Marine Metal Isotope and Trace Element Laboratory

Main Content

ABOUT US

We are a geochemical research group at the USF College of Marine Science, led by Assistant Professor Tim Conway. With a ISO-6 Clean Laboratory, an ESI SEAFAST system, and the USF Tampa Bay Plasma ICPMS Facility (Thermo Element XR and Neptune Plus) at CMS, we are well equipped to study the isotope geochemistry and biogeochemical cycling of trace-metals and other isotope systems in the ocean and earth systems. We are especially interested in the role of bioactive trace elements in biogeochemical cycles, and the application of new tracers to understanding the past.

We use isotopic techniques, including measurement of trace metal (Fe, Zn, Ni, Cd, Cu) isotope ratios by MC-ICPMS in a range of materials including aerosol dust, rain, seawater, sediments, pore waters, marine particles and biological materials. We work closely with local, national and international collaborators as part of the International GEOTRACES program, working on seawater and other geochemical samples collected from all over the world. Our current seawater focus is on the South Atlantic and North Pacific Oceans, but we have a number of ongoing collaborations in the Southern Ocean. We also have research interests in the Gulf of Mexico and the Gulf Stream, and are carrying out experimental work on the dissolution of iron from atmospheric dust.

MarMITE is looking for a MS/PhD student to begin Fall 2019! Apply via the CMS website. We are also always very eager for collaboration in a range of marine, chemical and geochemical fields.
