Abstract
The characteristics of acoustic wave propagation in marine sediments are influenced by the temperature. It was reported that the longitudinal wave velocity in marine sediment varies with the temperature. However, the investigation using acoustic model for marine sediment has not been done in detail. Also, the study on the temperature dependence for the attenuation is not seemed to be sufficient. In this study, the temperature dependence for the longitudinal wave velocity and the attenuation of the water-saturated glass beads as the sediment model has been measured using UPER (Ultrasonic Pulse Echo Reflectometer). The measured results and the calculated results using the Biot-Stoll model are compared and investigated.
