Measurements and Analysis of Acoustic Bottom Interaction in the Northwestern Mexican Basin

Abstract

An engineering test of the Acoustic Data Capsule (ACODAC) was conducted in the Western Gulf of Mexico on 27 April 1979. In addition, bottom loss data were collected. These data were reduced using ARL:UT's multipath processing system. Calculated bottom loss increased with frequency and bottom grazing angle, ranging from approximately 1 dB to 6 dB. Using available geoacoustic data and a bottom loss model, theoretical bottom losses were generated. A good match between actual and theoretical values was obtained. Thus, a relatively accurate geoacoustic model of the Western Gulf of Mexico was derived.
