9817348KaufmanThis grant provides partial support for the purchase of a gas source stable isotope mass spectrometer with automated preparation systems for the Isotope Geochemistry Laboratory at the University of Maryland. The Principle Investigators include: A.Jay Kaufman, a recent addition to the Department of Geology faculty after seven years as a post-doctoral fellow and research scientist in stable isotope geochemistry at Harvard University; Karen Prestegaard, a physical and chemical hydrologist in the Department of Geology; and Margaret Palmer, an ecologist in the Department of Zoology. In addition, Christina Gallup, a geochronologist and coral researcher in the Department of Geology, and Russ Dickerson, an atmospheric chemist in the Department of Meteorology will use the new instrumentation in their studies.The establishment of a gas source stable isotope mass spectrometer at the University of Maryland represents the first academic facility of its kind in the Washington D.C. area. As such, this facility will allow additional collaborative studies by local researchers, in particular at George Washington University and the Smithsonian Institution. The gas source instrument will be housed in a newly-renovated laboratory adjacent to the existing stable isotope preparation laboratory in the Chemistry building. This facility, funded by the university and the Earth Sciences Instrumentation and Facilities Program (EAR/IF), will support research initiatives in chemical stratigraphy, carbonate geochemistry, global climatic and environmental change, coral research, hydrology, atmospheric and environmental sciences.***

9817348考夫曼这笔赠款为马里兰州大学同位素地球化学实验室购买一台带有自动制备系统的气源稳定同位素质谱仪提供部分支持。 主要研究人员包括：A.Jay考夫曼，最近加入地质系，在哈佛大学担任稳定同位素地球化学博士后研究员和研究科学家七年; Karen Prestegaard，地质系的物理和化学水文学家;和Margaret Palmer，动物学系的生态学家。此外，地质系地质年代学家和珊瑚研究员克里斯蒂娜盖洛普和气象系大气化学家拉斯迪克森将在他们的研究中使用新仪器。在马里兰州大学建立的气体源稳定同位素质谱仪是华盛顿地区第一个此类学术设施。 作为 因此，这一设施将使当地研究人员，特别是乔治华盛顿的研究人员能够进行更多的合作研究 大学 和 的 史密森学会。 气源仪器将安置在一个新装修的实验室内，该实验室毗邻化学楼内现有的稳定同位素制备实验室。该设施由该大学和地球科学仪器和设施计划（ESTA/IF）资助，将支持化学地层学，碳酸盐地球化学，全球气候和环境变化，珊瑚研究， 水文学， 大气和环境科学 *
