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.

 

Instruments

  1. 3D Virtual Reality System »
    Campus Gov't/Academic Industry

    The 3D Virtual Reality System uses a 70" 3D TV in combination with motion tracking hardware and specialized visualization software developed by the  W. M. Keck Center for Active Visualization in the Earth Sciences at UC Davis. This system is currently being utilized for 3D visualization of ocean circulation.

  2. Gas Chromatograph »
    Campus Gov't/Academic Industry

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

  3. Inductively Coupled Plasma Mass Spectrometer »
    Campus Gov't/Academic Industry
    Finnigan Element2 High Resolution Double Focusing Sector ICP-MS used for high precision elemental ratios in carbonates and trace element determinations in seawater and marine organisms.
  4. Inductively Coupled Plasma Mass Spectrometer (ICP-MS) »
    Campus Gov't/Academic Industry

    Finnigan Element2 High Resolution Double Focusing Sector ICP-MS used for high precision elemental ratios in carbonates and trace element determinations in seawater and marine organisms.

    New Wave UP-213 UV laser (213 nm wavelength) for ablation sampling of solids at micron scale spatial resolution.

    The Element2 along with other analytical equipment (located in our Woodhouse Lab) is now managed by MSI as a recharge lab. There are numerous other analytical instruments managed by the Marine Science Institute that are generally available to researchers.

  5. Stable Isotope Ratio Mass Spectrometer (SIRMS) »
    Campus Gov't/Academic Industry

    Thermo MAT 253 coupled to Kiel IV (carbonate sample preparation devise), dual inlet analysis of CO2, and small sample capability (10 micron grams) is used to study carbon and oxygen isotopes in carbonates. For more information, surf to the Stable Isotope Lab.
