My current research involves three principal areas of investigation: (1) the
speciation and behavior of trace metals in seawater, (2) investigation of marine and
riverine CO2 system chemistry and (3) development of in-situ procedures for observation
of the marine environment. My work on trace metals gives special emphasis to
investigations of the comparative chemistries of a variety of elements including platinum
and palladium, and yttrium plus the rare earths. Other enduring interests and current
research includes investigation of the aqueous behavior of iron, and the influence of
acantharia on the biogeochemistry of strontium and barium. Work on CO2 system chemistry
includes the development and oceanic application of novel systems for shipboard and
in-situ measurements of pH, total inorganic carbon, alkalinity, and CO2 fugacity.
Development of systems for in-situ measurements of metals, nutrients and CO2 system
variables involves close work with a variety of colleagues at the Center for Ocean
Technology (within the College of Marine Science). Previous cooperative work involving
COT engineers and CMS scientists has resulted in successful mass spectrometer
deployments/ observations in the upper ocean, and deployments of long pathlength
spectrometers for observation of oceanic nutrient distributions to depths of 200 meters.
