2014-09-09. Biologists try to dig endangered pupfish out of its hole. Excerpt: Scientists estimate that fewer than 100 Devils Hole pupfish remain in their Mojave Desert home, but a conservation biologist at the University of California, Berkeley, is giving important guidance in the efforts to rescue them by establishing a captive breeding program. Considered the world’s rarest fish, with one of the smallest geographic ranges of any wild vertebrate, the tiny pupfish (Cyprinodon diabolis) – about one-inch long as an adult – neared extinction in spring 2013 when populations dropped to an all-time low of 35 observable pupfish. ...the species is considered critically endangered. ...The pupfish is found only in a limestone cavern in the Devils Hole geothermal pool, about 60 miles east of Death Valley National Park. ...The oxygen-poor water in Devils Hole stays a toasty 92-93 degrees Fahrenheit, around the upper limits of temperature tolerated by most fish. A study published last month found that climate change is contributing to the warming of the water in Devils Hole, negatively affecting the ability of eggs to hatch and larvae to survive. Pupfish populations also may have declined due to reductions in food supply and genetic diversity.... http://newscenter.berkeley.edu/2014/09/09/endangered-devils-hole-pupfish/.

2014-09-05. A Whale of a Recovery for California’s Blue Whales. Excerpt: The blue whale, the biggest animal on the planet, was hunted with abandon in the Pacific Ocean until the early 1970s. The species has been rebounding ever since,  ...Scientists at the University of Washington (Cole C. Monnahan, Trevor A. Branch and André E. Punt) have just published research finding that the West Coast blue whale population of around 2,200 individuals appears to be approaching its pre-slaughter size, with the slowing growth a function of the carrying capacity of the marine ecosystem. Collisions with ships remain a problem, the scientists write, but should not affect the whales’ prospects....  http://dotearth.blogs.nytimes.com/2014/09/05/a-whale-of-a-recovery-for-californias-blue-whales/.

2014-08-24. What's Killing the Bay Area's Oysters? Excerpt: Signifiers of the good life, local bivalves may be harbingers of another phenomenon: species extinction. ...roughly 7 million oysters ... the five oyster farms on Tomales Bay sell each year to local restaurants and bars. ...Though Hog Island’s inventory had restabilized by 2013, ...We just couldn’t supply the product. It was painful—and still is because we’re not over it. The culprit? Ocean acidification—climate change’s caustic cousin—caused by rising carbon dioxide emissions. ...In 2005, the National Oceanic and Atmospheric Administration began reporting that hatcheries throughout the West Coast were seeing steep declines in production, putting the $84 million industry in jeopardy. Hatchery staff and scientists scrambled to pinpoint the cause, .... It wasn’t until a year later that [Alan] Barton [or Whiskey Creek shellfish hatchery in Tillamook, Oregon] solved the mystery that had stumped scientists. On an ordinary summer day that was marred by a particularly bad die-off, he decided to test the pH levels in the tanks. ...Lo and behold, the pH level of the water was drastically lower (read: more corrosive) than usual. ...because the acidification is exacerbated by carbon dioxide emissions, every year it gets a little worse. ...These days, we release roughly 70 million tons per day—and the oceans soak up nearly a third of that. The result? On average, the sea is 30 percent more acidic than it was 200 years ago. And in the last decade, it began passing the point where young oysters can survive. It’s not necessarily the acidity that causes problems for the oysters, but rather the concomitant lack of carbonate ions in the water. Shellfish use these free-floating ions to build their shells. When seawater absorbs carbon dioxide, the number of carbonate ions available for the shellfish is reduced. “A baby oyster is trying to eat, grow, move around, and make a shell. So if it spends more energy trying to make a shell, then something else in that equation is going to suffer,” says Tessa Hill, a scientist with UC Davis who studies the impacts of rising carbon dioxide levels on native shellfish. “I say it’s like balancing your checkbook—you can’t spend a lot of energy on one thing without cutting back in some other category.” http://modernluxury.com/san-francisco/story/whats-killing-the-bay-areas-oysters.

2014-07. What seafood guzzles the most gas? Excerpt: ...diesel is the single largest expense for the fishing industry and its biggest source of greenhouse gases. Not all fish have the same carbon finprint, however, and a new study reveals which ones take the most fuel to catch. Robert Parker, a Ph.D. student at the University of Tasmania, Hobart, in Australia, and Peter Tyedmers, an ecological economist at Dalhousie University in Halifax, Canada, analyzed more than 1600 records of fuel use by fishing fleets worldwide. They ... reported online this month in Fish and Fisheries. 7. Sardines: 71 liters ...Icelandic herring and Peruvian anchovies are the least fuel-intensive industrial fisheries known, caught with just 8 liters of fuel per ton of fish. 6. Skipjack tuna: 434 liters ...5. Scallops: 525 liters ...4. North American salmon: 886 liters ...3. Pacific albacore: 1612 liters ...2. Sole: 2827 liters ...1. Shrimp and lobster: 2923 liters ...How does wild seafood compare with other kinds of animal protein? The median fuel use in the fisheries is 639 liters per ton. In terms of climate impact, that’s equivalent to a bit more than 2 kilograms of carbon dioxide emitted for each kilogram of seafood landed. Chicken and farmed salmon and trout are roughly the same, but beef is significantly higher at 10 kg of carbon dioxide per kg of live animal. “If you’re looking at having a green diet, you want to transition away from beef,” Parker says.... http://news.sciencemag.org/climate/2014/07/what-seafood-guzzles-most-gas. by Erik Stokstad, Science.

2014-06-02. Big Island Senator: Whales and Honu Have Too Many Protections. Excerpt: Sen. Malama Solomon says people should be prioritized over whales and green sea turtles. She wants NOAA to delist them as endangered. ...Hawaii’s whale population has increased 20-fold since the days of Gov. George Ariyoshi.... Last year, a group of Hawaii fishermen filed a petition with NOAA to have the whales removed from the endangered species list, noting their growing numbers. The humpback whales in the North Pacific have increased to more than 21,000 today, from about 1,400 in the mid-1960s, according to the Associated Press. The global whale population was decimated by the commercial whaling industry beginning in the early 20th century. In 1973, the federal government made it illegal to hunt or harm them. They are protected not only by the Endangered Species Act, but also by the Marine Mammal Protection Act, Hawaii wildlife laws and the National Marine Sanctuaries Act. In 1992, the U.S. Congress created the Hawaiian Islands Humpback Whale National Marine Sanctuary, jointly managed by NOAA and the state of Hawaii. ...The “waters around the main Hawaiian islands constitute one of the world’s most important North Pacific humpback whale habitats, and the only place in U.S. coastal waters where humpbacks reproduce,” according to NOAA’s web site. ...The population of green sea turtles in Hawaii has also increased since they were placed on the endangered species list in 1978. ...increased six-fold since the 1970s, according to The Garden Island. NOAA is currently reviewing whether they should be delisted.... By Sophie Cocke, Honolulu Civil Beat. http://www.civilbeat.com/2014/06/big-island-senator-whales-honu-many-protections/

2014-01-15. Key species of algae shows effects of climate change over time. Excerpt: A study of marine life in the temperate coastal waters of the northeast Pacific Ocean shows a reversal of competitive dominance among species of algae, suggesting that increased ocean acidification caused by global climate change is altering biodiversity. The study, published online January 15, 2014, in the journal Ecology Letters, examined competitive dynamics among crustose coralline algae, a group of species living in the waters around Tatoosh Island, Washington. These species of algae grow skeletons made of calcium carbonate, much like other shelled organisms such as mussels and oysters. As the ocean absorbs more carbon dioxide from the atmosphere, the water becomes more acidic. Crustose coralline algae and shellfish have difficulty producing their skeletons and shells in such an environment, and can provide an early indicator of how increasing ocean acidification affects marine life...  http://www.uchospitals.edu/news/2014/20140115-mccoy.html University of Chicago Medical Center

2013-12-24. When Whale Watching Turns Deadly.   Excerpt: Humpback whales are facing new dangers in Hawaiian waters, where more than 10,000 of the cetaceans congregate from December to April to calve and breed. That’s the conclusion of an analysis of historical records of ship strikes on humpback whales (Megaptera novaeangliae) in the seas around the Hawaiian Islands between 1975 and 2011. In that 36-year period, 68 such strikes were reported, ...more than 63% of the collisions involved calves and subadults, ...younger animals are particularly susceptible to being struck, most likely because they spend more time at the surface to breathe than do adults. ...the number of strikes has steadily increased over the years, ...and not because there are more whales. Instead, the increase is apparently due to tourism. The majority of vessels that have collided with whales in Hawaii are small- to medium-sized boats, less than 21.2 meters in length, the scientists say, which happens to be the size of commercial whale-watching vessels. Federal regulations require these boats to remain at least 100 yards distance from the humpbacks. ...The majority of collisions occurred when the vessels were travelling at 10 to 19 knots, ...too fast to avoid colliding with the very animals the skippers and tourists have come out to watch. http://news.sciencemag.org/plants-animals/2013/12/scienceshot-when-whale-watching-turns-deadly.

2013-11-03. U.S. agency proposes rules to protect bluefin tuna.  Excerpt:  Pity, for a moment, the poor Atlantic bluefin tuna. It’s not bad enough that its population has been decimated by diners’ seemingly insatiable appetite for sushi. Or that the 2010 Deepwater Horizon oil spill occurred at the height of its spawning season, in its only known Western spawning grounds. No, bluefin also are plagued by another long-standing problem: They are inevitably caught by long-line fishermen trying to hook bigger, healthier schools of yellowfin tuna, swordfish and big-eye tuna. Under government regulations, the fishermen are allowed to bring a small number of the carefully regulated and valuable fish to shore for sale, but most of them die on hooks hanging from 20-mile fishing lines and are discarded at sea. ...By one estimate, 111 metric tons of bluefin were killed this way in one year. The “bycatch” problem is slowing efforts to rebuild the bluefin population in the western Atlantic, which is at 36 percent of the 1970 level, according to the International Commission for the Conservation of Atlantic Tunas. ...Now, the National Marine Fisheries Service (NMFS), the U.S. government agency that regulates offshore fishing, ... is proposing ... sharply cut back the number of bluefin tuna that individual fishing vessels are allowed to capture accidentally, setting a quota for each boat and requiring fishermen to include the bluefin they discard at sea under that cap. The NMFS also would change the long-standing formula by which it calculates the number of pounds of bluefin tuna that a long-liner may legally bring to shore for sale. Any vessel that exceeds its cap for accidentally caught bluefin wouldn’t be able to leave the dock to fish for other species, according to the proposal.... http://www.washingtonpost.com/national/health-science/us-agency-proposes-rules-to-protect-bluefin-tuna/2013/11/03/e3b653d8-4339-11e3-a624-41d661b0bb78_story.html.

