For the measurement of near-surface sediment geo-acoustic characteristics in water depths up to 200 cm, the Acoustic Measurement System has been developed and tested. At a sediment depth of 30 cm, shear wave velocity is recorded at pathlengths of 33 and 71 cm. At sediment depths of 10, 20, and 30, compressional wave velocity and attenuation are recorded at pathlengths of 58 and 100 cm. To support the existing measurement arrangement, preliminary tests that led to the current design are described. The system’s properties are discussed, and a plan for expanding and enhancing the ISSAMS system is provided. The Adriatic Sea’s representative data are shown, and they are contrasted with seismic and lab observations. These outcomes show how reliable and practical ISSAM is.
