Seabed Characterization for SW2013 Mid-Frequency Reverberation Experiment
Abstract
Seabed geoacoustic structure exhibits variability on a wide spectrum of spatial scales. An experiment was designed and conducted (under the TREX13 experiment) to measure those scales in an inner shelf ridge and swale environment off the coast of Panama City, Florida. One of the surprising results was the observation that significant scales of lateral variability in the sub-bottom exist at scales of 1-10 m. This was observed at both measurement sites, one on a small ridge and one in a swale. Very large differences were observed between the gross sediment properties on the ridge and in the swale despite there being only 30 cm difference in water depth between them. Some of the physical properties could be estimated, but many of the geoacoustic results are rather qualitative. New techniques are required for fully quantifying the geoacoustic variability in such a heterogeneous environment.
