Ocean acidification poses threat to lobsters

December 18, 2015 — PROVIDENCE — Lobsters are already slowly moving out of southern New England as waters warm, but the iconic crustacean faces another future threat as the climate changes.

As oceans absorb more carbon and become increasingly acidic, juvenile lobsters likely will have a harder time growing and forming strong shells to protect them from predators, according to a recent University of Rhode Island study.

“I’m not sure yet what the mechanism is that is affecting their growth,” URI doctoral student Erin McLean, who led the research, said. “But it takes energy for them to regulate the increased acidity, which is energy they cannot then put toward growth.”

And it’s not just lobsters that could be harmed by the oceans’ changing pH levels. Shellfish populations in Rhode Island and Massachusetts in general are among the most vulnerable in the United States to ocean acidification, according to a recent study in the journal Nature Climate Change.

The study identified the two states among 15 at-risk areas in the nation because colder, northern waters, such as Narragansett Bay, Buzzards Bay and Nantucket Sound, are absorbing more carbon dioxide from the atmosphere and acidifying faster than warmer waters.

Other more localized factors are also playing a part, including nutrient pollution from fertilizers and sewage systems that can add more carbon to the water and the flow of fresh water from poorly buffered rivers, such as the Blackstone in Rhode Island or the many waterways that drain into the Gulf of Maine, which lack minerals to mitigate the effects of acid. Shallow coastal waters also are more susceptible to changes in the ocean’s chemistry.

About a quarter of all carbon emissions from power plants, cars and other sources are absorbed by the oceans, making them more acidic and reducing carbonate levels. Shellfish use carbonates to make their shells, and when fewer of the compounds are available, organisms must expend more energy to build shells and less on eating and survival, researchers say.

WAITT INSTITUTE: Top 15 Ocean Conservation Wins of 2015

The Waitt Institute is a non-profit organization based in Washington, DC. It was founded in 2005 by Ted Waitt (co-founder of Gateway Computers) to foster exploration and discovery. The focus of the Waitt Institute has shifted in recent years, and today its mission is “empowering communities to restore their oceans to full productivity.” To achieve this, the Waitt Institute directs its efforts toward fostering deep collaborations with local governments and communities to create comprehensive ocean zoning and management solutions.

December 23, 2015 — Overfishing, climate change, habitat destruction, and pollution remain major threats to the world’s ocean. But amidst all that there is some seriously good ocean conservation news worth celebrating. So, to continue the tradition started last year with listing 14 Ocean Conservation Wins of 2014, here’s a rundown for 2015 that will hopefully fill you with #OceanOptimism. These wins represent the diligent efforts of organizations and individuals too numerous to list, so let’s just start with a blanket shoutout to all of #TeamOcean for a great year.

#1. Over 2 million km2 of ocean was protected in big new marine reserves. Marine reserves are areas completely closed to fishing, and 2015 saw more ocean protected in a single year than ever before. Chile created Desventuradas Marine Park (297,000 km2), and Easter Island Marine Park 631,000 km2). New Zealand created Kermadec Ocean Sanctuary (620,000 km2), Palau created Palau National Marine Sanctuary (500,000 km2), the UK announced the Pitcairn Island Reserve (833,000 km2), and protected areas are in the works for Patagonia. However, there is a broad consensus that 30% of the ocean should be fully protected in reserves, and these new designations only get us up to 1% – but we’ll take it!

#2. New technology is being developed to combat illegal fishing. Designating all these new reserves means little without enforcement, and we can’t enforce unless we know what’s happening out on the water. One big tech effort launched this year is Global Fishing Watch, a partnership between Skytruth, Google, and Oceana to track fishing vessels and identify illegal fishing. Another similar program is the Pew Charitable Trust’s Virtual Watch Room. These technologies are in prototype phase and need significant improvement before they live up to expectations, but it’s a promising and exciting development.

