We are a geochemical research group at the USF College of Marine Science, led by Associate Professor Tim Conway. We study trace metals in the oceans, especially the role these metals play as nutrients and toxins for phytoplankton and their importance in driving marine primary productivity and carbon cycling. We are especially interested in the way these metals enter and leave the ocean. To do this, we measure trace metal concentrations (Fe, Zn, Cd, Mn, Pb, Ni, Cu) and isotope ratios (Fe, Zn, Cd) in a range of samples. 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 spans the North Pacific to the Southern to the North Atlantic Oceans. We also have research interests in the Gulf of Mexico, and are carrying out experimental work on the dissolution of iron from atmospheric dust.
We are also always very eager for collaboration in a range of marine, chemical and geochemical fields. If you are interested in joining our group at USF, please get in touch.
