Since electromagnetic propagation in seawater is very limited, acoustics provide the primary means of remote sensing and communication under the ocean. However, the ocean is a complex environment with large variations both temporally and spatially. Historically, acoustic propagation and scattering for underwater acoustics have been modeled using approximations to the Helmholtz equation. However, with the increase of computing power, finite element models are now accessible for the large-scale problems in ocean acoustics. These models are particularly powerful in these applications because they can capture the complexity of the environment. This talk will provide an overview of the application of finite element modeling for ocean acoustics applications in the underwater environment as well as a glimpse into the future of the discipline.
