China’s Island Building Hurts Environment, U.S. Report Says

April 13, 2016 — China’s reclamation work in the South China Sea may have destroyed coral reefs, damaged fisheries in a region heavily dependent on seafood and breached international law on protecting the environment, according to a report to U.S. Congress.

“The scale and speed of China’s activities in the South China Sea, the biodiversity of the area, and the significance of the Spratly Islands to the ecology of the region make China’s actions of particular concern,” an April 12 report prepared for the U.S.-China Economic and Security Review Commission said.

China reclaimed about 3,000 acres of land on seven features it occupies in the Spratly islands of the South China Sea between December 2013 and October 2015, the report said. Vietnam has reclaimed about 80 acres, Malaysia 70 acres, the Philippines 14 acres and Taiwan eight acres, according to the U.S. Department of Defense.

Is global warming causing marine diseases to spread?

March 29, 2016 — PORTLAND, Maine –Global climate change is altering the world’s oceans in many ways. Some impacts have received wide coverage, such as shrinking Arctic sea ice, rising sea levels and ocean warming. However, as the oceans warm, marine scientists are observing other forms of damage.

My research focuses on diseases in marine ecosystems. Humans, animals and plants are all susceptible to diseases caused by bacteria, viruses, parasites and fungi. Marine diseases, however, are an emerging field.

Infectious agents have the potential to alter ocean life in many ways. Some threaten our food security by attacking important commercial species, such as salmon. Others, such as bacteria in oysters, may directly harm human health. Still others damage valuable marine ecosystems – most notably coral reefs.

To anticipate these potential problems, we need a better understanding of marine diseases and how climate change affects their emergence and spread.

Acidic Ocean Leads to Warped Skeletons for Young Coral

February 19, 2016 — Rising emissions of carbon dioxide create twin threats for coral in oceans around the world: warmer temperatures, which can cause mass bleachings, and ocean acidification, which can hinder the animals’ ability to build reefs.

But a new study published on Friday in the journal Science Advances suggests that ocean acidification may be the bigger worry in some waters.

Studying a chain of remote Australian islands in the Indian Ocean, researchers found that more acidic waters (those that have absorbed more atmospheric carbon dioxide) cause serious skeletal deformities in juvenile coral in subtropical waters.

Using 3-D imaging techniques, they saw that young coral from the Houtman Abrolhos islands developed skeletons that were missing sections or had very porous and fragile surfaces.

Other studies have shown similar effects of ocean acidification, but the researchers also discovered something that had not been seen in earlier studies of tropical coral development — higher temperatures didn’t have a negative effect on coral skeleton formation.

Sunken sanctuary: Former Omega Protein WWII-era vessel becomes artificial reef

December 15, 2015 — For much of the last decade, the MV Shearwater caught menhaden by the ton but in its new life, as part of the Del-Jersey-Land reef 26-miles off the coast, it will become a fish habitat and diving destination in the state’s artificial reef program.

The ship didn’t go easy into the deep last week. The stern sank first and the ship started to turn leaving just the bow out of the water. It took about six hours to fully sink after the seacocks opened and the interior compartments flooded.

The 176-foot-long vessel went down in 120 feet of water. It lays about one-half nautical mile from the 568-foot long USS Arthur W. Radford, a former Navy destroyer. The Radford was sunk at the artificial reef site in 2011 and has become a popular destination for divers and anglers.

“About three weeks ago, a state-record bluefish was caught there,” said Jeff Tinsman, the state artificial reef coordinator.

“These old freighters make ideal reefs because of the voids and cavities in them – they’re really the perfect sanctuary for fish,” Tinsman said. “But not long after this ship sinks, the fish will start to come ‘outside’ it to feed. Within a few weeks, blue mussels, sponges, barnacles and soft corals will attach themselves to the structure, and in about a year, the reef will be fully productive, for fish and fishermen alike.”

Baby fish will be lost at sea in acidified oceans

December 15, 2015 — The ability of baby fish to find a home, or other safe haven, to grow into adulthood will be severely impacted under predicted ocean acidification, University of Adelaide research has found. 

Published today in the journal Proceedings of the Royal Society B, the researchers report the interpretation of normal ocean sound cues which help baby fish find an appropriate home is completely confused under the levels of CO2 predicted to be found in oceans by the end of the century.

“Locating appropriate homes is a crucial step in the life cycle of fish,” says Tullio Rossi, PhD candidate with the University’s Environment Institute. “After hatching in the open ocean, baby fish travel to reefs or mangroves as safe havens to feed and grow into adults.

“Baby fish can find those places through ocean noise: snapping shrimps and other creatures produce sounds that the baby fish follow.

“But when ocean acidity increases due to increased CO2, the neurological pathways in their brain are affected and, instead of heading towards those sounds, they turn tail and swim away.”

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?

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.

