Studies of the acoustics of multiphase ocean-bottom materials

Abstract

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, and sediments in the arctic that include methane hydrate. This in turn benefits sonar operation in shallow water, buried object detection, sonar operation and acoustic communications in shallow water, and improves our understanding of the arctic environment post-climate change. The near term objective is for this PI to continue to conduct laboratory and at-sea measurements of the acoustic properties of the aforementioned multi-phase ocean-bottom materials and to investigate their impact on ocean propagation, and to conduct the planning activities required of my position as co-chief scientist for the upcoming Sediment Characterization Experiment. Actual conduct of, and participation in the field exercises will be funded through a separate proposal.
