Verification and Refinement of the Internal Wave Alarm
Abstract
This proposal is to participate in 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 will be deployed from the 500 misobath 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 predictability of wave arrivals will be determined via the Luzon Strait Nowcast/Forecast system (LZSNFS). A novel new model application will be to assimilate real-time data from ocean gliders deployed in the central basin (near 2000m depth), then use the moorings farther west to verify the predicted waveamplitudes and arrival times. 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 a"rea around Dongsha Atoll.
