Spatial Structure of Deep Water Acoustic Propagation
Abstract
The long-term goals of this research are to understand the spatial (and less so the temporal) structure of deep-water acoustic propagation, with particular emphasis on deep-water ambient noise. Background noise in the open ocean is driven by local wind generated surface noise; interference from nearby ships; and at low frequencies is dominated by energy received from ships at significant distances. The extent to which scattering from seamounts, downslope conversion and internal waves affects the spatial structure (mode composition) of this ambient noise is the primary focus of this work. In spite of the deep water focus of this research, it turns out that sediment properties (geo-acoustics) of downslope regions and seamounts plays a role in the amount and type of scattering from these bathymetric features.
