Opposition rising against U.S. Arctic drilling

2012-02-09T22:03:00Z

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

2012-02-08T15:13:00Z

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

2012-02-06T13:18:00Z

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

2012-02-01T21:26:00Z

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

2012-01-25T17:50:00Z

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

2012-01-24T22:55:00Z

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

2012-01-24T18:00:00Z

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

2012-01-23T20:51:00Z

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.

New book series hopes to inspire research in world's 'hottest biodiversity hotspot'

2012-01-17T23:13:00Z

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

2012-01-16T16:43:00Z

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?

2012-01-16T12:30:00Z

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

2012-01-12T18:39:00Z

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

2012-01-11T22:11:00Z

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

2012-01-10T16:06:00Z

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

2012-01-05T16:15:00Z

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

2012-01-03T22:57:00Z

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

2011-12-26T18:58:00Z

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.

Yeti crab cultivates bacteria on its claws to feed itself

Seahorses under stress

2011-11-21T18:50:00Z

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.

U.S. pledges $450 m to Indonesia for green economic growth

Antarctic king crabs warming up to invade continental shelf, threatening unique marine community

2011-11-15T19:46:00Z

Dangerous and disruptive king crabs lurk in a deep pocket of the Antarctic continental shelf, clamoring to escape their cold-water prison to reach and permanently change the shallower, prehistoric paradise above. A team led by University of Hawaii oceanographer Craig Smith spotted the meter-long monsters in February 2010. It was the first time researchers have seen king crabs on the continental shelf.

US reduces catch limit of 'most important fish in the sea'

2011-11-15T17:26:00Z

The Atlantic State Marine Fisheries Commission (ASMFC) has slashed the allowable catch of a tiny fish named menhaden by 37 percent by 2013. Dubbed the 'most important fish in the sea' by author H. Bruce Franklin, the menhaden plays a critical role in marine ecosystems as a food source for larger fish, seabirds, and marine mammals, as well as helping to regulate the marine environment. However, due to overfishing the menhaden fish has dropped 92 percent from its historical population.

Covert Creatures: The Clandestine Lives of Seahorses

2011-11-15T06:06:00Z

Seahorses are strange looking creatures, with a horse's head on top of a kangaroo’s pouched belly, bulging, swiveling chameleon eyes, a prehensile monkey tail, color-changing armor and a royal crown, all shrunk down to the size of a chess piece. To marine biologist Helen Scales, these elusive creatures are a perfect symbol of the ocean's biodiversity.

Tracking the coelacanth: Two decades of research confirms a viable population in Comoros

2011-11-14T17:34:00Z

It took a custom-made submarine, billionaire Paul Allen, and a tenacious desire lasting well beyond two decades to unveil enigmatic details about the life of the coelacanth—the primitive fish that invariably hooks researchers. A study published earlier this year in the journal Marine Biology summarizes 21 years of coelacanth population research by one team, led by Hans Fricke of the Max Planck Institute for Marine Microbiology in Bremen, Germany. Working in the Indian Ocean off the African island nation of Comoros, Fricke documented a stable population of Latimeria chalumnae. However, his study notes that deep-set fishing nets could threaten these unique animals.

First global assessment finds highest-grossing tunas and billfishes most vulnerable to extinction

2011-11-09T17:50:00Z

Sleek, powerful tunas and billfishes that ply the open ocean garner some of the highest prices of any fish. In January, a single bluefin tuna fetched a record $396,000 at a Tokyo auction. Yet wild fish populations pay a still higher price for such exorbitant demand: the threat of extinction. The first assessment of an entire group of commercially valuable marine species found that the most threatened fish are generally the ones reeling in the most money, including bluefin tuna and bigeye tuna.

Researchers challenge idea that marine reserves promote coral recovery

2011-11-09T11:16:00Z

Fleshy whorls of thick brown algae blanket the once-vibrant corals in Glover’s Reef, Belize. According to a controversial study published August 14 in the journal Coral Reefs, a decade of marine reserve protection has failed to help these damaged Caribbean corals recover.

Coral reef biodiversity may be vastly underestimated

2011-11-03T21:00:00Z

Researchers with the Smithsonian have catalogued almost as many crab species on tropical coral reef bits measuring just 20.6 square feet (6.3 square meters) as in all of Europe's seas, finds a new paper in PLoS ONE. The team used DNA barcoding to quickly identify a total of 525 crustaceans (including 168 crab species) from dead coral chunks taken from seven sites in the tropics, including the Indian, Pacific and Caribbean oceans.

11 challenges facing 7 billion super-consumers

2011-10-31T00:05:00Z

Perhaps the most disconcerting thing about Halloween this year is not the ghouls and goblins taking to the streets, but a baby born somewhere in the world. It's not the baby's or the parent's fault, of course, but this child will become a part of an artificial, but still important, milestone: according to the UN, the Earth's seventh billionth person will be born today. That's seven billion people who require, in the very least, freshwater, food, shelter, medicine, and education. In some parts of the world, they will also have a car, an iPod, a suburban house and yard, pets, computers, a lawn-mower, a microwave, and perhaps a swimming pool. Though rarely addressed directly in policy (and more often than not avoided in polite conversations), the issue of overpopulation is central to environmentally sustainability and human welfare.

