Selected Papers on Ocean-Seismo Acoustics Low-Frequency Underwater Acoustics Based on the SACLANTCEN Contributions to a Symposium Held by SACLANTCEN on 10-14 June 1985

Abstract

CONTENTS: Time dependence of infrasonic ambient seafloor noise on a continental shelf; The use of Love waves to determine the geoacoustic properties of marine sediments; Medium induced low frequency fluctuations in acoustic transmission loss; Directional measurements of low frequency acoustic backscattering from the seafloor; Shear properties of ocean sediments determined from numerical modelling of Scholte wave data; Evaluation of low frequency bottom backscattering strength vs grazing angle by means of multiple beamforming; Spatial variability of surficial shallow water sediment geoacoustic properties; Evaluation of experimental techniques for determining the plane wave reflection coefficient at the sea floor; Interface wave studies on the Ligurian shelf using an OBS array: experimental results and propagation models; and Low frequency anomalies in the reflection behaviour of marine sediments.
