High-fidelity simulations of sound propagation in the oceans

We will present a novel 3D time-dependent solver for acoustic waves suitable for low frequency sound in realistic shallow water environments. The bathymetry, properties of the seabed and the ocean are included in the numerical model. The sound sources are modeled as point sources, and can be located both in the water and in the seabed. Typical applications are low frequency sound propagation from offshore wind farms (where the sound sources are typically in the seabed) and large ships (where the sound sources are below the sea surface). Time stability is achieved by combining summation-by-parts (SBP) finite difference operators and the projection method to impose boundary conditions.
