ABSTRACT
1560664
Young
This grant supports acquisition of a stable isotope ratio mass spectrometer (SIRMS) dedicated to the analysis of sulfur isotope ratios. Specific research that would immediately benefit from the proposed SIRMS includes study of paleo-redox conditions in ancient oceans, marine food web dynamics, and linkages between sulfate-reducing microbes with production of methyl-mercury.
The instrument would be housed in the NSF-supported FSU National High Magnetic Field Laboratory (NHMFL) that benefits students, faculty members, and researchers across FSU as well as numerous visiting scientists from other universities and the surrounding community. In addition to student training in methods of stable isotopic analysis as applied to paleorecords research the investigators plan local K-12 outreach utilizing the instrument. This support is congruent with NSFs mission of promoting the progress of science and advancing the national welfare given the importance of student training in analytical techniques in geochemistry and chemistry to support future scientific workforce needs.

PROJECT OUTCOMES REPORT
Disclaimer
This Project Outcomes Report for the General Public is displayed verbatim as submitted by the Principal Investigator (PI) for this award. Any opinions, findings, and conclusions or recommendations expressed in this Report are those of the PI and do not necessarily reflect the views of the National Science Foundation; NSF has not approved or endorsed its content.
The intellectual merits of this project were addressed by the following outcomes: A Thermo Delta V Plus isotope ratio mass spectrometer (IRMS) with an EA-Isolink peripheral device was purchased and installed in the National High Magnetic Field Laboratory (NHMFL) at Florida State University during the course of this award. The IRMS system has been dedicated to sulfur isotopic (δ34S) measurements at FSU and was stringently calibrated using using commercially available sulfur compounds and international sulfur isotope standards (IAEA S-1, S-2, S-3, and NBS-127). After the IRMS system met or exceeded all factory calibration and performance standards multiple internal FSU sulfur isotope laboratory standards were developed in PI-Young's lab using reagents and pure mineral materials. These internal FSU δ34S standards were rigorously calibrated using the IAEA/NIST standards purchased from this award. The last major sets of δ34S analyses done during the award period were on geologic and natural waters research samples from the PI's ongoing research investigations. These δ34S analyses on research materials are part of four graduate students theses and dissertation projects ( 3-MSc.; 1-PhD). These δ34S analyses are major components of manuscripts in preparation at this time to be submitted to peer-reviewed journals in the Earth Sciences. These manuscripts are from research investigations of early Paleozoic climatic, oceanographic, biotic change events to elucidate the linkages of marine redox conditions and changes in the long-term carbon and oxygen cycles.
The broader impacts of this project were addressed by the following outcomes: This new instrumentation the NHMFL has provided numerous training/professional development opportunities to all PI's involved (4-faculty members), one research technician, four graduate students, and one undergraduate student. Three graduate students and one undergraduate student working with PI-Young will be presenting research findings at the national Geological Society of America meeting in Seattle, WA this year. δ34S analyses carried out on this new instrumentation at FSU are major components of all these student presentations. This instrumentation has allowed students, faculty, and science support staff within the department of Earth, Ocean & Atmospheric Science at FSU to expand their hands-on skill sets with very specialized state of the art instrumentation that will help better prepare them for careers in industry and academia. Additionally, this instrumentation has allowed current students and faculty to expand their cutting-edge research. This instrumentation has enhanced the already significant facilities within the geochemistry program at FSU by adding a powerful tool to investigate research questions revolving around the modern and ancient cycling of a critical element on Earth, sulfur.
