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.

This research is one step in满足对沿巴哈马海平面样带的南半球类似物的科学需求，并应与已经获得和预期的结果（通过可能的将来的钻孔）进行直接比较。 为这项工作捐赠了一个最先进的行业数据集，这将不仅可以在此保证金上提供对欣赏海平面变化以及侵蚀/沉积过程的前所未有的理解，还可以在三个维度上对渠道形态，礁石，karst和峡谷提供三个维度的渠道形态。 该计划规定了培训研究生和本科生，为高优先级的IODP目标服务，并根据ONR StrataForm和NSF Margins计划进行了补充。
