Methodology for the Practical Implementation of Monitoring Temperature Conditions over Vast Sea Areas Using Acoustic Thermometry

The methodological and technical possibilities of monitoring temperature fields in the Sea Japan by acoustic thermometry methods are presented. proposed tomographic method for dynamics structure water is based on transmission reception complex phase-shift keyed signals a diagnosed track with determination travel time along various ray trajectories, followed sound speed (temperature) determination. physical prerequisites practical implementation thermometric studies at large distances “mudslide” effect—the phenomenon energy “injection“ from near-bottom shelf area to underwater channel deep ocean. Based example, an system schemes mobile stationary hydroacoustic sources promising work field oceanic climatology proposed. For numerical calculations signal propagation channels’ impulse responses between receivers, specialized database oceanological information was formed northwestern part Japan. includes all available data organizations Russia, Japan, North Korea, Republic United States (23,247 stations completed 1925 2017). In example high-precision developed transmitting receiving systems experimentally tested.
