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.***

9817348KAUFMANTHIS GRANT为购买气体源稳定同位素质谱仪提供了部分支持，并为马里兰州大学的同位素地球化学实验室提供了自动制备系统。 主要调查人员包括：A.Jay Kaufman，在哈佛大学的稳定同位素地球化学担任博士后研究员和研究科学家七年后，最近担任地质学系的新成员； Karen Prestegaard，地质系的物理和化学水文学家； 和动物学系的生态学家玛格丽特·帕尔默（Margaret Palmer）。此外，地质学系的地球教徒和珊瑚研究人员克里斯蒂娜·盖洛普（Christina Gallup）和气象学系的大气化学家拉斯·迪克森（Russ Dickerson）将在其研究中使用新仪器。建立了马里兰大学的气源稳定同位素质谱仪，代表了华盛顿州华盛顿特区的第一个学术机构。 因此，该设施将允许当地研究人员，尤其是乔治华盛顿大学和史密森尼机构的其他合作研究。 气源仪器将安置在化学大楼现有稳定同位素制备实验室附近的新近装修的实验室中。该设施由大学和地球科学仪器和设施计划（EAR/if）资助，将支持化学地层，碳酸盐地球化学，全球气候和环境变化，珊瑚研究，水文学，大气和环境科学的研究计划。***
