A New CO2 Resource and Facility for Determination of the Effects of Elevated Atmospheric CO2 on Native Pinus Jeffreyi Forests Using Geothermal Sources of CO2: Development of ...

摘要 将为二氧化碳研究开发新的方法和仪器。拟议的项目将试图捕获高达70吨的二氧化碳，每天目前正在自然排放到洛杉矶公共工程部莫诺隧道渡槽，该渡槽位于Inyo国家森林之下。这些二氧化碳目前正在排放到大气中。这项工作将为在加州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，利用天然非商业来源提供广泛的、复制的FACE（天然森林的自由空气CO2富集）所需的CO2。拟议的活动将开发必要的程序和仪器，以便在Inyo国家森林的原生松树林内使用FACE系统以高度受控的方式收集和输送气体。 这项研究的好处包括扩展到一个原生森林设置的FACE，提供一个真正长期的FACE实验和建立与其他升高的CO2实验的联系。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。

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.
