• underwater vehicles

A method for observing acoustic scattering due to reflection/refraction by a fish aggregation and absorption caused by sound propagation through a fish aggregation using autonomous underwater vehicles (AUVs) is presented in this paper, and the merits and challenges of the method are discussed. Results from an experiment conducted off Cape Hatteras, NC, USA, in May 2012 are used to illustrate this experimental technique. Results from the oceanographic and acoustic data collected are presented along with discussions on directions for future research and how to further improve this technique.