2013-10-29. Just how badly are we overfishing the oceans?  Excerpt:  Humans now have the technology to find and catch every last fish on the planet. Trawl nets, drift nets, longlines, GPS, sonar... As a result, fishing operations have expanded to virtually all corners of the ocean over the past century. ...That, in turn, has put a strain on fish populations. The world's marine fisheries peaked in the 1990s, when the global catch was higher than it is today. And the populations of key commercial species like bluefin tuna and cod have dwindled, in some cases falling more than 90 percent. So just how badly are we overfishing the oceans? Are fish populations going to keep shrinking each year — or could they recover? ...The pessimistic view, famously expressed by fisheries expert Daniel Pauly, is that we may be facing "The End of Fish." One especially dire 2006 study in Science warned that many commercial ocean fish stocks were on pace to “collapse” by mid-century — at which point they would produce less than 10 percent of their peak catch.  ...Other experts have countered that this view is far too alarmist. A number of countries have worked hard to improve their fisheries management over the years, including Iceland, Australia, New Zealand, and the United States. "The U.S. is actually a big success story in rebuilding fish stocks," Ray Hilborn, a marine biologist at the University of Washington, told me last year. Overfishing isn't inevitable. We can fix it.... http://www.washingtonpost.com/blogs/wonkblog/wp/2013/10/29/just-how-badly-are-we-overfishing-the-ocean/. Brad Plumer, The Washington Post.

2013-06-10.  Small and wild: how to feed fish to the world. Excerpt: ...Andy Sharpless, CEO of Oceana, ...ocean conservation organization, ..."People need to give up shrimp," he said, explaining that the fine nets used to catch them result in one of the highest levels of bycatch. The farmed fare isn't much better, since it requires that tropical forests and mangroves be cleared, and leaves destroyed earth in its wake, on account of the chemical additives and pesticides used. ...his new publication The Perfect Protein, ...suggests ...using wild ocean fish. Farmed fish ...fed by other fish are what we might call the danger fish: they do the most damage because we use up the wild fish we should really be eating.... Farmed salmon ...requires about five pounds of fishmeal to grow one pound. That meal typically comes in the shape of highly nutritious, rapidly reproducing forage fish like anchovies, sardines, and herrings.  ..."Farmed mussels, farmed oysters, farmed clams," said Sharpless, "are... dependent on healthier ocean bays where these are raised, shellfish farmers are what Sharpless calls "a wonderful ally for conservationists," because they're motivated to uphold healthy habitats. ... eating more of the small fry that exist lower down the food chain, the authors argue, like sardines and anchovies, [that] reproduce more quickly, grow faster, many exist around the world and they "are at least equally nutritious to the ones at the top of the food chain." They're also less likely to harbour toxins....  His book lists several recipes for dishes that explore the flavours of small forage fish: anchovies, sardines, and mackerel. Others call for farmed bivalves like clams and mussels. Tilapia, salmon, and catfish are deemed suitable too, if they come from sustainable wild populations. ...prawns aren't featured.... http://www.guardian.co.uk/environment/world-on-a-plate/2013/jun/10/fish-fishing.

2013-05-31.  Climate change study: 82 percent of Calif. native fish species risk extinction.  Excerpt: Climate change may cause the extinction of 82 percent of California's native fish species, including iconic ones such as Central Valley salmon and Delta smelt, according to a new study. The peer-reviewed study by fishery experts at UC Davis created a framework to measure how vulnerable numerous species are to climate change. It assesses habitat conditions, climate change projections and temperature sensitivity for the 121 native and 50 nonnative fish species that inhabit California. It found that 82 percent of the native species are at risk of extinction in the next 100 years, largely because climate change will make water temperatures too warm. For nonnative fish, which are generally more adaptable to warm water, only 19 percent are likely to die off. ...The study is available online at http://ht.ly/lyRR8 .... http://www.sacbee.com/2013/05/30/5459758/climate-change-study-82-percent.html.

2012 October 01. Worrisome Measure of Decline at Great Barrier Reef. By Emma Bryce, The NY Times. Excerpt: A study released today by the Australian Institute of Marine Science shows that the Great Barrier Reef — a Heritage Site frequently held up as one of the world’s most striking coral conservation successes — has experienced considerable decline since 1985, and without intervention, live coral cover is projected to decrease another 5 to 10 percent over the next 10 years. Over the last 27 years, the study found, coral cover across the 133,000-square mile stretch of the Great Barrier Reef has fallen to 13.8 percent over all, from 28 percent. The study broke down the causes of the decline, attributing 48 percent of coral loss to cyclones, 10 percent to coral bleaching and the remainder — 42 percent — to excessive spawning of destructive crown of thorns starfish. The starfish, believed by researchers to prosper when artificial nutrients increase in oceans, consume and destroy more than their fair share of live coral cover.....

2012 Sept 18. Getting Bluefin Tuna Off the Hook. By Kelly Slivka, The NY Times. Excerpt: In the Gulf of Mexico, many fishermen use longlines to fish for swordfish and yellowfin tuna, but they also end up catching Atlantic bluefin tuna, among other species. The International Union for Conservation of Nature lists the Atlantic bluefin as a threatened species and the Gulf of Mexico is known to be one of its spawning grounds, so purposefully fishing for the species has been forbidden in the gulf since 1982. However, the fishermen are allowed to catch some bluefins while fishing for other species — a loophole that the Pew Environment Group would like to close, said Tom Wheatley, who manages the organization’s Gulf Surface Longline Campaign…[by] collaborating on a pilot project with gulf swordfish and yellowfin tuna fishermen that involves testing two alternative fishing methods that tend to have a far smaller bluefin bycatch…

2012 July 06. Once-abundant West Coast oysters near extinction. By Paul Fimrite, SFGate. Excerpt: A disturbing nationwide decline in oysters and the life-giving reefs that they build is particularly dramatic in California, where the once-abundant native species has been virtually wiped out, according to a recent scientific study. The report, published in the scientific journal Proceedings of the Royal Society B, said Olympia oysters, once an integral part of the Native American diet and a staple during the San Francisco Gold Rush, are functionally extinct…The loss of native oysters - not to be confused with the farm-raised Japanese Pacific oysters - is a serious issue…oysters clean the water by filter feeding. A single oyster can filter up to 30 gallons of water a day, removing nitrogen and other pollutants…The oyster beds, or reefs, they create provide habitat for myriad fish, crabs and other creatures.….

2012 June 25. ‘Nature’s Masons’ Do Double Duty as Storytellers.  By Sean B. Carroll, New York Times.  Excerpt: GUBBIO, Italy — …Limestone is composed largely of crystallized calcium carbonate. Some of it comes from the skeletal remains of well-known creatures like corals, but much of the rest comes from less appreciated but truly remarkable organisms called foraminifera, or forams for short. Forams have been called “nature’s masons,” … these single-celled protists construct surprisingly complex, ornate and beautiful shells to protect their bodies. After forams die, their shells settle in ocean sediments…. While tiny relative to ourselves …, forams are extremely large for single-celled organisms, … largest forams can reach a few centimeters. ...Forams are a vital part of a “biological pump” that removes carbon dioxide from the atmosphere. When carbon dioxide dissolves in seawater, one reaction product is carbonate. In making their calcium carbonate shells, the large mass of so-called planktonic forams floating in the upper levels of the oceans sequester about one quarter of all carbonate produced in the oceans each year.
The increasing levels of carbon dioxide in our planet’s atmosphere, now at a greater level than at any time in the past 400,000 years, threaten to overwhelm this biological pump by inhibiting the formation of calcium carbonate shells. As more carbon dioxide dissolves in the ocean, the waters acidify, decreasing the concentration of carbonate and making it more difficult for these organisms to form calcium carbonate shells….

2012 May 15. Saving the Wonders of the Sea of Cortez. By Tim Folger, OnEarth. Excerpt: In 2009…a research team…conducted an extensive survey of the Sea of Cortez, documenting the effects of overfishing and habitat loss. Fish have completely disappeared from some reefs in the northern part of the sea. The absence of grazing fish may explain why bacteria now cover the reefs, a phenomenon referred to by one of the researchers as the rise of the slime. For much of the past decade, Aburto Oropeza has been working with scientists in the United States and Mexico to identify habitats that are crucial for the long-term viability of fisheries in the Sea of Cortez. His research suggests a practical and economical conservation strategy: to save the sea, and the livelihoods of those who depend on its bounty, it might be enough to protect -- with effective enforcement -- a few key clearly defined areas…Since the 1970s, parts of the Sea of Cortez have lost more than a quarter of their mangrove forests, and nationwide the rate of destruction has accelerated, with some 2 percent of the remaining mangroves across Mexico now being cleared each year....

2012 May 12. Sonar, blasts could hurt more sea life, Navy says. By Associated Press, SF Gate. Excerpt: The U.S. Navy says its training and testing using sonar and explosives could potentially hurt more dolphins and whales in Hawaii and California waters than previously thought. In the study, the Navy estimates its use of explosives and sonar could unintentionally cause more than 1,600 instances of hearing loss or other injury to marine mammals in one year. The service calculates that its use of explosives could inadvertently cause more than 200 marine mammal deaths a year....

2012 Apr 21. A Ban on Some Seafood Has Fishermen Fuming. By Abby Goodnough, The New York Times. Excerpt: GLOUCESTER, Mass. — Standing on the deck of his rusted steel trawler, Naz Sanfilippo fumed about the latest bad news for New England fishermen: a decision by Whole Foods to stop selling any seafood it does not consider sustainable. …Starting Sunday, gray sole and skate, common catches in the region, will no longer appear in the grocery chain’s artfully arranged fish cases. Atlantic cod, a New England staple, will be sold only if it is not caught by trawlers, which drag nets across the ocean floor, a much-used method here. “It’s totally maddening,” Mr. Sanfilippo said. “They’re just doing it to make all the green people happy.” Whole Foods says that, in fact, it is doing its part to address the very real problem of overfishing and help badly depleted fish stocks recover. It is using ratings set by the Blue Ocean Institute, a conservation group, and the Monterey Bay Aquarium in California. They are based on factors including how abundant a species is, how quickly it reproduces and whether the catch method damages its habitat. …Some question the need for grocery stores to reject certain American-caught fish when the government has already imposed its own conservation measures. Many of the nation’s fishermen now operate under federally created systems that allocate a yearly quota of fish….

2011 Nov 21. Northwest Oyster Die-offs Show Ocean Acidification Has Arrived.  By Elizabeth Grossman, Yale Environment 360.  Excerpt: …It’s hard to imagine that the fate of the oysters being raised here at the Whiskey Creek Shellfish Hatchery is being determined by what came out of smokestacks and tailpipes in the 1960s and ‘70s. But this rural coastal spot and the shellfish it has nurtured for centuries are a bellwether of one of the most palpable changes being caused by global carbon dioxide emissions — ocean acidification….
…Ocean acidification — which makes it difficult for shellfish, corals, sea urchins, and other creatures to form the shells or calcium-based structures they need to live — was supposed to be a problem of the future. But because of patterns of ocean circulation, Pacific Northwest shellfish are already on the front lines of these potentially devastating changes in ocean chemistry….
...Because of the way seawater circulates around the world, the deep water now washing ashore in Oregon and Washington is actually 30 to 50 years old and absorbed its CO2 long before the fall of the Berlin Wall. This time lag is important because oceans absorb about 50 percent of the CO2 released by burning fossil fuels, emissions that have been rising dramatically in recent decades. According to the National Oceanic and Atmospheric Administration (NOAA) ocean acidity has increased approximately 30 percent since the Industrial Revolution, and if we continue our current rate of carbon emissions, global oceans could be 150 percent more acidic by the end of the century than they have been for 20 million years…..

