New England’s historical and cultural identity is inextricably linked to the ocean that laps at nearly 6,200 miles of coastline. And the region’s ocean waters are warming, and not just a little.
The above chart shows just how much the ocean has warmed over the past 65 years and, due to the accumulation of greenhouse gases, the heat dumped into the ocean has doubled since 1993. It is even more concerning that ocean warming has accelerated since 2010.
The world’s oceans, in 2021, were the hottest ever recorded by humans.
The findings of the data from the National Centers for Environmental Information (NCEI), which is part of the National Oceanic and Atmospheric Administration (NOAA), have been confirmed by Australia’s Commonwealth Scientific and Industrial Research Organization, China’s Institute of Atmospheric Physics, and the Japan Meteorological Agency’s Meteorological Research Institute.
The news for New England is worse, as the ocean here is heating up faster than that of the rest of the world.

The Gulf of Maine Research Institute announced that between September and November of last year, the warmth of inlet waters adjacent to Maine and northern Massachusetts was the highest on record.
“This year [the Gulf of Maine] was exceptionally warm,” said Kathy Mills, who runs the Integrated Systems Ecology laboratory at the Gulf of Maine Research Institute. “I was very surprised.”
The Gulf of Maine is warming faster than 96 percent of the world’s oceans, increasing at a rate of 0.1 degrees Celsius (0.18 degrees Fahrenheit) annually over the past four decades.
The increased concentration of greenhouse gases in the atmosphere traps heat in the air. The air in contact with the ocean transfers heat to the ocean, increasing what is called the ocean heat content (OHC).
The first measurements of ocean data were taken on Capt. James Cook’s second voyage (1772-1775). Although not very accurate, those measurements were among the first instances of oceanographic data recorded and preserved.
Today, ocean measurements are taken by a variety of modern instruments deployed from ships, airplanes, satellites and, more recently, underwater robots. A 2013 study by John Abraham, a professor at the University of St. Thomas, contains an interesting historical overview of ocean measurements.
Abraham’s study used data from new instruments, such as expendable bathythermographs and Argo floats. The Argo program is an array of more than 3,000 autonomous floats that return oceanic climate data and has advanced the breadth, quality and distribution of oceanographic data.
As heat accumulates in the Earth’s oceans, they expand in volume, making this expansion one of the largest contributors to sea-level rise.
Although concentrations of greenhouse gases have risen steadily, the change in ocean-heat content varies from year to year, as the chart above shows. Year-to-year changes are influenced by events, such as volcanic eruptions and recurring patterns such as El Niño. In fact, in the chart one can detect short-term cooling from major volcanic eruptions of Mounts Agung (1963), El Chichón (1982) and Pinatubo (1991).
The ocean’s temperature plays an important role in the Earth’s climate crisis because heat from ocean surface waters provides energy for storms and influences weather patterns.

If present trends continue, by the end of the century, the cost of global warming could be as high as $1 billion annually for Providence County, R.I., alone, according to data from a 2017 research paper. That’s about $1,600 per person per year. Every year.
But, before we talk about the future, let’s discuss the economic damage that has already occurred in Rhode Island because of warming temperatures.
Like rich Bostonians, Rhode Island’s lobsters have moved to Maine. In 2018, Maine landed 121 million pounds of lobsters, valued at more than $491 million, and up 11 million pounds from 2017. It wasn’t always so.
Andrew Pershing, an oceanographer with the Gulf of Maine Research Institute, has noted that lobsters have migrated north as climate change warms the ocean. In Rhode Island, for instance, days when the water temperature of Narragansett Bay is 80 degrees or higher are becoming more common. From 1960 to 2015, the bay’s mean surface water temperatures rose by about 3 degrees Fahrenheit, according to research data.
A 2018 research paper Pershing co-authored said ocean temperatures have risen to levels that are favorable for lobsters off northern New England and Canada but inhospitable for them in southern New England. The research found that warming waters, ecosystem changes, and differences in conservation efforts led to the simultaneous collapse of the lobster fishery in southern New England and record-breaking landings in the Gulf of Maine.
