Instrumentation and Methods of Acoustic Monitoring of Hydrophysical Processes in the Shallow Sea
To develop the system of long-term continuous monitoring of hydrophysical processes in the shallow seas and shelf zones of the World Ocean and to have a possibility of obtaining real-time data is an important problem when studying the dynamics and structure of waters in these areas. Acoustical methods of flow field and temperature monitoring allow to measure integral characteristics of these processes, whereas the usual hydrological measurements give us information only about the local characteristics. However, the peculiarities of sound propagation in the shallow sea require an adaptation of existing methods to the conditions of intense interaction between acoustic field and bottom as well as an essential improvement of the methodology and technology of remote acoustic sensing of the ocean. Discussed in the paper are the performances of acoustic sources, transceivers and receiving systems with the use of vector-phase to sound the sea medium by phase-manipulated signals within 250-2500-Hz frequency range. As examples of using them some results of studying the flow fields and temperatures in the Japan Sea shallow waters by acoustical methods are considered.
