NRDC Challenges Navy's Plan to Utilize Dangerous Sonar in More Than 70% of World's Oceans

:: October 18, 2012



Today, NRDC sued the U.S. Navy and the government agency charged with protecting marine mammals from the Navy’s harmful use of sonar.  Both the Navy and the National Marine Fisheries Service (“NMFS”) have a responsibility to manage, conserve, and protect living marine resources, like whales and dolphins, particularly those protected by the Endangered Species Act.  Unfortunately, the Navy and NMFS failed to meet their obligation to protect whales and other marine life from the harmful impacts of low-frequency active sonar (“LFA”), when they authorized the deployment of LFA in 70-75 % of the World’s Oceans without instituting adequate protective measures...

Petition | California Coastal Commission: Protect Whales~ Stop Seismic Testing off the Coast of Central California!


Pacific Gas & Electric (PG&E) is posed to conduct seismic testing in a grid pattern over a large area off the Central Coast of California from Cambria to the Santa Maria River. Tests could begin as early as September 2012 and last until the end of the year. The research ship would emit blasts of very loud noise into the ocean. Streamers four or five miles long would be towed behind the vessel, which would pick up the sound waves as they penetrate several miles into the Earth’s crust and reverberate back to the surface. 
Tests would last for 24 hours and would kill or injure marine mammals, including whales, dolphins, porpoises, seals and otters. A deaf marine mammal is a dead one as this is the sense they rely on to communicate, navigate and find food. Seabirds and other species such as endangered sea turtles, could be affected as well, with little or no way of mitigating the impacts. Great potential harm is highly possible to the small population of harbor porpoises in the Morro Bay area. They are most sensitive to loud man-made sound and the mammal most vulnerable to habitat abandonment and to hearing loss. 
PG&E’s position is that the tests are necessary to map the ocean floor so geologists can better understand the earthquake faults near Diablo Canyon nuclear power plant, close to San Luis Obispo, California. Earthquake faults were known at the time the plant was built. PG&E states these tests are essential in the aftermath of the Fukushima earthquake and subsequent tsunami, and the potential for a nuclear disaster. 
If an earthquake happened within the near future, what could be done to ensure that the Diablo Canyon plant would not have a meltdown? How will these tests prevent that scenario? The nuclear plant was constructed knowing that faults were nearby and that earthquakes were a potential danger. Wouldn’t it make more sense to spend the millions of dollars the tests will cost to instead begin plans to shut down the plant and find ways to shift to safe energy? Wouldn’t this be wiser than destroying untold numbers of animals within a Marine Protected Area, particularly when the necessary safeguards have not been implemented?

BP Oil Spill Cover Up in 2008 May Have Led To Gulf Spil


gather | April 20, 2012

Years of investigative reporting have uncovered what appears to be a trail of information showing a BP oil spill cover up on a rig off the coast of Azerbaijan in the Caspian Sea in 2008.


EcoWatch reveals shocking information of a BP cover-up of a blow-out prior to the deadly Deepwater Horizon explosion in the Gulf. Special report from the Caspian sea. for Ecowatch.org by investigative reporter Greg Palast. BP Blow-out Cover-Up - EcoWatch.org - YouTube

The bombshell aspect of this EcoWatch.org report from Greg Palast is not necessarily the cover-up, but the suggestion that the Caspian Sea blow-out on the Central Azeri platform in 2008 was due to the same cost-saving practice of using "quick-dry" cement to plug holes in well caps.

That same practice is largely believed to have been the cause, or at least a contributing factor, to the Deepwater Horizon blowout BP suffered two years ago today in the Gulf of Mexico resulting in 11 deaths, 17 injuries and untold environmental and economic damage for the Gulf Coast of the U.S. This excerpt from Palast's report on this alleged BP oil spill cover up explains the connection: "One cause of the blow-outs was the same in both cases: the use of a money-saving technique—plugging holes with "quick-dry" cement. By hiding the disastrous failure of its penny-pinching cement process in 2008, BP was able to continue to use the dangerous methods in the Gulf of Mexico—causing the worst oil spill in U.S. history."

Palast's investigation relies on confidential informants familiar with the Caspian Sea blow-out, as well as shoe-leather efforts to explore the BP oil terminal in Azerbaijan, which resulted in the arrests of Palast, his crew, and the "disappearing" of men who were willing to talk about the 2008 blow-out...

Some Gulf Dolphins Severely Ill | Gulf Spill



Barataria Bay


Following the Deepwater Horizon oil spill, numerous dolphins were documented encountering oil, such as those in this photo from July 2010.

Bottlenose dolphins in Barataria Bay, Louisiana, are showing signs of severe ill health, according to NOAA marine mammal biologists and their local, state, federal and other research partners.

Barataria Bay, located in the northern Gulf of Mexico, received heavy and prolonged exposure to oil during the Deepwater Horizon oil spill.

Based on comprehensive physicals of 32 live dolphins from Barataria Bay in the summer of 2011, preliminary results show that many of the dolphins in the study are underweight, anemic, have low blood sugar and/or some symptoms of liver and lung disease. Nearly half also have abnormally low levels of the hormones that help with stress response, metabolism and immune function.



a dolphin called Y12


Aug 2011: Veterinarians collect a urine sample from Y12, a 16-year-old adult male bottlenose dolphin caught near Grand Isle, LA. Y12’s health evaluation determined that he was significantly underweight, anemic, and had indications of liver and lung disease. After the evaluation and attachment of VHF and satellite-linked tags, Y12 was released.


Body mass index (BMI), a function of mass and length, is plotted against dolphin age. Solid lines classify BMI as normal (between lines) or underweight (below lower line). Blue squares represent male dolphins sampled in Sarasota Bay, FL; red circles represent male dolphins sampled in Barataria Bay and surrounding waters.

