项目摘要
9521254 Gilbert This project will study the composition, biological availability, and rates of uptake and release of dissolved organic nitrogen in two highly contrasting estuarine systems- the Chesapeake Bay and Georgia coastal rivers. These systems are vastly different with respect to the type, source and relative liability of dissolved organic nitrogen. Because the Principal Investigators will conduct their studies in conjunction with the two currently funded Land Margin Ecosystem Research studies at the these sites, the results will greatly enhance the understanding of these important coastal aquatic environments. The significance of the proposed research is several fold. First, in the broadcast, sense the eutrophication of nation's coastal waters and estuaries is a well recognized problem, yet we have little knowledge of the contribution and importance of organic nitrogen to this problem. Second, with the advent of new techniques, these studies will yield and appreciation of the mechanisms by which both bacteria and phytoplankton obtain their nitrogenous nitrogen will aid our ability to balance and control the flow of nitrogen through estuarine and coastal systems.
吉尔伯特9521254 该项目将研究两个高度对比的河口系统--切萨皮克湾和格鲁吉亚沿海河流--溶解有机氮的组成、生物有效性和吸收和释放速率。 这些系统在溶解有机氮的类型、来源和相对责任方面有很大的不同。 由于主要研究人员将在这些地点与目前资助的两项陆地边缘生态系统研究一起进行研究,其结果将大大提高对这些重要沿海水生环境的了解。拟议研究的意义是多重的。 首先,在广播中,感觉到国家的沿海沃茨和河口的富营养化是一个公认的问题,但我们对有机氮的贡献和重要性知之甚少。第二,随着新技术的出现,这些研究将产生和评价的机制,细菌和浮游植物获得其含氮的氮,将有助于我们的能力,以平衡和控制通过河口和沿海系统的氮流量。
