Depth-dependent resonant target strength analysis of a dense Atlantic Herring school from wide-area OAWRS and localized 3D morphology sensing

The Journal of the Acoustical Society of America, 2008
The depth-dependent target strength of Atlantic Herring is estimated at several distinct bandwidths close to their resonance frequency for a localized, highly dense school observed during the NOPP-sponsored Gulf of Maine Experiment on September 22, 2006.

Atlantic herring low frequency target strength estimation from ocean acoustics wageguide remote sensing (OAWRS) data in the Gulf of Maine over 10 days of observation.

The Journal of the Acoustical Society of America, 2009
During the Gulf of Maine acoustic experiment in the fall of 2006, massive shoals of Atlantic herring were instantaneously imaged over wide areas using an ocean acoustics waveguide remote sensing (OAWRS) system during evening to midnight hours over a period of 10 days from Sept. 26 to Oct. 5.

Spatial and temporal coherence of scattered field from large fish groups instantaneously imaged with ocean acoustics waveguide remote sensing (OAWRS).

The Journal of the Acoustical Society of America, 2009
Wide area sonar system, such as OAWRS (ocean acoustics waveguide remote sensing), can instantaneously image large shoals of fish spanning tens of kilometers from long ranges in an ocean waveguide. An analytic and numerical model is developed for the spatial and temporal coherence of the scattered field from a large group of fish in a shallow water ...
