Broken Blades, Angry Fishermen and Rising Costs Slow Offshore Wind

September 12, 2024 — The collapse of a giant wind turbine blade off the Massachusetts coast confirmed Peter Kaizer’s worst fears about the dangers a new clean energy business could pose to fishermen like him.

Jagged pieces of fiberglass and other materials from the shattered blade drifted with the tide, forcing officials to close beaches on Nantucket and leaving Mr. Kaizer worried about the threat the fragments might pose to his vessel and other fishing boats, especially at night when the debris would be harder to avoid.

“All these small boats could be subject to damage,” Mr. Kaizer said. “Everyone wants this green legacy, but at the cost of what?”

The blade, which was more than 300 feet long, failed in July, but the repercussions are still unfolding at the $4 billion project that it came from — Vineyard Wind 1. Developers had hoped to finish the project this summer, making it the first large-scale wind farm completed in U.S. waters, but now that goal will take a lot longer than expected.

The blade failure is the latest problem slowing the fledgling U.S. offshore wind industry, which the Biden administration and East Coast states are counting on to deliver emission-free energy to millions of people from Virginia to Maine. President Biden and governors of those states had hoped to follow the examples of European countries like Britain and Denmark, which have plunked down thousands of wind turbines around the North Sea.

But the American offshore wind business has struggled to get going because of cost overruns, delays in issuing permits, and opposition from local residents and fishing groups. Several large projects were canceled or postponed even before the blade failure in Massachusetts because their costs increased sharply and developers did not anticipate supply chain problems and higher interest rates.

American lobster show resilience amid climate change

September 12, 2024 — Experiments conducted at the Virginia Institute of Marine Science (VIMS) have shown that female American lobsters groom their offspring, and the grooming behaviors appear to remain stable despite the temperature and acidity conditions projected for Maine’s coastal waters by the end of the century. A study by researchers at William & Mary’s Batten School of Coastal & Marine Sciences shows that the species may be more resilient to the effects of climate change than previously thought.

The study examines how a changing climate may impact the reproductive success of species that brood or incubate and hatch their eggs. The findings were published in the journal Marine Ecology Progress Series and suggested that American lobsters can handle future ocean changes well, as their egg care and survival rates stayed stable under different conditions through the study’s tests.

Digging into the study

The study’s researchers partnered with the Maine Department of Marine Resources to obtain 24 lobsters from commercial operations for the study for five months. They secured female lobsters at market size with all legs intact, which are commonly lost in the wild.

NOAA fishery councils prepare to adapt to climate change

September 10, 2024 — Shifts in marine species migration and population concentrations are forcing NOAA Fisheries to rethink its regional administrative maps to reflect the new realities of changing ocean habitats.

In guidance released Tuesday, the agency’s Office of Sustainable Fisheries established a framework for when and how regulation of a species should be handed off from one regional fishery management council to another based on shifting species population dynamics. The guidance does not specifically mention climate change, but the effects of warming water on fish migration have been widely acknowledged by NOAA Fisheries, also called the National Marine Fisheries Service, and other experts.

“In anticipation of an increasing number of fish stocks shifting in geographic distribution, new fisheries emerging, and other demographic shifts in fisheries, the National Marine Fisheries Service has identified a need for guidance on determining the geographic scope of fisheries and on how to determine which regional fishery management councils will be responsible for preparing and amending new [and] existing fishery management plans for fisheries that extend or have moved beyond the geographical area of authority of any one council,” the agency said in the guidance document.

Biden-Harris Administration invests more than $23 million to remove marine debris

September 6, 2024 —  Today, the Department of Commerce and NOAA recommended more than $23 million in funding to support marine debris removal and interception efforts for 13 multi-year projects across 10 coastal U.S. states, three territories and the District of Columbia. This funding is provided by NOAA’s Climate-Ready Coasts initiative under the Biden-Harris Administration’s Bipartisan Infrastructure Law as part of President Biden’s Investing in America agenda.

The Climate-Ready Coasts initiative is focused on creating climate solutions by storing carbon; building resilience to coastal hazards such as extreme weather events, pollution and marine debris; restoring coastal habitats; building the capacity of coastal  communities; and supporting community-driven restoration.

“The Biden-Harris Administration is funding critical projects like these that will help remove and address harmful marine debris that can significantly impact water quality, habitats and economic prosperity in coastal communities across the nation,” said U.S. Secretary of Commerce Gina Raimondo. “These investments, made possible thanks to President Biden’s historic Bipartisan Infrastructure Law, will help improve coastal communities for decades to come by making sure they have the necessary resources to protect their ecosystems and local economies from the impacts of marine debris, which are exacerbated by climate change.”

Gulf of Maine’s rising temperatures bring challenges and opportunities to local fisheries

August 29, 2024 — The Gulf of Maine’s warming waters are profoundly affecting Maine’s working waterfront in more ways than one. Over the past decade, sea surface temperatures have surged, with recent years experiencing record-breaking warmth. This trend, largely attributed to climate change, poses significant challenges to local fisheries, but it also opens doors to new opportunities.