#3. Illegal fishing boats are being chased down and caught! Sea Shepherd chased a pirate fishing boat on Interpol’s most wanted list for 10,000 miles, until the boat sank (potentially on purpose to drown the evidence of illegal fishing). Another boat was chased for four days, caught, and fined $2 million for illegally fishing in the Phoenix Islands Protected Area. Blackfish and Environmental Justice Foundation have also been stepping up to make sure enforcement happens, but hopefully we can soon rely on law enforcement organizations, not environmental groups, to do this work.

Marine Protected Areas: are they conservation measures?

October 28, 2015 — Billionaire philanthropist Richard Branson recently composed a brief article on his website to applaud recent efforts to expand marine protected areas (MPAs) around the world and to call for widespread no-take MPAs (marine reserves) on the high seas and in the exclusive economic zones of the developed world.

Of the efforts Branson highlights as positive steps forward, he cites The Bahamas efforts to protect at least 20% of its marine environment by 2020, the recent and controversial Ross Sea MPA proposal, and recent efforts by Pacific Island nations like Palau to fully protect upwards of 80% of its waters. Branson explains that, “science suggests we need to fully protect very large areas of ocean from destructive and extractive activities, so that at least 30% of the global ocean is fully protected,” but only 3% is currently marine reserve.

Branson believes the, “combination of overfishing, pollution and warming and acidifying seas,” can be alleviated by widespread, internationally agreed upon marine reserves:

“Now is the time for a massive groundswell that reflects the realities of the 21st century. So instead of destroying life in the sea, we must regenerate and rebuild it. Marine Protected Areas across the globe are the key to making sure this happens. From small to large, from the tropics to the icy frontiers, we need protection and we need to get moving on all fronts.”

Comment by James H. Cowen, Louisiana State University

Marine Protected Areas (MPAs) have become, in the eyes of many scientists, NGOs and lay people (most recently Richard Branson, CEO and owner of the Virgin empire), a solution for the overexploitation of fish populations and other marine aquatic animals (corals, sponges, gastropods, etc.) that are contained within their boundaries (Protect Planet Ocean) Many supporters of MPAs rightly acknowledge the many threats to the ocean, including climate change, ocean acidification, pollution, land based runoff, plastics, and overfishing. Then as a solution to these problems MPAs are proposed when, in fact, they impact none of these except legally regulated fishing, especially in the developed world where most fisheries are well managed. It is also important to note that most MPAs exclude commercial fishing, while recreational fishing is permitted. A Sciences paper published in 2004 indicated that recreational fishers account for 23% of the total US landings of the most relevant species (snappers, grouper, sea basses, several species of drums, etc.). Given the likelihood that recreational fishing mortality has increased since 2004, and is higher in MPAs the relevant species groups listed above are again indicative of poor planning.

Remember the Oceans!

November 25, 2015 — On Nov. 30, more than 140 world leaders, including President Obama, will meet in Paris for the beginning of a historic two-week conference on climate change. There’s already been a flurry of voluntary national pledges, increasing confidence that the meeting will likely result in the first global agreement on emissions reductions. What they won’t be discussing, however (due to diplomatic quirks), is the effect of climate change on the world’s largest and most important ecosystem: the oceans.

That’s a shame. As I wrote this summer in Rolling Stone, there’s increasing evidence that the world’s oceans are nearing the point of no return. They’re getting hit with a double whammy—rising temperatures and acidification—that together are forcing fundamental changes to the basis of the planet’s food chain.

So far, the oceans have absorbed about 93 percent of all the additional heat energy trapped by rising greenhouse gas concentrations. That’s already prompted the loss of about 40 percent of the world’s coral reefs, accelerated by a series of worldwide bleaching events in which exceptionally warm water temperatures prompt normally symbiotic algae to become toxic—the most recent of which was just this year. Since coral reefs—the “rainforests of the sea”—support a quarter of all marine life on just 0.1 percent of the ocean area, a mass extinction may already be underway. If we lose the oceans, we lose everything.

