Abstract
Since ocean sediments cause a loss of acoustic energy for acoustic wave propagation in shallow water, it is very important to investigate the acoustic properties such as the phase velocity and the acoustic attenuation of ocean sediments[1-4]. The acoustic properties of ocean sediments can be investigated in the laboratory using piston core sediments. In general, piston core sediments are longitudinally incised for acoustic measurements. Then, its physical properties can be changed by a disturbance in incision process. Since the acoustic properties of the sediments are related with the physical properties, they can be also changed. Therefore, it is important to measure the acoustic properties of the piston core sediment without any disturbance. This study introduces a PICAM (PIston Acoustic Measurement Core) system for measuring the acoustic characteristics without incision of the piston core sediment.
