Abstract
In order to develop ocean acoustic tomography techniques, it is very important to determine optimal receiving points and the propagation characteristics of sound in the SOFAR (SOund Fixing and Ranging) channel. We describe a preliminary computer simulation to estimate the sound arriving through a SOFAR channel across a geostrophic current. It is assumed that an ocean current is a geostrophic current and crosses the 1200 km propagation path at its center. Propagation times and detected pulsed sound waveforms are obtained in both directions of north-south propagation when the maximum flow speed changes from 0 to 153 cm/s. It is shown that a geostrophic current affects the propagation characteristics of sound. The difference in the propagation times for both directions can be used to estimate the flow speed along the propagation path.