2011 August 7. The Last of the Lobstermen, Chasing a Vanishing Treasure. By Barton Silverman, The New York Times. Excerpt: It has been 12 years since a great die-off of lobsters in Long Island Sound rocked the local industry and stumped researchers. It lasted three days but wiped out an estimated nine-tenths of the catch, compared with two years earlier. Scientists blamed global warming, citing increased temperatures in the lower waters where lobsters live. Another culprit was pesticides like those deployed against the West Nile virus. The die-off began around the same time that the remnants of Hurricane Floyd swept over Long Island and, lobstermen believe, flushed pesticides into the Sound. The past 12 years have not been kind. Adding to the misery is a bacterial invasion that causes deformities in lobster shells and “reduces the marketability of the product,” said Antoinette Clemetson, a marine fisheries specialist with New York Sea Grant. “We’re in the worst possible environmental combination of factors. They’re simultaneous"…

2011 July 18. California mussels: 1st warming casualty? By Pat Brennan, The Orange County Register. Excerpt: The iconic California mussel could be among the first casualties of oceans made more acidic by global warming, a new study of the coastal shellfish shows. Scientists who grew mussel larvae in a bath of acidified water thought to match expected changes in ocean chemistry report thinner, weaker shells and smaller bodies in a newly published study.
"Indications from records are that acidity increased by about 30 percent in the last 250 years," Gaylord said.
…With little sign of a slackening of carbon dioxide, or CO2, emissions, changes in ocean chemistry seem almost inevitable, he said.
"These changes are going to proceed even if we stop emitting anymore CO2," Gaylord said. "Humans have made the commitment to an altered environment."

2011 July 9. Answer for Invasive Species: Put It on a Plate and Eat It. By Elisabeth Rosenthal, The NY Times. Excerpt: …An invasive species, the lionfish is devastating reef fish populations along the Florida coast and into the Caribbean. Now, an increasing number of environmentalists, consumer groups and scientists are seriously testing a novel solution to control it and other aquatic invasive species — one that would also takes pressure off depleted ocean fish stocks: they want Americans to step up to their plates and start eating invasive critters in large numbers.
“Humans are the most ubiquitous predators on earth,” said Philip Kramer, director of the Caribbean program for the Nature Conservancy. “Instead of eating something like shark fin soup, why not eat a species that is causing harm, and with your meal make a positive contribution?”….
…Scientists emphasize that human consumption is only part of what is needed to control invasive species and restore native fish populations, and that a comprehensive plan must include restoring fish predators to depleted habitats and erecting physical barriers to prevent further dissemination of the invaders….

2011 June 20. World's oceans in 'shocking' decline. By Richard Black, BBC News. Excerpt: The oceans are in a worse state than previously suspected, according to an expert panel of scientists.
In a new report, they warn that ocean life is "at high risk of entering a phase of extinction of marine species unprecedented in human history".
They conclude that issues such as over-fishing, pollution and climate change are acting together in ways that have not previously been recognized….
…The panel was convened by the International Programme on the State of the Ocean (IPSO), and brought together experts from different disciplines, including coral reef ecologists, toxicologists, and fisheries scientists….

2011 June 20. Is It Too Late for the Damba? By John S. Sparks and Christopher B. Braun, The NY Times. Excerpt: [Narrative of an ichthyologist working in Madagascar]…The native Paretroplus are striking fish, deep bodied forms that bear a close resemblance to their closest relatives on the Indian subcontinent, the genus Etroplus, despite being isolated since the Late Cretaceous period. There are less than 15 species of Paretroplus, and all but two are restricted to northwestern Madagascar. It is no exaggeration to state that a majority of these 15 species have some of the most restricted ranges of any vertebrates, frequently comprising only a short stretch of river or single small lake. Only Paretroplus polyactis has a widespread distribution along the eastern coast. Regrettably, most species of damba are on the verge of extinction, perhaps as a result of this strict endemism….
…For every endemic fish collected, huge stringers of introduced tilapia are captured. We have to leave this once diverse river and wonder if the damba are going to suffer the same fate as other Malagasy endemics….

2011 May 25. New View of Undersea Giant Kelp Forest "Canopy"--From Satellites Above. By Cheryl Dybas, National Science Foundation. Excerpt: …In a melding of data from the beneath the waves and from the skies above, researchers have developed a method for studying how environmental factors affect the kelp forests.
The results have allowed scientists to look at changes in giant kelp across hundreds of square miles in California's Santa Barbara Channel over 25 years, from 1984 through 2009….

2011 May 7. Man-made rock reef is part of a welcome seaweed change. By Tony Barboza, Los Angeles Times. Excerpt: …It was a gamble when Southern California Edison crews pushed basketball-size chunks of rock from a barge off San Clemente three years ago.
Eventually, the utility company hoped, the artificial reef it had assembled 50 feet below the waves would support a new kelp forest and fulfill state-imposed requirements to offset the damage its nearby nuclear power plant causes to marine life....
…Now, giant kelp has bounced back in the last few years, not because of made-man reefs but largely in response to a series of mild summers and an influx of cool, nutrient-rich water….

2010 October 16. From Beautiful Nudibranchs to Coral Graveyards: Marine Research in the Indian and Pacific Oceans. By Dr. Terry Goslinger, Climate Storytellers. Excerpt: ...For almost three decades I’ve been studying nudibranchs in the tropical Indian and Pacific Oceans. Nudibranchs are beautiful and brightly colored sea slugs that thrive on healthy coral reefs. While that has been exhilarating, it is the changes that I’ve seen on these reefs that make me sit upright in bed in the middle of the night. Climate change is seriously endangering these richest reservoirs of marine biodiversity....

2010 October 14. Caribbean Coral Die-Off Could Be Worst Ever. by Eli Kintisch, ScienceNow. Excerpt: Scientists studying Caribbean reefs say that 2010 may be the worst year ever for coral death there. Abnormally warm water since June appears to have dealt a blow to shallow and deep-sea corals that is likely to top the devastation of 2005, when 80% of corals were bleached and as many as 40% died in areas on the eastern side of the Caribbean.

2010 September 4. Taming the Wild Tuna. By Paul Greenburg, The New York Times. Excerpt: ...Researchers at a European Union-financed program, Selfdott, said they had succeeded in spawning the Atlantic bluefin in captivity without hormonal intervention.
If they can solve the problem of raising the offspring to adulthood — a challenging prospect — the bluefin may soon join Atlantic salmon, rainbow trout, branzino, yellowtail, turbot, shrimp, catfish and tilapia as an industrially farmed staple of the modern fish market. Which brings up an interesting question: Can a farmed version of bluefin tuna be better for the earth — and the species?
...Seafood today is roughly where landfood was 10,000 odd years ago. Just as Neolithic humans launched a domestication project after the last Ice Age and eventually replaced many wild mammal populations with tame ones, so, too, are modern humans parsing and domesticating the ocean, fish by fish.
Cultivating Atlantic bluefin tuna, environmentalists argue, could be even more harmful to the ocean than salmon farming. Atlantic bluefin are already ranched in great numbers — taken from the wild and fattened in net pens with wild forage fish like herring and sardines. ...The effect on forage fish, the foundation of the oceanic food chain, could be devastating. A worldwide overharvest of forage fish could damage not just bluefin tuna populations but other important commercial species that also rely on these fish for sustenance.
...If Atlantic bluefin is not farmed, it will most likely become an even more scarce luxury item. Global fishing moratoriums on the species have been proposed (and then rejected by the many nations that catch bluefin).

2010 June. Under the Water -- Diving to see the Disaster. ABC News video with Philippe Cousteau Jr. (grandson of Jacques Cousteau) showing underwater views of the Gulf of Mexico oil spill.

2010 June 1. Deep Underwater, Oil Threatens Reefs. By John Collins Rudolf, NY Times. Excerpt: …“We flipped on the lights, and there was one of the largest coral reefs in the Gulf of Mexico sitting right in front of us,” said Erik Cordes, a marine biologist at Temple University and chief scientist on the vessel, the Ronald H. Brown.
...Nine months later, the warm thrill of discovery has cooled into dread. The reef lies just 20 miles northeast of BP’s blown-out well, making it one of at least three extensive deepwater reefs lying directly beneath the oil slick in the gulf.
...Studies on the effects of oil and chemicals on coral are limited to the shallow-water variety, however. Essentially no research has been conducted on their slow-growing deepwater cousins. So BP’s spill has prompted scientists to embark on a sudden crash course on the interaction of deep-sea biology with these toxins.
…“It might be locally catastrophic, particularly if there’s an oxygen-depleted mass that develops,” said Jeffrey Short, Pacific science director for Oceana, a conservation group, and a former research chemist with the National Oceanic and Atmospheric Administration specializing in oil pollution.

2010 May 18. Gulf Oil Again Imperils Sea Turtle. By Leslie Kaufman, The NY Times. Excerpt: …Now Thelma and others of her species are being monitored closely by worried scientists as another major oil disaster threatens their habitat. Federal officials said Tuesday that since April 30, 10 days after the accident on the Deepwater Horizon, they have recorded 156 sea turtle deaths; most of the turtles were Kemp’s ridleys. And though they cannot say for sure that the oil was responsible, the number is far higher than usual for this time of year, the officials said.

…The turtles may be more vulnerable than any other large marine animals to the oil spreading through the gulf. An ancient creature driven by instinct, it forages for food along the coast from Louisiana to Florida, in the path of the slick.

…Then came the blowout on the Ixtoc 1. The deepwater well dumped three million barrels of crude into the gulf, covering the beach at Rancho Nuevo. Nine thousand hatchlings had to be airlifted to nearby beaches. Although the role of the oil in killing the turtles was never confirmed, by 1985, there were fewer than 1,000 Kemp’s ridleys left.

2010 Feb 18. A Battle at Midway. By Greg Boustead, SEED Magazine. Excerpt: What happened to that disposable Solo cup—the one you used once at a work party—after you tossed it into the garbage? For that matter, what happens to any of the countless plastic products (shopping bags, coffee stirrers, water bottles, etc.) we use and then discard on a daily basis? Of course, conventional plastic doesn’t readily biodegrade; so where is it now? If you live in North America or Asia, there’s a chance that cup is trapped in a broad ocean current, known as a gyre, in the middle of the northern Pacific Ocean along with an untold number of other pieces of litter in what has been named the Great Pacific Garbage Patch.
...Chris Jordan, a photographer whose work on visualizing impossibly large numbers we featured last week, traveled to the Midway Islands last year to document the Garbage Patch. What he returned with is visually shocking: a series of ghastly images of Albatross carcasses bursting with wholly undigested bits of plastic waste. The photographs quickly spread throughout the internet, bringing worldwide awareness to the potential threats of treating the ocean as a garbage disposal. Seed’s Greg Boustead recently caught up with the artist-cum-activist to talk about his trip, the art of capturing a nigh-invisible phenomenon, and what his pictures of grotesque, plastic-filled carcasses tell us....

