MRI: Acquisition of instrumentation to study stable isotopes of the carbon, nitrogen, and water biogeochemical cycles.

华盛顿州立大学(WSU)已收到重大研究仪器计划的资金，用于支持购买可调谐二极管激光光学分析仪(TGA100A)、树叶气体交换系统(LI6400)、十探测器同位素比质谱仪和同位素水分析仪(L1102-I)。该仪器将被并入华盛顿州立大学的生物技术和生物分析实验室2(LBB2)稳定同位素核心设施。通过环境研究、教育和推广中心(CEREO)，这一工具将促进在全球气候变化和整个大学的碳、氮和水的生态系统-大气交换领域的研究和培训。TGA100A和LI6400将用于在生态系统和树叶水平上测量大气和生物圈之间的微量气体交换。质谱仪的重点将是确定农业和自然环境中氮污染物和化肥的来源。L1102-I将用于研究植物和土壤剖面中的水分运动，并了解这些过程如何受到气候变化的影响。此外，该仪器将被纳入几门研究生和本科课程，并将成为通过NSF资助的综合研究生教育和研究培训(IGERT)赠款开发的氮气方法研讨会的组成部分。还将通过稳定的同位素核心设施提供实习机会，对来自区域大学的人数不足的本科生和研究生进行关于这一仪器的技术方面的培训，并让高中生参与独立研究项目。

Washington State University (WSU) has received funds from the Major Research Instrumentation Program to support the acquisition of a tunable diode laser optical analyzer (TGA100A), a leaf gas exchange system (LI6400), a ten detector isotope-ratio mass spectrometer, and an isotopic water analyzer (L1102-i). The instrumentation will be incorporated into WSU's Laboratory for Biotechnology and Bioanalysis 2 (LBB2) Stable Isotope Core facility. Through the Center for Environmental Research, Education and Outreach (CEREO) this instrumentation will facilitate research and training in the area of global climate change and ecosystem-atmosphere exchange of carbon, nitrogen and water across the University. The TGA100A and LI6400 will be used to measure the exchange of trace gases between the atmosphere and the biosphere at ecosystem and leaf levels. The focus of the mass spectrometer will be to identify sources of nitrogen pollutants and fertilizers in agricultural and natural environments. The L1102-i will be used to study water movement through plants and soil profiles, and to understand how these processes are affected by changing climate. Additionally, the instrumentation will be incorporated into several graduate and undergraduate courses and will be an integral part of a nitrogen methods workshop developed through a NSF funded Integrative Graduate Education and Research Traineeship (IGERT) grant. An internship through the Stable Isotopes Core facilities will also be available to train underrepresented undergraduate and graduate students from regional Universities on the technical aspects of this instrumentation and to engage high school students in independent research projects.
