This data series contains reports and data files, in various formats, of this assessment. Since the Environmental Statement (ES), 2012, was completed, a more detailed assessment of the engineering requirements for the piling operation has been carried out. This includes the hammer energies of noise on marine mammals at the site in light of this new information, in the context of the predictions made previously for the ES. The work presented takes into account more detailed site investigations and updated pile drivability assessment and engineering requirements. This updated underwater noise assessment is based on realistic expected worst case scenarios that have reduced significantly from those outlined in the ES. This document will highlight differences will highlight differences between this assessment and the ES and place them into context.

These source levels were then input into an acoustic propagation model – which took into account sediment, bathymetry and water column properties at the site – to produce noise maps of received levels throughout the Moray Firth. These predictions were combined with noise exposure thresholds for marine mammals (harbor porpoise, bottlenose dolphins, and grey and harbor seals) obtained from the peer-reviewed literature. Effect zones were then mapped for temporary and permanent auditory impairment.
