This is a project to study the processes of sediment transport and accumulation that lead to development of the clinoforms on the Gulf of Papua (GoP) continental shelf. Shelf clinoforms are the dominant components of continental-margin stratigraphy, but little is known about the processes that create them. By combining field research (seismic profiling and piston coring) and numerical modeling, quantitative understanding of mid-shelf clinoform development at geologic time scales can be developed. These studies will test the hypothesis that the predominant mechanism for creating the present-day clinoform morphology is across-shelf gravity flow of fluid muds, whereas underlying strata may have formed in different conditions in response to changing rates of sea-level rise and sediment supply.

这是一个研究导致巴布亚湾(GOP)大陆架上床状构造发育的沉积物迁移和堆积过程的项目。陆棚斜形是大陆边缘地层学的主要组成部分，但人们对其形成过程知之甚少。通过将野外研究(地震剖面法和活塞取心)与数值模拟相结合，可以在地质时间尺度上对陆架中床状发育进行定量的理解。这些研究将检验这样一种假设，即形成今天斜床形态的主要机制是流体泥浆的跨陆架重力流动，而下伏地层可能是在不同的条件下形成的，以响应海平面上升和沉积物供应的变化速度。
