EAR-0317825GarizoneThis grant will be used to purchase a gas source isotope ratio mass spectrometer (IRMS) for analysis of O and H isotopes in water; O and C isotopes in carbonate, dissolved inorganic carbon, and CO2 gas; and C and N isotopes in organic matter. Primary users of this equipment will be the faculty, students, and visiting researchers in the Department of Earth and Environmental Sciences at the University of Rochester. This equipment will help us meet our research and teaching needs in the geological and environmental sciences, while continuing to develop strengths in geochemistry and tectonics. Stable isotope techniques are fundamental to paleoenvironmental studies. Understanding paleoclimate, paleoaltitude, and/or paleovegetation in the context of the tectonic evolution of mountain belts (P.I.'s main research focus) will potentially yield great advances in our understanding of the impacts of tectonics on regional and global climate. The proposed equipment will provide a wide range of applications enabling the analysis of carbonate, organic matter, water and gas samples essential to studies of ancient and modern environment, mantle processes, biological processes, and paleoceanography. The broader impacts of this proposal are that acquisition of an IRMS will greatly enhance undergraduate, graduate, and post-doctoral education at the University of Rochester by enabling students to get training on equipment that is widely used within the geological and environmental sciences. This proposal is part of a departmental effort that emphasizes undergraduate/graduate-level laboratory based instruction and independent research. In the courses that are taught within the Department of Earth and Environmental Sciences there is a strong emphasis on stable isotope applications in the geological and environmental sciences. There is an additional course on Analytical Methods in Geochemistry, which gives both undergraduate and graduate students hands-on training on existing equipment within the department, enabling them to use the equipment to collect their own data for senior thesis or graduate research projects.

这笔赠款将用于购买一台气源同位素比质谱仪（IRMS），用于分析水中的O和H同位素;碳酸盐、溶解无机碳和CO2气体中的O和C同位素;以及有机物中的C和N同位素。 该设备的主要用户将是罗切斯特大学地球与环境科学系的教师、学生和访问研究人员。 这些设备将帮助我们满足地质和环境科学的研究和教学需求，同时继续发展地球化学和构造学的优势。 稳定同位素技术是古环境研究的基础。 了解古气候，古海拔，和/或古植被的背景下，构造演化的山区带（P.I.的主要研究重点）将可能在我们对构造对区域和全球气候影响的理解方面产生巨大的进步。 拟议的设备将提供广泛的应用，使碳酸盐，有机物，水和气体样品的分析至关重要的古代和现代环境，地幔过程，生物过程和古海洋学的研究。 这一建议的更广泛的影响是，IRMS的收购将大大提高本科生，研究生和博士后教育在罗切斯特大学，使学生能够得到广泛使用的设备在地质和环境科学的培训。 该提案是强调本科生/研究生水平的实验室教学和独立研究的部门努力的一部分。 在地球与环境科学系教授的课程中，非常强调稳定同位素在地质和环境科学中的应用。 还有一个额外的地球化学分析方法课程，为本科生和研究生提供部门内现有设备的实践培训，使他们能够使用设备收集自己的数据用于高级论文或研究生研究项目。