Water temperatures this year in the North Pacific have surged to record highs far beyond any previous measurements. That means krill and anchovies have been forced into a narrow corridor of relatively cooler water close to the shore, and predators like whales are feasting on the dregs of an ecosystem. Along the coast of California, there’ve been sightings of rarely present species such as white pelicans, flying fish, Mexican red crabs, and nearly extinct basking sharks. Last year, a subtropical Humboldt squid was caught in southern Alaska—along with a thresher shark that was also far from its natural range. After a startling number of starving baby California sea lions began washing up on shore a couple of years ago, a colony has taken up residence in the Columbia River in Oregon. Marine life is moving north, adapting in real-time to the warming ocean. But for how much longer?

Members of Congress urge disaster relief for Dungeness crab fishermen

November 25, 2015 — In a bit of good news for California’s beleaguered crab fishermen, four members of Congress announced Tuesday they would call for federal disaster relief in the unlikely event the state’s commercial fishing season for Dungeness crab is canceled altogether.

In a letter to Gov. Jerry Brown, the representatives urged the governor to “stand ready” to ask U.S. Secretary of Commerce Penny Pritzker to provide compensation to fishermen and businesses if the crab season — postponed indefinitely Nov. 6 because of high levels of a biotoxin called domoic acid — is wiped out.

The congressmen and congresswomen who signed the letter — Rep. Lois Capps, D-Santa Barbara; Rep. Sam Farr, D-Carmel; Rep. Jared Huffman, D-San Rafael; and Rep. Jackie Speier, D-Hillsborough — represent coastal communities affected by the closure. Last season fishermen earned nearly $67 million from Dungeness crab in California.

To catch a fishing thief, SkyTruth uses data from the air, land and sea

November 24, 2015 — No one knows how much illegal fishing goes on in the oceans. They’re too vast to patrol. But a small nonprofit is helping governments track down seafood pirates by using powerful software, digital maps and publicly available data.

That nonprofit, SkyTruth, is led by a 52-year-old geologist named John Amos. It has fewer than a dozen employees and operates out of rural Shepherdstown, West Virginia – population: 2,140. Yet last spring, SkyTruth used its data to help the government of the Pacific island nation Palau track down a Taiwanese fishing ship whose holds were filled with illegally caught tuna and shark fins.

“Busting the bad guys is sexy,” says Amos, but he has bigger things in mind. In partnership with Google and Oceana, an international conservation and advocacy group, SkyTruth is building Global Fishing Watch, a website that allows the public to track fishing activities and outlaws and enable seafood purveyors to assure that the fish they are buying comes from sustainable fisheries. It also plans to provide data to researchers.

Meantime, SkyTruth does pathbreaking work around oil spills, mountaintop coal mining and hydraulic fracturing – for example, tracking pollution from unconventional oil and gas drilling, and using crowdsourcing to track the growth of fracking.

SkyTruth was among the nonprofits and companies showcased 18 November at Wired in the Wild: Can technology save the planet?, a daylong conference in Washington DC organized by World Wildlife Fund to highlight ways in which technology can support conservation. Participants heard about deploying drones to survey wildlife, attaching sensors to rhinos to help identify poachers and using submersibles to take marine biologists deep below the surface of the oceans to study coral.

Congress to vote on bill to ban microbead hygiene products in US

November 18, 2015 — US lawmakers are to decide whether to ban personal care products containing microbeads – minuscule pieces of plastic considered harmful to the environment – after proposed legislation was approved by a bipartisan committee.

Microbeads, typically under 5mm in size, are used as abrasive exfoliants in products such as toothpastes and facial cleaners. They often evade water filtration systems and flow into rivers, lakes and streams, where they can be mistaken for food by fish. Pollutants can bind to the plastic, causing toxic material to infect fish and, potentially, the humans that consume them.

The US House energy and commerce committee has unanimously approved the Microbead Free Waters Act of 2015, which was introduced by Frank Pallone, a Democrat, and Fred Upton, a Republican who acts as committee chairman.

