A Study of Propagation Loss Dependence on Sediment Layer Thickness Using the Fast Field Programhe intermediate layer is lossy produces an increasing loss with increasing layer thickness by straightforward absorption. This paper uses the Fast Field Program (FFP) to investigate these effects parametrically in a three layer simulation. It is shown that dependence of loss on layer thickness may t

Experimental Confirmation of Horizontal Refraction of Sound Propagation in a Wedge-Like Oceanls which showed significant bearing shifts due to repeated reflections from the ocean surface and bottom. The obliqueness of the azimuthal launch angle with respect to the shore line prevented the local grazing angle from becoming large enough to produce much bottom loss which is in accord with pred

Acoustic Propagation over Large-Scale Linear Ocean Slopes generic class (passive margin) was chosen for detailed acoustic propagation calculations. The passive-margin slope is common in the North Atlantic, has a vertical angle of 2.8°, and is covered by 500 m of silt. Using a summer Sargasso Sea sound speed profile, numerous calculations of transmission l

re of the seafloor is still far from complete. Underwater acoustics concerns itself today with the phenomena of propagation and noise at frequencies and ranges that require an understanding of acoustic interaction at both of its boundaries, the sea surface and seafloor, over depths ranging from tens to thousa978-1-4612-9293-7978-1-4613-2201-6
