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州大学， 查佩尔山海洋科学研究所（IMS）收购 现场溶解的设备。 该设施将 支持国际监测系统国家森林基金支助项目的当前和未来需要 和附近的海洋实验室（杜克大学海洋 实验室;国家海洋渔业服务实验室）。 目前，IMS在以下领域拥有10项活跃的NSF研究赠款： 养分-生产力相互作用，氮循环，化学 生态学和陆缘生态系统研究（LMER）， 现场DOC和DON分析。 国际监测系统还作为一个外地站 实验室设施，供各种研究人员使用， 北卡罗来纳州北卡罗来纳州状态 大学（罗利），东卡罗莱纳大学和北卡罗来纳大学-西。这些 调查人员通常 需要现场快速测定DOC/DON， 碳、氮同位素地球化学，养分循环，水质 和营养相互作用研究。 至少16个当前NSF和10个 联邦/州政府机构（NOAA、EPA、USGS、UNIWA） 研究所，能源部支持的项目将受益于 DOC/DON分析设施。未来的扩展 分析需求记录在最近的范围内- 成立杜克-诺阿-海洋渔业合作研究所 海洋学（CIFO）。 Antek 7000型分析仪， 配件将被收购。 设备设计用于快速 高效分析各种液体和气体样品， 适应上述研究需要。 基础设施 的操作、维护和技术支持， 地点在IMS。 这个设施对成功地 完成现有的和未来的NSF支持的发展 研究北卡罗来纳州沿海和大西洋中部的冲断层 地区

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.
