(05/22/2012) Twenty-two conservation, indigenous, health and science groups have called on U.S. President Barack Obama to attend the up-coming Rio+20 Summit on Sustainable Development.
Seagrass beds store 20 billion tons of carbon
(05/22/2012) Just below the ocean's surface lies a carbon powerhouse: seagrass meadows. New research in Nature Geoscience estimates that the world's seagrass meadows conservatively store 19.9 billion metric tons of carbon, even though the threatened marine ecosystems make up only 0.2 percent of Earth's surface. The findings lend support to the idea that seagrass protection and restoration could play a major role in mitigating climate change.
Jaguar v. sea turtle: when land and marine conservation icons collide
(05/16/2012) At first, an encounter between a jaguar (Panthera onca) and a green sea turtle (Chelonia mydas) seems improbable, even ridiculous, but the two species do come into fatal contact when a female turtle, every two to four years, crawls up a jungle beach to lay her eggs. A hungry jaguar will attack the nesting turtle, killing it with a bite to the neck, and dragging the massive animal—sometime all the way into the jungle—to eat the muscles around the neck and flippers. Despite the surprising nature of such encounters, this behavior, and its impact on populations, has been little studied. Now, a new study in Costa Rica's Tortuguero National Park has documented five years of jaguar attacks on marine turtles—and finds these encounters are not only more common than expected, but on the rise.
Wildlife in the tropics plummets by over 60 percent
(05/15/2012) In 48 years wildlife populations in the tropics, the region that holds the bulk of the world's biodiversity, have fallen by an alarming 61 percent, according to the most recent update to the Living Planet Index. Produced by the World Wide Fund for Nature (WWF) and the Zoological Society of London (ZSL), the index currently tracks almost 10,000 populations of 2,688 vertebrate species (including mammals, birds, reptiles, amphibians, and fish) in both the tropics and temperate regions.
Educating the next generation of conservation leaders in Colombia
(05/14/2012) Colombia's northern departments of Cordoba and Bolivar are home to an abundance of coral reefs, estuaries, mangroves forests, and forests. Rich in both marine and terrestrial wildlife, local communities depend on the sea and land for survival, yet these ecosystems are imperiled by booming populations, overexploitation, and unsustainable management. Since 2007, an innovative education program in the region, the Guardians of Nature, has worked to teach local children about the ecology of the region, hoping to instill a conservation ethic that will aid both the present and the future.
Manta rays tracked by satellite
(05/11/2012) Satellite tracking technology has revealed new insights into the behavior of manta rays, reports the Wildlife Conservation Society (WCS). The findings are published in this week's issue of the journal PLoS.
Featured video: the oceans and Rio+20
(05/10/2012) A new video by Pew Environment Group and the Zoological Society of London (ZSL) hopes to convince policy-makers attending the Rio+20 Summit on Sustainable Development this summer that urgent action is needed to save the ocean's from an environmental crisis.
Video: All white killer whale spotted in Russia
(04/27/2012) Scientists in Russia have captured the first-known video footage of an all-white killer whale.
BP Deepwater Horizon deformities: eyeless shrimp, clawless crabs
(04/24/2012) Two years after the BP-leased Deepwater Horizon drilling rig exploded in the Gulf of Mexico, killing eleven and causing an oil spill that lasted three months, scientists say the impacts on the Gulf ecosystem are only beginning to come to light and the discoveries aren't pretty.
Featured video: Google Earth highlights imperiled coral reefs around the world
(04/18/2012) A new video by Google Earth and the World Resources Institute (WRI) highlights the world's many endangered coral reefs. A part of the WRI's Reefs at Risk program, the video highlights regional and global threats to the oceans' most biodiverse ecosystem. According to the WRI, a stunning 75 percent of the world's reefs are currently threatened.
Papua New Guinea halts controversial nickel mine - for now
(04/16/2012) A massive, controversial nickel mine has been shut down in Papua New Guinea due to the environmental concerns of its slurry pipeline, reports Cultural Survival. Inspections of the 83 mile (134 kilometer) slurry pipeline found that it had been built too close to a major highway with spills already impacting traffic. Built by the Chinese state company Metallurgical Construction Corporation (MCC), the Ramu Nickel Mine has been plagued by land issues, labor disputes, and environmental concerns.
