Brad Warren & Julia Sanders: Washington’s Initiative 1631 will help fight ocean acidification

November 2, 2018 — We write today to announce our support for Washington’s Initiative 1631. As businesses who rely on healthy fisheries for a significant portion of our income, we believe this is a well-designed policy that offers us – and our customers – the best possible chance against an uncertain future fraught with the threats of changing ocean conditions.

It’s become clear that our fisheries need a lifeline. Here in Washington, we are experiencing the worst ocean acidification anywhere in the world. Research has firmly established the cause of this problem: emissions from burning coal, oil and gas mix into the ocean, altering its chemistry. The consequences loomed into headlines a decade ago when the oyster industry lost millions and nearly went out of business during the oyster seed crisis. Temporary and limited adaptation measures in hatcheries are keeping them in business, but in the rest of the oceans, fisheries that put dinner on billions of tables are at risk. Here in the Northwest, harvests are already being eroded and even shut down by the effects of unchecked carbon emissions.

The “warm blob,” an unprecedented marine heatwave off the West Coast, reached its height in 2015 and caused mass fatalities. In the Columbia River, a quarter-million salmon died. The largest recorded toxic algae bloom shut down the Dungeness crab fishery for months. The food web crashed, and marine creatures were spotted farther north than ever before. Sea surface temperatures never returned to their previous norm, and new research indicates another blob is forming.

Summers have become synonymous with a smoky haze from wildfires causing poor visibility and poor health – this summer the National Weather Service warned even healthy adults in some Washington areas to stay indoors due to hazardous air quality. At the same time, our iconic orca whales are starving from a lack of Chinook salmon. The Chinook in turn are suffering from a lack of the zooplankton that juveniles eat.

Research has made it clear that some of our most lucrative fisheries are vulnerable to ocean acidification: king crab, Dungeness crab, and salmon. Scientists also warm that combining stressors – like warming with ocean acidification – makes survival in the ocean all the more precarious.

Startling new research finds large buildup of heat in the oceans, suggesting a faster rate of global warming

November 1, 2018 — The world’s oceans have been soaking up far more excess heat in recent decades than scientists realized, suggesting that Earth could be set to warm even faster than predicted in the years ahead, according to new research published Wednesday.

Over the past quarter-century, Earth’s oceans have retained 60 percent more heat each year than scientists previously had thought, said Laure Resplandy, a geoscientist at Princeton University who led the startling study published Wednesday in the journal Nature. The difference represents an enormous amount of additional energy, originating from the sun and trapped by Earth’s atmosphere — the yearly amount representing more than eight times the world’s annual energy consumption.

In the scientific realm, the new findings help resolve long-running doubts about the rate of the warming of the oceans before 2007, when reliable measurements from devices called “Argo floats” were put to use worldwide. Before that, differing types of temperature records — and an overall lack of them — contributed to murkiness about how quickly the oceans were heating up.

The higher-than-expected amount of heat in the oceans means more heat is being retained within Earth’s climate system each year, rather than escaping into space. In essence, more heat in the oceans signals that global warming is more advanced than scientists thought.

Ocean Shock: Lobster’s Great Migration Sets Up Boom and Bust

October 31, 2018 — STONINGTON, Maine — This is part of “Ocean Shock,” a Reuters series exploring climate change’s impact on sea creatures and the people who depend on them.

A lobster tattoo covers Drew Eaton’s left forearm, its pincers snapping at dock lines connecting it to the American flag on his upper arm. The tattoo is about three-quarters done, but the 27-year-old is too busy with his new boat to finish it.

Eaton knows what people here in Stonington have been saying about how much the boat cost him.

“I’ve heard rumors all over town. Small town, everyone talks,” he says. “I’ve heard a million, two million.”

By the time he was in the third grade, Eaton was already lobstering here on Deer Isle in Downeast Maine. By the time he was in the eighth grade, he’d bought his first boat, a 20-footer, from a family friend. The latest one, a 46-footer built over the winter at a nearby boatyard, is his fourth.

Standing on the seawall after hauling lobster traps for about 12 hours on a foggy day this August, he says he’s making plenty of money to cover the boat loan. He’s unloaded 17 crates, each carrying 90 pounds of lobster, for a total haul of nearly $5,500. It’s a pretty typical day for him.

Eaton belongs to a new generation of Maine lobstermen that’s riding high, for now, on a sweet spot of climate change. Two generations ago, the entire New England coast had a thriving lobster industry. Today, lobster catches have collapsed in southern New England, and the only state with a significant harvest is north in Maine, where the seafood practically synonymous with the state has exploded.

The thriving crustaceans have created a kind of nautical gold rush, with some young lobstermen making well into six figures a year. But it’s a boom with a bust already written in its wake, and the lobstermen of the younger generation may well pay the highest price. Not only have they heavily mortgaged themselves with pricey custom boats in the rush for quick profits, they’ll also bear the brunt of climate change — not to mention the possible collapse of the lobstering industry in Maine as the creatures flourish ever northward.

