This award supports the participation of Prof. Henri E. Gaudette and colleagues of the University of New Hampshire in a program of cooperative research with Prof. Jader Onofre de Morais and others of the Laboratory of Marine Sciences of the Federal University of Ceara. They are collaborating in an analysis of nutrient and metal dynamics in the estuarine systems near the city of Fortaleza, Brazil. While the data will be of immediate benefit in the management of the biogeochemistry of this rapidly growing area of Brazil, the results of this project will also contribute to a broader understanding of the chemical dynamics of tropical estuarine systems in general. The river estuaries to be studied--those of the Coco, Ceara, and Pacoti rivers in the state of Ceara--are the major sources of land-based influence, both natural and human-produced, on the near-shore environment in the most heavily populated part of the State. The investigations to be conducted will determine the levels of anthropogenic impact on the three estuarine systems and the near shore environment, and will provide a data base useful for understanding and regulating possible long-term biological effects. The investigators have already been working together on some of these problems, with support from NSF, and this project is an extension of that effort. Overall, the project will utilize the analytical expertise of the U.S. investigators with the experimental experience of their Brazilian counterparts, and will help to delineate the role of estuaries in the coastal ecology of this and similar regions, and add to our knowledge of the biogeochemical dynamics of tropical estuaries.

该奖项支持新罕布什尔大学的 Henri E. Gaudette 教授及其同事与塞阿拉联邦大学海洋科学实验室的 Jader Onofre de Morais 教授及其他人员参与一项合作研究项目。 他们正在合作分析巴西福塔莱萨市附近河口系统的营养物和金属动态。 虽然这些数据将为巴西这一快速增长地区的生物地球化学管理带来立竿见影的好处，但该项目的结果也将有助于更广泛地了解热带河口系统的化学动态。 要研究的河口——塞阿拉州的科科河、塞阿拉河和帕科蒂河——是对该州人口最稠密地区近岸环境产生自然和人为陆地影响的主要来源。 即将进行的调查将确定人为对三个河口系统和近岸环境的影响程度，并将提供有助于理解和调节可能的长期生物影响的数据库。 在美国国家科学基金会的支持下，研究人员已经就其中一些问题进行了合作，该项目是这一努力的延伸。 总体而言，该项目将利用美国研究人员的分析专业知识和巴西同行的实验经验，将有助于描述河口在该地区和类似地区沿海生态中的作用，并增加我们对热带河口生物地球化学动力学的了解。
