(12/10/2013) 1. Carbon concentrations hit 400ppm while the IPCC sets global carbon budget: For the first time since our appearance on Earth, carbon concentrations in the atmosphere hit 400 parts per million. The last time concentrations were this high for a sustained period was 4-5 million years ago when temperatures were 10 degrees Celsius higher. Meanwhile, in the slow-moving effort to curb carbon emissions, the Intergovernmental Panel on Climate Change (IPCC) crafted a global carbon budget showing that most of the world's fossil fuel reserves must be left untouched if we are to avoid catastrophic climate change.
China bans shark fin, bird's nest soup from state banquets
(12/10/2013) China has banned shark fin and bird's nest soup from being served at official state banquets, reports Chinese state media.
Animal Earth: exploring the hidden biodiversity of our planet
(12/03/2013) Most of the species on Earth we never see. In fact, we have no idea what they look like, much less how spectacular they are. In general, people can identify relatively few of their backyard species, much less those of other continents. This disconnect likely leads to an inability in the general public to relate to biodiversity and, by extension, the loss of it. One of the most remarkable books I have read is a recent release that makes serious strides to repair that disconnect and affirm the human bond with biodiversity. Animal Earth: The Amazing Diversity of Living Creatures written by Ross Piper, a zoologist with the University of Leeds, opens up the door to discovery.
Google Earth reveals fish catch is 6 times greater than thought in Persian Gulf
(11/27/2013) Google Earth has once again been used by researchers for scientific discovery.
Leatherback sea turtle no longer Critically Endangered
(11/26/2013) The leatherback sea turtle—the world's largest turtle and the only member of the genus Dermochelys—received good news today. In an update of the IUCN Red List, the leatherback sea turtle (Dermochelys coriacea) has been moved from Critically Endangered to Vulnerable. However, conservationists warn that the species still remains hugely endangered—and in rapid decline—in many parts of its range.
Gulf of Mexico deep sea may need decades to recover from oil spill
(11/20/2013) The catastrophic explosion that spewed some five million barrels of oil deep into the Gulf of Mexico in April 2010 will take a heavy toll in the ocean’s lowest layers for years to come. That’s the stark conclusion of seafloor research conducted six months after the Deepwater Horizon oil spill. The study, published on August 7 in PLoS ONE, examined life in the Gulf’s deepest waters near the blowout, about 1.6 kilometers below the surface. Here, the researchers found that the damages will take decades to reverse.
Coelacanths might be monogamous, to the surprise of researchers
(11/14/2013) They evaded humans for millions of years and live very private lives. The hulking, fleshy-finned fish known as the coelacanth has beguiled scientists for generations. But the coelacanth mystique that enchants researchers also makes it difficult to study. Researchers recently revealed in Nature Communications one startling aspect of the coelacanth lifestyle: they might be monogamous.
Longline fisheries in Costa Rica hook tens of thousands of sea turtles every year
(11/14/2013) Hundreds of kilometers of commercial fishing lines slither along coastal waters in Costa Rica, hooking thousands of mahi-mahi and many other marketable fish. But when scientists scrutinized fishermen’s catch, they were shocked by the staggering number of sea turtles accidentally snagged on the lines.
Fishermen get crafty to circumvent shark fin ban
(11/10/2013) Authorities in Costa Rica have identified a new method used by fishermen to circumvent a ban on killing sharks for their fins. According to an INTERPOL alert, fishermen are now leaving a band of skin to keep the fin attached to the spine when they kill sharks. This approach takes advantage of an apparent loophole in regulations governing the shark fin trade.
DNA tests reveal new dolphin species (photos)
(10/30/2013) With the help of DNA tests, scientists have declared a new dolphin species that dwells off the coast of northern Australia. The discovery was made after a team of researchers looked at the world's humpback dolphins (in the genus Sousa), which sport telltale humps just behind their dorsal fins. While long-known to science, the new, as-yet-unnamed species was previously lumped with other humpback dolphins in the Indo-Pacific region.
