Development and Application of a Three-Dimensional Seismo-Acoustic Coupled-Mode Model
Abstract
The overall goal of this research is the development of an accurate and reliable propagation model applicable to environments with elastic seabeds which exhibit strong range dependence in all three spatial dimensions. The objective of work in this report is to gain an understanding of the physics of propagation in continental shelf areas, specifically horizontal refraction and mode coupling induced by 3D inhomogeneities in the waveguide. The main accomplishments of 2015 include: (1) 3D propagation modeling out-of-plane arrivals from a scale model experiment, (2) development of a robust mode finding algorithm for environments with elastic bottoms, (3) and propagation modeling of interface waves with comparison to measured data. A robust normal-mode code for calculating the eigenvalues and eigenfunctions in environments with elastic bottoms is a necessary step towards the development of a 3D seismo-acoustic coupled-mode model.