He told Science News last year that with rocky bottoms, kelp and other things that lobsters love, climate change has turned the Gulf of Maine into a “paradise for lobsters.”
However, in the formerly strong lobster fishing grounds of Rhode Island, the situation is grim. South of Cape Cod, the lobster catch fell from a peak of about 22 million pounds in 1997 to about 3.3 million pounds in 2013, according to the 2018 paper published in Proceedings of the National Academy of Sciences.
Lobsters provide interesting lessons on the impact of the climate crisis.
A conservation program called V-notching helped protect Maine’s lobster population. “Starting a similar conservation program earlier in southern New England would have helped insulate them from the hot water they’ve experienced over the last couple of decades,” Malin Pinsky, a marine scientist with Rutgers University, told Boston.com two years ago.
Rhode Island’s lack of conservation efforts in the face of the growing climate crisis contributed to the collapse of its lobster fishery. Doing nothing or too little in the face of a changing climate can be economically devastating.
Another existing, and growing, threat to the economic health of Rhode Island comes from Lyme disease, which has increased by more than 300 percent across the Northeast since 2001. A changing climate is a big reason why. There is a growing body of evidence showing that climate change may affect the incidence and prevalence of certain vector-borne diseases such as Lyme disease, malaria, dengue, and West Nile fever, according to a 2018 study.
Chronic Lyme disease is more widespread and more serious than generally realized. There are some 20,000 cases annually in the Northeast and each averages about $4,400 in medical costs. Most Lyme disease patients who are diagnosed and treated early can fully recover. But, an estimated 10 percent to 20 percent suffer from chronically persistent and disabling symptoms. The number of such chronic cases may approach 30,000 to 60,000 annually, according to a 2018 white paper.
As the lobsters and the ticks vividly demonstrate, prevention is cheaper than cure. The longer we wait, the more painful, and expensive, the consequences will be.
The aforementioned 2017 study Estimating Economic Damage from Climate Change in the United States by world-renown economists and climate scientists projects the impact of climate change for every county in the United States. The results for Rhode Island and its neighbors are summarized in the map to the right, which depicts the estimated economic damage, in millions of dollars annually for each county in Rhode Island, Massachusetts, and Connecticut.
The data make clear that the economic damage will not be uniformly distributed. Some counties, such as Providence County, will be hit much harder than others. It also may seem that the southern counties will suffer much less. But that isn’t quite true, as graph below shows. The damage per person per year is projected to be substantial.
The total economic damage to Rhode Island, by 2080, could result in a 2 percent decline in gross domestic product (GDP). To put that in context, during the Great Recession of 2008-2010, there was only one year of GDP decline: minus 2.5 percent in 2009. By 2010, GDP had bounced back to positive growth, at 2.6 percent.
Therefore, the impact of a 2 percent hit to Rhode Island’s GDP from the climate crisis could look like the recession of 2009, only becoming permanent, continuing year after year. Also, it won’t all happen in 2080, the damage will continually get worse.
The economic damage is projected to come from more frequent and intense storms; sea-level rise; increased rainfall resulting in more flooding; higher temperatures, especially in the summer; drought that leads to lower crop yields; increased crime.
In addition, essential infrastructure will be impacted, including water supplies and water treatment facilities. Ecosystems, such as forests, rivers, lakes and wetlands, will also suffer, and that will impact human quality of life.
In the coming two weeks, we will describe how each Rhode Island county faces different levels of the above threats. As a result, each county needs to develop appropriate mitigation strategies.
The damages from the climate crisis will place major strains on public-sector budgets. However, much of the economic damage will be felt by individuals and families through poorer health, rising energy costs, increased health-care premiums, and decreased job security.
As always, prevention is cheaper, and more effective, than cure. Inaction on climate change will be the most expensive policy option.
The lobsters should teach us a valuable lesson: conservation measures based on sound scientific and economic principles could have helped mitigate losses caused by the climate crisis.