2009 Nov 9. Afloat in the Ocean, Expanding Islands of Trash. By Lindsey Hoshaw, NY Times. Excerpt: ...Light bulbs, bottle caps, toothbrushes, Popsicle sticks and tiny pieces of plastic, each the size of a grain of rice, inhabit the Pacific garbage patch, an area of widely dispersed trash that doubles in size every decade and is now believed to be roughly twice the size of Texas. But one research organization estimates that the garbage now actually pervades the Pacific, though most of it is caught in what oceanographers call a gyre like this one — an area of heavy currents and slack winds that keep the trash swirling in a giant whirlpool.
Scientists say the garbage patch is just one of five that may be caught in giant gyres scattered around the world’s oceans. Abandoned fishing gear like buoys, fishing line and nets account for some of the waste, but other items come from land after washing into storm drains and out to sea.
Plastic is the most common refuse in the patch because it is lightweight, durable and an omnipresent, disposable product in both advanced and developing societies. It can float along for hundreds of miles before being caught in a gyre and then, over time, breaking down.
But once it does split into pieces, the fragments look like confetti in the water. Millions, billions, trillions and more of these particles are floating in the world's trash-filled gyres....

2009 October 29. Dining Out In An Ocean Of Plastic: How Foraging Albatrosses Put Plastic On The Menu. ScienceDaily. Excerpt: The North Pacific Ocean is now commonly referred to as the world's largest garbage dump with an area the size of the continental United States covered in plastic debris. The highly mobile Laysan albatross (Phoebastria immutabilis), which forages throughout the North Pacific, is quickly becoming the poster child for the effects of plastic ingestion on marine animals due to their tendency to ingest large amounts of plastic.
...Dr. Lindsay Young of the University of Hawaii and her colleagues examined whether Laysan albatrosses nesting on Kure Atoll and Oahu, Hawaii, 2,150 km away, ingested different amounts of plastic by putting miniaturized tracking devices on birds to follow them at sea and examining their regurgitated stomach contents. Surprisingly, birds from Kure Atoll ingested almost ten times the amount of plastic compared to birds from Oahu.
...The most common identifiable items they found were paraphernalia from the fishing industry such as line, light sticks, oyster spacers, and lighters....Unfortunately, while the albatross examined in this study were able to purge themselves of the plastic by regurgitating it, thousands of albatross die each year as a result of ingesting plastic debris. Plastic ingestion leads to blockage of the digestive tract, reduced food consumption, satiation of hunger, and potential exposure to toxic compounds to name but a few of its detrimental effects....

2009 October 8. NSF Releases Online Multimedia Package on Marine "Dead Zones". NSF Release 09-192. Excerpt: The Earth currently has more than 400 so-called "dead zones"--expanses of oxygen-starved ocean covering hundreds, or even thousands, of square miles that become virtually devoid of animal life during the summer; the worldwide count of dead zones is doubling every decade.
Most dead zones, such as the Gulf of Mexico's notorious dead zone, are caused by pollution that is dumped into oceans by rivers. But every summer since 2002, the Pacific Northwest's coastal waters--one of the--one of the U.S.'s most important fisheries--has been invaded by massive dead zones that are believed to be caused by an entirely different and surprising phenomena: changes in oceanic and atmospheric circulation that may, in turn, be caused by climate change....

2009 June 18. Mekong dolphins 'almost extinct'. BBC News. Excerpt: Pollution in the Mekong river has pushed freshwater dolphins in Cambodia and Laos to the brink of extinction, the conservation group WWF has said. Only 64 to 76 Irrawaddy dolphins remain in the Mekong, it says, and calls for a cross-border plan to help the dolphins.
Toxic levels of pesticides, mercury and other pollutants have been found in more than 50 calves that have died since 2003.
..."These pollutants are widely distributed in the environment and so the source of this pollution may involve several countries through which the Mekong river flows," said WWF veterinary surgeon Verne Dove in a press statement.
..."Necropsy analysis identified a bacterial disease as the cause of the calf deaths," Dr Dove said in the WWF report. "This disease would not be fatal unless the dolphin's immune systems were suppressed, as they were in these cases, by environmental contaminants," he said.
Researchers found toxic levels of pesticides such as DDT and environmental contaminants such as PCBs during analysis of the dead dolphin calves. These pollutants may also pose a health risk to human populations living along the Mekong - who consume the same fish and water as the dolphins - the group suggested.
High levels of mercury were also found in some of the dead dolphins, which directly affects the immune system making the animals more susceptible to infectious disease....

2009 April 14. Coral Transplant Surgery Prescribed for Japan. By Martin Fackler, The NY Times. Excerpt: SEKISEI LAGOON, Japan — Beneath the waves of this sapphire-blue corner of the East China Sea, a team of divers was busily at work.
Hovering along the steep, bony face of a dying coral reef, some divers bored holes into the hard surface with compressed-air drills that released plumes of glittering bubbles. Others followed, gently inserting small ceramic discs into the fresh openings.
Each disc carried a tiny sliver of hope for the reef, in the shape of fingertip-size sprigs of brightly colored, fledgling coral.
This undersea work site...is part of a government-led effort to save Japan’s largest coral reef, near the southern end of the Okinawa chain of islands. True to form in Japan, the project involves new technology, painstaking attention to detail and a generous dose of taxpayer money.
The project has drawn national attention, coming after alarming reports in the last decade that up to 90 percent of the coral that surrounds many of Okinawa’s islands has died off....
...“We have been replanting forests for 4,000 years, but we are only just now learning how to revive a coral reef,” said Mineo Okamoto, a marine biologist at Tokyo University of Marine Science and Technology, who has led development of the palm-size ceramic discs. “We finally have the technology.”
Critics, however, say the project might be wasted effort. They say transplanting is futile without addressing the problems that caused the reefs to deteriorate in the first place, like coastal redevelopment and chemical runoff from terrestrial agriculture. There is also the bigger problem of rising ocean water temperatures, for which there may be no easy fix....

2009 March 16. Leatherback Turtle Threatened By Plastic Garbage In Ocean. ScienceDaily. Excerpt: ...They're descendants of one of the oldest family trees in history, spanning 100 million years. But today leatherback turtles, the most widely distributed reptiles on Earth, are threatened with extinction themselves...
We've seen reference to the dangers plastic poses to marine life..., but how clearly have we received the message? Not well enough according to a recent article in the journal Marine Pollution Bulletin co-authored by Dalhousie University's Mike James.
“We wanted to see if plastics ingestion in leatherbacks was hype or reality,” says Dr. James, senior species at risk biologist for Fisheries and Oceans Canada and adjunct professor with Dalhousie’s Department of Biology.
“It was a monumental effort that looked back at necropsies over the last century from all over the world,” he explains. (Necropsies are post-mortem examinations performed on animals.) “After reviewing the results of 371 necropsies since 1968, we discovered over one third of the turtles had ingested plastic.”
...Once leatherbacks ingest plastic, thousands of spines lining the throat and esophagus make it nearly impossible to regurgitate. The plastic can lead to partial or even complete obstruction of the gastrointestinal tract, resulting in decreased digestive efficiency, energetic and reproductive costs and, for some, starvation.
...“The frustrating, yet hopeful aspect is that humans can easily begin addressing the solution, without major lifestyle changes,” says Dr. James. “It's as simple as reducing packaging and moving towards alternative, biodegradable materials and recycling.”...

2009 March 8. Proof on the Half Shell: A More Acidic Ocean Corrodes Sea Life. By David Biello, Scientific American.Excerpt: The shells of tiny ocean animals known as foraminifera—specifically Globigerina bulloides—are shrinking as a result of the slowly acidifying waters of the Southern Ocean near Antarctica. The reason behind the rising acidity: Higher carbon dioxide (CO2) levels in the atmosphere, making these shells more proof that climate change is making life tougher for the seas' shell-builders.
...The researchers found that modern G. bulloides could not build shells as large as the ones their ancestors formed as recently as century ago. In fact, modern shells were 35 percent smaller than in the relatively recent past—an average of 17.4 micrograms compared with 26.8 micrograms before industrialization. (One microgram is one millionth of a gram; there are 28.3 grams in an ounce.)
"We don't yet know what impact this will have on the organisms' health or survival," [says study co-author William Howard, a marine geologist at ACE], but one thing seems clear: the tiny animals won't be storing as much CO2 in their shells in the form of carbonate. "If the shell-making is reduced, the storage of carbon in the ocean might be, as well."
That's bad news for the climate, because the ocean is responsible for absorbing at least one quarter of the CO2 that humans load into the air through fossil fuel burning and other activities—and it is the action of foraminifera and other tiny shell-building animals, along with plants like algae that lock it away safely for millennia....

2009 January 19. Growing Taste for Reef Fish Sends Their Numbers Sinking. By Jennifer Pinkowski, The New York Times. Excerpt: ...The fierce appetite for live reef fish across Southeast Asia — and increasingly in mainland China — is devastating populations in the Coral Triangle, a protected marine region home to the world’s richest ocean diversity, according to a recent report in the scientific journal Conservation Biology. Spawning of reef fish in this area, which supports 75 percent of all known coral species in the world, has declined 79 percent over the past 5 to 20 years, depending on location, according to the report.
Overfishing in general, and particularly of spawning aggregations that occur when certain species of reef fish gather in one place in great numbers to reproduce, may be the culprit, says Yvonne Sadovy, a biologist at the University of Hong Kong who wrote the report along with scientists from Australia, Hong Kong, Palau and the United States.
...Since the 1980s, Hong Kong has been the epicenter of the live fish trade. That trade has greatly expanded in the last decade to an $810 million business, according to the Worldwide Fund for Nature, which monitors the market. Rising wealth in mainland China may be a contributing factor to the increase in the trade with the demand for exotic fish especially high in Shanghai and Beijing. Destinations popular with Chinese tourists are seeing an increase, too....
...Even locals unaffiliated with the tourist trade are aware of the surge. Across the street from the Port View, Malays at the famous Night Market speak with awe about the Chinese tourists who spend “a thousand ringgits a week just eating fish.”That’s about $280....

2008 December 10. 1 / 5 of Coral Reefs Already Lost, Much More Feared. The New York Times. Excerpt: POZNAN, Poland (AP) -- The world has lost nearly one-fifth of its coral reefs and much of the rest could be destroyed by increasingly acidic seas if climate change continues unchecked, an environmental group warned Wednesday.
Global warming and the rising temperature of the oceans are the latest and most serious threats to coral, already damaged by destructive fishing methods and pollution, the International Union for Conservation of Nature said.
''The world has lost about 19 percent of its coral reefs during the last 20 years,'' said IUCN's director general, Julia Marton-Lefevre...
''If current trends in carbon dioxide emission continue, many of the remaining reefs will be lost in the next 20 to 40 years,'' she told reporters....
Increasing carbon dioxide levels in the atmosphere, which fuels global warming, is raising the level as well as the temperature of the oceans, said Olof Linden of the World Maritime University in Malmo, Sweden. That makes the water more acidic, adversely affecting reef-building coral that rely on calcification to build their shells....