98% of marine fish headed for the aquarium trade die within a year in the Philippines
(10/22/2013) Almost all wild caught marine fish for the aquarium trade will die within a year of capture, according to WWF. Following months of interviews with Filipino marine exporters and hobbyists, WWF-Philippines have found that roughly 80% of all marine fish die before they are sold, and those that survive long enough to be bought by hobbyists are extremely likely to be dead in under a year.
The 'dead' ocean: eyewitness says overfishing has emptied the Pacific
(10/22/2013) An Australian sailor has described parts of the Pacific Ocean as "dead" because of severe overfishing, with his vessel having to repeatedly swerve debris for thousands of kilometers on a journey from Australia to Japan. Ivan MacFadyen told of his horror at the severe lack of marine life and copious amounts of rubbish witnessed on a yacht race between Melbourne and Osaka. He recently returned from the trip, which he previously completed 10 years ago.
Global warming could shift tropical rainfall
(10/21/2013) Ongoing burning of fossil fuels could flip which portion of the tropics receive more rainfall: the southern hemisphere or the northern. Currently, the northern hemisphere tropics is the wetter of the two, but why this is has long baffled scientists. Now, new research in Nature Geoscience has discovered that rainfall in the tropics is in part driven by massive ocean currents that travel back-and-forth between the Arctic and Antarctic, a process known as ocean overturning circulation.
Another 'sea-serpent' oarfish washes up in California
(10/20/2013) Another sea-serpent-like oarfish has been found dead along the coast in Southern California
California 'sea monster' is an oarfish
(10/16/2013) The dead "sea monster' spotted off the coast of Southern California on Sunday is actually an oarfish, a deepwater fish species that can reach a length of 55 feet (17 meters).
California celebrates its inaugural Pacific Leatherback Conservation Day with sobering reality
(10/15/2013) On an isolated beach in Bird’s Head Peninsula, Indonesia, a female leatherback turtle shuffles out of the ocean and onto the shore, ready to lay her eggs. Under the cover of night she excavates a hole in the sand, depositing anywhere from 80 to 100 eggs inside. Using her flippers she flicks sand over the eggs, hiding them from potential predators. Then, shuffling away, she returns to the turquoise waters ready to make an 8,500-mile journey across the Pacific Ocean to the California coast.
Russia charges non-violent activists with 'piracy' for protesting Arctic oil drilling
(10/07/2013) In what is being described by Greenpeace as an 'imaginary offense,' Russia has charged 30 people with piracy after activists protested against oil exploitation in the Arctic. The 30 charged included not only protestors, but a British journalist and Russian videographer who were on board Greenpeace's ship, the Arctic Sunrise, when it was stormed by the Russian military late last month.
Governments should respond to ocean acidification 'as urgently as they do to national security threats'
(10/03/2013) The oceans are more acidic now than they have been for at least 300m years, due to carbon dioxide emissions from burning fossil fuels, and a mass extinction of key species may already be almost inevitable as a result, leading marine scientists warned on Thursday. An international audit of the health of the oceans has found that overfishing and pollution are also contributing to the crisis, in a deadly combination of destructive forces that are imperiling marine life, on which billions of people depend for their nutrition and livelihood.
Sonar used by oil company caused mass whale stranding in Madagascar
(09/25/2013) An oil company's use of a high-frequency mapping sonar system was responsible for a mass whale stranding in northwest Madagascar in 2008, finds a new report.
Russian military raids Greenpeace ship, hold activists captive
(09/20/2013) Armed Russian military have stormed a Greenpeace ship protesting against oil exploitation in remote Arctic waters.
Shark overfishing hurts coral reefs
(09/20/2013) Overfishing for sharks is having detrimental effects on coral reefs, finds a new study published in the journal PLOS One.
