An effort to create ‘carbon-free energy’ is resulting in the injury and death of sea creatures, including protected ones.
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.
In his pile-driving report, published March 28, Mr. Rand found that even the most advanced sound-dampening technologies didn’t adequately control harmful noise. The pounding was just as loud as seismic air gun arrays used for oil and gas exploration, long known to cause injury, hearing loss, and behavioral changes in fish and marine mammals.
Furthermore, the noise made by the construction vessel itself, which is not monitored, was almost as loud as the pile driving. Mr. Rand found that the standard formula used by the National Marine Fisheries Service to calculate how noise, over a period of time, affects a mammal’s hearing, significantly underestimates the sound levels experienced by dolphins and whales.
“These are real data,” Mr. Rand, who testified at a Congressional field hearing on January 20, told The Epoch Times. “I measured it. This is not a computer model. This is not a political press release. These are data.”
Many environmentalists fear that noise related to ocean wind farm construction is contributing to “unusual mortality events” affecting whales. From 2016 through April this year, 220 humpback whales have died, according to data collected by the National Oceanic and Atmospheric Administration (NOAA).
