Acquisition of a Stable Isotope Ratio Mass Spectrometer for Global Change Research at USF

9816650昆赛基金会资助南佛罗里达大学为全球变化研究购置稳定同位素比质谱仪（SIRMS）的部分费用。 Co-PI，Quinn和Flower将使用质谱仪生成高分辨率稳定的氧和碳同位素记录，主要来自珊瑚和有孔虫碳酸盐，作为古海面温度，古生产力和过去大气pCO 2条件的代理全球气候变化研究。 南佛罗里达大学新的轻稳定同位素设施将对南佛罗里达大学的教职员工、学生和大坦帕湾地区的其他研究人员带来许多好处。 其中一些好处包括：1）帮助进一步建立古气候学，沉积地球化学和古海洋学的生产计划，2）允许USF教师和学生探索稳定同位素地球化学的新研究，3）允许与地球和海洋科学以外的同事扩大跨学科合作，以及4）促进本科生和研究生融入基于分析的研究项目。 SIRMS将安置在一个新装修的空间，专门为这种设施及其相关的样品制备室设计。 该补助金由地球科学仪器和设施计划（ESTA/IF），海洋科学部海洋仪器和技术服务计划（OCE/ITS）和大气科学部古气候计划（ATM/PC）平均分配。

9816650QuinnThis grant provides partial support of the costs of acquiring a stable isotope ratio mass spectrometer (SIRMS) for global change research at the University of South Florida (USF). Co-PIs, Quinn and Flower will use the mass spectrometer to generate high-resolution stable oxygen and carbon isotopic records, primarily from coralline and foraminiferal carbonate, as proxies of paleo sea-surface temperatures, paleoproductivity and past atmospheric pCO2 conditions in studies of global climate change. The new light stable isotope facility at USF will have numerous benefits to USF faculty, students and other researchers in the greater Tampa Bay area. Some of these benefits include: 1) helping to further establish a productive program in paleoclimatology, sedimentary geochemistry and paleoceanography, 2) permitting the exploration of new research in stable isotope geochemistry by USF faculty and students, 3) allowing the expansion of interdisciplinary collaboration with colleagues outside of the Earth and Marine Sciences, and 4) facilitating the integratioin of undergraduate and graduate students into analytically based research projects. The SIRMS will be housed in a newly renovated space specifically designed for such a facility and its associated sample preparation rooms. Support for this grant is shared equally between the Earth Science Instrumentation and Facilities Program (EAR/IF), the Division of Ocean Sciences' Oceanographic Instrumentation and Technical Services Program (OCE/ITS) and the Paleoclimate Program of the Division of Atmospheric Sciences (ATM/PC).***
