Impact of depression to elevation internal soliton wave conversion on upslope acoustic propagation—A simulation

Depression to elevation soliton wave conversion has been observed at the South China Sea shelf break during the recent AsiaEX experiment. Numerical simulation of the internal soliton conversion process for a two-layer fluid has been used to generate a range/time-dependent sound speed profile for upslope propagation along a 20-km propagation path. Acoustic signal properties during various stages of soliton conversion are compared. [Work supported by the ONR Ocean Acoustic Program and ONRs NRL base funding.]