Mesoamerican Reef needs more local support, says report
(09/13/2013) From massive hotel development through the agriculture industry, humans are destroying the second largest barrier reef in the world: the Mesoamerican Reef. Although global climate change and its effects on reefs via warming and acidification of coastal waters have made recent headlines, local human activities may destroy certain ecosystems before climate change has a chance to do it. The harmful effects of mining, agriculture, commercial development, and fishing in coastal regions have already damaged more than two-thirds of reefs across the Caribbean, in addition to worsening the negative effects of climate change.
Natural cooling cycle in Pacific may have slowed global warming...for now
(09/12/2013) Cooling waters in the tropical Pacific Ocean appear to be a major factor in dampening global warming in recent years, scientists said on Wednesday. Their work is a big step forward in helping to solve the greatest puzzle of current climate change research – why global average surface temperatures, while still on an upward trend, have risen more slowly in the past 10 to fifteen years than previously.
Video: scientists discover new walking shark species in Indonesia
(09/11/2013) A species of shark that uses its fins to 'walk' along the bottom of the ocean floor has been discovered off the coast of Indonesia. The shark, Hemiscyllium halmahera, uses its fins to wiggle along the seabed and forage for small fish and crustaceans, scientists from Conservation International said on Friday.
Finding a needle in a haystack: two new species of octocorals discovered in the Pacific Ocean
(09/04/2013) The vast expanse of the Earth's oceans makes finding a new species like finding a needle in a haystack. In fact, finding a needle in a haystack may be easier than finding a new species of octocoral in the Pacific Ocean. But Gary Williams with the California Academy of Sciences has recently found not only one but two new species, including a new genus of octocoral.
Are sea turtles responsible for lower fish catches in India?
(08/29/2013) Fishing communities on Agatti Island in Lakshwadeep, India, blame their reduced fish catch on green turtles; according to them, green turtles chomp their way through the seagrass beds lining the shallow reef waters that are essential for fish to breed. This leads some in the community to clandestinely kill sea turtles and destroy their nests.
Bad feedback: ocean acidification to worsen global warming
(08/28/2013) As if ocean acidification and climate change weren't troubling enough (both of which are caused by still-rising carbon emissions), new research published in Nature finds that ocean acidification will eventually exacerbate global warming, further raising the Earth's temperature.
Eighty sea turtles wash up dead on the coast of Guatemala
(08/27/2013) An assortment of marine animals and birds reside along the black volcanic sand beaches of Guatemala’s Pacific coast, but lately both residents and visitors on the southeast beaches of the country have observed a tragic event – the stranding of dead sea turtles. Eighty dead sea turtles have been recorded since the first week of July.
Whale shark mapping: scientists uncover global distribution for the largest fish in the world
(08/27/2013) Polka-dotted and striped. Massive but docile. That’s the whale shark for you - the largest fish and shark in the world. But despite being major tourist attractions, the lives of these awe-inspiring creatures of the ocean remain far from being demystified. However, a team of researchers from Australia may now have some answers to where these whale sharks (Rhinocodon typus) occur.
Google Earth presents fish-eye view of coral reefs
(08/20/2013) You can now visit up-close and personal some of the world's most imperiled ecosystems on Google Earth: coral reefs. The Google team is working with scientists to provide 360 degree panoramas, similar to Google street-view, to give armchair ecologists a chance to experience the most biodiverse ecosystems under the waves.
Climate change scattering marine species
(08/08/2013) Rising ocean temperatures are rearranging the biological make-up of our oceans, pushing species towards the poles by 7kms every year, as they chase the climates they can survive in, according to new research. The study, conducted by a working group of scientists from 17 different institutions, gathered data from seven different countries and found the warming oceans are causing marine species to alter their breeding, feeding and migration patterns.
