摘要：
The ocean medium is probed with an acoustic pulse signal having a frequency bandwidth Delta f=70 Hz and a pulse duration tau=40 s over a stationary acoustic range of 13.8 km in a shallow sea; the duration of the experiment is 1.75 h. The response function of the medium is observed to undergo only slight fluctuations, preserving its basic structure throughout the entire experiment. The fluctuations of the signal transit time do not exceed a few milliseconds.