Progression of expected wind turbine evolution to deeper water
The forthcoming report from the federal Bureau of Ocean Energy Management (BOEM) on the cumulative environmental impacts of the Vineyard Wind project will determine the future of offshore wind development.
BOEM’s decision isn’t just the remaining hurdle for the 800-megawatt project, but also the gateway for 6 gigawatts of offshore wind facilities planned between the Gulf of Maine and Virginia. Another 19 gigawatts of Rhode Island offshore wind-energy goals are expected to bring about more projects and tens of billions of dollars in local manufacturing and port development.
Some wind-energy advocates have criticized BOEM’s 11th-hour call for the supplemental analysis as politically motivated and excessive.
Safe boat navigation and loss of fishing grounds are the main concerns among commercial fishermen, who have been the most vocal opponents of the 84-turbine Vineyard Wind project and other planned wind facilities off the coast of southern New England.
Last month, Rhode Island state Sen. Susan Sosnowski, D-New Shoreham and South Kingstown, gave assurances that the Coast Guard will not be deterred from conducting search and rescue efforts around offshore wind facilities, as some fishermen have feared.
“The Coast Guard’s response will be a great relief to Rhode Island’s commercial fishermen,” Sosnowski is quoted in a recent story in The Independent. “We have many concerns regarding navigational safety near wind farms, and that was the biggest.”
The anticipated release of the BOEM report coincides with President Trump’s efforts to weaken environmental impact reviews for all energy proposals, including wind, coal, and natural gas. National Environmental Policy Act (NEPA) reviews have slowed pipeline projects such as Keystone XL and, as of last summer, Vineyard Wind. Both industries praised the move to loosen environmental rules. Environmentalists, meanwhile, fear that the removal of terms such as “cumulative,” "direct," and "indirect" from NEPA’s directives will nullify future federal efforts to address the climate crisis.
Once the expanded environmental impact statement is released, BOEM will offer a comment period and hold public hearings
Stephens leaves Vineyard Wind
Barrington native and Providence resident Erich Stephens resigned at the end of 2019 from Vineyard Wind, a company he helped found in 2009 and is now co-owned by Avangrid and Copenhagen Infrastructure Partners. The original wind company was called Offshore MW. Prior to Vineyard Wind, Stephens was head of development for Bluewater Wind, one of the first U.S. offshore wind companies.
Stephens has considerable roots in Rhode Island. He attended Barrington High School and received his undergraduate degree from Brown University. He was founder and executive director of People’s Power & Light, now called the Green Energy Consumers Alliance. He was also a founding partner of Solar Wrights, a residential solar company that was based in Barrington and moved to Bristol. The company was later acquired by Alteris Renewables. Stephens also worked for two of Rhode Island’s first oyster farms.
More megawatts
New York plans to add 1,000 megawatts of offshore wind power to the 1,700 megawatts it awarded last summer to offshore wind projects that will deliver electricity to Long Island and New York City.
The state also announced it’s taking bids for $200 million in port development projects that will support the offshore wind industry.
The recent notifications are part of the state’s Green New Deal, which aims for 9 gigawatts of offshore wind by 2035 and 20 large solar arrays, battery-storage facilities, and onshore wind turbines in upstate New York. The state aims for 100 percent renewable energy by 2040.
The latest offshore wind projects consist of the 880-megawatt Sunrise Wind facility, developed by Ørsted and Eversource Energy, to power Manhattan. Long Island will receive up to 816 megawatts from the Empire Wind facility, developed by Equinor of Norway.
Pricing for the projects hasn’t been made public.
Offshore leader
Based in Denmark, Ørsted is the early leader in the size and number of U.S. offshore wind projects. Ørsted was awarded the 400-megawatt Revolution Wind project for Rhode Island. It’s also developing the 1,100-megawatt Ocean Wind facility in New Jersey, a demonstrations project in Virginia, and projects in Connecticut, Delaware, Massachusetts, and Maryland. The company acquired Providence-based Deepwater Wind in 2018 for $510 million.
