  • Why whale deaths are dividing environmentalists — and firing up Tucker Carlson

    Why whale deaths are dividing environmentalists — and firing up Tucker Carlson

    [ad_1]

    There is no evidence the wind work and whale deaths are linked. But Clean Ocean Action, a 40-year-old nonprofit, believes the two things happening at once may be more than just a fluke.

    Real or rhetorical, the claim is stirring a new political debate.

    The group, which has been one of the few environmental organizations to criticize offshore wind, is using the whale deaths to push for a halt of offshore wind development until officials can figure out what is going on. Its message is spreading.

    Clean Ocean Action is now a strange bedfellow with conservative media figure Tucker Carlson, six Republican lawmakers in the New Jersey Legislature who represent coastal districts and Rep. Jeff Van Drew (R-N.J.), who co-chairs the congressional offshore wind caucus and is its only Republican member.

    Carlson is running a series of segments called “The Biden Whale Extinction.” In mid-January, he called wind energy “the DDT of our time” and a guest on the show said, without offering specific evidence, that wind developers’ survey ships were “carpet bombing the ocean floor with intense sound” that would confuse whales.

    Van Drew has called on Gov. Phil Murphy to pause offshore wind activity in New Jersey.

    “Since offshore wind projects were being proposed by Governor Murphy to be built off the coast of New Jersey, I have been adamantly opposed to any activity moving forward until research disclosed the impacts these projects would have on our environment and the impacts on the fishing industry,” Van Drew, whose South Jersey district includes several coastal counties, said in a statement.

    Murphy, like the president, has made offshore wind a key component of his clean energy plans.

    At least one moderate Democrat is expressing hesitation, too. New Jersey state Sen. Vin Gopal, who represents part of coastal Monmouth County, said he’s “very concerned” about any ties between wind and the whales.

    The political headache couldn’t come at a worse time for the offshore wind industry, which is already struggling to finance wind farms, including Ocean Wind 1, which would be New Jersey’s first.

    Biden has set a national goal of 30 gigawatts of offshore wind by 2030, enough energy to power 10 million homes, and Murphy set a state level goal of 11 gigawatts by 2040. To achieve these goals, developers in New Jersey and other states will need to quickly install hundreds of giant wind turbines miles off the coast. So far, just one major project in the region, the South Fork wind farm in New York, has broken ground.

    Clean Ocean Action Executive Director Cindy Zipf said she has no evidence to tie the whale deaths to offshore wind, beyond that there is an unprecedented number of whales dying on beaches and an unprecedented amount of offshore wind work getting underway. But there’s also no evidence to prove there isn’t a connection.

    For years, Zipf’s group has argued the federal government has skimped on monitoring new wind infrastructure planned for the ocean and isn’t certain of the effect sonic mapping of the ocean floor and an increase in ship traffic will have.

    Wind supporters from the New Jersey chapters of the Sierra Club and League of Conservation Voters say talk of a connection with whales is baseless and no reason to stop the development of clean energy. They say an already-warming ocean is a known threat to whales and clean power from wind energy could help stop climate change.

    Federal regulators from the Bureau of Ocean Energy Management gave offshore wind supporters a hand by telling reporters last week that there is no evidence construction would exacerbate or compound whale deaths. The kind of sound surveys being done by offshore wind companies has not been linked to stranded whales, they said.

    BOEM has been monitoring an unusual number of whale deaths since 2016 and found that about 40 percent of the animals they examined were struck by some ship or entangled in fishing gear. Those sorts of threats are old but may become more common because whales are following their prey closer to shore — something that may be a result of climate change.

    There are no wind farms off the New Jersey coast yet, though surveys of the seafloor using sound have been conducted.

    Worries that sonic mapping might be affecting whales’ navigation are overblown, said Erica Staaterman, an expert at the federal government’s Center for Marine Acoustics. Staaterman said during the call with reporters that there’s a “pretty big difference” between the relatively brief and targeted sound mapping used by offshore wind and the very loud sounds used by oil and gas companies to take measurements deep beneath the seafloor.

    She didn’t make it explicit, but there is a political point there: if conservative media is so concerned about the whales, why are they opposed to offshore wind but pushing offshore drilling?

