Using Ocean Acoustics to Improve Large Shallow-Water Soliton Simulations

Abstract

Large amplitude ocean solitons can interfere with underwater acoustic signals that pass through the solitons. This can disrupt underwater acoustic communications and produce erroneous measurements in ocean acoustic experiments. Recently a simulation method has been developed that links certain properties of the soliton with properties of the affected acoustic signals. This can be used as a "feedback method" to determine if acoustic signals are likely to be affected in ocean regions where solitons may be present. Results from ocean model and acoustic model simulations are given to illustrate the method.
