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 CMS Ocean Technology Group (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.
