Processes Controlling Depositional Signals of Environmental Change in the Fly River Sediment Dispersal System: Mechanisms and Rates of Shelf Clinoform Development

该项目将调查导致弗莱河外巴布亚湾陆架斜坡形成的沉积物输运和积累过程。这项研究将包括从河口附近到斜坡底部的各种取样和监测站，这些取样和监测站将提供关于当今沉积物运输和积累的空间和时间变化的时间序列观测。 这项研究将专门调查流体泥浆的作用，作为跨大陆架运输的沉积物，导致斜坡形态的主要机制。 包括放射性同位素测量在内的核心研究将提供季节至千年时间尺度上的沉积物迁移和积累信息。

This project will investigate the processes of sediment transport and accumulation that lead to development of the shelf clinoform in the Gulf of Papua off the Fly River. The study will include a variety of sampling and monitoring stations from near the river mouth to the base of the clinoform that will provide time-series observations on the spatial and temporal variation in present day sediment transport and accumulation. The study will specifically investigate the role of fluid muds as primary mechanism for across-shelf transport of sediment that leads to clinoform morphology. Core studies including radioisotope measurements will provide information of sediment transport and accumulation on seasonal to millennial time scales.
