MRI: Acquisition of Gas fluxes and Analyzers to Strengthen Interdisciplinary Research and Education at Murray State University

默里州立大学(MSU)被授予研究气候变化对湿地和旱地生态系统温室气体(GHG)排放的影响。鉴于陆地温室气体生产和消费的气候重要性，该项目将通过监测和模型开发提高公众对保护当地环境的认识。该项目将改善密歇根州立大学的基础设施，为密歇根州立大学的学生进行多学科的研究、培训和教学。这一基础设施将允许密歇根州立大学的教职员工进行创新研究，并增加学生对尖端科学探究的参与。通过这项研究获得的系统将被整合到本科生和研究生课程的课程中，包括项目团队在地球、环境科学和生物系教授的6门课程，以加强每年100多名密歇根州立大学学生的培训和教学活动。购买设备将加强项目团队的能力，以吸引女性、第一代和代表性不足的学生进入该领域，并为他们提供机会，加强他们的研究技能，促进成功的未来科学家的发展。研究成果将通过当地农贸市场的网络互动活动和密歇根州立大学国家公共广播电台向公众传播，帮助公众了解碳循环。该项目支持的设备将允许实时分析温室气体交换的土壤-植被-大气，包括树冠二氧化碳(CO2)、水(H2O)和甲烷(CH4)，以及土壤二氧化碳、H2O、CH4和氮氧化物(N2O)。土壤中的二氧化碳、O2和CH4传感器与气体分析器系统位于同一位置，安装在不同的深度，可以深入了解产生或消耗温室气体的地下反应。这一集成系统将用于从植物生理学、生态学、气候变化到土壤-植被大气联合作用的研究项目。具体地说，该系统将用于解决与气候变化对湿地生态系统温室气体交换的影响、含氢土壤的土壤温室气体排放、树干CH4和N2O排放以及土壤温室气体浓度的变异性有关的问题。此次收购将使项目团队能够开展在密歇根州立大学不可能完成的尖端研究项目。它将提升学生的主动学习和研究体验以及教师的研究生产率。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

An award is made to Murray State University (MSU) to study the effects of changing climate on greenhouse gas (GHG) emissions in wetland and upland ecosystems. Given the climatic importance of the production and consumption of GHGs on land, this project will raise public awareness in protecting the local environment through monitoring and model development. The project will improve infrastructure at MSU for multidisciplinary research, training, and teaching of MSU students. This infrastructure will allow MSU faculty to conduct innovative research and increase student participation in cutting edge scientific inquiry. The system acquired through this research will be integrated into the curriculum for both undergraduate and graduate courses, including 6 courses being taught by the project team across the Earth and Environmental Sciences and Biology Departments, to provide enhanced training and teaching activities for more than 100 MSU students each year. The acquisition of the equipment will strengthen the project team abilities to attract women, first generation, and underrepresented students to the field and provide them with opportunities to strengthen their research skills and foster the development of successful future scientists. The research results will be disseminated to the public through web-based interactive activities in local farmer’s markets and MSU national public radio to help the public understand the carbon cycle.The equipment supported by this project will allow for real-time analysis of the soil-vegetation-atmosphere of GHGs exchanges including canopy carbon dioxide (CO2), water (H2O), and methane (CH4), and soil CO2, H2O, CH4, and nitrogen oxide (N2O). The soil CO2, O2, and CH4 sensors, co-located with gas analyzer systems and installed at different depths, yields insight into below ground reactions that produce or consume GHG. This integrated system will be used on research projects ranging from plant physiology, ecology, climate change to combined soil-vegetation atmosphere interactions. Specifically, the system will be used to address questions related to climate change effects on GHG exchange in a wetland ecosystem, soil greenhouse emissions in hydric soils, tree stem CH4 and N2O emissions, and variability of soil greenhouse gasses concentrations. The acquisition will allow the project team to conduct cutting-edge research projects that would be otherwise impossible at MSU. It will elevate student active learning and research experience and faculty research productivity.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
