Abstract:

Alaska DOT&PF and JASCO Applied Sciences partnered to characterize underwater noise from pile driving activities to inform the assessment of the potential impact of such noise on marine mammals. JASCO measured underwater sounds at the Kake, Auke Bay, Kodiak, and Ketchikan ferry terminals during ferry terminal improvement construction projects and characterized sound levels associated with pile extraction, vibratory pile driving, impact hammer pile driving, and rock socket drilling. Source levels and transmission loss coefficients were determined for each activity at each site. Background sound levels were also characterized at each site for comparison with pile driving sounds. Distances from the piles to behavioral disturbance sound pressure level thresholds were calculated for each source type and compared with source and environmental characteristics. Distances to injurious cumulative sound exposure level thresholds were calculated based on frequency-weighted data to account for hearing sensitivity of marine mammal groups.