Shifts by 85 percent of species

In the U.S. North Atlantic, fisheries data show that at least 85 percent of the nearly 70 federally tracked species have shifted north or deeper, or both, in recent years when compared with the norm over the past half-century. And the most dramatic of species shifts have occurred in the last 10 or 15 years.

Just in the last decade, for example, black sea bass have migrated up the East Coast into southern New England and are caught in the same traps that once caught lobsters. Back in the 1980s and 1990s, only 50 percent of lobster caught in the United States came from Maine. That started to shift in the 2000s, and this decade, nearly 85 percent of all lobster landings are in Maine.

Some North Carolina seafood unsafe to eat after Hurricane Florence

October 26, 2018 — Some seafood caught in North Carolina may not be safe to eat in the aftermath of Hurricane Florence.

Florence made landfall in Wrightsville Beach on Sept. 14. It was a Category 1 storm at landfall, and the storm moved extremely slowly–dumping dozens of inches of rain on many parts of North Carolina.

Florence dumped 8 trillion gallons of water on North Carolina. That’s enough to fill Falls Lake more than 70 times.

The influx of water turned creeks and streams into whitewater rapids that picked up everything in their paths.

The polluted runoff spilled into the Cape Fear River and Neuse River, then into the Pamlico Sound, and finally into the Atlantic Ocean.

The runoff forced North Carolina’s Department of Marine Fisheries to order a blanket ban on harvesting any shellfish off the coast. Months after the storm, miles of coastline remain off limits.

Wildlife most vulnerable to the pollution are filter feeders like clams, mussels and oysters.

Culinary community joining forces to help their fishermen friends affected by hurricanes

October 25, 2018 — In the wake of Hurricane Florence, North Carolina’s culinary and hospitality community has raised hundreds of thousands of relief dollars through a series of meals and events.

The latest aims to help North Carolina’s fishermen and shellfish growers impacted by the storm.

This Saturday, “Gone Fishing” will feature more than a dozen North Carolina chefs — including several James Beard nominees and winners — from Wilmington to Pittsboro at the new Junction West in Raleigh’s Warehouse District.

The event is organized by chefs Ashley Christensen of Poole’s, Jake Wood of 18 Seaboard and Locals Seafood, with proceeds going to the state’s fishermen and oyster and clam farmers affected by Hurricane Florence. The Core Sound Waterfowl Museum and Heritage Center is helping distribute the funds and will accept separate donations for North Carolina watermen.

Many of the participating chefs and restaurants focus on North Carolina seafood, including 18 Seaboard, Postmaster and The Cortez.

MSC science director: Greater resolution needed in global fishing impact studies

October 25, 2018 — Michel Kaiser, the recently-appointed science and standards director at the Marine Stewardship Council (MSC), has stressed the need for higher resolution data when estimating the global fishing footprint, in an opinion piece on the Conversation.

The discussion comes after the publication of a report in February which estimated that 55% of the planet’s oceans had been affected by fishing activities. However, Kaiser said this study, which was created from analysis of squares roughly 3000 square kilometers in area, produces a figure that is off by a factor of ten when compared to a more recent August study produced using higher resolution data (1-3 sq. km).

The MSC science director also noted a study published in October 2018 looking into the global footprint of bottom trawling. The paper looked at 24 regions of the global continental shelf, each analyzed using squares of less than 9 sq. km. The team, from the State University of New Jersey, discovered that 24% of the measured areas had been affected by bottom trawling, one of the most destructive fishing practices.

Hurricane Michael leaves long-term rebuild for Florida

October 23, 2018 — Hurricane Michael blew through the Florida panhandle nearly two weeks ago, but it appears the major storm will have long-lasting effects on the state’s commercial fishing industry.

The state’s shellfish industries were especially hard-hit, as the storm impacted areas known for clam and oyster beds.

T.J. Ward, whose family has worked in the shellfish business for five generations, said his aquaculture business “is done for at least a year or two” in an interview with WBUR radio in Boston.

“The damage in Apalachicola is the worst I’ve ever seen, and locals that are older than me and been through more hurricanes haven’t seen it this bad,” he said.

The impact to fisheries isn’t just to human structures, as the environment can be heavily impacted by flood waters changing the shape of the landscape.

“We won’t know how this system responds until after. When you look at catastrophic storms, very often they can shift baselines in systems,” Duane DeFreese, executive director of the Indian River Lagoon National Estuary Program, told Florida Today. “Completely over-wash the wetland, upland transitions, and then it takes some time for systems to recover. The commercial fishing impacts on this could be extreme.”

The effects also will be felt beyond the Gulf for at least one company.

According to The Seattle Times, Michael took a nearly-completed 261-foot trawler and ripped it from the shipyard’s mooring in Panama City, Florida. The ship, being built at Eastern Shipbuilding for Glacier Fish Co., was supposed to depart for Alaska in November and start processing groundfish.

