Ocean Acoustics Turbulence Study

Abstract

The long-term goals are to: 1. Measure the three-dimensional wave number spectrum of ocean turbulence using high frequency broadband acoustic scatter. 2. Quantify the acoustic scatter that results from medium variability while other sources of scattering commonly found in the ocean are present. The acoustic scatter from a region of medium variability can arise from scalar and vector sources. The scalar component can be the result of more than one fundamental property of the medium, i.e., sound speed or density. The objective of this work is to separate and quantify the scalar sources using high frequency broadband multi-static acoustic scatter; through which the temperature and salinity spectral variances can be determined.
