Compilation of Topographic, Magnetic and Geophysical Data from the Indian Ocean

印度洋的地质演化是所有主要海洋盆地中最不为人所知的。这在一定程度上是由于印度洋各主要研究巡航的方法和目标各不相同。美国和外国科学家都把注意力集中在具体的构造或沉积问题上，但没有一个大型游轮集中在对其地质历史的综合了解上。这导致了广泛分布和不统一的数据库。第二个问题是在印度洋支持美国和外国游轮的后勤复杂性，导致任何国家的整体数据库都不足以充分解决海洋盆地的全部历史。目前建议的奖项的目的是汇编印度洋的地形、磁场和卫星引力场。美国科学家将与法国和澳大利亚的研究人员密切合作，以确保数据库包括最近一次巡航的结果。这些汇编将用于定义(1)印度洋早期开放的历史；(2)澳大利亚与南极洲的分离；(3)关闭印度尼西亚和澳大利亚之间的海道。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井计划计划的钻井结果相结合非常重要。这是一项涉及美国和外国机构科学家的协调研究。德克萨斯大学的约翰·斯克拉特博士负责该项目的整体协调工作。他将和dr。罗伯特·费希尔（斯克里普斯研究所）和史蒂文·坎德博士（拉蒙特-多尔蒂研究所）。Drs。Roland Sclich（法国），Michael Coffin（澳大利亚）和Hugh Bergh（南非）将提供国外数据。主要研究人员是高素质的，强烈建议在以下级别提供资金：FY87 &amp； 88 FY89 & 90 Texas 69,785 73,731 Scripps 59,547 77,665 Lamont 75,654 73,141

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.
