Paleoclimatology, Ocean Chemistry and Biochemistry

Research focuses on computational approaches to the interpretation of paleoclimate records; controls on the chemical composition of the oceans in the present and past; the reconstruction and understanding of

  • past monsoon rainfall variability,
  • temperature, salinity, and circulation of the oceans,
  • linkages between tropical oceans and high latitude climate, and their interaction with and effect on the monsoon systems and the biogeochemical cycling of organic material, methane, and hydrogen in microbially-dominated environments.



  1. 3D Virtual Reality System

    This system is currently being utilized for 3D visualization of ocean circulation.

  2. Gas Chromatograph

    Shimadzu GC-8A and Shimadzu GC-14A with custom automated sample extraction.

  3. Inductively Coupled Plasma Mass Spectrometer (ICP-MS)

    Used for high precision elemental ratios in carbonates and trace element determinations in seawater and marine organisms.

  4. Stable Isotope Ratio Mass Spectrometer (SIRMS)

    Used to study carbon and oxygen isotopes in carbonates.

  5. Valentine Group Equipment

    The Valentine Group Laboratory includes a variety of instruments and equipment.