2008 August 3. Stinging Tentacles Offer Hint of Oceans’ Decline. By ELISABETH ROSENTHAL, The New York Times. Excerpt: BARCELONA, Spain — Blue patrol boats crisscross the swimming areas of beaches here with their huge nets skimming the water’s surface. The yellow flags that urge caution and the red flags that prohibit swimming because of risky currents are sometimes topped now with blue ones warning of a new danger: swarms of jellyfish.
In a period of hours during a day a couple of weeks ago, 300 people on Barcelona’s bustling beaches were treated for stings, and 11 were taken to hospitals.
From Spain to New York, to Australia, Japan and Hawaii, jellyfish are becoming more numerous and more widespread, and they are showing up in places where they have rarely been seen before, scientists say....
But while jellyfish invasions are a nuisance to tourists and a hardship to fishermen, for scientists they are a source of more profound alarm, a signal of the declining health of the world’s oceans.
...The explosion of jellyfish populations, scientists say, reflects a combination of severe overfishing of natural predators, like tuna, sharks and swordfish; rising sea temperatures caused in part by global warming; and pollution that has depleted oxygen levels in coastal shallows....

2008 July 8. Corals, Already in Danger, Are Facing New Threat From Farmed Algae. By CHRISTOPHER PALA, The New York Times. Excerpt: BUTARITARI, Kiribati — Off the palm-fringed white beach of this remote Pacific atoll, the view underwater is downright scary.
Corals are being covered and smothered to death by a bushy seaweed that is so tough even algae-grazing fish avoid it. It settles in the reef’s crevices that fish once called home, driving them away.
Dead coral stops supporting the ecosystem and, within a couple of decades, it will crumble into rubble, allowing big ocean waves to reach the beach during storms and destroy the flimsy thatched huts of the Micronesians.
“We are catching less and less fish, and the seaweeds are fouling our nets,” says Henry Totie, a fisherman and Butaritari’s traditional chief, in an interview in his traditionally built house in the village near the blue-green lagoon.
“This is one of the most damaging seaweeds I have ever seen,” says Jennifer E. Smith of the National Center for Ecological Analysis and Synthesis at the University of California, Santa Barbara, who has studied the Hawaiian invasion for eight years...
Moiwa Erutarem, the Butaritari representative of the fisheries ministry, said the biggest losses were being felt by the most vulnerable: those who use nets in the shallow coral table and do not have the boats required to fish farther away. Seafood is virtually the only source of protein in Butaritari, complemented by breadfruit and coconut.
This equatorial island of 4,000 people is the latest victim of a 30-year global effort to encourage poor people in the coastal areas of the tropics to grow seaweed that, while not edible, produces carrageenan, an increasingly sought-after binder and fat substitute used in the food industry, notably in ice cream.

2008 June 10. Tallying the Toll on an Elder of the Sea. By NATALIE ANGIER, The New York Times. Excerpt: MILFORD, Conn. - Horseshoe crabs may look ancient and alien and battery-operated, they may look like Wilma Flintstone's idea of a Roomba vacuum cleaner, yet to the sixth-grade students from Columbus School in nearby Bridgeport, the most outrageous thing about the bronze-helmeted creatures crawling clumsily along the beach was not their appearance but their size - or rather sizes.
One boy pointed to a linked pair of horseshoe crabs, a relatively compact specimen maybe seven inches across clinging to the tail end of a much larger companion. A kid crab hitching a ride on its mother? No, explained Jennifer H. Mattei, head of the biology department at Sacred Heart University in Fairfield, who led the expedition. They were both full-grown, a male and a female, and the female was the bruiser out front.
Among horseshoe crabs, Dr. Mattei explained, adult females are a good 25 to 30 percent bigger than their mates, a fact that the girls greeted with hoots of triumph, boys of indignation. Why are the females bigger? a boy demanded. It's supposed to be the other way around!
As it turned out, the answer to that question was closely tied to the reason the students from Cheryl Crevier's class had ventured out on a flawless June morning to the shores of Long Island Sound. With clipboards purposefully in hand and tape measures jauntily around neck, the 22 children were there to help catch, measure and tag as many specimens as they could find of the American horseshoe crab, or Limulus polyphemus, one of the oldest and most tenacious species on Earth. Fossils found this year in Manitoba reveal that the animal's architecture has hardly changed in 445 million years.
The student project is part of a major effort now under way from Maine to Florida...(www.projectlimulus.org). Experts are desperate to know whether their suspicions are correct - that as a result of being harvested en masse for use as fishing bait, horseshoe crab populations are beginning to crash.
The loss of the horseshoe crab would be tragic, researchers said, not only because the creatures are fascinating and cute and predate the dinosaurs by 200 million years, but also because so many contemporary life forms depend on them. Their annual spawns draw hundreds of species of migratory birds, predatory fish, reptiles, amphibians and various other alimentary canals eager to brunch on the freshly deposited Limulus eggs.
..."A single female horseshoe crab can put down 80,000 eggs a year, four million in her lifetime," said John T. Tanacredi, a professor of earth and marine sciences at Dowling College in Oakdale, N.Y....
In the last few years, the Asian market for North American eel and conch meat has soared, and it seems that gravid female horseshoe crabs make the best bait. Even the stalwart Limulus can't last if all its eggs end up in one basket - shaped like a fisherman's boat.

2008 Mar 4. Want to Save a Coral Reef? Bring Along Your Crochet Needles. By PATRICIA COHEN, The New York Times. The exotically shaped creatures that began to sprout silently all over the cozy lecture hall were soon spilling onto empty chairs and into women's laps and shopping bags. When fully grown, these curiously animate forms will find a home as part of a mammoth version of the Great Barrier Reef. But at the moment they were emerging at a remarkable pace from the rapidly flicking crochet hooks wielded by members of the audience.
...This environmental version of the AIDS quilt is meant to draw attention to how rising temperatures and pollution are destroying the reef, the world's largest natural wonder, said Margaret Wertheim, an organizer of the project, who was in Manhattan last weekend to lecture, offer crocheting workshops and gather recruits. The reef is scheduled to arrive in New York City next month.
As she explained to the 40 people, nearly all women, who had gathered at New York University on Saturday, "This has grown from something that was a little object on our coffee table" to an exhibition that, so far, spreads over 3,000 square feet. And that was before the addition of that day's catch.
...the Wertheims got the idea for the Hyperbolic Crochet Coral Reef. The Institute for the Humanities at New York University is co-sponsoring the exhibit, which will appear in the university's Broadway Windows at East 10th Street and at the World Financial Center April 5 through May 18.
In the university's auditorium Ms. Wertheim opened a large bag and began throwing out long snaking tubes, tightly scrunched blooms, fat textured spirals, and hairy coiled cactuses created out of yarn, thread, plastic bags, ties, can flip tops, videotape, ribbon, tinsel and more in a riotous splash of reds, blues, pinks, oranges, greens, tans, purples and yellows.
Later the group members traipsed upstairs to a large jewelry studio where they settled at one of six thick wooden worktables and began crocheting. The woven organisms developed so quickly it seemed as though time-lapse photography was at work....

2008 Feb 14. Map shows toll on world's oceans. By Helen Briggs, Science reporter, BBC News, Boston Excerpt: Only about 4% of the world's oceans remain undamaged by human activity, according to the first detailed global map of human impacts on the seas. A study in Science journal says climate change, fishing, pollution and other human factors have exacted a heavy toll on almost half of the marine waters. Only remote icy areas near the poles are relatively pristine, but they face threats as ice sheets melt, it warns.
The authors say the data is a "wake-up call" to policymakers. ...Lead scientist, Dr Benjamin Halpern, of the National Center for Ecological Analysis and Synthesis in Santa Barbara, US, said humans were having a major impact on the oceans and the marine ecosystems within them. "In the past, many studies have shown the impact of individual activities," he said. "But here for the first time we have produced a global map of all of these different activities layered on top of each other so that we can get this big picture of the overall impact that humans are having rather than just single impacts."
...The researchers divided the world's oceans into 1km-square sections and examined all real data available on how humankind is influencing the marine environment. They then calculated "human impact scores" for each location, presenting this as a global map of the toll people have exacted on the seas. The scientists say they were shocked by the findings. "I think the big surprise from all of this was seeing what the complete coverage of human impacts was," said Dr Spalding, senior marine scientist for international conservation group The Nature Conservancy. "There's nowhere really that escaped. It's quite a shocking map to see." He said the two biggest drivers in destroying marine habitats were climate change and over-fishing....

This is narrowly true, in that food from a dirty kitchen is likely to be unsafe. But it’s also true in the broadest sense. A good example is the tuna in sushi. Many New Yorkers have come to love the convenience, taste and aesthetic appeal of sushi. But as The Times reported Wednesday after testing tuna from 20 Manhattan stores and restaurants, sushi made from bluefin tuna may contain unacceptable levels of mercury, which acts as a neurotoxin. Every piece of that tuna, glistening on its bed of rice, is a
report on the worrisome state of the oceans....

2008 January 11. Greenhouse ocean may downsize fish. [EurekAlert (11.1.08)] By 2100, warmer oceans with more carbon dioxide may no longer sustain 1 of the world's most productive fisheries, says USC marine ecologist. The last fish you ate probably came from the Bering Sea. But during this century, the sea's rich food web stretching from Alaska to Russia-could fray as algae adapt to greenhouse conditions. "All the fish that ends up in McDonald's, fish sandwiches-that's all Bering Sea fish," said USC marine ecologist Dave Hutchins, whose former student at the University of Delaware, Clinton Hare, led research published Dec. 20 in Marine Ecology Progress Series, a leading journal in the field. At present, the Bering Sea provides roughly half the fish caught in U.S. waters each year and nearly a third caught worldwide. "The experiments we did up there definitely suggest that the changing ecosystem may support less of what we're harvesting things like pollock and hake," Hutchins said.

2008 January 3. Federal Judge Orders Navy To Adopt Significant Mitigation Measures For Sonar Use. District Court Establishes Protections For
Marine Mammals During Exercises. Excerpt: LOS ANGELES - The U.S. District Court for the Central District of California issued today a preliminary injunction requiring a series of mitigation measures that will govern the use of mid-frequency (MFA) sonar by the U.S. Navy during training exercises in the rich biological waters off Southern California. In its order, the Court considered both the environmental benefits of mitigation and the feasibility of specific measures.
Calling key elements of the Navy's mitigation scheme "grossly inadequate to protect marine mammals from debilitating levels of sonar exposure," the court imposed ... additional limitations to protect marine mammals....
...."We have said from the beginning of this litigation
that the Navy can meet its training objectives while substantially increasing protections against unnecessary harm to whales and other marine mammals," said Joel Reynolds, director of the Marine Mammal Protection Project at the Natural Resources Defense Council (NRDC), which filed the lawsuit. "We are very pleased that the Court has agreed with us and has enjoined the Navy from conducting these
exercises unless it takes the necessary precautions."
...The high-intensity MFA sonar system can blast vast areas of the oceans with dangerous levels of underwater noise and has killed marine mammals in numerous incidents around the world.

