Education:
BS, Massachusetts Institute of Technology (Environmental Science), 1974
MS, California Institute of Technology (Civil Engineering/Water Resources), 1975
PhD, Woods Hole Oceanographic Institution (Chemical Oceanography), 1981
Research Interests:
Trace element geochemistry of dissolved and particulate materials in the marine environment; processes controlling elemental fluxes at major marine interfaces/estuaries; surface waters; sediments; suspended particles; ridgecrest hydrothermal systems; nutrient and trace metal cycles in fresh water environments.
Current Research:
Trace metal chemistry in evolved hydrothermal plumes; geochemistry and limnology of Crater Lake, Oregon; chemistry of steeling biogenic materials and the preservation of tracers of this material in the sediment record; sources and fate of methane associated with hydrates on the Oregon margin.
Paleochemistry of V, Mo, and other seawater oxyanions recorded in ferromanganese deposits.
Relationships between hydrothermal plumes and sampled vents on a super-fast spreading center: the southern East Pacific Rise.
Elemental tracers as proxies of productivity and environmental setting of the Southern Ocean.
Chemical distributions and fluxes in the water column above an emerging hydrate field ...TECFLUX.