Ocean Wind, New Jersey’s first offshore wind project, and the 120-megawatt Skipjack Wind Farm off Maryland will use General Electric’s huge 12-megawatt Haliade-X turbines. The 853-foot-high turbines are the tallest in production and have twice the capacity of the 6-megawatt GE turbines now spinning off Block Island, which are 600 feet tall.

The Northeast Canyons and Seamounts Marine National Monument, the only national monument in the Atlantic Ocean, remains controversial more than two years after it was designated by President Obama in September 2016.
Fishermen brought suit to overturn the designation — the suit was dismissed last October, but it’s being appealed — President Trump has threatened to use his executive authority to revoke the designation, despite uncertainties as to whether he can legally do so, and the Interior Department has recommended that the Trump administration reopen the monument to commercial fishing.
Peter Auster, however, argued in a lecture at Providence’s Roger Williams Park Zoo on Feb. 28 that the 4,900-square-mile area about 150 miles off Cape Cod is deserving of protection because of its high species diversity, wide variety of habitats, and its numerous creatures that are sensitive to disturbance.
A senior research scientist at Connecticut’s Mystic Aquarium, Auster was a key player in building the scientific case for why the area should be designated a national monument. He has led multiple research projects to explore the area using submersible vessels, remotely operated vehicles, and autonomous vehicles, all of which have revealed an unusual array of marine life, from “Dr. Seussian species” of fish to dozens of kinds of deep-sea corals.
“A dive into the canyons and seamounts demonstrates the magic of the ocean,” he said. “There’s a whole garden of organisms that live there.”
About the size of Connecticut, the monument includes two distinct areas, one that covers three canyons and one that covers four seamounts. (NOAA)
The monument includes a portion of the edge of the continental shelf, where the seafloor drops sharply from a depth of about 600 feet down to 3,000, and where four extinct underwater volcanoes jut upward from the seafloor. The monument got its name from those underwater volcanoes — called seamounts — and a number of canyons carved into the shelf edge by ancient rivers.
“Those canyons and seamounts create varied ecotones in the deep ocean with wide depth ranges, a range of sediment types, steep gradients, complex topography, and currents that produce upwelling, which creates unique feeding opportunities for animals feeding in the water column,” Auster said.
Using colorful photographs of rarely seen creatures to illustrate his presentation, Auster called the area a “biodiversity hot spot,” noting that at least 73 species of deep-sea corals live in the area, including 24 that were found there for the first time during a research expedition in 2013. Many of those corals serve as hosts to other creatures — crabs, shrimp, and starfish, for instance — that are only found on those particular corals.
New England Aquarium researchers have found that the monument’s surface waters serve as feeding grounds for an abundance of whales, sea turtles, sharks, and seabirds, as well as fish that migrate from the deep water to the surface every day to feed.
In addition, Maine Audubon recently discovered that the monument area is where many of the region’s Atlantic puffins spend the winter. And researchers from the Northeast Fisheries Science Center, in Woods Hole, Mass., found that significant numbers of the extremely rare True’s beaked whale, one of the deepest diving marine mammals in the world, spends the summer in monument waters.
Despite these recent discoveries, scientists say there is still a great deal to be learned about the area.
“We don’t yet know everything we need to know to manage the monument,” Auster said.
At least 73 species of deep-sea corals live in the area, including bamboo coral. (NOAA)
On his scientific to-do list is an assessment of the biological diversity of the area and how it’s distributed in the monument; an assessment of ecological change over time; a better understanding of species interactions; and an assessment of how the region has recovered from natural and human-caused disturbances.
While the status of the monument remains in limbo, a number of additional threats may be lurking. So far, commercial fishing has only impacted the shallow areas of the monument on the continental shelf, but Auster said there are increasing efforts to fish in the deeper waters. In addition, the Trump administration is advocating for expanded oil and gas exploration in the waters off the East Coast, and the growing seabed mining industry may see the seamounts as potentially valuable sites for methane hydrate mining or manganese crust mining.
