The PI requests MRI funding to acquire a gas source mass spectrometer and carbonate preparation device for applications in the geosciences. This instrument will be used to support projects in mantle geochemistry, paleoceanography and paleoclimatology, and physical anthropology. Current demand for this instrument requires the ability to measure up to 10,000 samples per year, primarily in the form of foraminifera, coral powder, enamel and phenocryst CO2. The proposed instrument is designed to replace the aging instrumentation without catastrophic loss of productivity, while also enabling the measurement of small mass samples that are currently being "outsourced" to other laboratories. Broader Impacts: The instrument will be placed in a newly reorganized SIO Center for Isotope Geochemistry - part of a larger network of core analytical facilities. Intensive "hands on" training of graduate students and advanced undergraduates is an essential goal of the center. The instrumentation would also support classroom instruction on graduate and undergraduate levels, and it would serve as a natural means for strengthening existing programs aimed at increasing diversity in science. The "STARS" program - Summer Training Academy for Research in the Sciences. Funded by NSF and administered through UCSD, this program each year looks to place undergraduates from underrepresented groups into laboratory environments. The proposed instrument would provide an ideal platform for participants in this program.

PI要求MRI资金以在地球科学中的应用中获取气源质谱仪和碳酸盐准备装置。该仪器将用于支持地幔地球化学，古环境学和古气候学和身体人类学的项目。当前对该仪器的需求需要每年最多测量10,000个样品，主要是以有孔虫，珊瑚粉，搪瓷和苯乙烯CO2的形式进行测量。该拟议的仪器旨在替代老化仪器，而不会造成灾难性的生产率损失，同时还可以测量目前正在“外包”到其他实验室的小型样本。更广泛的影响：该仪器将放置在新的重组的同位素地球化学中心 - 更大的核心分析设施网络的一部分。对研究生和高级本科生进行密集的“动手”培训是该中心的基本目标。该仪器还将支持有关毕业和本科级别的课堂教学，这将是加强旨在增加科学多样性的现有计划的自然手段。 “星星”计划 - 科学研究夏季培训学院。该计划每年由NSF资助并通过UCSD管理，旨在将来自代表性不足的群体的本科生纳入实验室环境。拟议的仪器将为该计划的参与者提供理想的平台。
