Abstract:

The purpose of this study was to record and analyze underwater sounds generated by a small hydraulic cutterhead dredge during maintenance dredging in the Stockton Deepwater Shipping Channel SDWSC, California. Of particular interest was determining 1 the sound frequency characteristics of the excavation process, 2 the received sound pressure levels at various distances from the source, 3 the predicted source level, and 4 ambient sound sources in the study area. These data will fill important knowledge gaps and inform future dredging project management decisions.
