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.

EAR-0345612Farquhar 这笔赠款将支持一名全职实验室技术员，他将在马里兰大学地球化学实验室新装修的稳定同位素设施中工作 (http://www.geol.umd.edu/~jfarquha/stable_isotope_lab.htm) 。 实验室技术员将主要负责质谱设施。 其他职责包括监督样品制备设施的日常运行，监督使用该设施的访客、博士后研究员和学生，以及新分析技术的开发、完善和应用。 该设施目前拥有四台质谱仪，并由两名主要研究人员负责监督。稳定同位素设施进行的地球化学研究涵盖了广泛的研究主题，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； 元古代冰川循环； 二叠纪-三叠纪灭绝和恢复； 水文过程；和生态研究。所有正在进行的项目都需要一套多功能的质量分析仪和入口系统，以及技术官员的全职协调和监督。 在此职位上，技术人员将为设施的科学做出贡献，并有望为马里兰大学内外的学生和其他用户的培训和教学做出贡献，包括利用实验室的课程活动。
