This research study observes the effects of offshore wind farm noise on marine mammals and fish. The noise created during the installation of offshore wind farms has been discussed intensively with the public and the scientific community. Especially the noise created during pile-driving operations involves sound pressure levels that are high enough to impair the hearing system of marine mammals near the source and disrupt their behaviour at considerable distance from the construction site. Measurements were taken during construction in the German Bight and near turbines in Sweden. Sound levels at various distances from the source were calculated and zones of noise influences were assessed based on published data. For harbour porpoises and harbour seals, the zone of audibility for pile-driving will most certainly extend well beyond 80 km, perhaps hundreds of kilometres from the source. Cod and herring will be able to perceive piling noise at large distances, perhaps up to 80 km from the sound source. Dab and salmon might detect pile-driving pulses also at considerable distances from the source

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Since the beginning of the planning and installation of offshore wind farms, the possible impacts on marine mammals and fish have been discussed intensively within the public and the scientific community. Especially the noise created during pile-driving operations involves sound pressure levels that are high enough to impair the hearing system of marine mammals near the source and disrupt their behaviour at considerable distance from the construction site. Previous investigations also indicated that the construction phase will have considerable effects on fish species common in northern European waters. The goal of this study was to provide a further assessment on the effects of offshore wind farm related noise on selected marine mammal and fish species. Measurements of pile-driving noise were obtained as peak sound pressure levels and sound exposure levels in 1/3 octave bands from a jacket-pile construction in the German Bight. Operational noise was measured in peak sound pressure levels and equivalent sound pressure levels in 1/3 octave bands in 110 m distance from a 1.5 MW turbine in Sweden. Based on these measurements, sound levels at various distances from the source were calculated and zones of noise influences were assessed based on published data. |