Whole Foods bans 'red' fish from its stores
(04/10/2012) Whole Foods has announced it will be the first grocery chain in the U.S. to no longer sell any seafood in the "red." Based on sustainability ratings by the Monterey Bay Aquarium and Blue Ocean Institute, fish labeled red are those that are considered either overfished or fished in a manner that impacts other species or damages marine ecosystems. Beginning Earth Day, April 22nd, Whole Foods will no longer be selling Atlantic halibut, grey sole, skate, octopus, tautog, sturgeon, among others. Already, the store doesn't sell some unsustainable catches such as bluefin tuna and orange roughy.
Oceans heating up for over 100 years
(04/02/2012) In 1872 the HMS Challenger pulled out from Portsmouth, England to begin an unprecedented scientific expedition of the world's oceans. During its over three year journey the HMS Challenger not only collected thousands of new species and sounded unknown ocean depths, but also took hundreds of temperature readings—data which is now proving invaluable to our understanding of climate change.
NASA image shows decline in maximum sea ice extent
(03/28/2012) Data released by the National Snow and Ice Data Center (NSIDC) shows that Arctic sea ice for the winter of 2011-2012 reached its maximum extent on March 18 at 15.24 million square kilometers (5.88 million square miles). The mark is well below the 1979–2000 average, but was above the record low of the 2010–2011 winter.
Beyond Bigfoot: the science of cryptozoology
(03/26/2012) Anyone who doubts cryptozoology, which in Greek means the "study of hidden animals," should remember the many lessons of the past 110 years: the mountain gorilla (discovered in 1902), the colossal squid (discovered in 1925, but a full specimen not caught until 1981), and the saola (discovered in 1992) to name a few. Every year, almost 20,000 new species are described by the world's scientists, and a new book by Dr. Karl Shuker, The Encycloapedia of New and Rediscovered Animals, highlights some of the most incredible and notable new animals uncovered during the past century.
Animal picture of the day: a sun-colored weedy scorpion fish
(03/26/2012) This bright yellow weedy scorpion fish (Rhinopias frondosa) is the newest member of the Wildlife Conservation Society's (WCS) New York Aquarium. Weedy scorpion fish are found in the Indo-Pacific Ocean and in a wide variety of colors.
World's smallest dolphin: only 55 left, but continue to drown in nets
(03/22/2012) The world's smallest dolphin is also the closest to extinction. New Zealand government figures show that Maui's dolphin (Cephalorhynchus hectori maui) are down to just 55 mature individuals, falling from 111 in 2005. The small cetaceans, measuring up to 1.7 meters (5.5 feet), are imperiled due to drowning in gillnets with the most recent death by a fisherman's net occurring in January.
Three U.S. retailers pledge to avoid fish from embattled Ross Sea
(03/14/2012) The Ross Sea, a massive bay off Antarctica, has been dubbed the world's last ocean due to its pristine state, long-untouched by industry and fisheries. However, over the last 15 years New Zealand commercial fisheries have entered the sea, seeking the slow-growing Antarctic toothfish which is usually sold as the high-end Chilean sea bass. Now as conservation groups plead for nations to grant the Ross Sea protected status, Greenpeace has begun a campaign to get good retailers to steer clear of stocking Antarctic toothfish. To date, Safeway, Wegmans, and Harris Teeter has all pledged not to source from the Ross Sea.
Camera traps go under the ocean, seeking sharks
(03/12/2012) Remote camera traps, which have become a hugely important conservation tool on land during the past decade, have now gone underwater. Marine biologists have used underwater video camera traps to compare the population of Caribbean reef sharks (Carcharhinus perezii) in Belize's protected areas versus fishing areas in a new study in the open-access journal PLoS ONE. Conducted from 2005-2010, the study found that reef sharks benefited significantly from conservation areas.
Animal photos of the day: green sea turtle saved in China
(03/06/2012) Last month, an organization devoted to marine turtles in the China, Sea Turtle 911, released a green sea turtle (Chelonia mydas) back into the wild in an event that included adoring crowds and a lecture on sea turtle conservation. The sea turtle, dubbed "Crush," had been rescued from a local fishing village. Green sea turtles are listed as Endangered by the IUCN Red List. "Despite the endangered status of sea turtles, there remains a thriving illegal market for sea turtle meat and products in China," a press release from Sea Turtle 911 notes.
Sawfish impale, cleave prey with snout
(03/05/2012) Although all seven species of sawfish are nearly extinct, scientists have spent little time studying these vanishing species. However that is changing as a new study in Current Biology sheds light on the sawfishes' most distinguishing feature: its long toothed snout, which gives the fish its name. "I was surprised to see how skilled sawfish are with their saw," said co-author Barbara Wueringer of the University of Queensland in a press release. "They use their saw to impale prey on the rostral teeth by producing several lateral swipes per second."
