This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This Major Research Instrumentation-Recovery and Reinvestment (MRI-R2) award funds the acquisition of a stable isotope ratio mass spectrometer with an elemental analyzer interface at Southern Oregon University (SOU). The instrumentation provides a powerful tool for understanding the fluxes of water, carbon and nitrogen though biological systems. Stable isotope analysis has permeated most sub-disciplines in biology, chemistry, geology as well as environmental and forensic science. Faculty and students are increasingly utilizing isotopic concepts and applications in both research and teaching. The instrument serves as both a pedagogical tool and a resource for research projects than span many disciplines. With access to this instrument, local scientists explore innovative new projects and obtain preliminary data that enhances research infrastructure and prospects for competitive funding. SOU has a strong commitment to teaching excellence. All scientific instrumentation is available for use in instruction. Students learn about stable isotopes in lecture and are able to enhance their understanding of this complex topic through active-learning exercises and hands-on research experiences. Acquisition of this technology enhances the instrumentation infrastructure at SOU for both the Biology and Chemistry departments and provides students with a powerful tool that can be utilized in senior independent research projects. Some of the potential projects listed above could benefit society through an increased understanding of climate variability and change, forensic applications that enhance criminal investigations and a greater appreciation for environmental issues facing aquatic and forest ecosystems. Results from the studies enabled by the new equipment will be disseminated by student and faculty presentations at regional and national meetings, and through publication in peer-reviewed journals.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该主要研究仪器-回收和再投资（MRI-R2）奖资助南俄勒冈州大学（SOU）购买一台带有元素分析仪接口的稳定同位素比质谱仪。 该仪器为了解水、碳和氮通过生物系统的通量提供了有力的工具。稳定同位素分析已经渗透到生物学、化学、地质学以及环境和法医学的大多数分支学科。教师和学生越来越多地利用同位素的概念和应用在研究和教学。该工具既是一种教学工具，也是跨越许多学科的研究项目的资源。有了这一工具，当地科学家可以探索创新的新项目，并获得初步数据，以加强研究基础设施和竞争性资金的前景。 SOU有一个强大的承诺，教学卓越。 所有科学仪器都可用于教学。学生在讲座中了解稳定同位素，并能够通过积极的学习练习和实践研究经验来提高他们对这个复杂主题的理解。该技术的收购增强了SOU的生物和化学部门的仪器基础设施，并为学生提供了一个强大的工具，可以在高级独立研究项目中使用。上面列出的一些潜在项目可以通过加深对气候变异性和变化的了解、加强刑事调查的法医应用以及更好地了解水生和森林生态系统面临的环境问题来造福社会。 新设备所带来的研究结果将通过学生和教师在区域和国家会议上的介绍以及在同行评审期刊上发表来传播。
