MS/PhD Position available in Chemical Oceanography at USF College of Marine Science to begin Fall or Spring 2019
Project Area: Iron isotope biogeochemistry (MarMITE group)
Advisor: Dr. Tim Conway
The MarMITE group at the University of South Florida focuses on using trace metal isotope tracers in order to better understand the integral role of trace metals in modern carbon cycling and biogeochemical cycles. We also focus on how we can use these tracers to better understand the ocean system in the geological past and future climate. Iron is perhaps the most important of these metals and is an essential micronutrient in biogeochemical systems. In recent years iron isotopes have been used in order to constrain cycling and sources of iron to natural waters, including the ocean. We are looking for a highly motivated graduate student (PhD or MS) to join our group at USF, focusing one one of the projects below:
1) Investigating how Fe is released from atmospheric dust in the oceans. This NSF-funded project in collaboration with Oregon State will involve experimental lab work and field studies investigating the mechanisms by which different organic molecules enhance dissolution of metals from dust in seawater. This project involves funded fieldwork at Bermuda and in the Gulf of Mexico.
2) Sources, cycling and sinks of Fe throughout the oceans. This project will make use of samples from GEOTRACES section cruises from different areas of the Pacific and Atlantic to further our understanding of how Fe enters the oceans from sediments, hydrothermal vents and atmospheric dust in these regions. Future cruise participation is possible.
The student will measure trace metal 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. Candidates must have a strong undergraduate background in chemical, earth or physical science. Laboratory experience in geochemistry is desirable, but not required.
A minimum of 2 years of salary+tuition is available, with opportunities for extension through a wide range of college endowed fellowships or further grant funding, and research costs for the projects are fully funded. There will be opportunities for local and international cruises, and to present at national and international conferences.
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.
