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 远程观测表明，世界海洋中最活跃的区域是黑潮洋流、墨西哥湾流、厄加勒斯逆流和巴西/马尔维纳斯交汇处的近海延伸区域。 在所有这些地区中，迄今为止，对巴西/马尔维纳斯交汇处的研究最少。 巴西/马尔维纳斯交汇处的特点是海洋温度梯度最强的地区之一，以及沿着巴西、乌拉圭和阿根廷大陆坡的较大季节性纬度位移（高达 5=B0）。 由于巴西/马尔维纳斯交汇处影响着拉丁美洲经济最重要地区之一的渔业和农业发展，因此了解与其相关的物理和生化过程具有区域意义。 从更普遍的角度来看，巴西/马尔维纳斯交汇处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。 先前对该地区环流的研究仅强调海洋和大气环流的孤立方面，而没有尝试将它们作为一个耦合系统进行研究。 来自阿根廷、巴西、墨西哥、乌拉圭和美国的科学家将齐聚一堂，详细阐述一个研究项目，以调查巴西/马尔维纳斯汇合处的耦合模型，从而向 IAI 提出第二阶段启动拨款提案。 该提案汇集了美洲全球变化研究所（IAI）成员国的参与者，该研究所是美国的一项倡议，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 内履行美国职责的主要美国政府机构。 %%% 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，共同制定一个研究项目，以调查巴西/马尔维纳斯交汇处，这是一种沿着巴西、乌拉圭和阿根廷大陆坡流动的洋流。 这是目前世界上最具活力的地区之一，对拉丁美洲经济最重要地区之一的渔业和农业发展产生了强烈影响。 巴西/马尔维纳斯交汇处对世界海水的周转以及全球气候变化具有重大影响。 巴西/马尔维纳斯汇合处也是世界上研究最少的洋流之一，该洋流位于大西洋的一个区域，但海洋学界对这一区域仍知之甚少。 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来解决这一问题，并将向美洲全球变化研究所（IAI）提出一个研究项目，该研究所是美国的一项倡议，旨在促进美洲科学机构之间关于全球变化问题的合作研究。 美国国家科学基金会是指定在 IAI 内履行美国职责的主要美国政府机构。 *** --========================_15507136==_--
