Monterey Bay Acoustic Tomography: Ray Tracing and Environmental Assessment

Abstract

This thesis recommends the locations for placement of five sonobuoys which are to be used in the 12-16 December 1988 acoustic tomography experiment in Monterey Bay. The experiment will test a low-cost tomographic system for studying internal waves and surface waves. The five sites were determined to be the most optimal locations for acoustic signal acquisition, based on predicted eigenray simulation and oceanic environment assessment. The Multiple Profile Ray-Tracing Program (MPP) simulated the probable ray paths from the specified source location to receiver positions throughout Monterey Bay, predicted eigenrays for the various sites, and determined the arrival time, transmission loss, and ray path for each eigenray.