U.S. bombs Great Barrier Reef, promises 'rapid recovery' of armaments
(07/23/2013) Four unarmed bombs dropped by the US military into the Great Barrier Reef Marine Park pose a low risk to wildlife and a joint mission will aim for their "rapid recovery", according to the government agency in charge of the reef. The Great Barrier Reef Marine Park Authority said two of the bombs are inert, containing concrete, while the other two were not armed, making the chance of detonation "extremely low".
Plan to preserve the world's 'last ocean' killed by Russia
(07/16/2013) As the most pristine marine ecosystem on the planet, Antarctica's Ross Sea has become dubbed the world's "last ocean." Home to an abundance of penguins, whales, orcas, seals, and massive fish, the Ross Sea has so far largely avoided the degradation that has impacted much of the world's other marine waters. However, a landmark proposal to protect the Ross Sea, as well as the coastline of East Antarctica, has failed today due to opposition by Russia.
Hurricane intensity, frequency to increase with climate change
(07/08/2013) Warmer ocean temperatures will increase the frequency and intensity of tropical cyclones, typhoons and hurricanes in "most locations" this century, concludes a new study based on simulations using six global climate models.
San Francisco seafood restaurants go sustainable
(07/02/2013) The Seafood Watch Program, first created by Monterey Bay Aquarium in the late 1990s, is arguably the best-known guide to sustainably-caught seafood in the U.S. Listing seafood choices in three categories—green (best choices), yellow (good alternatives), and red (avoid)—the guide informs consumers of the best options. However, it's one thing to create a well-respected guide, and another issues altogether to get producers and consumers to use it. But a newer partnership, the San Francisco Seafood Watch Alliance, is working to bridge this gap. Maggie Ostdahl of Aquarium of the Bay works with the Seafood Watch Restaurant program and restaurants across San Francisco—one of the best places in the country for seafood—to source sustainable seafood. Restaurant partners avoid seafood on the guide's red list.
Australia aims to end Japan's whaling
(06/27/2013) Australia is hoping to put a permanent end to Japan's annual slaughter of hundreds of whales in the Southern Ocean, in a landmark legal challenge that begins this week. Australia, a vocal opponent of Japan's annual "scientific" hunts in the Antarctic, says it is confident that the international court of justice (ICJ) in The Hague will outlaw the hunts at the end of a highly anticipated case that is due to start on Wednesday.
UN may downgrade Great Barrier Reef's heritage status due to Australia's inaction on threats
(06/17/2013) The federal government insists it is striving to avoid the Great Barrier Reef being listed 'in danger' ahead of a crunch UN meeting, after rejecting a Senate recommendation to block new port developments near the World Heritage ecosystem.
Ocean acidification pushing young oysters into 'death race'
(06/11/2013) Scientists have long known that ocean acidification is leading to a decline in Pacific oyster (Crassostrea gigas) in the U.S.'s Pacific Northwest region, but a new study in the American Geophysical Union shows exactly how the change is undercutting populations of these economically-important molluscs. Caused by carbon dioxide emissions, ocean acidification changes the very chemistry of marine waters by lowering pH levels; this has a number consequences including decreasing the availability of calcium carbonate, which oysters and other molluscs use to build shells.
Monster shark sparks talk of overfishing
(06/06/2013) A giant mako shark caught by a sports-fisherman Monday in California has spurred a conversation about declining shark populations worldwide, reports the Associated Press.
Manta ray tourism worth 28 times more than killing them for Traditional Chinese Medicine
(06/03/2013) A new study in the open access journal PLoS ONE estimates that manta rays are worth $140 million a year in tourism across 23 countries, significantly outweighing the worth of manta ray gill plates, which have become the newest craze in Traditional Chinese Medicine.
Whales teach each other new feeding behavior
(05/29/2013) Humpback whales (Megaptera novaeangliae), popularly known for their majestic and alluring underwater mating songs and acrobatic breaches, have shown that they can adapt to changing prey variability by passing on new hunting techniques to each other. According to new findings in the journal Science, a team of researchers have revealed the cultural spread of new hunting techniques through a population of humpback whales over the span of 27 years.
