9530118 Matano Remote observations indicate that the most energetic regions of the world's oceans are the offshore extensions of the Kuroshio Current, the Gulf Stream, the Agulhas retroflection, and the Brazil/Malvinas Confluence. Of all these regions, the Brazil/Malvinas Confluence is, by far, the least studied. The Brazil/Malvinas Confluence is characterized by one of the strongest oceanic temperature gradients and large seasonal latitudinal displacements (up to 5=B0) along the continental slopes of Brazil, Uruguay, and Argentina. Since the Brazil/Malvinas Confluence influences the fisheries and agricultural development of one of the most economically important areas of Latin America, it is of regional interest to understand the physical and biochemical processes with which it is associated. From a more general point of view, the Brazil/Malvinas Confluence is important for a strong water mass ventilation that affects the global thermohaline circulation and therefore is important in global climate change. Previous studies on the circulation in this region have only emphasized isolated aspects of the oceanic and atmospheric circulations without any attempt to study them as a coupled system. Scientists from Argentina, Brazil, Mexico, Uruguay, and the United States will meet to elaborate a research project to investigate coupled models of the Brazil/Malvinas Confluence, resulting in a Phase II Start-Up Grant proposal to the IAI. This proposal brings together participants from member countries of the Inter-American Institute for Global Change Research (IAI), a U.S. initiative to stimulate cooperative research on global change issues among the scientific institutions of the Americas. The NSF is the lead U.S. Government agency designated to carry out U.S. responsibilities within the IAI. %%% This workshop will bring together scientists from Argentina, Brazil, Mexico, Uruguay, and the United States to elaborate a research project to investigate the Brazil/Malvinas Confluence, an ocean current that runs along the continental slopes of Brazil, Uruguay, and Argentina. This current one of the most energetic in the world, and strongly influences the fisheries and agricultural development of one of the most economically important areas of Latin America. The Brazil/Malvinas Confluence has a strong influence on the turnover of the world's ocean water and therefore on global climate change. The Brazil/Malvinas Confluence is also one of the least studied currents in the world, in an area of the Atlantic that remains poorly understood by the oceanographic community. The four countries involved in the project bring together some of the most important research groups and computer modeling facilities in the Americas to tackle this problem, and will propose a research project to the Inter-American Institute for Global Change Research (IAI), a U.S. initiative to stimulate cooperative research on global change issues among the scientific institutions of the Americas. The National Science Foundation is the lead U.S. Government agency designated to carry out U.S. responsibilities within the IAI. *** --========================_15507136==_--

9530118 Matano Remote的观测表明，世界海洋中最活跃的区域是黑潮海流、墨西哥湾流、Agulhas回流和巴西/马尔维纳斯汇流的近海延伸。 在所有这些区域中，对巴西/马尔维纳斯汇合区的研究最少。 巴西/马尔维纳斯汇流的特点是海洋温度梯度最强，季节性纬度大， 沿着巴西、乌拉圭和阿根廷大陆斜坡的位移（5= B 0）。 由于巴西/马尔维纳斯汇流影响到拉丁美洲经济最重要地区之一的渔业和农业发展，了解与之相关的物理和生物化学过程符合该区域的利益。 从更广泛的角度来看，巴西/马尔维纳斯汇流对于影响全球温盐环流的强大水团通风非常重要，因此对全球气候变化也很重要。 以往对该区域环流的研究只强调海洋和大气环流的孤立方面，而没有试图将它们作为一个耦合系统来研究。 来自阿根廷、巴西、墨西哥、乌拉圭和美国的科学家将举行会议，详细制定一个研究项目，调查巴西/马尔维纳斯群岛汇流的耦合模型，从而向国际空间研究所提出第二阶段启动赠款建议。 这项建议汇集了美洲研究所成员国的与会者， 全球变化研究（IAI），这是美国的一项倡议，旨在促进美洲科学机构之间对全球变化问题的合作研究。 NSF是指定在IAI内履行美国职责的美国政府牵头机构。 %本次研讨会将汇集来自阿根廷、巴西、墨西哥、乌拉圭和美国的科学家，详细阐述一个研究项目，以调查巴西/马尔维纳斯群岛汇流，这是一个沿着巴西、乌拉圭和阿根廷大陆斜坡沿着的洋流。 这是目前世界上最具活力的地区之一，对渔业和农业的发展产生了强烈的影响，也是世界上最具经济效益的地区之一。 拉丁美洲的重要地区。 巴西/马尔维纳斯汇流对世界海洋水的周转，从而对全球气候变化产生重大影响。 巴西/马尔维纳斯汇流也是世界上研究最少的洋流之一，因为海洋学界对大西洋这一地区仍然知之甚少。 参与该项目的四个国家汇集了美洲一些最重要的研究小组和计算机建模设施，以解决 该研究所是美国的一项倡议，旨在促进美洲科学机构之间就全球变化问题开展合作研究。 美国国家科学基金会是美国政府指定在IAI内履行美国职责的主要机构。 *** --=
