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

PI请求MRI资助，以获得气体源质谱仪和碳酸盐制备设备，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自然人类学等项目。目前对该仪器的需求要求每年能够测量多达10，000个样品，主要是有孔虫，珊瑚粉，搪瓷和斑晶CO2的形式。拟议的仪器旨在取代老化的仪器，而不会造成生产力的灾难性损失，同时还能够测量目前被“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-一个更大的核心分析设施网络的一部分。对研究生和高年级本科生进行密集的“动手”培训是该中心的一个基本目标。该仪器还将支持研究生和本科生的课堂教学，它将作为加强旨在增加科学多样性的现有计划的自然手段。 “STARS”方案-科学研究暑期培训学院。由NSF资助并通过UCSD管理，该计划每年都希望将来自代表性不足的群体的本科生置于实验室环境中。拟议的文书将为该方案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.