While Auster seems somewhat confident that the monument designation will hold, and he’s already working on making the case for a second marine national monument in the Atlantic — this one at Cashes Ledge in the middle of the Gulf of Maine — he acknowledged that there are influential political forces at work that could derail the monument designation.
“Like every monument, there are people who suggest that it isn’t a good thing to conserve examples of our natural heritage for future generations,” Auster said. “The end of this story remains to be written.”

From Robert Whitcomb's "Digital Diary'' column in GoLocal24.com.
The Boston Globe ran a fascinating article on Jan. 9 (“The hardy kiwi: scourge or savior for farmers?’’) about afruit, called a “hardy kiwi,’’ related to the famous fuzzy kiwi you can find in supermarkets. The hardy kiwi has a smooth skin and is smaller than its fuzzy cousin. It’s also delicious and, reports The Globe, has “twice the vitamin C of an orange, twice the dietary fiber of an apple and as much potassium as a banana.’’
But of particular interest here is that is hardy enough to grow very well even in most of New England. It could become quite a cash crop.
The trouble is that some people, such as at the Audubon Society, see the plant, which is a fast-growing vine, as an invasive species that would strangle some woodlands as has kudzu, which has been moving north with global warming. So there’s a campaign underway to add hardy kiwi to the state’s prohibited plant list. Of course, you could say that all plant and animal species (especially people!) are originally invasive. Life spreads around, whether we like it or not
Trying to ban the plant would be a mistake. For one thing, there’s little evidence that that it would take over a lot of woodland. Foes point to hardy kiwi’s proliferation in a section of Lenox, Mass., but that’s because the plants there are basically remnants of those used ornamentally at the big Gilded Age estates in the Berkshires a century ago after they were brought in from Japan. There’s no indication that they’ve been spreading willy-nilly across New England inthe past century!
Finally, the hardy kiwi offers the opportunity for New England to have another – and very healthy – product, like cranberries and blueberries. Now, another invasive species – bittersweet – is quite another thing. It spreads very fast and doesn’t produce anything you can eat.

And New England’s hardy kiwi may not have to be so hardy in coming years. Climate scientists at the University of Massachusetts at Amherst’s Northeast Climate Science Center predict that New England’s temperatures will rise by an average of 3.6 degrees Fahrenheit above pre-industrial levels by 2025 – a faster rise than in most places. Scientists cite New England’s position in the prevailing westerly winds, the region’s latitude and dramatically warming temperatures in the Gulf of Maine as among the reasons.
This is another wake-up call to reduce carbon emissions and to prepare coastal regions for higher sea levels and thus disastrous flooding. One good step would be ending at least the current version of the National Flood Insurance Program (NFIP), which subsidizes irresponsible building, mostly by affluent people, on beaches (and some flood-prone inland places).
Lloyd’s, the giant London-based insurance market, has called on the federal government to stop providing these subsidies to homeowners and businesses to build in coastal areas exposed to risks related to climate change.
And Lloyd’s says that NFIP subsidy regime is financially unsustainable. The program is now in the red by more than $24 billion, largely because of such coastal flood disasters as Hurricane Katrina, in 2005, and Superstorm Sandy, in 2012. It will probably get worse.
People who are environmental-science “skeptics,’’ such as our next president, and/or who basically want industry to do whatever it wants to maximize profits, might look at the Gulf of Maine, where anti-pollution regulations imposed on coal-fired power plants in the Midwest cut mercury levels in Gulf of Maine by 2 percent a year in the 2004-2012 period, Maine Public Radio reported. Bad for utility execs and shareholders, good for public health and fishermen. Enjoy your sushi.

The New England Fishery Management Council recently dealt a serious blow to the region’s ocean health with a vote to sharply reduce the amount of seafloor set aside to protect marine habitat for fish.
If approved, the measure would remove protections for more than 5,400 square miles — an area the size of Connecticut — and open the habitat to damaging forms of bottom-trawl fishing and scallop dredging. The final decision rests with the National Marine Fisheries Service of the National Oceanic and Atmospheric Administration (NOAA Fisheries), whose officials should reject this risky action.
