Acquisition of Equipment Cluster to Srengthen a Multi-Disciplinary Regional Biogeochemistry Core Facilty for Research and Training

该奖项将提供一组设备，以加强新建立的生物地球化学核心设施(BCF)。该设备群由四台核心设备和两台辅助仪器组成。在四个核心设备中，营养分析仪将用于水样的高通量营养采样；原位多探头将对水生态系统中的营养物质、溶解氧、叶绿素和pH进行实时同步分析；多通道O2/CO2呼吸仪将用于机械性生物地球化学研究，微生物分析系统将用于微生物群落动态研究。此外，两个气候控制的孵化器将与呼吸仪一起使用；两台计算机与呼吸仪和多探头仪器专用和集成使用。营养物分析仪和多探头有助于监测和记录水生生态系统中营养物浓度的变化，呼吸仪和微生物分析系统将提供对调节这些生态系统中营养物浓度的生物地球化学过程的洞察。这些仪器将立即用于一个跨学科项目，该项目旨在解决多种应激源对夏延河生态的影响。黑山历史上的黄金开采活动、黑山地区人口密度的增加以及煤层气(CBM)开采活动的发展，对夏延河的水质、资源供应和生态产生了不利影响。该奖项将促进将生态系统科学和自然资源管理相结合的关于水质和生物地球化学的多学科研究。除了在夏延河项目中立即使用外，该设备组还将加强个人研究人员的其他研究活动，并加强在水质、生态系统营养动态和生物能量学、气候变化研究、生物修复和自然资源管理方面的合作可能性。装备精良的BCF是SDSM&A；T拟议的气候、土地利用、工程和教育融入社会研究中心(CIRCLE2S)发展的战略组成部分，它也符合部落科学理事会的战略目标。强大的研究设施是SDSM&amp；T与黑山州立大学、奥格拉拉·拉科塔学院和Sinte Gleska大学等地区性本科机构合作的核心。所要求的设施将大大加强教育、研究培训和新课程的开发。此次收购将加强BCF作为区域资源的作用。该奖项将：1)加强技术设施，允许大气科学研究所、土木与环境工程系、地质与地质工程系和化学系的教师开展前沿的生态和环境研究；2)为本科生和研究生提供陆地和水生生物地球化学和生态学方面的培训和教育机会；3)通过为学生提供实践和实验室培训机会的研究，进一步加强SDSM&amp；T与包括两个Tribal学院在内的地区性本科机构之间的研究和教育伙伴关系。

This award will provide a cluster of equipment to strengthen a newly established Biogeochemistry Core Facility (BCF). The equipment cluster consists of four pieces of core equipment and two supporting instrumentats. Of the four core pieces of equipment, the nutrient analyzer will be used for high throughput nutrient sampling of water samples; the in-situ multiprobe will perform real-time simultaneous analysis of nutrients, dissolved oxygen, chlorophyll and pH in aquatic ecosystems; the multi-channel O2 / CO2 respirometer will be used for mechanistic biogeochemcial studies, and the microbial assay system will be used for investigating microbial community dynamics. In addition, the two climate-controlled incubators will be used with the respirometer; and the two computers are for dedicated and integrated use with the respirometer and the multiprobe instrument. While nutrient analyzer and multiprobe help monitor and document changes in nutrient concentrations in aquatic ecosystems, the respirometer and the microbial assay system will provide insights into the biogeochemical processes that regulate nutrient concentrations in these ecosystems.These instruments will be used immediately in an interdisciplinary project that seeks to address the impacts of multiple stressors on the ecology of the Cheyenne River. The legacy of historical gold mining activities in the Black Hills, increasing population densities in the Black Hills regions, as well as the developing coal bed methane (CBM) mining activities, have adversely impacted the water quality, resource availability, and ecology of the Cheyenne River. This award will facilitate multidisciplinary studies on water quality and biogeochemistry that integrate ecosystem science and natural resource management. Beyond immediate use in the Cheyenne River project, the equipment cluster will strengthen other research activities of individual investigators and strengthen the possibilities for collaborative work on water quality, ecosystem nutrient dynamics and bioenergetics, climate change research, bioremediation, and natural resource management. A well-equipped BCF is a strategic component in the development of the proposed Center for the Integration of Research in Climate, Land use, Engineering, and Education into Society (CIRCLE2S) at SDSM&T, and it also matches the strategic objectives of the Tribal Science Council. A strong research facility is at the core of collaborations among SDSM&T, regional undergraduate institutions such as the Black Hills State University, Oglala Lakota College and Sinte Gleska University. The requested facilities will significantly enhance education, research-training and new curriculum development. This acquisition will strengthen the role of BCF as a regional resource. This award will: 1) enhance the technical facilities to allow the faculty in the Institute of Atmospheric Sciences, Departments of Civil and Environmental Engineering, Geology and Geological Engineering, and Chemistry, to perform cutting-edge ecological and environmental research, 2) provide opportunities to train and educate undergraduate and graduate students in terrestrial and aquatic biogeochemistry and ecology, and to 3) further strengthen research and education partnership between SDSM&T and regional undergraduate institutions including two Tribal Colleges, through research that provides opportunities for hands on field and laboratory training for students.