The bill would start the phaseout of microbeads from products in the US from 1 July 2017. The federal legislation, if passed, will follow action taken by several states. Last month, California finalised a bill that phases out microbeads from 2020. This follows action taken by Illinois last year, which became the first state to ban the production, manufacture or sale of personal care products containing microbeads.

NORTH CAROLINA: Rains keeping shellfishing waters closed

November 9, 2015 — SOUTHEASTERN N.C. — For 61 years parishioners of Dixon Chapel United Methodist Church in Varnamtown have gathered for an oyster roast on the first Saturday in November. But the 62nd roast won’t happen until after the holidays, thanks to heavy rains that have closed local waters to shellfish harvest.

For much of the last month, nearby Lockwoods Folly Inlet has been closed indefinitely — a post on the church’s Facebook page tells members that the roast might be rescheduled around the end of oyster season early next year. Even before the season opened Oct. 15, the threat of pollution from heavy rains has kept shellfish harvesters waiting throughout Southeastern North Carolina.

As soaking rains wash stormwater runoff into the Cape Fear River and Intracoastal Waterway, the N.C. Division of Marine Fisheries issues the closures as a precautionary measure. An oyster filters about 50 gallons of water per day, and if that water is contaminated with fecal matter or pollutants from roadways, it’s likely to end up in the shellfish.

Closures are still in effect for some waters from the state line to Wrightsville Beach, and Patti Fowler, chief of the division’s Shellfish Sanitation and Water Quality section, said more rain in the forecast means its unclear how soon fishermen can get back to the oyster beds.

RICHARD SPINRAD & IAN BOYD: Our Deadened, Carbon-Soaked Seas

October 15, 2015 — Ocean and coastal waters around the world are beginning to tell a disturbing story. The seas, like a sponge, are absorbing increasing amounts of carbon dioxide from the atmosphere, so much so that the chemical balance of our oceans and coastal waters is changing and a growing threat to marine ecosystems. Over the past 200 years, the world’s seas have absorbed more than 150 billion metric tons of carbon from human activities. Currently, that’s a worldwide average of 15 pounds per person a week, enough to fill a coal train long enough to encircle the equator 13 times every year.

We can’t see this massive amount of carbon dioxide that’s going into the ocean, but it dissolves in seawater as carbonic acid, changing the water’s chemistry at a rate faster than seen for millions of years. Known as ocean acidification, this process makes it difficult for shellfish, corals and other marine organisms to grow, reproduce and build their shells and skeletons.

About 10 years ago, ocean acidification nearly collapsed the annual $117 million West Coast shellfish industry, which supports more than 3,000 jobs. Ocean currents pushed acidified water into coastal areas, making it difficult for baby oysters to use their limited energy to build protective shells. In effect, the crop was nearly destroyed.

The Chesapeake Bay Is Turning Into Plastic Soup

July 22, 2015 — They’re in the oceans, in the Great Lakes, and now it turns out they’re fouling the Chesapeake Bay—microplastics, the remnants of unrecycled products that are damning the world’s water to seemingly eternal pollution.

The presence of microplastics—from broken-up containers to ingredients in bathroom products—has been established in four Bay tributaries by researchers at the University of Maryland, NOAA, and elsewhere. “Microplastics were found in all but one of 60 samples, with concentrations ranging over 3 orders of magnitude (<1.0 to >560 g/km2),” they write in Environmental Science and Technology. “Concentrations demonstrated statistically significant positive correlations with population density and proportion of urban/suburban development within watersheds.”

One can deduce that with more growth around Baltimore and Washington, D.C., we can expect to see yet more microplastics. See, and maybe eat, too, as scientists recently discovered the stuff’s being consumed by plankton and passed up the food chain. That’s bad news for marine animals, which can starve on the nutrientless substances or die of stomach obstructions, and possibly for humans, as plastics leach chemicals into fish with unknown impacts on our health. (They might also affect that treasured Chesapeake delicacy, blue crabs, as crabs both eat and breathe in microplastics.)
