Request for a Technical Associate to Support the Isotope Geochemistry Laboratories at the University of Rochester-Phase II

0132389 basu这笔拨款将继续为一名技术人员提供部分工资支持，以监督罗切斯特大学同位素地球化学设施的运行和维护。这是第二阶段的技术支持拨款，并遵循三年的初始NSF支持（EAR-9730743）。罗彻斯特的同位素地球化学设施拥有4台质谱仪，包括一台热电离质谱仪（TIMS）、一台多收集器电感耦合等离子体质谱仪（MC-ICP-MS）、一台基于四极体的ICP-MS和一台惰性气体质谱仪。这些仪器被Basu， Anbar和Poreda教授用于研究项目，从研究洪水玄武岩的岩石成因到研究矿物风化过程中重金属同位素的生物分馏，再到研究地质时期宇宙尘埃对地球表面的通量。该技术人员支持的仪器将继续为大学和一些合作的地球科学家提供有价值的研究和教育工具。由于该大学承诺在第二阶段奖励之后为该职位提供全职支持，NSF的支持有助于在地球科学领域创建一个由大学资助的工作，这是传统学术职业道路的另一种选择。＊＊＊

0132389BasuFunds from this grant provide continued partial salary support for a technician to oversee operation and maintenance of the isotope geochemistry facility at the University of Rochester. This is a Phase II technician support grant and follows three years of initial NSF support (EAR-9730743). The isotope geochemistry facility at Rochester houses four mass spectrometers including a thermal ionization mass spectrometer (TIMS), a multicollector inductively coupled plasma mass spectrometer (MC-ICP-MS), a quadrapole based ICP-MS and a noble gas mass spectrometer. These instruments are use by faculty members Basu, Anbar and Poreda for research projects ranging from studies of the petrogenesis of flood basalts to investigations of biological fractionation of heavy metal isotopes during mineral weathering to studies of cosmic dust fluxes to the surface of the earth over geologic time. The instruments supported by this technician will continue to provide a valuable research and educational tool to the University and to a number of collaborating geoscientists. As the University has committed to picking up full time support for this position following this Phase II award, NSF support has aided in the creation of an university funded job in the geosciences field that is an alternative to traditional academic career paths. ***
