The measurement and correlation of sound velocity and temperature fluctuations near the sea surface
measurementcorre00duch.pdf (5.428Mb)Abstract
The temporal variation of salinity, temperature, water turbulence components, surface wave height, acoustic amplitude and acoustic velocity were studied statistically by computing the auto-correlations and power spectral densities. Correlation times were high for temperature fluctuations with a decay time ((-1)) being of the order of forty seconds or greater for temperature and of the order of two seconds for the other parameters. All parameters were shown to exhibit maximum energy at the periods of the predominant surface wave energy.
