Effect of the variability of hydrological conditions on the sound field interference structure in a shelf region

Computer simulations are performed to study the effect of internal waves and heating of the surface water layer on the behavior of the local spectral maximums of the interference sound field in coastal slope conditions, as applied to the operation of the self-sustained oscillator technique for monitoring the ocean. Results of testing the self-sustained oscillator technique on a 1-km-long propagation path are presented.