15 December 2007. In China, Farming Fish in Toxic Waters. By DAVID
BARBOZA, The New York Times. Excerpt: FUQING, China - Here in southern China, beneath the looming mountains of Fujian Province, lie dozens of enormous ponds filled with murky brown water and teeming with eels, shrimp and tilapia, much of it destined for markets in Japan and the West....Fuqing is No. 1 on a list for refused seafood shipments from China....the two most glaring environmental weaknesses in China: acute water shortages and water supplies contaminated by sewage, industrial waste and agricultural runoff that includes pesticides. The fish farms, in turn, are discharging wastewater that further pollutes the water supply.
"Our waters here are filthy," said Ye Chao, an eel and shrimp farmer who has 20 giant ponds in western Fuqing. "There are simply too many aquaculture farms in this area. They're all discharging water here, fouling up other farms." Farmers have coped with the toxic waters by mixing illegal veterinary drugs and pesticides into fish feed, which helps keep their stocks alive yet leaves poisonous and carcinogenic residues in seafood, posing health threats to consumers.
...No one is more vulnerable to these health risks than the Chinese, because most of the seafood in China stays at home. But foreign importers are also worried.
...China produces about 70 percent of the farmed fish in the world, harvested at thousands of giant factory-style farms that extend along the entire eastern seaboard of the country...."There are heavy metals, mercury and flame retardants in fish samples we've tested," said Ming Hung Wong, a professor of biology at Hong Kong Baptist University. "We've got to stop the pollutants entering the food system."
...More than half of the rivers in China are too polluted to serve as a source of drinking water....

11 December 2007. Experts Study Lake Champlain Eel Decline. (AP) Excerpt: Scientists are trying to determine what caused Lake Champlain's populations of American eels to decline to almost nothing over the last two decades. ..Until the early 1980s ...commercial anglers would harvest tons of them every year. "We have a fairly large vertebrate that has gone from abundant to virtually absent in 20 years," said Tom Berry, Lake Champlain program director for the Nature Conservancy. ...By the early 1990s Quebec banned the commercial fishing of eels. American eels start life in the Sargasso Sea, an area in the Atlantic Ocean between the West Indies and the Azores. After hatching, eel larvae float on ocean currents to East Coast rivers, including the St. Lawrence. Historically, immature female eels swam up the St. Lawrence and Richelieu rivers and lived 10 to 20 years in Lake Champlain before returning to the Sargasso Sea. "It is just remarkable they travel 3,000 miles when they are only an inch long. It boggles the mind," said UVM fisheries biologist Ellen Marsden.
Biologists do not fully understand the reason for the decline.
Theories include climate change, pollution, and overfishing of young eels. But the decline could also be due to the reconstruction in the 1960s of two hydroelectric dams on the Richelieu River in Quebec. The dams could have prevented the eels from reaching Lake Champlain. A decade ago, Hydro-Quebec installed an eel ladder at one of the dams. "Within 10 days we measured eels going up the ladder," said
Quebec fisheries biologist Pierre Dumont....

1 May 2007. Coral Is Dying. Can It Be Reborn? By CORNELIA DEAN, NY Times. TAVERNIER, Fla. - ... Meaghan Johnson ..., a program coordinator for the Nature Conservancy, ...Ken Nedimyer, ...and Philip Kramer, who directs the conservancy's Caribbean Marine Program, ...had come to see... an array of concrete disks set in the sand. Each one held a tiny piece of coral. Mr. Nedimyer had led them to a nursery, one of a number he has established since 2000, .... He is working with assistance from the conservancy, which in turn cooperates with the Florida Keys National Marine Sanctuary and the National Oceanic and Atmospheric Administration, which has its own coral efforts in places like Puerto Rico. Meanwhile, the Environmental Protection Agency is looking at water quality standards for corals in Florida, Hawaii, the Virgin Islands, American Samoa and Puerto Rico, .... The Coral Reef Task Force, created in the Clinton administration, regularly assesses coral health. ... Many would say corals globally are already so damaged, and so threatened by further environmental degradation, that there is little chance restoration efforts can turn things around. Staghorn and elkhorn corals, Mr. Nedimyer's principal interests, were once abundant in South Florida, the Bahamas and elsewhere in the Caribbean. But since the 1990s they have significantly declined, to the point that last year they were placed on the threatened list, under the Endangered Species Act...."We have lost 25 percent of the world's corals in the last 25 years," David E. Vaughan, director of the Center for Coral Reef Research at Mote, said in an interview, adding that 25 percent more are expected to die in the next decade or two. "Sometimes we sound like doomsday sayers," Dr. Vaughan said, "but those are the facts." ...Corals in South Florida have another big problem, a die-off of sea urchins, which began succumbing wholesale to a mysterious ailment about 20 years ago. Urchins graze on unwanted algae, and without them, corals in many areas have been smothered in overgrowth, making it difficult or impossible for them to grow or propagate.

17 April 2007. No-Fishing Zones in Tropics Yield Fast Payoffs for Reefs. By CHRISTOPHER PALA. NY Times. Excerpt: NGIWAL, Palau - ...on Palau's main island of Babeldaob, Islias Yano, 57, ..."We fished certain fish in certain seasons," he recalled. "Each reef could only be fished by people from a certain village." Village elders would rotate fishing on reefs, he recounted, to husband their slow-growing main source of food. Starting in the 1980s, population growth, new seafood markets in Asia and modern ways of thinking washed away the elders' authority and rules. "Outsiders started coming into our reefs, they used scuba gear and dynamite, and the fish got smaller and fewer," Mr. Yano said, shaking his head. ... In Ngiwal, the reaction was not long in coming. Once again, the elders ruled. In 1994, they banned fishing in a small area of reef that was partly accessible on foot. The village women, who traditionally gather shellfish at low tide, noticed how the fish became more plentiful there in a few years. The reef became locally famous, and other villages started to do the same. Today, Palau, a tiny island state 600 miles east of the Philippines that is internationally known as a site for recreational diving, is at the forefront of a worldwide movement to ban fishing in key reefs to allow the return of prized species. It now protects a patchwork of reefs and lagoon waters amounting to 460 square miles. ...That Palau has taken the lead in ocean conservation is no accident. Even among Pacific peoples, Palauans have been known for prizing fish and seafood over meat and farmed vegetables, and its fishermen have stood out for their keen understanding of the reefs. ...

4 April 2007. Quake lifts Solomons island out of the sea. By Neil Sands. Excerpt: RANONGGA, Solomon Islands (AFP) - The seismic jolt that unleashed the deadly Solomons tsunami this week lifted an entire island metres out of the sea, destroying some of the world's most pristine coral reefs. In an instant, the grinding of the Earth's tectonic plates in the
8.0magnitude earthquake Monday forced the island of Ranongga up three metres (10 foot). Submerged reefs that once attracted scuba divers from around the globe lie exposed and dying after the quake raised the mountainous landmass, which is 32-kilometres (20-miles) long and 8-kilometres (5-miles) wide. ...The stench of rotting fish and other marine life stranded on the reefs when the seas receded is overwhelming and the once vibrant coral is dry and crunches underfoot. Dazed villagers stand on the shoreline, still coming to terms with the cataclysmic shift that changed the geography of their island forever, pushing the shoreline out to sea by up to 70 metres. ...fisherman Hendrik Kegala had just finished exploring the new underwater landscape of the island with a snorkel when contacted by the AFP team. He said a huge submerged chasm had opened up, running at least 500 metres (550 yards) parallel to the coast. On the beach at Niu Barae, the earthquake has revealed a sunken vessel that locals believe is a Japanese patrol boat, a remnant of the fierce fighting between Allied forces and the Japanese in WWII. ...Jackie Thomas, acting manager for Worldwide Fund for Nature (WWF) in the Solomons, said the loss of the reefs was a huge blow for the fishing communities that are dotted along Ranongga's coast. "The fish from the reefs are the major source of protein for the villagers," she told AFP from Gizo."....

27 February 2007. EU Wants to Speed Up Tuna Protection. By THE ASSOCIATED PRESS Excerpt: BRUSSELS, Belgium (AP) -- The European Union's top fisheries official on Tuesday pressed for stronger protections for the overfished bluefin tuna, an increasingly rare delicacy in high-end restaurants around the world. EU Fisheries Commissioner Joe Borg said he wants to extend the fishing offseason, reduce tuna sold on the black market, and impose new worldwide cuts in catch quotas as quickly as possible. The EU's 27 member states were expected to approve the measure within weeks, officials said. The proposal would reduce catch quotas this year for bluefin tuna caught in the eastern Atlantic and Mediterranean to 29,500 tons from 32,000 officials said....Globally two years ago, Atlantic bluefin tuna stocks have dropped by 80 percent over the past 30 years. The global tuna export market in 2002 was $5 billion, according to the U.N. Food and Agriculture Organization.

13 February 2007. GOLFO DE SANTA CLARA JOURNAL: Vaquita Porpoise, and a Way of Life, Face Extinction. By JAMES C. McKINLEY Jr., The New York Times. Excerpt: Fishermen in Golfo de Santa Clara say their catches of shrimp and fish have steadily declined over the years. GOLFO DE SANTA CLARA, Mexico - ...The Mexican government set up a reserve in 1993 to protect the vaquita porpoises, which become entangled in fishing nets and drown. But the area is too small, with fishing banned in only about 637 square miles. Environmentalists from the United States and Mexico had begged the fishermen to stop using the gill nets that are killing off La Vaquita, or the little cow, a porpoise that now has the dubious distinction of being one of the most endangered marine mammals in the world. Only about 400 of them survive in the waters at the tip of the Gulf of California where the Colorado River once poured into the sea, environmentalists say, and the only way to save them is to ban commercial fishing with nets in about 1,545 square miles.... Environmentalists have put forward proposals to pay the fishermen not to fish and to develop tourism as an alternative source of income. But the men with rope-hardened hands and weathered faces are skeptical. ..."They want us to stop fishing," said Andres Gonzalez, a 43-year-old fisherman. "They want to take care of the animals here, but they are not taking care of the people." ...biologists say studies of the carcasses of the vaquita porpoises show no signs of malnourishment, but plenty of scars from fishing nets. The advocates of buying out the fishermen note that the human population at the gulf's tip is quite small, about 50,000 people in three towns, including maybe 10,000 fishermen. The solution, they say, is to ban fishing with nets in the upper gulf and establish a $50 million trust fund and use the earnings to pay fishermen a total of about $4 million a year, not to fish but to pursue other trades. The program would last at least seven years, until the porpoise population could recover....

