Abstract:

The long-term goal is to develop an understanding of physical parameters of aggregations of fish that control clutter and produce improved scattering models that incorporate those parameters. This project was part of the Office of Naval Research ONR Basic Research Challenge formally entitled Acoustic Uncertainty due to Marine Mammals and Fish, which was informally known as the Fish BRC. The project was conducted in conjunction with the Naval Research Laboratory NRL Fish BRC project entitled Moment- Based Physical Models of Broadband Clutter due to Aggregations of Fish, Dr. Roger C. Gauss, Principal Investigator. The focal point of the NRL project was an at- sea experiment designed to collect and analyze clutter caused by aggregations of fish, as part of the ONR effort to mitigate the effects of clutter caused by schooling fish. The primary objective of the BayouAcoustics BA project was to assist NRL with the planning and execution of the experiment and to assist with the interpretation of data collected during the experiment. The BA effort was concerned with determining the characteristics of fishes with the potential to cause clutter during the experiment, evaluating those characteristics, and then providing the evaluations to NRL.
