This research involves a study of seismic sequences in basins in the Northwestern Australian Margin and in the East Coast of the United States, areas which have contrasting rifting histories. The study will evaluate Vail's Sea Level fluctuation curve which is the present standard and has been used by many earlier investigators for evaluation and comparison of global seismic sequences. This study will apply this curve to a unique data set of two contrasting areas to which this curve has not previously been applied. Vail's curve was defined on the basis of an Exxon Corporation stratigraphic data base, most of which is proprietary in nature and not available to other scientists for scrutiny. The proposed independent verification of the Vail curve is long overdue and will have a substantial impact on future research concerning the seismic stratigraphy of continental margins and the use of models to understand development of seismic sequences.

这项研究涉及澳大利亚西北部边缘和美国东海岸盆地的地震序列研究，这两个地区具有对比鲜明的裂谷历史。这项研究将评估维尔的海平面波动曲线，这是目前的标准，并已被许多早期的研究人员用于评估和比较全球地震序列。这项研究将把这条曲线应用于两个对比区域的独特数据集，这条曲线以前没有应用过。维尔的曲线是根据埃克森公司的地层数据库定义的，其中大部分是专有的，不提供给其他科学家进行审查。拟议的维尔曲线独立核查工作早就应该进行，这将对今后有关大陆边地震地层学的研究和利用模型了解地震层序发展情况产生重大影响。
