Seabed Acoustic Characterization
Abstract
The long-term goals of the research are (1) to quantify the frequency dispersion of the complex sound speed in marine sediments from low to mid frequencies, and (2) to understand the coupling of physical mechanisms in the water column and the seabed in complex range and azimuth dependent littoral waveguides. The main objective of the current research is to determine the frequency dependence of the sediment sound speed and attenuation in the 10-3000 Hz band in a littoral region that has extensive geophysical and real time supporting physical oceanography measurements. A secondary objective is to develop advanced signal processing methods that can be applied to the inverse problem of estimating waveguide properties from acoustic measurements.
