MRI: Acquisition of Off-Axis Integrated-Cavity Output Spectroscopy Instruments for Ecological Research and Training at Northern Arizona University

在George Koch博士的指导下，北亚利桑那大学获得了一项用于生态分析系统的仪器，用于测量各种现场的各种形式的碳和水蒸气。将建造一个移动住房，使他们能够根据不同的环境条件将仪器运送到不同的地点。他们将测量的碳同位素的类型和数量使他们能够测试由于真菌和微生物分解过程而导致的碳在土壤中积累的假设，确定溪流食物网中碳的来源，并测试与数千年来气候变化有关的想法。调查人员将把这些仪器整合到他们的课程和学生的研究培训中。这所大学有大量的西班牙裔和美国原住民学生，新的仪器将被纳入这些学生的研究体验中。研究生参与当地学校和公众的教育活动，新的工具将加强这些外展努力。

An award has been made to Northern Arizona University under the direction of Dr. George Koch to acquire an instrument for ecological analysis system for the measurement of various forms of carbon and water vapor in a variety of field sites. A mobile housing will be built to allow them to transport the instrument into locations subject to different environmental conditions. The types and amounts of carbon isotopes that they will measure allow them to test hypotheses on the way carbon accumulates in soils due to fungal and microbial processes of decomposition, to determine the source of carbon in stream food webs, and to test ideas relating to climate change over thousands of years. The investigators will integrate the instruments into their courses and research training for students. The university has a significant Hispanic and Native American student population, and the new instrumentation will be incorporated into research experiences for these students. Graduate students participate in educational activities for local schools and the general public, and the new instrumentation will enhance these outreach efforts.
