Ship Entering Puget Sound

This is an animation of a simulated acoustic levels due to a ship entering Puget Sound through the Strait of Juan de Fuca.  AIS information was used for the ship’s position vs time.  Applied Ocean Sciences used a parabolic equation model to propagate the radiated sound from the ship as it moved through each location.  Notice how the characteristics of the propagated sound change as the ship moves from somewhat deep water to shallow water and into the strait. This simulation was done at a frequency of 25 Hz. AOS is a recognized leader in underwater acoustics including simulating ocean noise due to wind, shipping, biologics, pile driving, and other natural and man-made sources.
