Chinese experiments in the late 1980’s-90’s showed that the interaction of low frequency (10-1000 Hz) sound with nonlinear coastal internal waves (soliton trains) could cause a 40 dB drop in sound intensity due to scattering. These observations resulted in an interest in coastal nonlinear internal waves that continues to this day. In this talk, I will review the history and results of the acoustics/nonlinear internal wave research. I will then address the questions one must ask after a prolonged effort: Are we there yet? Is there anything useful left to do?
