Laboratory and Field Studies of the Acoustics of Multiphase Ocean Bottom Materials.

摘要

The long-term scientific objective of this project is to increase our understanding of sound propagation in ocean bottom sediments, including water-saturated sands and muds, gas-bearing sands and muds, and sediments which support seagrass. This in turn benefits buried object detection, sonar operation and acoustic communications and mine detection in shallow water. This project also includes continued analysis of data collected during Shallow Water 06 (SW06), and development of apparatus and procedures, and planning for the Sediment Characterization Experiment 2015 (referred to herein as SCE15) and its 2014 pilot survey. Finally, continued laboratory studies of the acoustics of the multiphase sediment materials mentioned above are long-term goals, coupled with the development of techniques and apparatus for in situ acoustic classification of ocean bottoms and mine hunting for Naval fleet operations.
