Efforts to stop wind turbines off the Atlantic coast have a new mascot: the whale.

A dozen New Jersey beach town mayors and several other groups now argue off-shore wind could be the cause of recent whale deaths and wind projects must be stopped while scientists investigate.

But those most vocal about their concern have been silent in recent years as whale strandings surged along the East Coast. Wind energy supporters and whale advocates say these groups and politicians appear to be using whales as pawns.

A Jan. 30 letter signed by 12 New Jersey mayors and a congressman Chris Smith (R-NJ), called for a moratorium on all offshore wind activity. Conservation advocates say the letter spreads speculation when scientists aren’t convinced whale deaths and offshore wind development are connected – and there’s good reason to believe they are not.

Whales and wind emerged in the headlines in January after a press conference Jan. 9 by two groups, Clean Ocean Action and Protect Our Coast New Jersey. They blamed the so-called “unprecedented” discovery of six dead whales along New Jersey and New York coasts on early-stage geotechnical surveys mapping the sea-floor for wind farms.

They advanced a festering concern that sound beams used in such surveys could harm nearby whales. Conservation groups and the Bureau of Ocean Energy Management generally believe that’s nonsense, in part because the type of sound used for wind turbine placement is much weaker than the stronger signals regularly used for other purposes such as oil and gas exploration.

Then the mayors’ letter made national news with its call for a moratorium on all offshore wind activity until federal and state agencies determine there’s no connection to recent whale deaths.

The cause has also been taken up by Fox News personality Tucker Carlson, who has aired a series of segments in which he called wind turbines DDT for whales.
