Abstract:

The long term scientific goal is to better understand the effects of shallow water variability on acoustic propagation at moderate frequencies. Potential sources of water column variability include random background internal waves as well as quasi-deterministic, event-like internal wave packets. The objectives of the present work are to develop models and improve simulation tools useful in achieving the long-term scientific goal. Experimental observations are used to guide the development of theoretical models. The models are implemented numerically and compared to experimental results.
