the mode shift occurs.