Carbon emissions paving way for mass extinction in oceans
(03/05/2012) Human emissions of carbon dioxide may be acidifying the oceans at a rate not seen in 300 million years, according to new research published in Science. The ground-breaking study, which measures for the first time the rate of current acidification compared with other occurrences going back 300 million years, warns that carbon emissions, unchecked, will likely lead to a mass extinction in the world's oceans. Acidification particularly threatens species dependent on calcium carbonate (a chemical compound that drops as the ocean acidifies) such as coral reefs, marine mollusks, and even some plankton. As these species vanish, thousands of others that depend on them are likely to follow.
Scientists recommend marine protected areas for Madagascar
(02/27/2012) With the government of Madagascar planning to increase marine protected areas by one million hectares, a group of researchers have laid out flexible recommendations in a new study in the open access journal PLoS ONE. The researchers employed four different analyses in order to highlight a number of different conservation options, however the different analyses pointed to the need to protect certain areas with high biodiversity, including the Barren Islands' reefs, the reefs of Juan de Nova, the Banc de Leven, and the shallow banks of the Cap Sainte Marie.
Amazon.com stops selling whale meat
(02/22/2012) Amazon Japan, a subsidiary of Amazon.com, pulled all whale meat products (and possibly dolphin meat) from its site after a new report by the Environmental Investigation Agency (EIA) and the Humane Society International highlighted the issue. Last December the organizations recorded 147 whale products on sale at Amazon Japan despite an international whaling moratorium since 1986. Japan, along with Iceland and Norway, continues to industrially hunt whales. Japan says their whale hunt is for scientific purposes only, but environmentalists dispute this.
Washing clothing pollutes oceans with billions of microplastics
(02/14/2012) Washing synthetic clothes—such as nylon, polyester, and acrylic—is polluting the oceans with billions of microplastics: plastics that measure less than one millimeter. It may sound innocuous, but research has shown that these microplastics are accumulating in marine species with unknown health impacts, both on the pollution-eating species and the humans who consume them.
Opposition rising against U.S. Arctic drilling
(02/09/2012) Drilling in the Arctic waters of the U.S. may become as contested an issue as the Keystone Pipeline XL in up-coming months. Scientists, congress members, and ordinary Americans have all come out in large numbers against the Obama Administration's leases for exploratory drilling in the Beaufort Sea and the Chuckchi Sea.
Black Swans and bottom-up environmental action
(02/08/2012) The defining events shaping the modern world - economic, social, environmental, progressive and disruptive - are frequently characterized as "Black Swans."The Black Swan term and theory were characterized by author and analyst Nassim Nicholas Taleb who explains, "What we call here a Black Swan (and capitalize it) is an event with the following three attributes. First, it is an outlier, as it lies outside the realm of regular expectations, because nothing in the past can convincingly point to its possibility. Second, it carries an extreme impact. Third, in spite of its outlier status, human nature makes us concoct explanations for its occurrence after the fact, making it explainable and predictable." Taleb identifies the emergence of the internet, the attacks of September 11, 2001, the popularity of Facebook, stock market crashes, the success of Harry Potter, and World War I as among Black Swan events.
Jellyfish explosion may be natural cycle
(02/06/2012) Evidence that jellyfish are taking over the oceans is currently lacking, according to a new study published in Bioscience. Complied by a number of marine experts, the study found that while jellyfish have been on the rise in some regions it is likely due to a natural cycle of jellyfish populations and not a global boom. Researchers, including a number of marine biologists, have warned for years that jellyfish numbers may be exploding due to human activities, such as overfishing, warmer oceans due to global climate change, and the rise of oxygen-depleted, so-called "dead zones."
Atlantic sturgeon gains protection under the Endangered Species Act
(02/01/2012) The U.S. federal government has listed the massive and bizarre Atlantic sturgeon (Acipenser oxyrinchus) under the protection of the Endangered Species Act (ESA). Historically overfishing decimated the Atlantic sturgeon, while on-going threats include pollution and infrastructure, like dams and bridges that destroy habitat. Fishing for the Atlantic sturgeon has been banned since 1998, they are still caught as bycatch.
