Analysis of Data Obtained During the 2019 Dongsha Atoll Internal Wave Alarm Field Experiment
Abstract
This proposal is to analyze data from a field program in the vicinity of Dongsha Atoll, northeastern South China Sea, during May-July 2019. Traditional moorings and a distributed temperature sensing (DTS) cable were deployed from the 500m isobath to the top of the reef to observe the density and current fluctuations induced on the reef by large amplitude, nonlinear internal waves impinging on the reef from the east. The wave arrival times were predicted by the Luzon Strait Nowcast/Forecast system (LZSNFS). The energy/energy flux onto the reef as a function of incident wave amplitude will now be determined using the combined data sets. Island/reef effects such as reflection and refraction will also be examined. The model-predicted wave characteristics will be improved via quantitative comparisons with the observations and adjustments to the computation scheme. In collaboration with ONR 322OA, the impact of the shoaling and breaking waves on Naval operations and acoustic propagation will also be assessed. The results will provide improved knowledge and predictability of the battle space environment in the northeastern South China Sea including the area around Dongsha Atoll.
