Graduate Student Position available
at University of South Florida College of Marine Science

Project Area: Chemical Oceanography - Iron isotope biogeochemistry (MarMITE group)
Advisor: Dr. Tim Conway
Start Date: Spring or Fall 2019 (deadline for applications Jan 15th 2019).

The MarMITE group at USF 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. 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 seeking a highly motivated graduate student (PhD or MS) to join our group at USF.

Project Focus: Investigating how iron is released from atmospheric desert dust in the oceans. The student will investigate how isotopic tracers can be used to better understand the chemistry of desert dust and how iron becomes available for phytoplankton once it enters the surface 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.

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. This project involves funded fieldwork at Bermuda and in the Gulf of Mexico, and there will be opportunities for 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.
