An Experiment in High-Frequency Sediment Acoustics: SAX99

Abstract

A major high-frequency sediment acoustics experiment was conducted near the northwestern coast of Florida, USA. The experiment addressed high frequency acoustic backscattering from the seafloor sediment, acoustic penetration into the sediment, and acoustic propagation within the sediment. Extensive in situ measurements were made of the sediment geophysical properties, and biological processes affecting the environment were studied. An overview is given of the entire measurement program. Initial results from APL-UW measurements and modelling are then described.
