A Numerical Simulator of Ocean Internal Waves for Long-Range Acoustics

Abstract

In combination with an appropriate background ocean model, simulations of internal waves are necessary to create realistic scenarios for use in acoustic propagation studies. Our approach employs contemporary understanding of internal wave statistics with a simulator that produces two-dimensional (range/depth) slices of internal wave displacements. The method produces statistical realizations for acoustic studies that are true to ocean measurements with nominal computational cost.
