Abstract: | Acoustic fluctuation data of characteristic time scales from 1 hour to 2 hours at a frequency of 406 Hz are extrapolated to frequencies under 100 Hz. These results indicate that fluctuations on this scale may have little consequence in applications involving relative phase stability between widely separated hydrophones. Fluctuation model results are reported. The model uses a source moving in a vertically stratified ocean of relatively simple structure to generate fluctuations similar to experimental data. |
