2012, Subacoustech, Ormonde, Measurement and Assessment of Underwater Noise

A series of underwater acoustic measurements undertaken in and around the Ormonde Wind Farm on the 20th and 21st June 2012. The purpose of the measurement programme was to characterise any increase in the ambient subsea noise due to the presence of the operational wind farm and to assess the range over which any increase in noise occurred.Underwater noise was recorded using specialist equipment developed by Subacoustech Environmental Ltd. This measured the underwater sound to levels well below sea state zero noise, and over the frequency range that covers both the requirements to characterise anthropogenic noise in the ocean and the hearing response range of species of fish and marine mammals.
