ABSTRACT A new approach and instrumentation for CO2 research will be developed. The proposed project will attempt to capture up to 70 tons of CO2 per day currently being emitted naturally into the Los Angeles Department of Public Works Mono Tunnel aqueduct which nms under the Inyo National forest. This CO2 is currently being vented to the atmosphere. The proposed work will lay the ground work for a truly long term CO2 experiment in mature, native pine forest in California. The proposed research will develop the necessary instrumentation and approaches to utilize a natural non-commercial source to provide the CO2 necessary for an extensive, replicated FACE (Free Air CO2 Enrichment on a natural forest. The proposed activities will develop the procedure and instrumentation necessary to collect and deliver the gas in a highly controlled manner using a FACE system within a native pine forest in the Inyo National Forest. Benefits of this research include expansion of FACE into a native forest setting, provision for a truly long term FACE experiment and establishment of links with other elevated CO2 experiments. It will contribute to a comprehensive assessment of CO2 effects on the ecosystems of the Western region of the United States.

一种新的CO2研究方法和仪器将被开发出来。拟议中的项目将尝试捕获目前每天自然排放到洛杉矶公共工程部的Mono隧道渡槽中的70吨二氧化碳，该渡槽位于Inyo国家森林之下。这些二氧化碳目前被排放到大气中。这项提议的工作将为在加利福尼亚成熟的原生松林中进行真正长期的二氧化碳实验奠定基础。拟议的研究将开发必要的仪器和方法，利用自然的非商业来源提供必要的二氧化碳，以便在天然森林上进行广泛的、可复制的FACE（自由空气二氧化碳富集）。拟议的活动将开发必要的程序和仪器，以便在Inyo国家森林的原生松林内使用FACE系统以高度控制的方式收集和输送天然气。这项研究的好处包括将FACE扩展到原生森林环境，提供真正长期的FACE实验，并与其他二氧化碳升高实验建立联系。它将有助于全面评估二氧化碳对美国西部地区生态系统的影响。
