Analysis of Acoustic Influences of Environmental Parameters in Realistic Submarine Canyon Environments: Special Research Award in Ocean Acoustics, Postdoctoral Fellowship for Brendan DeCourcy
Abstract
In this proposal, theoretical analyses will be the primary tool, with numerical methods and experimental data to supplement the appr""oach. Realistic mathematical models of a submarine canyon environment will be developed, and analytical techniques will be used to p""ursue convenient equations to describe parameter dependence and sensitivity. To arrive at such equations, conserved quantities in th"e 3-D environmental models will be identified and analyzed to extract implicit parameter dependence information. This will lead to f"ormulas for parameter sensitivity of acoustic quantities such as group speeds, modal attenuation coefficients, and interference wave""lengths. Mode coupling will be examined for its influence on conservation formulas, as well as its sensitivity to parameter variatio""ns. Numerical models based on experimental data from the Hudson Canyon on the New Jersey Shelf, the Mien-Hua Canyon in the East Chin""a Sea, as well and the Shallow Water ~06 (SW06) experiment will be developed, providing a numerical environment to test the analytic"al calculations for parameter sensitivities.