Over a decade in the making, the council’s Omnibus Habitat Amendment was meant to identify and protect essential fish habitat for all species managed by the council, in accordance with the law. Like all animals, fish need places where they can find food and shelter and reproduce. As I like to say, habitat is where fish make more fish, and New England needs more fish.
The region’s cod population has crashed to a historic low because of decades of overfishing and, more recently, the effects of warming waters stemming from a changing climate. New England is home to more overfished species than any other fishing region in the nation, largely as a result of risky management decisions that have undermined sustainability. The situation became so dire that New England’s fishery for cod and other bottom-dwelling fish was declared a federal disaster in 2012, and taxpayers have funded hundreds of millions of dollars in relief aid for fishermen.
Last December, some 140 noted marine scientists wrote to the council urging more habitat protection, to help recover depleted populations and make those fish more resilient to the stress brought by climate change. When the council’s omnibus amendment was open for public comment, more than 150,000 people spoke up for habitat protection. Unfortunately, the council rejected both scientific advice and public opinion in favor of short- term economic gains for the fishing and seafood-processing industries.
The numbers are striking. The council has voted to slash currently protected areas by about 60 percent throughout the region. East of Cape Cod on Georges Bank, the historically rich fishing grounds where cod and other fish are known to spawn and seek shelter, 81 percent of the areas closed to damaging fishing gear would be reopened.
Some of these closed areas have been in place for more than 20 years, and a large body of science documents their value as fish habitat. Closed areas in the Gulf of Maine are known to shelter some of the last remaining old female cod, which are crucial to the reproductive capacity of the population and the species’ ability to rebound in numbers. But the council’s vote would cut protections in the Gulf of Maine by nearly 15 percent.
The council’s habitat amendment also fails to adequately address the spawning areas where fish aggregate seasonally. The council ignored many of the spawning “hot spots” scientists had mapped out for a variety of species. Even the small closures the council left in place still allow many kinds of destructive fishing, including clam dredges, gill nets and giant mid-water trawl vessels. In addition to killing fish, these types of gear disrupt spawning behavior, dispersing aggregations of fish.
Further, the council did little to ensure an adequate supply of the prey animals that fish need for food. For example, it entirely ignored Atlantic herring in the decisions on spawning and habitat protection. These forage fish, which play a vital role in the ecosystem, are another essential element of healthy habitat as defined by both scientists and the law.
The Northeast regional administrator for NOAA Fisheries, John Bullard, took note of these many inadequacies as the habitat plan was nearing completion. In a sharply worded letter in April, Bullard warned that the council had “not made use of the best available scientific information” and might “reverse 20 years of habitat protection and recovery.” He concluded that the habitat amendment would probably not meet legal requirements without some major improvements.
The council didn’t heed his warning. As the members prepared for the final roll call vote on June 16, the person who had worked most closely on the habitat amendment throughout its long development, Rhode Island council member Dave Preble, offered a telling comment.
“This council has purposely ignored the science and produced an amendment that is indefensible,” he said. “If you want to have big fish, you have to feed and protect the small fish.”
The amendment will now go to NOAA Fisheries for consideration. I hope that the agency will reject it and send it back to the council demanding a habitat plan guided by science and the public interest. New England’s fish and fishing communities deserve better than what the council is offering.

From ecoRI News Cashes Ledge, 80 miles off the coast of Gloucester, Mass., is an oasis for sea life. The peaks and canyons of the 22-mile-long underwater mountain range create nutrient- and oxygen-rich currents that support diverse habitats throughout the 550-square-mile area.
At elevations where sunlight reaches the submerged peaks grows the largest continuous kelp forest — one of the most productive ocean ecosystem types — along the Atlantic Seaboard. Cashes Ledge is home to the depleted Atlantic wolffish, red cod, sea stars, anemones and rare sponges, and acts as a migratory pass for blue sharks, humpback and right whales, and bluefin tuna.
