9314029 Davies This award will support the U.S. contribution to a cooperative project with British scientists which will integrate and synthesize data from Ocean Drilling Project and Deep Sea Drilling Project sites in the circum Antarctic basins, the south Atlantic and the southern Pacific and Indian Oceans. The basic objective of the project is to determine the history of bottom water formation around Antarctica and to trace the development of the Circum Polar Current in response to the breakup of Gondwana. This will be accomplished through the preparation and interpretation of maps showing changes in sediment distribution in the southern oceans through the Cenozoic. These data will be integrated with stable isotope and other time-series and faunal data from drilling sites. In addition to further defining Cenozoic paleoceanography, the data and interpretations from this project will be important in defining future ocean drilling objectives in the region. ***

9314029戴维斯该奖项将支持美国对与英国科学家合作项目的贡献，该项目将整合和综合南极环流盆地、南大西洋、南太平洋和印度洋的大洋钻探项目和深海钻探项目现场的数据。该项目的基本目标是确定南极洲周围底水形成的历史，并追踪极地环流的发展，以响应冈瓦那冰川的解体。这将通过编制和解释显示新生代期间南大洋沉积物分布变化的地图来实现。这些数据将与稳定同位素和来自钻探现场的其他时间序列和动物群数据相结合。除了进一步确定新生代古海洋学外，该项目的数据和解释对于确定该区域未来的海洋钻探目标将是重要的。***
