Akulichev, Victor Anatolievich,Bezotvetnykh, Vladimir Victorovich,Morgunov, Yury Nikolaevich,Polovinka, Yury Alexandrovich,Strobykin, Dmitry Sergeevich Korea Institute of Ocean ScienceTechnology 2009 Ocean and Polar Research Vol.31 No.1
When evaluating acoustic methods for measuring physical parameters in the ocean, economical and technical considerations are paramount. As an indirect method of estimating ocean dynamics, acoustic tomography has advantages over more conventional approaches. It allows the reconstruction of temperature and flow fields from the acoustic impulse time-of-flight measured along the rays propagating from the source to the receiver. However, many problems require complicated and expensive systems. To use the acoustic tomography method to best effect, developing hardware systems with sources and receivers mounted permanently on the sea bottom is crucial. Akulichev et al. presented some experimental results from shallow zones of the World Ocean that served as a motive for developing a multifunction system with acoustic hardware and software. Here we present technical features and the sea test results of the system.

Remote Acoustic Sensing Methods for Studies in Oceanology
Akulichev, Victor A.,Bezotvetnykh, Vladimir V.,Burenin, Alexander V.,Voytenko, Evgeny A.,Kamenev, Sergey I.,Morgunov, Yury N.,Polovinka, Yury A.,Strobykin, Dmitry S. The Korean Society of Oceanography 2006 Ocean science journal Vol.41 No.2
In this paper, the lines of investigation on a problem of the development of remote acoustic sensing methods in oceanology are formulated. This paper summarizes the results of investigations into the possibilities for monitoring temperature and flow fields in shallow seas. In the discussed experiments, the instrumentation being constituents of the complex for long-duration remote monitoring of marine medium climatic variability and that of the acoustic tomography of shallow sea dynamic processes is used. The acoustic instruments were located on the POI FEB RAS acousto-hydrophysical polygon (Pacific Oceanological Institute, Far Eastern Branch of the Russian Academy of Sciences) near the Gamov Peninsula. Acoustic receiving and transmitting systems operating with multiplex phase-manipulated signals (of M-codes) at frequency range 250-2500 Hz form the basis for this complex.