Hurricane Michael leaves a seaside Florida town in an existential crisis

October 23, 2018 — For generations, families have come to Mexico Beach to soak up old-style Florida: the mom-and-pop seafood shacks, the dinky one-story motels and pastel bungalows, the retro ice cream parlor with claw machines and vintage arcade games.

But Hurricane Michael, which less than two weeks ago pummeled the tiny seaside town with 155-mph winds and demolished roughly three out of every four buildings, has left the community in an existential crisis. Nobody is sure what comes next.

Many residents and business owners, anticipating massive insurance shortfalls, have yet to decide whether to commit to the daunting challenge of rebuilding structures strong enough to withstand the next big storm.

About a third of the town’s 1,200 full-time residents are senior citizens. Many homes were not covered by flood insurance. A vast swath of older ranch-style homes and commercial structures sat at ground level and did not meet the state’s current elevation and windstorm requirements.

“They’re gonna make you build so heavy duty, you can’t afford to rebuild,” said Charles “Chuck” Smith, 56, owner of the Gulf View Motel, a modest 1940s-era building that his parents bought in the mid-1980s.

What happens to fish and other sea creatures underwater during a hurricane

October 18, 2018 — Hurricanes can be just as deadly for marine life, sometimes stranding them on land or far out at sea. But sometimes marine life benefits or even thrives after these extreme weather events.

Normally when a hurricane is headed for us, we run the other way. But not Isla. She’s a leatherback turtle who was meandering off the coast of Virginia when she accidentally swam straight into Hurricane Florence. Scientists were worried she’d get caught up in the worst of the storm but Isla managed to survive by swimming toward deeper waters.

Turns out, there’s a part of hurricanes we don’t often think about: What happens under the surface. And Isla is just one example.

Far out at sea, fish that live near the surface might feel some turbulence as a storm passes. But most sea creatures — including dolphins, whales, and sharks — avoid the rough surface water and swim to calmer seas. But it’s a different story near shore.

Changes in water temperature and salinity can be catastrophic for marine life. Hurricanes can generate massive waves. Which mix warm surface water with colder, saltier water below generating currents that extend up to 91 meters below the surface. These currents are so strong that they can sweep manatees inland to canals and ponds or away from the coastal waters they prefer, and out into the open ocean. Where they can become disorientated, and even die.

Hurricanes also bring heavy rain, so freshwater often floods coastal regions. And because freshwater is less dense than salt water, it sits on top of the sea water like oil on vinegar. Where it can prevent oxygen from reaching the salty layer below. And disrupt the salinity levels, which can lead to sores, lesions, and ultimately death in whales, dolphins, and porpoises.

Hurricanes also kick up dirt and sand in shallow seas. Which can kill fish by clogging their gills. Experts think this is probably one of the factors that killed an estimated 9.4 million saltwater fish in 1992, during Hurricane Andrew. The dirty, murky water also blocks sunlight from reaching corals and seagrass. In fact, scientists found that coral cover in the Caribbean decreases by 17% in just one year after a hurricane strikes. And that’s in addition to the stress coral already face from human interference.

But it’s not always so bad for sea life. After Hurricane Katrina damaged or destroyed almost 90% of fishing boats in the Mississippi Sound scientists observed a huge increase in dolphin births. Without the fishing boats, dolphins suddenly found themselves with more available prey which helped their populations thrive.

Scallop fishery may be imperiled by acidic seas

October 16, 2018 — Increasingly acidic seas pose a serious threat to the sea scallop fishery, a recent collaborative study by the University of Virginia, the Ocean Conservancy, the NOAA Northeast Fisheries Science Center, and the Woods Hole Oceanographic Institution (WHOI) concluded.

“As levels of carbon dioxide increase in Earth’s atmosphere, the oceans become increasingly acidic — a condition that could reduce the sea scallop population by more than 50 percent in the next 100 years under a worst-case scenario,” the study states. Models from the study, which were published recently in the journal PLOS One, combine existing data with several factors that impact the fishery: “future climate change scenarios, ocean acidification impacts, fisheries management policies, and fuel costs for fishermen.” Those factors were modeled out into 256 different possibilities.

Oceans absorb vast quantities of carbon dioxide. Fossil fuel emissions exacerbate what the oceans take in, further acidifying the water. “That acidity can corrode the calcium carbonate shells that are made by shellfish like clams, oysters, and scallops, and even prevent their larvae from forming shells in the first place,” the study states.

“[The scallop fishery is] healthy and valuable today in part because it is very well managed,” says Scott Doney, a co-author from WHOI and the University of Virginia. “We also used the model to ask whether management approaches could offset the negative impacts of ocean acidification.”

It couldn’t. In every scenario, elevated carbon dioxide levels created acidiferous ocean water. The culprit, the study concluded, was “unabated carbon emissions.”
