Two conclusions are obtained by analyzing the fluctuation data of the temperature field and the sound transmission in the South China Sea from ASIAEX 2001 volume interaction experiment. First of all, the peak to peak value of the particle vertical mean displacement due to the internal waves exceeds 40 m. Secondly, the peak to peak value of the sound transmission fluctuations represented by the pulse leading edge fluctuations of the travel time average exceeds 100 ms. Based on that, the major components of the internal waves are obtained by analyzing the spectrum of the temperature field fluctuations. The spectrum structures of the temperature field fluctuations in the across shelf and the along shore directions are compared respectively, and the spectrum structures of the sound transmission in such two different directions are also compared. The multi path signals and the travel time of the pulse are respectively used to capture the information of the sound transmission fluctuations, and their spectrum structures are compared also.
