Abstract:
The long term goals of our work on acoustic uncertainty due to fish and marine mammals are to 1 understand the nature of low-to-medium frequency 100-2000 Hz acoustic scattering specifically reverberation and attenuation by fish schools and larger marine mammals, 2 advance our acoustic methods of quantitatively imaging fish schools and tracking vocalizing marine mammals, and 3 understand the correlation between the detailed physical oceanography and the biology and acoustics. Our primary objectives this year were 1 perform our year two major experiment off Cape Hatteras, N.C. to measure the acoustics, biology, and physical oceanography of fish schools and if present marine mammals, 2 continue analysis of our year one survey cruise data, and 3 compare the year one and year two results, as this comments on the variability in the ecosystem.