Climate and The Oceans - Princeton Primers in Climate: A Book Review
(01/25/2012) Climate and The Oceans by Dr. Geoffrey K. Vallis provides a coherent, well-articulated primer on how the oceans impact the Earth's climate. This easy-to-read illustrated book, filled with both data and accessible mathematical equations demonstrating the impact of the oceans on the Earth's climate, offers practitioners and stakeholders' state-of-the-art scientific analysis of how the oceans and climate interact that is both user friendly to the non-expert yet scientifically rigorous enough as bridge material for graduate students as they grapple with the compelling field of climate science and oceanography.
87 marine mammals still eaten by people
(01/24/2012) Threats to marine mammals usually include climate change, drowning as by-catch, pollution, depletion of prey, but what about eating marine mammals? A new study in Biological Conservation finds that a surprising 87 marine mammals—including polar bears, small whales, and dolphins—have been eaten as food since 1990 in at least 114 countries.
Acid oceans: in some regions acidification a 'hundred times greater' than natural variation
(01/24/2012) Emissions of carbon over the last two centuries have raised the acidity of the oceans to the highest levels in 21,000 years and likely beyond, according to a new study in Nature Climate Change. The change threatens a number of marine species, including coral reefs and molluscs.
Leatherback sea turtles granted massive protected area along U.S. west coast
(01/23/2012) The U.S. federal government has designated 108,556 square kilometers (41,914 square miles) as critical habitat for the leatherback sea turtle (Dermochelys coriacea), the largest of the world's marine turtles and one of the most endangered. The protected area, around the size of Guatemala, spans coastal sea waters from California to Washington state, but does not protect the migration routes environmentalists hoped for.
Hugh Powell: birds lend invaluable insight into ecosystems
(01/23/2012) Hugh Powell is science editor at the Cornell Lab of Ornithology as well as a contributor to Woods Hole Oceanographic Institution's Oceanus and other publications. He's traveled extensively while writing, including stints in Antarctica for WHOI's Live from the Poles. Before finding his niche as a science writer, Hugh studied the interconnections between black-backed woodpeckers, insects, and forest fires in Montana. He currently resides in Ithaca, New York.
Biofuel breakthrough: kelp could power cars
(01/20/2012) Scientists have devised a new way to produce ethanol directly from seaweed, offering the potential to generate biofuels that don't compete with terrestrial food production and won't suck up scarce freshwater, reports a study published today in Science.
New book series hopes to inspire research in world's 'hottest biodiversity hotspot'
(01/17/2012) Entomologist Dmitry Telnov hopes his new pet project will inspire and disseminate research about one of the world's last unexplored biogeographical regions: Wallacea and New Guinea. Incredibly rich in biodiversity and still full of unknown species, the region, also known as the Indo-Australian transition, spans many of the tropical islands of the Pacific, including Indonesia's Sulawesi, Komodo and Flores, as well as East Timor—the historically famous "spice islands" of the Moluccan Archipelago—the Solomon Islands, and, of course, New Guinea. Telnov has begun a new book series, entitled Biodiversity, Biogeography and Nature Conservation in Wallacea and New Guinea, that aims to compile and highlight new research in the region, focusing both on biology and conservation. The first volume, currently available, also includes the description of 150 new species.
Featured video: tuna industry bycatch includes sea turtles, dolphins, whales
(01/16/2012) A Greenpeace video, using footage from a whistleblower, shows disturbing images of the tuna industry operating in the unregulated waters of the Pacific Ocean. Using fish aggregation devices (FADs) and purse seine nets, the industry is not only able to catch entire schools of tuna, including juvenile, but also whatever else is in the area of the net.
How much is the life of a whale worth?
(01/16/2012) How do you end a decades-long conflict between culture and conservation? How do you stop a conflict where both sides are dug in? A new paper in Nature proposes a way to end the long and bitter battle over whaling: environmentalists could pay whalers not to whale.
Cute animal picture of the day: pygmy killer whale saved after stranding
(01/12/2012) On Tuesday a female pygmy killer whale (Feresa attenuata) was found stranded on Tanjung Aru beach, in the Malaysian state of Sabah on the island of Borneo. After being moved to a swimming enclosure at a local resort for recuperation, the whale was released back into the wild with aid from the Sabah Wildlife Department, marine biologist Lindsay Porter, the local NGO LEAP, and WWF Malaysia.
Bycatch-reducing fish trap wins $20,000
(01/11/2012) An innovative fish trap that allows small non-target fish to escape won a new content by RARE Conservation and National Geographic to fund solutions to overfishing. Developed through studies in Curaçao and Kenya with the Wildlife Conservation Society, the trap has gaps for juvenile fish to swim out of reportedly reducing bycatch by 80 percent. The entry won a $20,000 grant.
