Description
Summary:Underwater noise is a growing concern to conservation and stock management efforts to which supra-national organizations (e.g., OSPAR or the European Union) and governments (e.g., USA) are beginning to respond by building catalogues of the noise introduced in the marine environment by human activity. Rock placement is a construction activity for which there is scarcely any data available. In order to fill the knowledge gap, opportunistic recordings were taken while the Gardline Mk 3 hydrophone array was deployed for Passive Acoustic Monitoring and mitigation for marine mammals. The recordings were analyzed for their spectral and temporal characteristics, a correlation analysis between the amount of rock placed and the intensity of sound produced was made, and the suitability of the hydrophone array for the collection of this type of data was assessed.
