RUI: Flux of Dissolved Organic Carbon in Coastal Rainwater

小行星9530069 该项目调查收集在沿海地区的威尔明顿，北卡罗来纳州的雨水样本的化学成分，并涉及溶解有机碳（DOC）的浓度变化的空气质量的起源。威尔明顿站点（UNCW）适合湿沉降研究，因为它接收来自大陆和海洋风暴的降水。 PI在威尔明顿现场进行的十年雨水研究表明，两种风暴类型的雨水化学成分在pH值、无机离子、甲酸和乙酸以及寒冷季节过氧化氢浓度方面存在差异。 从该项目获得的结果将有助于量化通过湿沉降从大气中去除的DOC水平。 这一信息与影响大气中碳积累的过程有关。 作为本科院校（RUI）活动的研究，为期三年的项目将支持一名全日制研究生（硕士水平）和六名本科生作为暑期研究助理。 学生助理将参与样品收集，化学分析和有关降水事件的数据解释。 UNCW雨水项目是在分析化学研究应用领域培训本科生的有效机制。 该项目将继续为科学人力资源的开发作出重大贡献。 * ATM-9530069

9530069 Willey The project investigates the chemical composition of rainwater samples collected at a coastal location in Wilmington, NC, and relates variations in the concentrations of dissolved organic carbon (DOC) to air mass origin. The Wilmington site (UNCW) is suited for wet deposition research because it receives precipitation from continental and maritime storms. The decade of rainwater research conducted by the PI at the Wilmington site shows the chemical composition of rain from the two storm types to differ with respect to pH, inorganic ions, formic and acetic acids, and during cold seasons, hydrogen peroxide concentrations. Results obtained from the project will help to quantify levels of DOC that are removed from the atmosphere through wet deposition. This information is relevant to processes affecting carbon accumulation in the atmosphere. As a Research in Undergraduate Institutions (RUI) Activity, the three-year project will support one graduate student full-time (masters level), and six undergraduate students as summer research assistants. Student assistants will be involved in sample collection, chemical analysis, and data interpretation relating to precipitation events. The UNCW rainwater project has been an effective mechanism for training undergraduates in an applied area of analytical chemical research. The project will continue to make significant contributions to the development of human resources in science. *** ATM-9530069