    Because it isn’t clear why the whales are dying, the absence of evidence is being used as evidence of regulatory absence.

    “It doesn’t seem to me that they have conducted very much review of anything, which is what we’re calling for,” Zipf said in an interview after the media briefing by federal regulators.

    Other environmental groups like the Sierra Club have been scrambling to tamp down the speculation and undo the notion that offshore wind is killing whales. At the same time, they’re trying to point out hypocrisy among offshore wind’s foes.

    “I wouldn’t call for commercial shipping to stop because I know it’s unreasonable. It’s trade. I know it’s not going to stop,” New Jersey Sierra Club Director Anjuli Ramos-Busot said in an interview. “So I find it unreasonable to call for the pause or moratorium on offshore wind — which is going to save us all.”

    Last year, the East Coast’s largest port, the Port of New York and New Jersey, saw nearly 3,000 ships come and go, a figure that vastly undercounts all the ocean traffic in the region and dwarfs the number of vessels that have anything to do with offshore wind.

    In New Jersey, Murphy’s offshore wind hopes are already meeting headwinds because of basic economics.

    Orsted, the Danish developer behind what would be New Jersey’s first offshore wind farm, said late last year it’s worried about making money on the project and other large projects approved in other states.

    The state Board of Public Utilities, which controls Orsted’s return on the project, has received well over 100 public comments since December opposing offshore wind and citing whale deaths.

    Wind supporters point out that some of the opposition to offshore wind is coordinated and involves misinformation supported by fossil fuel interests.

    At a press conference organized by the New Jersey League of Conservation Voters and the Sierra Club, Jody Stewart of the New Jersey Organization Project, a group formed after Hurricane Sandy to help with recovery and to protect shores from extreme weather, said if there is any investigation it should be of the coordinated industry campaign to “stir up opposition among locals.”

    “They’re the ones taking this narrative of whales dying because of offshore wind and running with it — not regular people, not people who live here,” she said.

    That’s a harder criticism to pin on Clean Ocean Action, which was founded to fight ocean dumping and does beach cleanups, opposes offshore drilling and helped block liquefied natural gas facilities along the New Jersey coast.

    There is some evidence, from inland waterways, that the federal government has advanced wind-related projects without fully exploring the threat new shipping routes pose to wildlife.

    Last summer, the Delaware Riverkeeper Network alleged federal fisheries officials ignored how construction and operation of a New Jersey port being created to help the wind industry could harm fish, especially a rare type of Atlantic sturgeon in the river. In an email later obtained by the group, federal officials appeared to acknowledge they hadn’t used the best available information about how boats might kill river sturgeon. But that didn’t halt construction at the wind port.

    Privately, offshore wind supporters wonder if Clean Ocean Action’s argument is more about NIMBYism than environmentalists.

    Zipf rejects this.

    “Clean Ocean Action’s mission is solely to protect the ocean, that is our mission, and, you know, being a voice for the ocean oftentimes makes us a lone voice for a period of time until others understand the scope and the threat to the ocean is a threat to us all,” she said.

  • A rare glimpse inside Britain’s secret vault of whale skeletons

    A rare glimpse inside Britain’s secret vault of whale skeletons

    [ad_1]

    Behind a 10-foot tall door, in a secret location, lies a treasure trove of bones. Some of the biggest bones are laid out on storage units made of scaffolding, others are stacked against each other on racks – rows and rows of specimens. The smallest are tucked into drawers of faded-yellow metal cabinets. A selection of skulls lies on a low table; crudely stuffed animals hang from the painted breezeblock walls. Everything is carefully labelled.

    This vast room houses the Natural History Museum’s cetacean collection – a globally unique hoard of 6,000 whales, dolphins and porpoises. The artefacts are so enormous and irreplaceable, they’re housed at a secret location away from the main museum building.

    It is the most complete collection of these creatures in the world, containing specimens of 90% of the world’s 90 cetacean species, including 24 from UK waters.

    “It’s visually stunning, yes, but also incredibly scientifically and culturally significant,” says Richard Sabin, the Natural History Museum’s principal curator of mammals. “You’re looking at one of the best research collections of its kind in the world – what makes it unique is the species representation.”

