Using industry well data and an existing, high-quality industry MCS data set acquired in the Neogene carbonate and mixed carbonate/siliciclastic sequences off northwest Australia, the researchers will undertake a comprehensive sequence stratigraphic analysis, constrain sedimentary processes, flexurally backstrip to determine paleodepths and depositional geometries, infer paleocurrents, and update IODP proposal 667. This research is one step in fulfilling the scientific need for a Southern Hemisphere analog to Leg 166 drilling along the Bahamas sea-level transect and should provide a direct comparison with results already obtained and anticipated (through possible future drilling) on the New Jersey margin. A state-of-the-art industry data set has been donated for this effort, which will provide an unprecedented understanding not only of eustatic sea level changes and erosional/depositional processes on this margin, but also of channel morphology, reefs, karst, and canyons in three dimensions. The program provides for training of graduate and undergraduate students, serves high-priority IODP goals, and complements research being conducted under the ONR STRATAFORM and NSF MARGINS programs.

利用工业井数据和现有的高质量工业MCS数据集，在澳大利亚西北部的新近纪碳酸盐和混合碳酸盐/硅质岩序列中获得，研究人员将进行全面的层序地层分析，限制沉积过程，弯曲回带以确定古深度和沉积几何形状，推断古水流，并更新IODP提案667。 这项研究是满足南半球类似于沿巴哈马海平面样带沿着钻探的第166航次的科学需求的一步，并且应该与在新泽西边缘已经获得和预期（通过未来可能的钻探）的结果进行直接比较。 一个最先进的工业数据集已捐赠给这项工作，这将提供一个前所未有的了解，不仅是海平面变化和侵蚀/沉积过程的边缘，但也通道形态，珊瑚礁，岩溶和峡谷的三维。 该计划提供研究生和本科生的培训，服务于高优先级的IODP目标，并补充了根据ONR STRATAFORM和NSF MARGINS计划进行的研究。
