Facility Support: Northeast National Ion Microprobe Facility at the Woods Hole Oceanographic Institution

0422965Peucker-Ehrenbrink该项目为世界卫生组织东北国家离子微探测器设施(NENIMF)提供2005年和2006年的业务支持。Cameca IMS3f将是2005年唯一可用于分析工作的仪器，而修复后的IMS1270可能在2006年下半年可用。IMS3f被广泛而多样的内部和外部用户群体使用，并为地球化学界提供了访问小型离子微探针的途径。科学优先事项包括：(A)对来自各种大地构造环境的矿物、玻璃和单个熔体包裹体进行微量元素分析；(B)对生物碳酸盐骨架中的主要元素和微量元素进行分析，以恢复过去地质上的海洋表面温度；(C)对实验药包中的微量元素进行分析，以校准熔体-矿物和海水-矿物分配系数。设施人员将继续向学生、博士后和客座科学家介绍离子微探针技术，并协助他们的分析工作。设施人员将通过出版物、在国内和国际会议上的正式陈述、为新用户举办的短期课程以及通过与其他离子微探头设施的非正式接触，参与传播离子微探针技术和新的分析进展。

0422965Peucker-EhrenbrinkThe Project provides operational support for the Northeast National Ion Microprobe Facility (NENIMF) at WHOI for the years 2005 and 2006. The Cameca IMS 3f will be the sole instrument available for analytical work in 2005, whereas the restored IMS 1270 may be available in the latter half of 2006. The IMS 3f is used by a broad and diverse group of in-house and external users, and provides the geochemical community with access to a small format ion microprobe. The scientific priorities include (a) trace element analyses of minerals, glasses and individual melt inclusions from a variety of geotectonic settings, (b) major and trace element analyses in biogenic carbonate skeletons aimed at reconstructing sea surface temperatures in the geologic past as well as (c) trace element analyses in experimental charges aimed at calibrating melt-mineral and seawater-mineral partition coefficients. Facility personnel will continue to introduce students, post-docs and guest scientists to ion microprobe technology and assist with their analytical work. Facility personnel will participate in the dissemination of ion microprobe technology and new analytical developments through publications, formal presentations at national and international meetings, short courses for new users, and through less formal contacts with other ion microprobe facilities.***
