The geological evolution of the Indian Ocean is the most poorly understood of all the major ocean basins. In part this has resulted form diversity of approaches and objectives of the major research cruises in the Indian Ocean. Both United States and foreign scientists have concentrated on specific tectonic or sedimentary problems, but no major cruises have concentrated on an integrated understanding of its geologic history. This has resulted in a wide distributed and non-uniform data base. A second problem has been the logistical complexity of supporting U.S. and foreign cruises in the Indian Ocean, resulting in an overall data base in any country that is insufficient to adequately address the total history of the ocean basin. The objective of the present recommended award is to compile topographic, magnetic and satellite derived gravity field from the Indian Ocean. U.S. scientists will work closely with French and Australian researchers to ensure that the data base includes results from the most recent cruises. These compilations will be used to define (1) the early opening history of the Indian Ocean; (2) the separation of Australia and Antarctica; and (3) the closing of the seaway between Indonesia and Australia. Paleodepth charts will aid in determining the sedimentary history of the basins in the Indian Ocean. The overall compilation will be important in integrating existing data with the results of drilling planned by the Ocean Drilling Program. This is a coordinated study involving scientists from U.S. and foreign institutions. Dr. John Sclater of the University of Texas has responsibility for overall coordination of the project. He will be working with Drs. Robert Fisher (Scripps Institution) and Dr. Steven Cande (Lamont-Doherty). Drs. Roland Sclich (France), Michael Coffin (Australia) and Hugh Bergh (South Africa) will provide foreign data. The principal investigators are highly qualified and funding is strongly recommended at the following levels: FY87 & 88 FY89 & 90 Texas 69,785 73,731 Scripps 59,547 77,665 Lamont 75,654 73,141

印度洋的地质演化是所有主要海洋盆地中最鲜为人知的。这在一定程度上是由于印度洋主要研究巡航的方法和目标的多样性造成的。美国和外国科学家都专注于具体的构造或沉积问题，但没有重大的邮轮集中在对其地质历史的综合了解上。这导致了一个广泛分布和不统一的数据库。第二个问题是支持美国和外国在印度洋巡航的后勤复杂性，导致任何国家的总体数据库都不足以充分说明洋盆的全部历史。本建议奖项的目的是汇编印度洋的地形、磁场和卫星得出的重力场。美国科学家将与法国和澳大利亚的研究人员密切合作，确保数据库包括最近一次巡航的结果。这些汇编将被用来确定(1)印度洋的早期开放历史；(2)澳大利亚和南极洲的分离；(3)印度尼西亚和澳大利亚之间的海道关闭。古深度图将有助于确定印度洋盆地的沉积历史。总体汇编对于将现有数据与海洋钻探方案计划的钻探结果相结合将是重要的。这是一项由来自美国和外国机构的科学家参与的协调研究。德克萨斯大学的John Sclater博士负责该项目的整体协调。他将与罗伯特·费舍尔博士(斯克里普斯研究所)和史蒂文·坎德博士(拉蒙特-多尔蒂)合作。罗兰·斯克里奇博士(法国)、迈克尔·科芬博士(澳大利亚)和休·伯格博士(南非)将提供外国数据。主要调查人员非常合格，强烈建议在以下级别提供资金：87财年和88财年89财年。90德克萨斯州69,785 73,731斯克里普斯59,547 77,665拉蒙特75,654 73,141
