Regional Dependence of Very Low-Frequency Sound Attenuation in the Deep Sound Channel: Correlation with Internal Wave Measurements. A Paper Presented at the Joint Meeting of the Acoustical Society of America and the Acoustical Soc

摘要

The most promising mechanism for the very low-frequency sound attenuation observed in the deep sound channel is diffusive scattering by internal waves, Mellen et al. (1976) have obtained estimates for the extra attenuation using the Garrett-Munk internal wave model and found consistency with the lower experimental values reported. Kibblewhite et al. (1978) have shown a definite regional dependence in the Pacific. This paper compares regional oceanographic measurements with the Garrett-Munk internal wave model and also correlate local acoustic measurements with estimates of the extra attenuation.
