First, a North Atlantic right whale, a critically endangered species, washed ashore in Virginia. Then, a humpback floated onto a beach in New Jersey. Not long afterward, a minke whale, swept in on the morning tide, landed on the Rockaway Peninsula in New York City.
And that was in just a single week in February.
In all, 23 dead whales have washed ashore along the East Coast since early December, according to the National Oceanic and Atmospheric Administration. The pace of the deaths is worrisome to federal scientists, even if the total numbers are below some prior years.
Most of the fatalities have been humpbacks, and post-mortem examinations have suggested that ship strikes are probably the cause of many of the deaths.
Scientists believe the mortality rate may be tied to an unlikely confluence of factors.
The population of humpbacks, hunted legally until 1985, has rebounded, thanks in part to decades of efforts to clean the Atlantic Ocean and heavily polluted tributaries such as the Hudson River. As the climate changes and oceans warm, whales and a favored prey, menhaden, are migrating and feeding in new locations, often closer to shore.
Online pandemic buying habits are also fueling a record-setting surge in cargo shipments that last year made ports in New York and New Jersey the nation’s busiest. Much of the merchandise is now toted on far-bigger ships — some of which have altered their routes to help alleviate the supply-chain chaos that last year left some store shelves bare.
As a result, more whales appear to have found themselves in the direct path of more ships.
“When the whales are in these channels,” said Paul Sieswerda, executive director of Gotham Whale, a New York City-based whale research group, “you have to cross your fingers and hope there are no collisions.”
This winter’s quick succession of stranded whales also coincides with work being done in advance of the installation of roughly a dozen large offshore wind farms from Massachusetts to Virginia. Opponents of offshore wind have said that the sonar used by energy companies to map the ocean floor or the noise from seabed rock sampling might be contributing to the whale deaths, although NOAA and the Marine Mammal Commission say there is no evidence that this is true.
For more than half of all whales found stranded, investigators are not able to determine a definitive cause of death. Most of the animals are too decomposed; others may have died of infections that are impossible to detect or differentiate from the bacteria that quickly begins to form on dead tissue.
Some of the loudest voices drawing attention to the uptick in whale deaths are longtime opponents of offshore wind energy, who have found in the gruesome images of rotting whale carcasses a new 40-ton mascot.
Several local groups have found common cause with national organizations that have accepted funding from the fossil fuel industry, including the Caesar Rodney Institute, a right-leaning nonprofit that David Stevenson helps to lead.
Stevenson, who opposes offshore wind farms, is not convinced that it is greenhouse gases that have caused Earth to heat up, contradicting settled science. He believes offshore wind energy will be too expensive, and he recently founded the American Coalition for Ocean Protection, which now has chapters in coastal communities in New Jersey and New York.
“If an emotional response is what it takes,” he said about concern for the whales, “I’m not going to turn them down.”
Over the past month, Republican members of Congress, conservative talk-show hosts and dozens of Jersey Shore mayors have called for an immediate moratorium on wind-energy projects.
“It’s not reasonable that it’s not going to cause real ecological damage,” said Cindy Zipf, director of Clean Ocean Action in New Jersey, which is calling for additional study before offshore wind projects receive final authorization.
But environmental protection organizations have largely supported wind energy. Thirteen such groups in New Jersey have reiterated support for offshore wind, a pillar of President Joe Biden’s ambitious goals for reducing carbon emissions and combating climate change.
“The organizations that are serious about protecting marine life recognize there are trade-offs,” said Matthew Eisenson, who runs a legal defense initiative at the Sabin Center for Climate Change Law at Columbia University. “Climate change can impact marine life — and we need renewable energy to mitigate climate impacts.”
