Abstract

Seabed sediments are becoming a significant information for marine development and understanding the fishing environment. In this study, the backscattering strength according to the particle size of the seabed sediment was analyzed. The soil sample collection of this study was conducted with a gravity corer, and sound data collection at the station was performed using a 38kHz a scientific echosounder. Eco-view (8 versions) was used as the collected sound data. At the station where the Sand ratio was high, a high reflection strength was observed, and at the station where the Silt ratio and Clay ratio were high, a low reflection strength was found. Based on the reflection intensity results, it can be seen that the acoustic reflection intensity is high in the order of Gravel, Sand, Silt, and Clay.