Fishermen, Conservationists, and Regulators Honored for Landmark Coral Preservation Efforts

October 29, 2015 – The following was released by the Garden State Seafood Association (GSSA):

TRENTON, N.J. — Representatives from the Garden State Seafood Association (GSSA) are among those being honored for their efforts to preserve 38,000 square miles of Mid-Atlantic ocean habitat, and extend valuable protections to vulnerable coral reefs. Ernie Panacek, President of the GSSA, Richard Robins, Chairman of the Mid-Atlantic Fishery Management Council (MAFMC), and Jay Odell, Director of the Mid-Atlantic Marine Program at the Nature Conservancy, were presented with this year’s Regional Ocean Champions Award, given by the Urban Coast Institute at Monmouth University, at the Institute’s 11th Annual Future of the Ocean Symposium.

Dr. Sylvia Earle, Explorer in Residence at the National Geographic Society, and Terry Garcia, the Chief Science and Exploration Officer at the National Geographic Society, were presented with the National Champions of the Ocean Award.

Earlier this year, the MAFMC approved the Deep Sea Corals Amendment, which created a series of “deep sea coral zones,” totaling over 38,000 square miles, to be closed off to fishing gear that comes into contact with the seafloor. These zones protect the fragile coral ecosystems and other notable habitats from potentially harmful disturbances.

“The Deep Sea Corals Amendment presented the Council with an opportunity of a lifetime to conserve sensitive deep sea corals and their associated marine ecosystems in the Mid-Atlantic,” said Mr. Robins. “What was so unique about this action was that we used a participatory approach to defining the protected areas, which allowed a broad range of stakeholders to reach consensus on what those boundaries should be.”

This participatory process brought together Council members, fishermen and industry representatives, scientists, and other stakeholders in a collaborative and cooperative effort.

“The fishing industry has a lot to offer intellectually,” said Mr. Panacek. “When there is mutual respect, meaningful results can be achieved.”

The resulting protections have been widely praised, by environmentalists and fishermen alike. Peter Baker, of the The Pew Charitable Trusts, wrote in a post featured on the Conservation Law Foundation’s Talking Fish blog that the Amendment would “cement a conservation legacy for the Mid-Atlantic.”

Industry representatives, such as GSSA Executive Director Greg DiDomenico, see the open and inclusive process that lead to the Amendment as an example for fisheries managers nationwide, one that demonstrates the value of stakeholder engagement and proves that the fisheries management system established by the Magnuson-Stevens Act works.

“The process in the Mid-Atlantic should be the model for developing targeted habitat protection in New England,” said Mr. DiDomenico. “An open, collaborative process is the best way to build on these efforts.”  

The Champion of the Ocean Awards honor those who have “demonstrated sustained leadership in advancing a future in which coasts and oceans are clean, safe, sustainably managed and preserved for the benefit and enjoyment of future generations.”

This is the second time this year that GSSA has been honored for its conservation work. Mr. DiDomenico, along with MAFMC Chairman Robins, were recognized as Conservation Leaders by the New York Aquarium in a September ceremony held at the Central Park Zoo.

How we are all contributing to the destruction of coral reefs: Sunscreen

October 20, 2015 — The sunscreen that snorkelers, beachgoers and children romping in the waves lather on for protection is killing coral and reefs around the globe. And a new study finds that a single drop in a small area is all it takes for the chemicals in the lotion to mount an attack.

The study, released Tuesday, was conducted in the U.S. Virgin Islands and Hawaii several years after a chance encounter between a group of researchers on one of the Caribbean beaches, Trunk Bay, and a vendor waiting for the day’s invasion of tourists. Just wait to see what they’d leave behind, he told the scientists – “a long oil slick.” His comment sparked the idea for the research.

Not only did the study determine that a tiny amount of sunscreen is all it takes to begin damaging the delicate corals — the equivalent of a drop of water in a half-dozen Olympic-sized swimming pools — it documented three different ways that the ingredient oxybenzone breaks the coral down, robbing it of life-giving nutrients and turning it ghostly white.

Yet beach crowds aren’t the only people who add to the demise of the coral reefs found just off shore. Athletes who slather sunscreen on before a run, mothers who coat their children before outdoor play and people trying to catch some rays in the park all come home and wash it off.

Cities such as Ocean City, Md., and Fort Lauderdale, Fla., have built sewer outfalls that jettison tainted wastewater away from public beaches, sending personal care products with a cocktail of chemicals into the ocean. On top of that, sewer overflows during heavy rains spew millions of tons of waste mixed with stormwater into rivers and streams. Like sunscreen lotions, products like birth-control pills contain chemicals that are endocrine disruptors and alter the way organisms grow. Those are among the main suspects in an investigation into why male fish such as bass are developing female organs.

Bottom fishing banned in Danish marine parks

October 7, 2015 — Denmark, Germany and Sweden will stop all fishing activities over highly sensitive ‘bubbling’ reefs and will also end fishing with damaging bottom gear over reefs in protected Danish waters of the Baltic Sea and Kattegat.

This follows a new EU regulation – jointly recommended by Denmark, Germany and Sweden – which bans fishing activities in 10 Natura 2000 protected sites, although the fisheries restrictions only apply to specific reef zones within these areas.
