1560664YoungThis 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. ***

1560664young这笔拨款支持购置一台稳定同位素比质谱仪（SIRMS），专门用于硫同位素比的分析。从拟议的SIRMS中立即受益的具体研究包括古代海洋的古氧化还原条件、海洋食物网动态以及硫酸盐还原微生物与甲基汞生产之间的联系。该仪器将被安置在nsf支持的FSU国家高磁场实验室（NHMFL）中，该实验室使FSU的学生，教职员工和研究人员以及来自其他大学和周边社区的众多访问科学家受益。除了对学生进行用于古记录研究的稳定同位素分析方法的培训外，研究人员还计划利用该仪器在当地进行K-12推广。鉴于学生在地球化学和化学分析技术方面的培训对支持未来科学劳动力需求的重要性，这种支持与国家科学基金促进科学进步和促进国家福利的使命是一致的。＊＊＊
