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.
