In situ measurement of sediment geoacoustic properties for ONR Seabed Characterization Experiment

Abstract

Two main goals of this proposed effort are to 1) provide a geo-acoustic profile for the sediments in the frequency band of 600 Hz ~ 10 kHz and 2) better understand mud properties and their influence on sound propagation. Under this tasking, UW will deploy the Sediment Acoustic-speed Measurement System (SAMS) during the ONR sponsored Seabed Characterization Experiment scheduled for spring 2017. SAMS measurements will be made along a the main acoustic propagation track every 3 km. Analysis of data will be performed to quantify the large scale bottom characteristics, including sediment sound speed, attenuation, and bottom layering. The performer will collaborate with other participating PIs to validate geo-acoustic inversion models. Results will be published in referred journals.
