November 16, 2023 — More research is needed to determine whether offshore wind turbines will affect North Atlantic right whales’ food source around the Nantucket Shoals, scientists have concluded in a new report. And it may be challenging to divorce those impacts from those brought by climate change.
Right whales, a critically endangered species, are using the shoals, an area of shallow waters, for breeding and feeding. The shoals lie east of several planned offshore wind projects. Last year, federal scientists expressed concern that wind projects could disrupt right whales’ food supply: dense collections of tiny organisms, called zooplankton.
In response, the Bureau of Ocean Energy Management, the lead agency on offshore wind development, convened an independent committee in April to evaluate what impacts wind turbines might have on the shoals and the whales’ prey.
However, due to knowledge gaps and a lack of research on this side of the Atlantic, the answers remain elusive.
“The studies available about the effects and implications of wind farms on local ecosystems are not sufficient to say with absolute certainty whether the turbines would have effects,” said committee chair Eileen Hofmann, a professor at Old Dominion University and chair of the scientific committee, which worked under the National Academies of Sciences.
