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

该项目将支持位于教堂山的北卡罗来纳大学海洋科学研究所(IMS)为现场解散购置设备。该设施将支持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)国家科学基金会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、化学生态学和陆地边缘生态系统研究(LMER)领域拥有10笔有效的NSF研究补助金，需要现场进行DOC和DON分析。IMS还作为现场站实验室设施，为来自北卡罗来纳大学、北卡罗来纳州立大学(罗利)、东卡罗来纳大学和北卡罗来纳大学-W分校的各种呼叫调查人员提供服务。这些调查人员通常要求现场快速测定DOC/DON，以补充稳定同位素(Cand N)地球化学、营养循环、水质和营养相互作用研究。至少16个现有的国家科学基金会和10个联邦国家机构(NOAA、EPA、USGS、北卡罗来纳州水资源研究所、DOE‘I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-国家海洋和大气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。安泰克7000分析模型，外加配件将获得。仪器设计用于快速和有效地分析各种液体和气体样品，并适应上述研究需要。国际监测系统的操作、维护和技术支持的基础设施已经到位。这一设施对于成功完成北卡罗来纳州沿海和大西洋中部地区现有的和未来由国家科学基金会支持的研究项目至关重要。

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.
