2013, Subacoustech Environmental Ltd., Gunfleet Sands 3, Pre-Operational Underwater Noise Survey

Description

This report presents the results of underwater noise measurements from a survey undertaken to in and around Gunfleet Sands Phase 3 Offshore Wind Farm. The Gunfleet Sands site is situated approximately 7 km off the Essex coast near Clacton-on-Sea.
Measurements were taken in order to provide an indication of the noise levels prior to the wind turbines being made operational. The data has been analysed to obtain noise levels in terms of unweighted levels and the dBht(Species) metric in order to provide an indication of existing levels of noise perceived by various species of animals in the water.
