Laboratory Studies of the Impact of Fish School Density and Individual Distribution on Acoustic Propagation and Scattering
Abstract
The long-term scientific objective of this project is to increase our understanding of acoustic propagation and scattering in the presence of schools of fish, the effects of which can potentially overshadow all other acoustic mechanisms in shallow water. This in turn benefits sonar operation and acoustic communication in shallow water, and will increase the accuracy of acoustically-based fisheries surveys. This study will utilize both one- and three-dimensional acoustic resonator techniques, previously developed by the author under ONR [1, 2] and industry [3] sponsorship, and free-field measurement techniques to study the low-frequency (50 10000 Hz) acoustics of collections of model fish, large ( 10 cm diameter) encapsulated bubbles and schools of real fish in the laboratory.
