Technician Support Phase II: Isotope Geochemistry Laboratory, Department of Geological Sciences, University of Washington

9803659纳尔逊这笔赠款在两年内为系内同位素地球化学实验室的技术支持提供50%的工资支持。华盛顿大学地质科学系。这笔赠款代表了第二阶段的技术人员支持，这是继第一阶段(EAR-9417870)提供的三年支持之后的第二阶段。同位素地球化学师G.Hinn现在在固体源质谱学、化学分离、酸蒸馏以及对实验室运行至关重要的电气和机械维护方面拥有8年的经验。他在U-Pb，Sm-ND，Rb-Sr同位素体系分析方面经验丰富，并协助开发了矿物和天然水中钙、镁、钾、钒、铀和钡的高精度微量元素分析。技术人员职责的一个关键方面是每天监测清洁实验室中工作人员的操作和遵守规程。他还参与对学生和访问研究人员的教育。例如，在第一阶段支持期间，他任教并一直是六名参与研究的本科生、六名研究生和两名博士后研究人员的持续资源。技术支助赠款支持的研究涉及范围广泛，但大部分研究遵循四个主要科学主题：大洋岛火山作用、大陆边缘的构造和岩浆作用、海洋中的现代和古化学通量以及环境中金属的迁移。与以往一样，通过广泛的合作，这笔赠款将支持同位素地球化学实验室，使其不仅成为地质科学领域的学生和同事的资源，而且也成为海洋学、化学和地球物理系以及西北地区其他大学和学院的同事的资源。***

9803659 Nelson This grant provides 50% salary support over two years for technical support in the Isotope Geochemistry Laboratory in the Dept. of Geological Sciences, University of Washington. This grant represents Phase II of technician support which follows on three years support provided by Phase I (EAR-9417870). The isotope geochemistry technician, G. Hinn, now has eight years of experience in solid-source mass spectrometry, chemical separations, acid distillation, and electrical and mechanical maintenance critical to operation of the laboratory. He is experienced in the anlayses of U-Pb, Sm-Nd, Rb-Sr isotope systems, and has assisted in development of high-precision trace element analyses of Ca, Mg, K, V, U and Ba in minerals and natural waters. A critical aspect of the technician's duties is to monitor on a daily basis operation and adherence to protocol by workers in the clean labs. He also participates in the education of students and visiting researchers. For example, during Phase I support, he taught and was a constant resource for six undergraduate students who have been involved in research, six graduate students and two post-doctoral researchers. Research supported by the technical support grant spans a large range of subjects but much of it follows four main scientific themes; ocean island volcanism, tectonics and magmatism at continental margins, modern and paleo-chemical fluxes in the oceans, and migration of metals in the environment. As in the past, through extensive collaborative work this grant will support the Isotope Geochemistry Lab as a resource for students and colleagues not only in Geological Sciences, but also in Departments of Oceanography, Chemistry and Geophysics, and for colleagues at other universities and colleges in the northwest. ***
