Infrasonic acoustic energy produced by offshore wind turbine energy generation may interfere with bird and cetacean navigation cues

Abstract: Offshore wind turbine farms are being planned and installed throughout the coastal areas of the global ocean. Noise concerns from these activities are typically framed within frequency bands of concern defined by governmental regulatory agencies (NMFS-OPR-59, 2018). A less considered noise source are the various infrasonic noises generated by large rotating blades in a pressure-dynamic medium. These noises include the infrasonic “thumps” generated by the motion of the turbine blades as they intersect the “stagnate wind area” on the . . .