As a pristine example of a Gulf of Maine ecosystem, Cashes Ledge has been used by scientists as an open-sea research laboratory for decades. Relatively unimpaired by human activity or pollution, the area acts as a benchmark against which the health of the rest of the ocean is measured.
Since 2002, Cashes Ledge has been protected by the New England Fishery Management Council (NEFMC) from habitat-damaging fishing practices, such as bottom trawling and scallop dredging, in an effort to restore depleted fish stocks, including cod. Cod stocks are at historic lows — 3 percent of a sustainable level in the Gulf of Maine — because of decades of overfishing and high-risk fishery-management decisions, according to environmental groups such as the Conservation Law Foundation (CLF).
Bottom trawling at Cashes Ledge could also destroy entire sections of kelp forest and wipe out populations of sea anemones that would take more than 200 years to recover, according to the CLF.
Protected areas, such as the one surrounding Cashes Ledge, also have been shown to be more resilient to climate change, and provide sea life places to adapt to warming and acidifying waters.
The Magnuson-Stevens Act of 1996 required the NEFMC to identify essential fish habitat, minimize adverse effects caused by fishing as much as feasible considering economic and other factors, and find ways to enhance essential fish habitat. The act also requires that the council update and improve habitat programs every five years. The NEFMC’s habitat management plan was due for a five-year review in 2004, but is still incomplete. The plan, titled the “Omnibus Essential Fish Habitat Amendment 2,” is currently in draft form and is open for public comment until Jan. 8.
The current draft offers a range of possible conservation alternatives, each made up of one or more possible protected areas in a geographic region encompassing the Gulf of Maine, Georges Bank and southern New England. Each possible protected area was determined using multiple analyses, including the Swept Area Seabed Impact model, and other information such as analysis of juvenile groundfish distributions, combined with information about the current status of various stocks and their affinities for vulnerable habitat types.
After the public comment period closes, the NEFMC will consider each comment and then choose the alternatives that it believes will best protect essential fish habitat from the negative effects of fishing to the extent feasible considering economic and other factors.
The CLF, an organization that advocates for increased protection of ocean habitat in New England, claims that many of the alternatives in the draft Omnibus Habitat Amendment would reverse protections previously granted to vital areas in New England waters in favor of shortsighted fishing-industry interests. The groundfish and scallop industry, for example, is pushing to reduce the area currently protected around Cashes Ledge by 70 percent.
According to a September brief by the Pew Charitable Trusts titled “Risky Business: How denial and delay brought disaster to New England’s historic fishing grounds,” Georges Bank could lose 96 percent of its remaining protected area, despite cod populations being at only 8 percent of a sustainable level. The brief states, “Overall, if the NEFMC chose the smallest closed-area option for each subregion, the total area afforded year-round protection would drop by 71 percent to just 1,909 square nautical miles” — a reduction roughly the size of Connecticut.
According to Shelley, protected areas like Cashes Ledge are essential to the long-term health of New England’s fisheries. Older and larger fish are vital to the recovery of depleted populations, he said, because they experience greater reproductive success than their younger counterparts. Protected areas have been shown to contain more numerous and older fish than unprotected areas and become incubators for neighboring waters.
Shelley said California has experimented with habitat closures as a way of increasing fish stocks. He said fisherman initially opposed the closures, but many came around after experiencing an increase in catch along the edges of the protected areas.
In another example, cited in the Pew brief, “the biomass of scallops across the New England fishery region increased dramatically in association with the closures on Georges Bank. New Bedford, Massachusetts, has the highest fishing revenue in the nation because of scallops.”
Many New England fisherman want to reopen protected areas such as Cashes Ledge to fishing because there are more fish in them, but according to Shelley more abundant fish populations in closed areas prove the protections are working and should remain in place or be expanded. If the protected areas are reopened, he said, fisheries will revert back to depleted states.
More of New England’s waters need to be protected, not less, according to Shelley. He said the Omnibus Habitat Amendment isn’t going to provide that result.
“In this case, preserving the status quo is better than the preferred alternatives of the NEFMC,” Shelley said.
