Graduate Student position available at USF College of Marine Science, Florida
Masters in Chemical Oceanography at USF College of Marine Science
Project Description: Iron isotope cycling in a low-oxygen Fjord
Advisor: Dr. Tim Conway
Position to begin Fall 2018.
Iron is an essential micronutrient in biogeochemical systems, and in recent years iron isotopes have been used in order to constrain cycling and sources of iron to natural waters. Successful application of this tracer, especially in models of ocean biogeochemistry and for deep time reconstructions, requires a detailed understanding of how mechanisms such as anoxic-oxic cycling fractionate iron isotopes. This project thus aims to better understand the chemistry and fractionation of Fe isotopes across water-column anoxic-oxic transitions, making use of a water column time series collected from the Saanich Inlet, British Columbia over the winter-spring of 2016/2017, allowing investigation of seasonal cycling.
The student will measure Fe concentrations and isotopes in USF's new Tampa Bay Plasma Facility, which includes an ISO-6 Clean lab dedicated for seawater processing, a SeaFast system, Thermo HR-ICPMS Element XR and Thermo MC-ICPMS Neptune. The work will be interpreted in the context of the SaanDox project and will involve collaboration with other groups working on a large range of complementary parameters. There is also potential for extension to measure other redox-active isotope systems, modelling, and participate in other scientific cruises, as well as the opportunity to present work at international conferences.
Two years of funding and analysis costs are available for a Masters Student, and this project is ideal for a student interested in global biogeochemical cycling, isotope geochemistry and trace metals. Candidates must have or expect to have a strong undergraduate background in chemical, earth or physical science. Laboratory experience in geochemistry is desirable, but not required. We strongly encourage diverse applications and equal opportunities.
The USF College of Marine Science is located on the water in sunny St Petersburg, Florida, and hosts a vibrant community of graduate students and faculty undertaking world class research in a range of oceanographic disciplines.
