Research & Projects

Application and development of isotope and trace element geochemical proxies in an effort to further understand past and present-day processes at the Earth's surface. Some current research areas:

  • Variations in past rates of oceanic biological productivity and eolian fluxes and the relationship to past climate change
  • Changing patterns of deep-ocean sediment focusing and the relationship to changes in past ocean circulation and climate
  • Present-day and past riverine and eolian elemental fluxes to the oceans
