Abstract : A team from APL-UW made monostatic reverberation and bistatic forward scattering measurements in a shallow water channel (depth 25.6 m) located within the Dry Tortugus collection of islands (24 deg 36.7'N 82 deg 50.7'W) during the period 9-17 February 1995. Accompanying the acoustic measurements were continuous measurements of wind speed and surface wave spectra, including wave directional information. The data will be used for sonar model development and model/data comparisons and in underwater system design, development, and performance predictions. The experiment, called the Torpedo Environmental Acoustic (TEVA) experiment, was conducted in conjunction with the Coastal Benthic Boundary Layer (CBBL) experiment organized by the Naval Research Laboratory, whose focus included measuring the geoacoustic and acoustic properties of the sea bed. The detailed environmental characterization afforded by combining assets of both the TEVA and CBBL experiments will also allow rigorous comparisons of acoustic models and measurements.