In early December, 138 marine scientists and academics signed a letter to National Oceanic and Atmospheric Administration (NOAA) fisheries officials expressing deep concern about any proposals from the NEFMC that would significantly reduce habitat protection. Signers include leading names in marine and fisheries biology such as Daniel Pauly, Callum Roberts and Sylvia Earle.
“In terms of area alone,” they wrote, “the Amendment offers no alternatives that would (expand) the overall area protected in the region. Given the current state of some of the managed fish populations, protecting more, not less, habitat would seem to be an alternative worthy of consideration.”
The letter suggests enacting more comprehensive fishing-gear restrictions in protected areas, instead of only prohibiting bottom-tending gear. It also contests the arguments in support of diminishing habitat protection.
“Under certain scenarios,” the signers wrote, “a smaller amount of diverse habitat may have greater ecological benefit than a larger amount of lower value (habitat). But we are not persuaded that there is sufficient evidence that this scenario can be applied here with a high degree of safety or certainty. The (amendment) does not make a strong case that the new network of (protected habitat) will be a net gain or even maintain the ecological status quo for the region as a whole.”
The letter concludes that reductions in habitat protection would be highly unwise and unsupportable by current science.
“Too often, NEFMC has ignored or downplayed scientific data in favor of the short-term economic interests of the fishing industry,” Peter Baker, director of Northeast U.S. ocean issues for The Pew Charitable Trusts, wrote in a recent blog post. “That’s the sort of decision-making that brought the region to its current state: a federally declared fishery disaster that has required tens of millions of taxpayer dollars in assistance. It’s time to start listening to the science.”
More of the waters and seafloor identified as important by scientists that cod need to spawn, feed and mature should be made off-limits, according to Baker.
“Habitat is where fish make more fish. And what New England needs now is more fish,” he wrote. “Unfortunately, New England’s regional fishery managers have proposed a plan that could actually result in the opposite, a dramatic reduction of habitat areas.”
To help the public focus their comments on the alternatives likely to be chosen, the NEFMC released its own preferred alternatives prior to the comment period. In most cases, the preferred alternatives are not the “worst-case-scenarios” many conservation groups cite to bolster their arguments.
The NEFMC has suggested maintaining one existing large closed areas in the western Gulf of Maine, and the eastern Gulf of Maine, currently unprotected, would stand to gain protections from the amendment. However, in most cases, the council’s preferred alternatives reduce the overall area currently protected.
Current closed areas on the left are generally larger than those preferred by the NEFMC on the right. The NEFMC didn’t selecte any preferred habitat alternatives in the Georges Bank or Great South Channel/Southern New England subregions, but its analysis does include these subregions and offers a variety of alternatives. (Omnibus Essental Fish Habitat Amendment 2 Public Hearing Documment)At a public hearing for the draft Omnibus Habitat Amendment in Warren, R.I., in early December, clam, lobster and scallop fishermen spoke out in favor of specific alternatives that would open areas currently closed to fishing, prevent areas currently open to fishing from becoming closed, and relaxed fishing-gear regulations to improve their catch.
One surf-clam fisherman said he had been operating in the same fishing grounds on the Nantucket Shoals for 35 years without negative impacts. He requested the Omnibus Habitat Amendment include an exemption for surf-clam fishing, including in closed areas, because of the relatively benign gear used by his fishery.
Jerry Elmer, of CLF Rhode Island, was the sole conservationist to testify at the hearing. “This fish habitat amendment should be viewed as an opportunity to enlarge protected habitat,” he said.
Jeremy Collie, professor of oceanography at the University of Rhode Island, testified in favor of alternatives that would continue year-round closures of the most vulnerable habitat on northern Georges Bank. He said it would be a mistake to allow bottom fishing in these areas.
In a follow up e-mail to ecoRI News, Collie wrote that he generally agrees with the options favored by the NEFMC and that he supports the council’s analysis showing that the favored alternatives will result in mostly neutral or positive economic and habitat impacts.
