MRI: Acquisition of a gas source mass spectrometer and carbonate preparation device for applications in the geosciences

PI申请核磁共振基金，用于购买气源质谱仪和碳酸盐制备装置，用于地球科学。该仪器将用于支持地幔地球化学、古海洋学和古气候学以及体质人类学等项目。目前对该仪器的需求要求能够每年测量多达10,000个样品，主要以有孔虫，珊瑚粉，珐琅和斑晶CO2的形式。该仪器旨在取代老化的仪器，而不会造成灾难性的生产力损失，同时还可以测量目前被“外包”给其他实验室的小质量样品。更广泛的影响：该仪器将被放置在一个新重组的SIO同位素地球化学中心，这是一个更大的核心分析设施网络的一部分。加强对研究生和高级本科生的“动手”训练是该中心的一个重要目标。该仪器还将支持研究生和本科生的课堂教学，并将作为加强旨在增加科学多样性的现有项目的自然手段。“STARS”计划-科学研究暑期培训学院。该项目由美国国家科学基金会（NSF）资助，加州大学圣地亚哥分校（UCSD）管理，每年都将本科生从代表性不足的群体中安置到实验室环境中。拟议的文书将为该计划的参与者提供一个理想的平台。

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.
