As the Biden administration expands its offshore wind projects as part of its goal to reach a carbon-free energy system, whales and other marine life may become collateral damage, according to new research.
Two independent studies measuring ocean wind turbine construction noise found that the sound emitted by vessels mapping the seafloor was significantly louder than estimated, and that noise protection for whales and other sea creatures during wind turbine pile driving doesn’t work.
Intense noise causes hearing loss in whales, other marine mammals, turtles, and fish, compromising their ability to navigate, avoid danger, detect predators, and find prey, according to scientific studies.
Robert Rand, an acoustics consultant with 44 years of experience, took underwater readings of the sonar survey vessel Miss Emma McCall off the coast of New Jersey. He also recorded acoustic readings of pile driving for Vineyards Wind 1, an offshore wind farm project under construction 15 miles south of Martha’s Vineyard.