Over the last 10 years, there has been an unprecedented increase in the sea surface temperatures throughout the Gulf of Maine—something many scientists blame on manmade climate change. Out of the last six years, four of our summers have endured the warmest waters for Maine’s Gulf, with 2021 breaking a new record.

UN chief issues ‘SOS’ for Pacific Islands worst hit by warming ocean

August 27, 2024 — United Nations Secretary-General Antonio Guterres said on Tuesday ocean temperatures are rising in the Pacific Islands at three times the rate worldwide, and its population was “uniquely exposed” to the impact of rising sea levels.

Speaking to reporters in Tonga where the Pacific Islands Forum is being held, Guterres highlighted the findings of a report that showed the South West Pacific was worst hit by sea level rises, in some places by more than double the global average in the past 30 years.

“I am in Tonga to issue a global SOS – Save Our Seas – on rising sea levels,” he said.

“Rising seas are amplifying the frequency and severity of storm surges and coastal flooding. These floods swamp coastal communities. Ruin fisheries. Damage crops. Contaminate fresh water. All this puts Pacific Island nations in grave danger,” he said.

Counting All the Fish in the Sea May Be Even Trickier Than Scientists Thought

August 23, 2024 — Counting the number of fish in the ocean may well be one of science’s toughest jobs. It also produces a crucial tool governments use to protect marine ecosystems that feed millions of people across the world.

Fish stock assessments work a lot like climate models. Scientists gather a wide range of data from fish catches, like age and weight, and track environmental conditions, like the temperature of the sea, and use mathematical models to estimate the health of fish populations. The analysis is then used to make recommendations to governments.

[…]

“A lot of the things they say you need to do are already in place,” said Ray Hilborn, a professor of fishery science at the University of Washington. Many fishery managers, he explained, already look back at historical trends to correct for a possible tendency to over or undercount fish populations.

Steven Cadrin, a marine scientist at the University of Massachusetts Dartmouth, who has worked on fish stock assessments for decades, said the study’s findings are “invalid,” partly because the researchers used the most recent stock assessments as a benchmark for accuracy. More recent tallies of fish populations may be just as prone to error, he said.

The fisheries included in the study have some limitations. The study’s researchers examined fish assessments with ample data, which are largely done by some of the wealthiest countries in the world, such as the United States, Canada and Australia.

Still, some of the most troubled fisheries, in countries like India and Indonesia, don’t do thorough fish stock assessments, Dr. Hilborn said.

“The global fisheries problem,” he said, “is that about half of the world’s fish stocks are simply not assessed.”

US fishermen concerned ocean alkalinity experiments could impact their livelihood

August 23, 2024 — Waters in the New England region of the U.S. may soon be the location for a first-of-its-kind field trial to test a technique called ocean alkalinity enhancement (OAE), that researchers say could someday become a pivotal tool in the fight against climate change.

But, fishermen are concerned the experiment could further disrupt an ecosystem already contending with the effects of offshore wind energy development and climate change.

Scientists have more evidence to explain why billions of crabs vanished around Alaska

August 21, 2024 — Fishermen and scientists were alarmed when billions of crabs vanished from the Bering Sea near Alaska in 2022. It wasn’t overfishing, scientists explained — it was likely the shockingly warm water that sent the crabs’ metabolism into overdrive and starved them to death.

But their horrific demise appears to be just one impact of the massive transition unfolding in the region, scientists reported in a new study released Wednesday: Parts of the Bering Sea are literally becoming less Arctic.

Cape Cod scientists delay controversial climate change project after feds raise concern

August 19, 2024 — Cape Cod scientists are delaying a geoengineering project that looks to dump more than 60,000 gallons of sodium hydroxide into the ocean and has caught federal concerns around potential impacts on the ecosystem.

Scientists at Woods Hole Oceanographic Institution in Falmouth have pushed back the project from mid-September to next summer because they say a fully-equipped research vessel is no longer available.

Woods Hole’s decision to delay became public two days after the National Marine Fisheries published a warning last Monday that the project could “adversely affect federally-managed species and other NOAA trust resources.”

The experiment, consisting of two phases, would dump sodium hydroxide and freshwater into the Atlantic, temporarily changing the water’s chemistry – increasing carbon dioxide levels that the ocean absorbs.

Scientists say it’s an effort that could be a way to slow climate change in the long run.

The first phase of the so-called LOC-NESS project, short for “Locking away Ocean Carbon in the Northeast Shelf and Slope,” would release 6,600 gallons of sodium hydroxide solution roughly 10 miles south of Normans Land, an island off of Martha’s Vineyard.

The release of the solution would occur over two to three hours to “create a patch of alkalinity on the ocean surface and then monitored for up to 5 days by an on-site scientific research team,” according to project documents.

In the second phase, pushed back to 2026, scientists would dump up to 66,000 gallons into the Wilkinson Basin, nearly 40 miles northeast of Provincetown.
