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

在乔治科赫博士的指导下，向北方亚利桑那大学颁发了一项合同，以获得一种生态分析系统仪器，用于测量各种实地的各种形式的碳和水蒸气。 将建造一个移动的外壳，使他们能够将仪器运送到不同环境条件下的地点。 他们将测量的碳同位素的类型和数量使他们能够测试关于真菌和微生物分解过程导致碳在土壤中积累的方式的假设，以确定河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。 研究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。 该大学有一个显着的西班牙裔和美洲原住民的学生群体，新的仪器将被纳入这些学生的研究经验。 研究生参加当地学校和公众的教育活动，新的仪器将加强这些推广工作。

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.
