Analysis of Acoustic Influences of Environmental Parameters in Realistic Submarine Canyon Environments: Special Research Award in Ocean Acoustics, Postdoctoral Fellowship of Brendan DeCourcy

Abstract

The overall project goal is understanding acoustic propagation in and around submarine canyons, with an emphasis on how the submarine canyon features drive key propagation behavior. Specific goals include explaining how sound field properties are controlled by strongly range-dependent characteristics of the environment including steep bathymetric slopes, sound speed fronts along canyon shelf-breaks, and internal waves. An understanding of the sensitivity of acoustic measurements to variable environmental features was sought, as well as relative influence of range-variable parameters. An additional goal was to use this information to assist in corrections to acoustic measurements to account for known submarine canyon influence.
