2014, Subacoustech Environmental, Gunfleet Sands 3, Monitoring and Assessment of Operational Subsea Noise

Subacoustech Environmental Ltd has undertaken measurements of underwater noise at Gunfleet Sands 3 Demonstrator Wind Farm whilst the turbines were operational. Background noise measurements were undertaken in March 2013 prior to the operational phase of the wind farm. On 29th and 30th July 2014, underwater noise measurements were taken along transects extending away from the operational turbines. The measured data have been analysed and presented herein and shows that there has been negligible increase in the sound pressure levels compared to the levels measured prior to the turbines being made operational.
