Establishing a Dissolved Organic and Nitrogen Analytical Facility at the UNC-CH Institute of Marine Sciences

该项目将支持北卡罗来纳大学教堂山分校海洋科学研究所（IMS）购买现场溶解设备。该设施将支持美国国家科学基金会在IMS和附近海洋实验室（杜克大学海洋实验室；国家海洋渔业服务实验室）支持的项目的当前和未来需求。目前，IMS在营养生产力相互作用、氮循环、化学生态学和土地边缘生态系统研究（LMER）领域获得了10项活跃的NSF研究资助，需要进行现场DOC和DON分析。IMS还为来自北卡罗来纳大学- ch、北卡罗来纳州立大学（罗利）、东卡罗莱纳大学和北卡罗来纳大学- w的各种合作研究人员提供现场站实验室设施。这些研究人员通常需要快速的现场DOC/DON测定，以补充稳定同位素（c和N）地球化学，养分循环，水质和营养相互作用研究。目前至少有16个NSF和10个联邦和州机构（NOAA， EPA， USGS， UNC水资源研究所，DOE）支持的项目将受益于DOC/DON分析设施。在最近成立的杜克大学-北卡罗来纳大学-美国国家海洋和大气管理局渔业海洋学合作研究所（CIFO）的范围内记录了这些分析需求的未来扩展。一个Antek模型7000分析，加上配件将获得。设备设计用于快速有效地分析各种液体和气体样品，并适应上述研究需求。IMS已经具备了操作、维护和技术支持的基础设施。这个设施是至关重要的成功完成现有的和未来的NSF支持的研究推力在沿海北卡罗莱纳州和大西洋中部地区的发展。

This project will support the University of North Carolina at Chapel Hill's Instituteof Marine Sciences (IMS) acquisition of equipment for an onsite dissolved. This facility will support current and future needs of NSF-supported projects at IMS and nearby marine laboratories (Duke University Marine Laboratory; National Marine Fisheries Service Laboratory). Currently, IMS has 10 active NSF research grants in the areas of nutrient-productivity interactions, nitrogen cycling, chemical ecology and land margin ecosystems research (LMER) requiring on site DOC and DON analyses. IMS also serves as a field station laboratory facility for various callaborating investigators from UNC-CH, N.C. State University (Raleigh), East Carolina University and UNC-W. These investigators routinely require rapid on site DOC/DON determinations to compliment stable isotope (Cand N) geochemistry, nutrient cycling, water quality and trophic interaction studies. At least 16 current NSF and 10 federaVstate agency (NOAA, EPA, USGS, UNC Water Resources Research Institute, DOE'I-supported projects will benefit from a DOC/DON analytical facility. Future expansion of these analytical needs is documented within the scope of the recently- established Duke-UNC-NOAA Cooperative Institute of Fisheries Oceanography (CIFO). An Antek model 7000 analyses, plus accessories will be acquired. Equipment is designed for rapid and efficient analyses of a variety of liquid and gas samples and adaptable to abovementioned research needs. The infrastructure for operation, maintenance and technical support is already in place at IMS. This facility is of vital importance to successful completion of existing and development of future NSF- supported research thrusts in coastal North Carolina and the mid-Atlantic region.
