A group of Jersey Shore mayors are calling for an "immediate moratorium" on offshore wind energy development until federal and state scientists can assure the public that ocean noise related to underwater seabed mapping, soil borings and other turbine construction activities poses no threat to whales.
The announcement followed news that another humpback whale had died off of the coasts of New Jersey and New York and washed ashore in Lido Beach, in Nassau County, New York, according to numerous reports.
"While we are not opposed to clean energy, we are concerned about the impacts these (offshore wind) projects may already be having on our environment," the 12 New Jersey mayors wrote in a joint letter to Washington officials.
The mayors include six from Ocean and Monmouth counties: Joseph Mancini of Long Beach Township, Samuel Cohen of Deal, Paul M. Kanitra of Point Pleasant Beach, William W. Curtis of Bay Head, Lance White of Mantoloking, and Jennifer Naughton of Spring Lake.
The Lido Beach whale marks the eighth whale to wash ashore on the beaches of New York and New Jersey in the past two months, the mayors said.
Last month, a dead humpback whale that appeared to have been struck by a ship washed ashore in Brigantine, according to the Marine Mammal Stranding Center.
Another humpback washed ashore in early January in Atlantic City, roughly two weeks after an earlier dead humpback washed ashore on the city's beaches.
Experts at the National Oceanic and Atmospheric Administration, or NOAA, said ship strikes and fishing gear entanglements are among the most common causes of death in humpback whales.
The agency said the unusually high number of whale deaths among humpbacks dates back to 2016, before offshore wind energy exploration began in the Atlantic ocean.
Cindy Zipf, executive director of the environmental organization Clean Ocean Action, said in a statement last month that offshore wind companies are being allowed by federal regulators to disturb and harm a certain number of whales and other marine animals during pre-construction and construction activity.
"Why should offshore wind get a pass on scrutiny to ensure marine ecosystem protection, especially for endangered and protected species?" she said in the statement.
Erica Staaterman, a bioacoustician at the federal Buruea of Ocean Energy Management's Center for Marine Acoustics, told reporters last month that there is no evidence that sound from high-resolution geophysical surveys, which are used to map sea floors for offshore wind farms, harms marine mammals. The surveys map the ocean bottom by bouncing sound waves.
Another environmental organization, the New Jersey League of Conservation Voters, insisted there was no evidence to blame offshore wind companies for the whales' deaths.
"While I am deeply concerned with the recent whale strandings, I also know we must base our decision making on science and data, not emotions or assumptions," Allison McLeod, policy director for the New Jersey League of Conservation Voters and a former professional mammal observer, said in a recent statement. "It is therefore irresponsible to assign blame to offshore wind energy development without supporting evidence."
Since 2016, 23 dead humpback whales have washed ashore in New Jersey, according to NOAA. Three of those happened in January, according to the agency.
