Assessment Of Sub-sea Noise And Vibration From Wind Turbines And Its Impact On Marine Wildlife

The report presents a significant body of underwater noise measurements taken in the period April 2003 to January 2004 at operational and construction stage windfarm sites in the UK. A detailed analysis of the measurements has been made which indicates the spatial, temporal and statistical properties of the noise. An estimation of the likely behavioural and physical effects on a selection of the most common species of fish and marine mammals is also presented using both conventional analysis and the dBht (species) scale.
