This paper investigated the role that tidal and wind-driven flows and buoyant river plumes play in the development of the Holocene clinothem in the Gulf of Papua. Time series data from bottom tripods and a mooring were obtained at four locations near the mouth of the Fly River during portions of 2003 and 2004. Flows in the Gulf of Papua during calendar year 2003 were hindcast every 3 h using ...
This paper describes a method for estimating spatially variable bottom roughness lengths (kb) in friction-dominated coastal regions where dense measurements of the significant wave height are available. The method utilizes a numerical wave model to calculate wavefields. The model-predicted significant wave height is compared to a control simulation with a known kb field, which is a proxy for measured wave heights. The error is used in combination with an influence ...
Observations that extensive bottom scour along the outer continental shelf under Hurricane Ivan resulted in the displacement of more than 100 million cubic meters of sediment from a 35x15 km region directly under the storm's path are presented. Sediment resuspension was accomplished by the extreme waves generated by Ivan and, transported by strong near-bottom wind-driven currents. The sediment transport was primarily westward along the shelf, but also contained a significant ...