17 December 2006. 20 Million Years and a Farewell. By ANDREW C. REVKIN, NY Times. Excerpt: The first species to be erased from this planet's great and ancient Order of Cetaceans in modern times is not one of the charismatic sea mammals that have long been the focus of conservation campaigns, like the sperm whale or bottlenose dolphin. It appears to be the baiji, a white, nearly blind denizen of the Yangtze River in China. On Wednesday, an expedition in search of any baiji, run by Chinese biologists and baiji.org, a Swiss foundation, ended empty-handed after six weeks of patrolling its onetime waters in the middle and lower stretches of the river, the baiji's only known habitat. The Yangtze, Asia's longest waterway and thought to be akin to the Amazon long ago in its biological richness, now has a dominant species: the 400 million (and counting) people busily plying its waters and industrializing its banks. For some 20 million years, the baiji, also called the white-flag dolphin, frequented the Yangtze's sandy shallows, using sonar to catch fish in the silty flow. In the last few decades, the dolphin's numbers plunged as rapidly as the Chinese economy surged. The Yangtze's sandy shallows, which the baiji frequented, have largely been dredged for shipping. The baiji sought fish that have been netted or driven from the river by pollution. And its sonar may have been disrupted by the propeller noise from boats above. A 1997 survey counted 13 baiji in the river. None of the dolphins survive in captivity......

3 November 2006. Study Sees 'Global Collapse' of Fish Species. By CORNELIA DEAN, NY Times. Excerpt: If fishing around the world continues at its present pace, more and more species will vanish, marine ecosystems will unravel and there will be "global collapse" of all species currently fished, possibly as soon as midcentury, fisheries experts and ecologists are predicting. The scientists, who report their findings today in the journal Science, say it is not too late to turn the situation around. As long as marine ecosystems are still biologically diverse, they can recover quickly once overfishing and other threats are reduced, the researchers say. But improvements must come quickly, said Boris Worm of Dalhousie University in Nova Scotia, who led the work. Otherwise, he said, "we are seeing the bottom of the barrel." ...Twelve scientists from the United States, Canada, Sweden and Panama contributed to the work reported in Science today. "We extracted all data on fish and invertebrate catches from 1950 to 2003 within all 64 large marine ecosystems worldwide," they wrote. "Collectively, these areas produced 83 percent of global fisheries yields over the past 50 years." ...The researchers found that 29 percent of species had been fished so heavily or were so affected by pollution or habitat loss that they were down to 10 percent of previous levels, their definition of "collapse." ...Dr. Worm said ... he...extrapolated the data into the future "to see where it ends at 100 percent collapse, you arrive at 2048."....

31 October 2006. Building Resilience May Help Corals, Mangroves Survive. Excerpt: GENEVA, Switzerland, Environment News Service (ENS) - Survival strategies for coral reefs and mangroves threatened by climate change are outlined by scientists of IUCN-World Conservation Union and the Nature Conservancy in two new publications launched today. The strategies rely on managing stressors other than global warming so that corals and mangroves are more resilient and able to survive in a warming world. Climate change is destroying tropical marine ecosystems through sea temperature increase and ocean acidification. Scientists say 20 percent of the world's coral reefs have already been ruined and a further 50 percent are facing immediate or long term danger of collapse. Yet, one of the reports published today shows that saving the world's coral reefs may still be possible. By fighting other stress factors such as pollution or overfishing impacting coral reefs, the reefs will be able to better adapt to climate change impacts, according to the report, "Coral Reef Resilience and Resistance to Bleaching." ...Coral reefs only cover 0.2 percent of the ocean floor, but contain 25 percent of marine species globally. Coral reefs provide livelihoods to 100 million people and provide the basis for industries such as tourism and fishing, worth an annual net benefit of US$30 billion, the report states. One hectare of mangroves is estimated to deliver products and services worth up to $900,000. Examples of these products and services include timber and wood chips, an environment for fish spawning, and habitat for economically important species. ...View the publications online: "Coral Reef Resilience and Resistance to Bleaching," Gabriel D. Grimsditch and Rodney V. Salm and "Managing Mangroves for Resilience to Climate Change," Elizabeth Mcleod and Rodney V. Salm.

24 October 2006. The Biologist and the Sea: Lessons in Marine-Life Restoration. By ANDREW C. REVKIN. Excerpt: MONTAUK, N.Y. - For Carl Safina - a biologist, conservationist and prize-winning author - passions and intellectual pursuits are deeply entwined. Dr. Safina's doctoral thesis was on the interrelated behaviors and annual rhythms of the common tern and bluefish, which feast on the same bay anchovies and other small prey. On a recent three-hour fishing trip Dr. Safina reflected on two decades of work revealing the enormous disruption of ocean ecosystems by industrial-scale fishing and other human activities.  His prime goal, he has said, is to develop a "sea ethic" similar to the land ethic of Aldo Leopold, and a scattering of success stories has convinced him that a balance is still possible between exploitation and conservation of marine resources.
Dr. Safina: In general, I'm O.K. with using what's in the oceans. I just don't think we should be using it up. So the point to me is not necessarily to put things off limits, although some places probably should be off limits where fish spawn and places like that. But the main thing is to restore the abundance of what's in the ocean so that we can have a viable system where all these animals can live and eat each other, and then we can take a little bit.
Q. What most discourages you related to the trends you see in the oceans?
A. That it's so easy to see what we need to do, it's so easy to see how things can be so much better and yet it's taking so much time to come around to it.
Q. What are some of those improvements?
A. We need to just set fishing quotas and adhere to them, and make them realistic, and listen to what the scientists say about how many fish can come out of the ocean. And if we do that, we will get more of what we want.
Q. And what's one of the most encouraging things you've seen?
A. That fish are recoverable. Many of the fish that we have here were much less abundant 15 years ago than they are now. We did get some good regulations passed, and the fish began recovering right away. They know what to do. If you just don't kill them as fast, they start coming back. So the most encouraging thing is that it works, but a lot of that could be much more widespread throughout the country and the rest of the world.

28 September 2006. After a Seven-Year Ban, Salmon Fishing Returns to Maine. By PAM BELLUCK, The New York Times. Excerpt: EDDINGTON, Me. - Forget your trout, your striped bass. Wild Atlantic salmon are a fisherman's Holy Grail. For the first time since 1999, Maine salmon fishermen wait to try their luck in the Eddington Pool below the Veazie Dam on the Penobscot River. ... in 1999, Maine, the last American bastion of wild Atlantic salmon, closed its rivers to salmon fishing to save the salmon, whose numbers had shrunk from pollution, dams and other forces. ...Now, with salmon slowly returning, Maine has opened its first wild salmon season in seven years - a month of restricted fishing on the state's storied Penobscot River. ...Maine is starting with baby steps: fall fishing, when salmon are smaller; catch-and-release only; no barbs on fishhooks; and no fishing when the water temperature hits 70 degrees because hooked fish recover better in cooler water. Mr. Keliher said each salmon reaching the Veazie Dam, where they are temporarily trapped, will be checked to see if it was hooked and what condition it is in. If the fish seem to withstand the fall season, Maine may allow the more-popular spring fishing. The restrictions satisfied most environmentalists, said Andrew Goode, board president of the Penobscot River Restoration Project, the coalition buying the dams....

September 2006. "Super Sucker" keeping coral reefs health. Nature Conservancy. Marine researchers in Hawaii have a new weapon in the battle against alien algae: an underwater vacuum cleaner affectionately named the Super Sucker. In initial tests, the machine in one hour removed up to 800 pounds of invasive algae, which smothers and kills coral. ...The new tool is one component of a larger strategy to combat non-native algae invasions, which dominate Kaneohe Bay and Oahu's south shore and are also abundant on the south shores of Maui and Molokai.

10 August 2006. Federal Action Helps Salmon Fishermen By THE ASSOCIATED PRESS. Excerpt: GRANTS PASS, Ore. (AP) - Commerce Secretary Carlos Gutierrez on Thursday declared commercial salmon fishing off Oregon and California a failure this year, after sharp harvest cutbacks imposed to protect the struggling return of salmon to the Klamath River. Under federal fisheries law, the formal declaration, the first since 1992 to come before the end of the fishing season, makes it possible for lawmakers from the two states to move forward in seeking up to $80 million in aid, an effort that has been stymied for lack of a declaration.

8 August 2006. Unlikely Partners Create Plan to Save Ocean Habitat Along With Fishing
By JON CHRISTENSEN. NY Times. Excerpt: MORRO BAY, Calif. - Fishery closings are generally not greeted as good news in ports like this.
Angry protests are more likely. So to find an environmentalist and two commercial fishermen quietly conspiring on the bridge of a fishing boat docked in Morro Bay as a far-reaching prohibition on bottom trawling went into effect on the West Coast this summer was unusual, to say the least.
The environmentalist, Chuck Cook, said he had been called a "conservation Nazi" in some ports. And Gordon Fox, who has been dragging fish and shrimp from the bottom of the Pacific Ocean for nearly 30 years, admitted the conversation would be "perceived by some in the industry to be sleeping with the enemy." Together with other fishermen and conservationists, Mr. Cook and Mr. Fox have fashioned a plan that they hope will preserve the fish and, just as important to both of them, fishing here off the central coast of California. It is a complicated deal centered on a simple quid pro quo, Mr. Cook said. The trawlers in Morro Bay agreed to join the Nature Conservancy and Environmental Defense, an organization that advocates market-based solutions, in proposing three "no-trawl zones." They would cover nearly 6,000 square miles of ocean between here and Monterey Bay, an area roughly the size of Connecticut. In exchange, the Nature Conservancy agreed to buy fishing permits and boats from fishermen, like Mr. Fox, who want to get out of the trawling business, trade their boats for smaller vessels, and try to find more selective, sustainable ways to continue fishing. ...The deal struck by conservationists and fishermen follows a chart laid out by the National Research Council in a 2002 report on the devastating effect of repeatedly dragging nets across seafloor habitat. "That's been our bible on this project," Mr. Cook said of his well-worn copy of the study, which surveyed years of research on trawling. Its recommendations included closing vulnerable areas of the ocean floor to bottom trawling and reducing fishing outside protected areas in tandem, rather than as separate strategies, as had been done in the past.

16 July 2006. Fishing Depletes Mediterranean Tuna, Conservationists Say. By ELISABETH ROSENTHAL. NY Times. Excerpt: SUCURAJ, Croatia - Two decades ago, the channels that separate the Adriatic Islands here were brimming with giant bluefin tuna, a species so plentiful that tourists used to climb ladders by the sea to watch the schools swim by.
Today, these majestic predators are rarely if ever caught. ...The tuna population in the Mediterranean is nearing extinction, a new World Wildlife Fund report concludes, with catches down 80 percent over the past few years, even for high-tech trawlers that now comb remote corners of the sea in search of the hard-to-find fish. ..."Significant negative changes" have occurred in the fish stocks of the Adriatic because of overfishing, said Dr. Nedo Vrgoc of the Institute of Oceanography and Fisheries in Split, Croatia, with a particularly steep reduction in long-lived fish species like rays, John Dory and anglerfish....

