There is nothing yet linking the Block Island Wind Farm to the death of humpback whales, but that hasn't stopped anti-wind and conservative groups from making the connection.
The recent stranding and
death of a 32-foot juvenile humpback whale in Jamestown triggered speculation,
and in some cases unsubstantiated assertions, that noise from the first U.S.
offshore wind farm caused this and other whales to die.
As the HuffPost recounts, the claim was first made by the conservative website Daily
Caller and through a conservative news wire has been republished and rewritten
in various forms by national new outlets such as The Blaze and through local
anti-wind groups and press reports that inferred the link. The Newport Buzz names the five-turbine wind farm as the prime suspect.
None of the anti-wind
articles offer a scientist as a source for their claims or research that
deduces that the wind farm, owned by Providence-based Deepwater Wind, caused
the whale to beach itself.
UPDATE: The RI Coastal Resource Management Council issued this statement on the allegations that the death of the whale was connected to the Block Island wind turbines:

According
to information compiled by the Bureau of Ocean Energy Management (BOEM), there
has been no scientific evidence collected to-date of any whales being injured
or stranded due to offshore wind activities.
Observed data collected shows that
the operation sounds from offshore wind turbines generate sounds that are
relatively low (approximately 134 decibels at the Block Island Wind Farm site)
when compared with other sounds. For comparison, rainstorms range in the 100 to
120 decibel level, and fishing vessels create sounds that range from 150 to 190
decibels.
Baleen
whales do not use sonar to navigate or feed, and are classified as
low-frequency (10 Hz to 31 kHz) vocalizers, and generally produce grunts, moans
and pulse trains to communicate. The operational underwater noise measured at
the Block Island Wind Farm can possibly be heard by whales over short
distances, but is expected to not be heard beyond a few hundred meters from the
foundation.
Scientific
literature based on data collected in the United Kingdom states that
“underwater noise from operation wind facilities is not considered
significant.”
BOEM
said it plans to continue to monitor and assess potential impacts related to
the construction and operation of wind farms on marine life, specifically
whales, through the Environmental Studies Program and data collected from
lessees and state and federal partners.
Only the HuffPost quoted
a marine biologist, at Cornell University, who said wind turbines contribute to
the cacophony of underwater noise from boats, ships and barges, and that this
mix of manmade noise — which can also include sonar, fossil-fuel drilling, and
military exercises and testing — can disorient but isn't likely to kill marine
life.
Jeff Grybowski, CEO of
Deepwater Wind, told ecoRI News that the five turbines are simply not to blame.
"There is absolutely no evidence that the wind farm is in any way
connected to this whale," he said. "The wind farm does not create any
special risks to marine life. In fact, marine life is thriving near the
project.”
As part of its approval
process, the wind farm and its transmission system received a finding of no significant impact for acoustic impacts by the federal Bureau
of Ocean Energy Management.
Deepwater Wind has a lot
riding on the emerging offshore wind industry.
The wind and solar developer has
several wind farms in the works between New York and Massachusetts. The
wind-rich region has also attracted developers from Norway, Denmark and other
countries with established wind industries.
Here's what is known
about the death of the Jamestown humpback whale:
A necropsy was performed
by Mystic Aquarium & Institute for Exploration at the site of the stranding
at Beavertail State Park. Tests to determine the case of death were sent to a
laboratory and aren't expected for weeks.
The Rhode Island
Department of Environmental Management (DEM) won’t say where the carcass was
buried. In 2005, a 50-foot finback whale found dead on Newport’s Brenton Point
State Park was buried at the Great Swamp Management Area in West Kingston.
There has been a spike
in humpback whale deaths along the East Coast between North Carolina and Maine.
Since January, 48 humpbacks deaths have been reported.
Although ship strikes
and entanglements with fishing gear are the main killers of humpback whales,
the recent increase in humpback deaths has been classified as an unusual mortality event by the National Oceanic and Atmospheric Administration
(NOAA).
An investigative team
will review data, study samples from future strandings and decide what, if any,
action to take.
NOAA also lists sonar,
military testing, resort development and increased boat traffic as threats to
humpback whales and their habitat.
The Jamestown whale
death coincides with a surge in humpback whale sightings between mainland Rhode
Island and Block Island, according to DEM. The whales are likely drawn to a
growing food supply — the small, eel-like forage fish, called the American sand
lance — DEM said.
Humpback whales are
protected under the federal Endangered Species and Marine Mammal Protection
acts. They grow to about 60 feet in length and have a lifespan of about 50
years.
They are the most
popular marine mammal for whale watching in New England, because of their habit
of breaching and slapping the water surface with their tails.