Photos: scientists find new species at world's deepest undersea vent
(01/10/2012) It sounds like a medieval vision of hell: in pitch darkness, amid blazing heat, rise spewing volcanic vents. But there are no demons and devils down here, instead the deep sea vent, located in the very non-hellish Caribbean sea, is home to a new species of pale shrimp. At 3.1 miles below (5 kilometers) the sea's surface, the Beebe Vent Field south of the Cayman islands, is the deepest yet discovered.
World's most expensive tuna
(01/05/2012) A 593 pound Pacific bluefin tuna sold for $735,000 (56.49 million yen) in Tokyo's Tsukiji market today. This beats the previous record price hit last year by over $260,000. Why so expensive? Bluefin tuna, considered the best sashimi and sushi in the world, have been fished to near extinction with the population of the Pacific bluefin the most stable to date.
'Lost world' dominated by Yeti crabs discovered in the Antarctic deep
(01/03/2012) Scientists have discovered a deep sea ecosystem dominated by hairy pale crabs off of Antarctica. The new species of "Yeti crabs" survive alongside many other likely new species, including a seven-armed meat-eating starfish, off of hydrothermal vents, which spew heat and chemicals into the lightless, frigid waters. According to the paper published in PLoS ONE, this is the first discovery of a hydrothermal vent ecosystem in the Southern Ocean though many others have been recorded in warmer waters worldwide.
The biggest new species discoveries in 2011
(12/26/2011) Every year scientists describe thousands of species for the first time. 2011 was no different, so here's a look at some of the significant new species discoveries for the year. New species discoveries are bound to continue as genetic analysis becomes more widespread and scientists conduct surveys of ever more habitats. But species loss also continues, and that is something considerably more difficult to quantify. Cataloging the disappearance of a species is extremely costly -- final proof can take years. Nonetheless in 2011 the book was closed on two particularly conspicuous creatures: neither the Vietnamese rhino nor the western black rhino roam the wilds any more.
Top 10 Environmental Stories of 2011
(12/22/2011) Many of 2011's most dramatic stories on environmental issues came from people taking to the streets. With governments and corporations slow to tackle massive environmental problems, people have begun to assert themselves. Victories were seen on four continents: in Bolivia a draconian response to protestors embarrassed the government, causing them to drop plans to build a road through Tipnis, an indigenous Amazonian reserve; in Myanmar, a nation not known for bowing to public demands, large protests pushed the government to cancel a massive Chinese hydroelectric project; in Borneo a three-year struggle to stop the construction of a coal plant on the coast of the Coral Triangle ended in victory for activists; in Britain plans to privatize forests created such a public outcry that the government not only pulled back but also apologized; and in the U.S. civil disobedience and massive marches pressured the Obama Administration to delay a decision on the controversial Keystone XL pipeline, which would bring tar sands from Canada to a global market.
Yeti crab cultivates bacteria on its claws to feed itself
(12/02/2011) A species of deep-sea crab found in hydrothermal vents off Costa Rica cultivates "gardens" of bacteria on its claws to feed itself, reports Nature News.
Arctic sea ice melt 'unprecedented' in past 1,450 years
(11/24/2011) Recent arctic sea ice loss is 'unprecedented' over the past 1,450 years, concludes a reconstruction of ice records published in the journal Nature.
Bathtub-sized marine sponge rediscovered after a century of extinction
(11/22/2011) Not found alive for over a century the evocatively named Neptune's cup sponge (Cliona patera) has been rediscovered off the shores of Singapore. Researchers with the environmental consulting DHI Group found the species during a routine dive. Although the specimen they found was small, the goblet-shaped sponge can reach nearly 5 feet (1.5 meters) high and the same in diameter.
Picture of the day: Ocean in Focus photo contest winner
(11/22/2011) A photo of a shark with a rusting hook in its maw is the grand prize winner of the Ocean in Focus photo contest, which seeks to raise awareness for conservation issues in the oceans.
Seahorses under stress
(11/21/2011) With about 25 million seahorses sold each year, global consumption of seahorses is massive. They’re used in traditional Asian medicine and also sold as curios and aquarium pets. Over the last decade, overexploitation and habitat degradation have prompted declines of between 15 to 70 percent in many seahorse populations. Marine biologist and author Helen Scales notes there is much still unknown about seahorses.