26 October 2005. Half of Coral Reefs Could Be Destroyed. Nearly half of the world's coral reefs may be lost in the next 40 years unless urgent measures are taken to protect them against the threat of climate change, according to a new report released Tuesday by the World Conservation Union. The Swiss-based organization called for the establishment of additional marine protected areas to prevent further degradation by making corals more robust and helping them resist bleaching...Coral bleaching is caused by increased surface temperatures in the high seas and higher levels of sunlight caused by climate change. As temperatures rise, the algae on which corals depend for food and color die out, causing the coral to whiten, or "bleach."

3 May 2005. Tracking the Imperiled Bluefin From Ocean to Sushi Platter. By ANDREW C. REVKIN. NY Times. For sushi aficionados, the essence of the Atlantic bluefin tuna is its fat-laced, butter-soft belly meat, called toro. For the long-liners, purse seiners, harpooners, trappers and fish farmers who seek the bluefin from Cape Hatteras to the frigid waters south of Iceland to the balmy Mediterranean, the fish are a potential bonanza, with choice specimens fetching $50,000 or more in Tokyo. But the intensifying trade in bluefin may soon empty the waters of this master of the sea. In just the last 35 years, exploding markets for sushi-grade tuna, combined with intensifying industrial-scale hunts aided by satellites and spotters in airplanes, have devastated not only the fish but also many fisheries. ...The threat to the bluefin was underscored last week by researchers who have tracked hundreds of the fish on their ocean-spanning journeys using electronic tags. They found that the tuna that spawn in the west, which are most severely depleted, are further threatened by an ever-broadening gantlet of hooks, seines, harpoons, traps and now farm-style pens, in which netted fish are raised and fattened - all to supply the Japanese sushi trade. Dr. Barbara A. Block, a marine biologist at Stanford and the lead author of a study, published in the April 28 issue of Nature, said she found it hard to believe that "a fish of this size and beauty, an animal that had captured the hearts of fishermen and scientists alike for millennia, is slipping off Earth." ...Adult bluefins, some topping half a ton and living 40 years, slice through icy or tropical waters .... ...In the paper, Dr. Block and her colleagues recommended seasonal bans on long-line fishing in spawning hot spots in the gulf. They also urged tighter controls on fishing in the Central Atlantic, where a feeding area straddles the existing boundary line and fish from both coasts congregate. Right now, that area is intensively fished by a host of countries with almost no monitoring. Without action, Dr. Block said, the western population has little hope. "If such megafauna can disappear, imagine what else is occurring?" she said. "And it's all because we do not have a system that manages the oceans properly." American boat owners say that existing restrictions on long-line fishing in the Gulf are sufficient, and add that the spawning zones identified by Dr. Block are likely to shift each year, making specific "time-area closures" impossible. Long-liners in the area also use lightweight hooks that hold smaller yellowfin but are designed to uncoil under the powerful tug of a bluefin, they say. Dr. Block said that when she worked on long-line vessels in the region, the same smaller hooks caught and killed a substantial number of bluefin. She added that only a few percent of longliners in the area carry observers who independently tally bluefin deaths. Perhaps the biggest unresolved question is whether the new information can change an international regulatory regime that almost everyone, from anglers and commercial fishers to biologists and tuna diplomats, agrees is broken. There are signs that the accumulated scientific evidence is starting to sway some members of the International Commission for the Conservation of Atlantic Tunas, the body created under a treaty in 1969 to oversee the fishery. ...In an interview last week, Masanori Miyahara, the chairman of the commission and a senior fisheries official from Japan, acknowledged that the existing system had failed. ..."We feel some responsibility for this mess," he said. "Japanese buyers are running all around the world and buying as many fish as possible, particularly bluefin.

January 2005. The Plastic Sea. by Kristi Coale, Terrain Magazine. Swirling in the Central and North Pacific Ocean is a mass of debris the size of Africa. Scientists have dubbed this mass, over which no country has authority or responsibility, the "Synthetic Sea." Why? Because it is filled with floating plastic waste. Between 1999 and 2002, Captain Charles Moore and researchers with the Algalita Marine Research Foundation made several trips to the Pacific Ocean halfway between San Francisco and Hawai'i to study the situation. What he has found is startling. Dragging trawlers behind his ship, Moore and his researchers took samples to assess the effects of the plastic on sea life. They compared the mass of zooplankton to the mass of plastic and found that for every pound of zooplankton, there were six pounds of plastic....Plastics in the San Francisco Bay and the Pacific Ocean trap, sicken, and otherwise disable an average of 25 sea lions, harbor seals, and other mammals locally each year, says Jennifer Witherspoon, formerly with the Marine Mammal Center. "Some get tangled in discarded fishing nets and packing strap, and we do save some," she explains. "We autopsy those who die, and we've found plastics and, in one instance, a sock." Externally, they can maim wildlife. Witherspoon recalls "Michelin," a sea lion found with a rubber tube around his neck; researchers had to euthanize him. An elephant seal with packing strap around her middle was lucky. "We cut the strap, and she doubled in size," says Witherspoon. "She hadn't been able to take a breath in some time." ...Sea-dwelling birds and other species do not distinguish between food and small pieces of plastic. That's because many of the plastic pieces are small and tan, resembling krill. Resin beads, or nurdles, resemble fish eggs. Birds and other animals ingest these particles, which make them feel sated, robbing them of the drive to find real food and depriving them of nutrients. Some birds, such as the albatross, regurgitate this polymer-laced meal to feed their chicks. Researchers have found shampoo bottle caps and electric wire plugs in the remains of albatross chicks.

17 March 2005. MARINE RESEARCHERS DELIVER BLUEPRINT FOR RESCUING AMERICA'S TROUBLED CORAL REEF. An international team of marine ecologists is urging the United States to take immediate action to save its fragile coral reefs. Their message is contained a strongly worded essay titled, "Are U.S. Coral Reefs on the Slippery Slope to Slime?" that appears in the March 18 edition of the journal Science.
"We're frustrated with how slowly things are moving with coral reef conservation in the United States," said Fiorenza Micheli, an assistant professor of biological sciences at Stanford University's Hopkins Marine Station. "Tiny steps are being taken, but they really don't address the overall problem."

Summer 2004. Farming For Black Gold. Can California sturgeon farms help preserve a species half a world away? by Carol Hunter. Terrain Magazine pp. 22-27. Ken Beer has a farm in the Central Valley, just about 20 miles south of Sacramento. ... while his neighbors raise dairy cattle, alfalfa and winter wheat, Beer's farm is filled with row upon row of white, circular tanks that hold about one million pounds of California white sturgeon.... inside the belly of each mature female Beer hopes he'll find the black gold of the sea: caviar. For connoisseurs and gourmets, choices about caviar are usually pretty simple. Beluga or osetra? One ounce or two? But now, people like Ken Beer are allowing consumers to face a more profound choice: wild or farm-raised? Caviar has long been equated with luxury, the food of kings and czars. But while the sturgeons that produce caviar were once abundant in the oceans, lakes, and seas of the northern hemisphere, they have been fished to dangerously low levels around the world. In North America, five of the nine species of sturgeon and closely related paddlefish are federally listed as endangered, while in the Caspian Sea, which historically has been home to the world's largest abundance of sturgeon, annual catches have dropped by 95 percent in the last hundred years, from over 20,000 tons in the early 1900s to only 1000 tons in the late 1990s. While many government and international agencies have tried to regulate sturgeon fisheries, the high price of caviar, which can sell for well over $100 an ounce, continues to draw poachers and black market smugglers into an illegal trade....Ken Beer wasn't thinking of saving threatened species when he started studying sturgeon aquaculture 25 years ago. He had been raising catfish for about three years and was thinking of ways to make his farm more efficient. ...Because sturgeon farming uses a land-based facility with fresh water, it avoids many of the harmful environmental effects of other aquaculture, like open-water salmon farming. There are no escapes and mixing of gene pools, no contamination of wild species with diseases or parasites, and no flow of wastes directly into any open water resource.

21 December 2004. As the Seas Warm, Algae Help Some Coral Stand Up to the Heat. NY Times- By CORNELIA DEAN . KEY LARGO, Fla. - For some time, scientists have predicted that the world's coral reefs will be among the first ecosystems to suffer devastating damage from global warming. Some reefs, however, are proving surprisingly resilient, researchers say, not because of qualities of the corals themselves, but because of heat-tolerant algae that live with them. It may even be possible that heat-related episodes of coral bleaching, which had been viewed as ominous previews of mass coral death to come, could allow these robust algae to spread, leaving corals better able to survive in a warmer world. The scientists say this strength in the face of warming will not be enough to save the world's coral reefs, which are threatened by pollution, overfishing, tourism and other human activities. But if the findings hold up, "they essentially buy us time" to address those issues, said Dr. Andrew C. Baker of the Marine Program of the Wildlife Conservation Society, who led the new work.

2 November 2004. NASA RELEASE: 04-355. NASA & PARTNERS CREATE NEW WORLDWIDE CORAL REEF LIBRARY. A NASA-funded project has created an archive of approximately 1,500 images of worldwide coral reefs. The archive is a tool international researchers will use, as they track reef health. The collection of coral reef images is the basis for a new Internet-based library for the Millennium Coral Reef Project. It was created in a partnership between NASA and the University of South Florida (USF), Tampa, Fla. Additional contributors, including the National Oceanic and Atmospheric Administration, international agencies and other universities, shared data, so natural resource managers could have a comprehensive world data resource on coral reefs and adjacent land areas.

15 July 2004. Coalition Warns Navy Over Destructive Use of Mid-Frequency Sonar. Conservation and Animal Welfare Groups Decry Needless Harm to Whales and Other Species; Request Talks After Latest in String of Sonar-Linked Whale Deaths. LOS ANGELES - A coalition of conservation and animal welfare groups yesterday threatened to take formal action against the U.S. Navy unless it agrees to adopt common sense measures to mitigate harm to marine mammals and fish caused by the Navy's use of mid-frequency, high intensity active sonar. The coalition includes NRDC (Natural Resources Defense Council), The International Fund for Animal Welfare (IFAW), The Humane Society of the United States (The HSUS) and Jean-Michel Cousteau's Ocean Futures Society. In a 13-page letter sent Wednesday to Navy Secretary Gordon England, the coalition detailed numerous mass strandings and mortalities of whales associated with the Navy's testing and training with mid-frequency sonar systems. http://www.nrdc.org/media/pressreleases/040715.asp and http://www.nrdc.org/wildlife/marine/nlfa.asp

Spring 2003. Deep Trouble. Article by Ben Raines from On Earth-NRDC. IN THE GULF OF MEXICO, IT'S BEST TO LET THE BIG ONES GETAWAY. On July 22, 2001, Alabama's Mobile Register (circulation 100,000) published its first article on methylmercury contamination in Gulf seafood. The investigative series that ensued, with more than forty articles to date, has shown not only that methylmercury has entered the human population by way of Gulf fish, but also that federal agencies charged with protecting people from such contamination have failed to do so. For the series, Ben Raines was awarded the 2002 John B. Oakes Award for Distinguished Environmental Journalism. The stories that follow are compiled from a few of his original reports.
