Abstract
Two new methods of acoustic monitoring of the sea medium are tested in a shelf region. One of the methods is the difference-pulse technique in which the variability of the medium is characterized by the difference in the energies of the sequences of arrivals of two multiray signals. The other method is the self-sustained oscillator technique in which the information on the changes that occur in the water temperature, the velocity of currents, and other parameters of the medium is obtained from the frequency deviation of a self-sustained oscillator that has a feedback loop closed through the underwater sound channel.
