Research Abstract

In coastal area, Sargassum spp., Zostera spp. and Laminaria spp. forms dense vegetation community, which are called as seaweed bed, seagrass bed and kelp bed. In this study, we estimated the characteristics and the wave shapes of acoustic intensity of these beds, and then we developed the discriminate method of these beds by acoustic technique using the characteristics. In the result, it was suggested that the discrimination of the beds is possible using a two-stage approach. The first stage is the discrimination of the area backscattering (Seaweed bed; -33.3~-57.0 dB, Seagrass bed; -39.2~-66.1 dB, Kelp bed; -59.8~-74.3 dB). In the second stage is the discrimination of the wavelet coefficient of Lv. 4 (Seagrass bed; 12000-39000, Kelp bed; 3000-12000). This method may allow better biomass estimation of these beds by acoustic technique.