    The room’s cool temperature and low humidity have been designed to preserve its precious contents, from bones to baleen. As well as specialist biology and evolutionary history, the collection enables scientists to look at how everything from DNA to hormones vary across time and space.

    Crucially, collections such as this (one of only five of its kind in the world), may provide clues about how whales, dolphins and porpoises might respond to future stresses such as the climate crisis. “These institutions are like reservoirs of scientific information,” Sabin says. “[Not only can we] look back in time and see how things have changed, we can plan for the future. That’s one of the greatest uses for this collection.”

    The Natural History Museum has been officially recording whale and dolphin strandings since 1913, and many remains end up here after postmortem. In addition to 800 strandings, there are remnants from whaling expeditions and archaeological finds, some stretching as far back as 500 years.

    One of the largest occupies a big glass cabinet, which dominates the main gangway. Here, the Thames whale lies in state: the northern bottlenose whale that became something of a celebrity in 2006 when it swam upriver, stranded on the sand in front of crowds of Londoners, and despite efforts to save it, died.

    Another was uncovered in 2010 as builders dug new jetty foundations at Greenwich, in London. Huge bones sticking up out of the muddy Thames foreshore were identified by Sabin as a headless North Atlantic right whale. “The skeleton was at right angles to the flow of the river, with the tail facing up the slope of the beach … that’s not a natural stranding position,” he says. It had likely been pulled up by the tail, then beheaded for its precious baleen, once used to make corsetry and other garments.

    Carbon dating pinpointed the Greenwich whale’s death to between 1580 and 1660, while cut marks on the bone surfaces indicated “defleshing”. “Everyone took what they could from it before the skeleton collapsed under its own weight,” says Sabin. “This animal is now the largest, oldest dated specimen of this species anywhere in the world – this skeleton can tell us a lot.” For example, its DNA could reveal whether limited genetic diversity, climate or competition contributed to right whales’ vulnerability before commercial whaling.

    Elsewhere, dozens of jaw bones are stacked up. One lower jaw of a male sperm whale is abnormally twisted into a corkscrew shape: this unusual specimen came from an Antarctic whaling ship in 1959. At first glance, the jaw seems to make feeding an impossibility. But the back teeth, worn down to “stumpy pegs”, indicate that this whale was successfully eating giant squid, thanks to its highly specialised echolocation and efficient suction feeding.

    Sabin, still fascinated by each revelation after 30 years as curator, is particularly proud of the insight garnered from crates containing 800 baleen plates from a blue whale stranded in 1891. Nicknamed Hope, the young female died on a sandbank near Wexford, Ireland. Now, her 25m-long skeleton is on display in the museum’s Hintze Hall.

    By analysing her baleen – layers of keratin that are used to trap krill – scientists at Southampton University learned, using a technique known as stable isotope analysis, that in summer she fed near Norway, Iceland and Greenland to accumulate her fatty blubber layer, then in winter migrated south to the Azores and west Africa for the breeding season.

    What’s more, visible ridges on this hard, black baleen represent the annual peaks and troughs of her feeding cycle, and scientists found that about 18 months before she died she remained in the south for 10 months – probably to have a calf. In the Wexford archives, Sabin found that violent storms were recorded in the days before she beached, storms that could have steered her off course.

    In addition, researchers at Baylor University in Texas analysed her earwax and found her pregnancy hormone progesterone levels were elevated during the last 18 months of her life for 10 months – the blue whale gestation period. “Suddenly we have this rich information about the life of an individual whale that was living in 1890,” Sabin says.

    With Sabin’s help, the same Texas team studied persistent chemical pollutants and the stress hormone cortisol in plugs of whale earwax to reveal how, between 1870 and 2016, human activities from commercial whaling, war, industrial pollution and shipping noise, have caused physical stress responses in whales.

    “This information is written into the tissues of these animals,” Sabin says. “Suddenly, in the past 20 years, we’ve developed technologies that mean we can liberate information from this kind of material. We can take single hairs and do genome DNA testing or stable isotope analysis, which gives info about diet, distribution, movement, indicators.”

    The museum is entering an era of digitisation, uploading 3D surface scans or CT scans of specimens to a free online database. It allows researchers anywhere in the world to collaborate. “This collection gives these specimens a life after death,” says Sabin. “What are we going to learn in the future?”
