Distance dependent study on noise emissions due to pile driving in recent offshore construction projects in the German North Sea

Abstract:
Pile driving is one of the most intensive anthropogenic noise sources in the marine environment. Each foundation pile may require up to a few thousand strokes with high hammer energy to drive to the embedded depth. Scientific evidence shows that impacts on the marine environment have to be anticipated if no mitigation measures are applied. Pile driving events analysed here, occurred during a recent foundation construction phase in a wind farm cluster with monopile installation positions located in water depths between approximately 38 and 40 m. Here, we evaluated the acoustic measurements in a standardised monitoring distance of 750 and 1500 m to each of the pile driving locations and at a temporary fixed monitoring station (data resource: MarinEARS).
