Technical Support for the Stable Isotope Facility at the GL at UMCP

这笔赠款将用于资助一名全职实验室技术员，他将在马里兰州大学地球化学实验室新翻修的稳定同位素设施工作（http：//www.geol.umd.edu/tagjfarquha/stable_isotope_lab.htm）。 实验室技术员将主要负责质谱分析设施。 其他职责将包括监督样品制备设施的日常运作，监督访客，博士后研究员和使用该设施的学生，以及开发，改进和应用新的分析技术。 该设施目前有四台质谱仪，由两名主要研究人员监督。在稳定同位素设施进行的地球化学调查涉及广泛的研究课题，包括： 地球最早的硫和碳循环; 光化学和大气研究; 地壳和地幔的研究; 陨石研究; 元古宙冰期旋回; 二叠纪-三叠纪的灭绝与恢复; 水文过程;以及 生态学研究。所有正在进行的项目都需要一套多功能的质量分析仪和进气系统，以及一名技术人员的全职协调和监督。 在这个角色中，技术人员将有助于该设施的科学，并预计将有助于培训和教学的学生和其他用户从内外的马里兰州边界的大学，包括利用实验室的课程活动。

EAR-0345612FarquharThis grant will support a full time laboratory technician who will work in the newly renovated Stable Isotope Facility of the Geochemistry Laboratories at the University of Maryland (http://www.geol.umd.edu/~jfarquha/stable_isotope_lab.htm). The laboratory technician will be primarily responsible for the mass spectrometry facility. Other responsibilities will include overseeing the day-to-day operation of sample preparation facilities, supervising visitors, post doctoral fellows, and students using the facility, and for the development, refinement, and application of new analytical techniques. This facility presently houses four mass spectrometers and is overseen by two principal investigators. Geochemical investigations undertaken in the Stable Isotope Facility span a wide range of research topics, including: Earth's earliest sulfur and carbon cycles; Photochemical and atmospheric studies; Studies of the Earth.s crust and mantle; Studies of meteorites; Proterozoic glacial cycles; Permo-Triassic extinction and recovery; Hydrologic processes; and Ecological studies. All of there on-going projects require a versatile set of mass analyzers and inlet systems, and the full-time coordination and oversight of a technical officer. In this role, the technician will contribute to the science of the facility, and be expected to contribute to the training and teaching of students and other users from within and beyond University of Maryland boundaries, including course activities that utilize the laboratories.
