Research in Tim Conway鈥檚 group aims to understand the geochemistry of trace metals in the marine and earth system, and the role they play as micronutrients and/or toxins in marine biogeochemical cycles, with effects on the global carbon cycle. Researchers working and collaborating with Dr. Conway employs techniques including measurement of trace metal (Fe, Zn, Ni, Cd, Cu) isotope ratios and trace metal concentrations (Fe, Zn, Ni, Cd, Cu, Mn, Pb) in a range of materials including aerosol dust, rocks, sediments rain, seawater, ice-cores, marine particles and biological materials. Our group uses a Thermo Neptune Plus MC-ICPMS and an Element XR HR-ICPMS in the Tampa Bay Plasma Facility housed at CMS to shed new light on the biogeochemical cycling of trace metals in the modern ocean. We are also interested in developing and applying isotopic tracers as proxies for oceanic processes in the geological past.

Our group works closely with national and international collaborators as part of the International GEOTRACES program, working on seawater and other samples collected from all over the world. Currently, we have NSF-funded projects on trace metals and their isotopes in the North and South Pacific (US GEOTRACES sections GP15, GP17-OCE, GP17-ANT), nutrient cycling on the West Florida Shelf, and the dissolution of Fe from Atmospheric Dust. We also have ongoing research collaborations in the Arctic, South Atlantic, and Antarctic marginal seas.

We are always eager for collaboration in a range of marine and geologic fields, and are always looking for keen and motivated graduate students and postdocs. Please contact us for current opportunities.

Dr Conway is also an Associate Editor for Geochimica et Cosmochimica Acta, and sits on the International GEOTRACES Standards and Intercalibration Committee.