Famed bird reappears after 400,000 miles of flight
(05/22/2013) A migratory shorebird that has flown more than 400,000 miles has reappeared once again.
Biosphere conservation: monumental action is critical to avert global environmental crisis
(05/20/2013) Human-caused changes to our biosphere—the global total of the world's ecosystems—are now so great and alarmingly rapid that human lives and societies undoubtedly face epic challenges in the near future as our biosphere deteriorates, planetary boundaries are reached, and tipping points exceeded. We may survive, we may painfully adapt, but it is a fair bet that grave hardship, loss, and sacrifice lay ahead. The nature and extent of impacts among human populations hinges on how successfully we respond to the biosphere crisis with extraordinary leadership, balanced solutions applied at global scales, and unprecedented cooperation—or not.
Pacific islanders are the 'victims of industrial countries unable to control their carbon dioxide emissions'
(05/15/2013) With islands and atolls scattered across the ocean, the small Pacific island states are among those most exposed to the effects of global warming: increasing acidity and rising sea level, more frequent natural disasters and damage to coral reefs. These micro-states, home to about 10 million people, are already paying for the environmental irresponsibility of the great powers.
Industrialized fishing has forced seabirds to change what they eat
(05/14/2013) The bleached bones of seabirds are telling us a new story about the far-reaching impacts of industrial fisheries on today's oceans. Looking at the isotopes of 250 bones from Hawaiian petrels (Pterodroma sandwichensis), scientists have been able to reconstruct the birds' diets over the last 3,000 years. They found an unmistakable shift from big prey to small prey around 100 years ago, just when large, modern fisheries started scooping up fish at never before seen rates. The dietary shift shows that modern fisheries upended predator and prey relationships even in the ocean ocean and have possibly played a role in the decline of some seabirds.
New endangered list for ecosystems modeled after 'Red list' for species
(05/09/2013) The IUCN has unveiled the first iteration of its new Red List of Ecosystems, a ranking of habitats worldwide.
Scientists discover that marine animals disperse seagrass
(05/09/2013) Lesser known than coral reefs, marine seagrass ecosystems are rich in biodiversity and are powerhouses when it comes to sequestering carbon dioxide. Yet, much remains unknown about the ecology of seagrass beds, including detailed information on how seagrass spread their seeds and colonize new area. Now a recent study in Marine Ecology Progress Series documents that several species of marine animal are key to dispersing seagrass, overturning the assumption that seagrass was largely dispersed by abiotic methods (such as wind and waves).
Featured video: saving sea turtles in Mexico's Magdalena Bay
(05/09/2013) A new short film, Viva la tortuga documents the struggle to save loggerhead and green sea turtles in Magdalena Bay, Mexico. Once a region for a massive sea turtle meat market, the turtles now face a new threat: bycatch. Loggerhead sea turtles are drowning in bottom-set gillnets, unable to escape from the nets once entangled. The issue has even raises threats of trade embargoes from the U.S.
Are seagulls killing whales in Patagonia?
(05/08/2013) It sounds ludicrous, but it could just be true: scientists say seagulls may be responsible for hundreds of southern right whale moralities off the Argentine coastline. Since 2003, scientists have documented the deaths of 605 southern right whales (Eubalaena australis) near Península Valdés which the whales use as a nursery. Notably, 88 percent of these were newborn calves. The death rate is so high that researchers now fear for the whales' long-term survival.
Munching on marine plastic kills sperm whale
(05/07/2013) What do children's toys, balloons, mattresses and plastic bags have in common? They can, along with more non-biodegradable pollutants, be found in the belly of a sperm whale, the topic of a new study in the Marine Pollution Bulletin. The same whale that swallowed Jonah from the Bible, Geppetto from Collodi's Pinocchio, and the crew of the Pequod from Melville's Moby-Dick is now swallowing trash from the Spanish-Mediterranean coast, and in the Strait of Gibraltar.
