Abstract

In this study, we assessed the volume backscattering strength (SV) of seabed sediments using a scientific echo sounder. The characteristics of the seabed sediments were determined using a sediment core sampler. Additionally, the SV and nautical area scattering coefficient (NASC) values for prey organisms were measured within the seabed sediments using the scientific echo sounder. Grain size analysis showed that the sediments in the surveyed area were mostly composed of sand and clay, and the NASC values for fish and zooplankton were relatively high in sediments composed of clay and silt.
