Abstract:

LONG TERM GOALS. The long term goal of this project is to develop efficient and robust normal-mode modeling tools for research and analysis in underwater acoustics and to apply the tools to the problem of geoacoustic inversion. The modeling tools developed will continue to be distributed to other researchers in the field. OBJECTIVES. The primary objectives for this fiscal year were to make improvements to the ORCA normal mode model and to apply the model to the geoacoustic inversion benchmark problems. ORCA s capabilities were enhanced to allow the modeling of Gaussian beam sources and to include the effects of the branch line integrals. In addition, we worked to make ORCA s mode-finding and broadband algorithms more robust and efficient, and we responded to problems that users at other research facilities encountered.