Small marine fish need protection too

2011-10-25T20:58:00Z

It has long been known that overfishing has decimated some populations of tuna, shark, cod, as well as other big predatory fish; however two recent studies have pointed out that overfishing is also threatening small fish such as anchovies, sardines, mackerel, herring, menhaden, and krill. Although tiny, these species are vital to marine ecosystems since many species higher up on the food chain—from seabirds to marine mammals to big fish—wholly depend on them for survival.

Giant one-celled organisms discovered over six miles below the ocean's surface

2011-10-23T16:18:00Z

Imagine a one-celled organism the size of a mango. It's not science fiction, but fact: scientists have cataloged dozens of giant one-celled creatures, around 4 inches (10 centimeters), in the deep abysses of the world's oceans. But recent exploration of the Mariana Trench has uncovered the deepest record yet of the one-celled behemoths, known as xenophyophores.

Photos: satellite tracking of the unicorn of the sea

2011-10-19T16:03:00Z

A new program aims to track one of the ocean's most enigmatic creatures: the narwhal (Monodon monoceros). Tagging nine narwhales in August, researchers plan to track the species in order to gain new insights about how the little-known toothed whale will withstand a rapidly melting Arctic due to climate change. "[This] is a chance to better understand these animals while their world changes around them. We know narwhals are often associated with sea ice, and we know the sea ice is shrinking. WWF is trying to understand how narwhals, as well as all other ice associated animals in the arctic can adapt to a changing environment," says Peter Ewins with WWF-Canada.

Fishing industry exceeds Atlantic bluefin quota by 141 percent

2011-10-18T14:26:00Z

In 2010 the fishing industry exceeded its quota of eastern Atlantic bluefin tuna (Thunnus thynnus) by 141 percent, according to a new analysis by Pew Environment Group. The analysis depends on official data, thereby leaving out the massive black market on Atlantic bluefin tuna.

Bird-killing oil spill New Zealand's 'worst environmental disaster'

2011-10-12T18:36:00Z

An oil spill from a grounded container ship in New Zealand's Bay of Plenty is threatening to worsen as authorities fear the ship is breaking up. Already, 350 tons of oil from the ship, the MV Rena, has leaked out with some reaching nearby beaches including a popular holiday spot, Papamoa Beach. To date the spill has killed over 200 birds, including little blue penguins, shags, petrels, albatrosses and plovers. If the ship breaks up and sinks, authorities fear it could release its remaining 1,400 tons into the marine ecosystem.

Marshall Islands creates world's biggest shark park

2011-10-03T17:50:00Z

The Republic of the Marshall Islands has created the world's biggest shark reserve: so large that all of Mexico could fit comfortably inside. With new legislation, commercial shark fishing is now completely banned in Marshall Islands' 768,547 square miles (1,990,530 square kilometers) of ocean.

Colombian president: no oil drilling in award-winning Seaflower marine reserve

2011-10-03T17:02:00Z

Colombian president, Juan Manuel Santos, announced over the weekend that there will be no oil exploration in the award-winning Seaflower Biosphere Reserve and Marine Protected Area (MPA). Spreading over 65,000 square kilometers (6,500,000 hectares), Seaflower MPA is home to over a hundred coral species, over 400 fish, some 150 birds, four marine turtles species, and the magnificent mollusk, the queen conch (Strombus gigas).

Deepwater spill 'meets the Titanic': groups sue to stop Arctic drilling

2011-09-29T22:31:00Z

Following the Obama administration's approval of Royal Dutch Shell to drill in the Arctic's Beaufort Sea, a wide-swathe of environmental have filed a lawsuit to stop the drilling, which could begin as early as next summer. Those filing the lawsuit today blasted Shell for what they perceived as a pathetic oil spill response plan, and the Obama administration for acquiescing to the big oil company.

Deepwater oil spill likely to hurt fish populations over decades

2011-09-28T19:21:00Z

Oil pollution doesn't have to kill fish to have a long-term impact, according to a recent study in the Proceedings of the National Academy of Sciences (PNAS). Researchers found that Gulf killifish (Fundulus grandis) that had been exposed to very low to non-detectable levels of oil contamination from the Deepwater oil spill last year, still showed developmental problems that are likely to impact fish populations for decades to come.

Sowing the seeds to save the Patagonian Sea

2011-09-07T21:07:00Z

With wild waters and shores, the Patagonia Sea is home to a great menagerie of marine animals: from penguins to elephants seals, albatrosses to squid, and sea lions to southern right whales. The sea lies at crossroads between more northern latitudes and the cold bitter water of the Southern Ocean, which surround Antarctica. However the region is also a heavy fishing ground, putting pressure on a number of species and imperiling the very ecosystem that supplies the industry. Conservation efforts, spearheaded by marine conservationist Claudio Campagna and colleagues with the Wildlife Conservation Society (WCS), are in the early stages. Campagna, who often writes about the importance of language in the fight for preservation, has pushed to rename the area to focus on its stunning wildlife.

California moves closer to banning shark fin trade

2011-09-07T15:34:00Z

California moved a step closer to banning the sale and trade of shark fin with the passage Tuesday of Senate Bill 376. The bill, which passed 25-9, now goes the governor, whose approval would make the ban law. The bill was introduced to the California State Assembly February this year by Paul Fong (D-Cupertino) and Jared Huffman (D-San Rafael).