Researchers fear that some of the study dolphins are in such poor health that they will not survive. One of these dolphins, which was last observed and studied in late 2011, was found dead in January 2012.


Jan 2012: The carcass of Y12, one of the Barataria Bay dolphins closely studied by NRDA researchers, was recovered on Grand Isle Beach, January 31, 2012. The visible ribs, prominent vertebral processes and depressions along the back are signs of extreme emaciation. A necropsy was performed and samples were collected to help determine cause of death and potential contributing factors.

NOAA and its local, state and federal partners started the Barataria Bay dolphin study in 2011 as part of the Natural Resource Damage Assessment (NRDA), the process for studying the effects of the Deepwater Horizon oil spill.

NOAA is sharing the preliminary results from the study so that stranding responders and veterinarians can better care for live stranded dolphins and look for similar health conditions.


Investigation of Dolphin Strandings in the Northern Gulf Continues


Number of strandings by region compared to 10 year historical average with 95% confidence limits (the historical averages include data from previous Gulf of Mexico UMEs). The Florida Panhandle includes Franklin through Escambia counties, and the Florida west coast includes Wakulla through Monroe counties.

Since February 2010, more than 675 dolphins have stranded in the northern Gulf of Mexico (Franklin County, Florida, to the Louisiana/Texas border)–a much higher rate than the usual average of 74 dolphins per year, prompting NOAA to declare an Unusual Mortality Event (UME) and investigate the cause of death for as many of the dolphins as possible. The vast majority of stranded dolphins have been found dead; however, 33 have stranded alive and seven have been taken to facilities for rehabilitation.

In the spring, it is typical to see some newborn, fetal and stillborn dolphins strand, and there has been an increase in strandings of this younger age class during this UME in 2010 and 2011. Yet all age classes continue to strand at high levels. NOAA is working with a team of marine mammal health experts to investigate the factors that may be contributing to the dolphin mortalities.


Gulf Seafood Safety

Since the 2010 oil spill, the Food and Drug Administration, NOAA and the Gulf Coast states have used an agreed-upon protocol to test seafood and ensure that it is free of harmful oil and dispersant residues. NOAA opened federal waters to fishing after extensive testing, and the Gulf states continue to use the protocol to routinely test finfish and shellfish to ensure all seafood reaching the consumer is safe. Some waters in the northern Barataria Basin, a larger area that includes Barataria Bay, remain closed to commercial fishing, as visible oil is still present along the shoreline where the closures are in place. The joint protocol directs seafood safety testing to begin only after visible oil is gone.
NOAA and its state and federal partners are researching multiple ways Gulf dolphins may have been exposed to oil, including through ingestion, inhalation or externally. Dolphins could have routinely ingested oil from sediments or water while feeding or by eating whole fish, including internal organs and fluids such as liver and bile, which can harbor chemical contaminants. These are not likely routes of exposure for most people.

Sentinels of the Seas | pollution & dolphin immune system dysfunction and disease




Bottlenose dolphins are a beloved Florida icon. But, recent studies show disturbing signs of immune system dysfunction and disease plaguing this charismatic mammal. These problems might be linked to legacy contaminants and other pollutants which bio-accumulate up the ocean food chain. For decades, toxic chemicals have made their way into the oceans, leaving fish and marine mammals vulnerable.

As sentinels of ecosystem health, dolphins potentially hold clues to environmental hazards that could impact humans. Changing Seas visits the world’s longest running dolphin research program and other marine mammal centers for a better understanding of the silent threats lurking beneath the waves.

BP Oil Still Tars the Gulf | The Progressive

For many Americans, the story of the BP disaster began on April 20, 2010, and ended on August 15 of that year, when the Obama Administration declared that “the majority of the oil is gone,” though the opposite was true.

For those on the Gulf Coast, the disaster remains, and life continues to be measured in terms of “before” and “after” the BP oil spill. They are tired of it all: BP, the government, the lies and the lawyers, the hardship and the illness, the oil on the beach and in the water, the dead dolphins and the disfigured fish, the ever-shrinking hauls of oysters, crab, and shrimp, and the rest of the nation’s cold shoulder. They still don’t know the answers to many life-and-death questions. But they keep going, hoping for life to return to the way it was before.

By July 9, 2011, roughly 491 miles (790 kilometers) of coastline in Louisiana, Mississippi, Alabama and Florida remained contaminated by BP oil, according to a NOAA spokesperson. In October 2011, a NOAA report stated that dolphins and whales continue to die at twice the normal rate.
The Deepwater Horizon oil spill (also referred to as the BP oil spill, the Gulf of Mexico oil spill, the BP oil disaster, or the Macondo blowout)[5][6][7] is an oil spill in the Gulf of Mexico which flowed unabated for three months in 2010. It is the largest accidental marine oil spill in the history of the petroleum industry.[8][9][10] The spill stemmed from a sea-floor oil gusher that resulted from the April 20, 2010, explosion of Deepwater Horizon, which drilled on the BP-operated Macondo Prospect. The explosion killed 11 men working on the platform and injured 17 others.[11] On July 15, 2010, the leak was stopped by capping the gushing wellhead,[12] after it had released about 4.9 million barrels (780,000 m3) of crude oil.[3] An estimated 53,000 barrels per day (8,400 m3/d) escaped from the well just before it was capped.[10] It is believed that the daily flow rate diminished over time, starting at about 62,000 barrels per day (9,900 m3/d) and decreasing as the reservoir of hydrocarbons feeding the gusher was gradually depleted.[10] On September 19, 2010, the relief well process was successfully completed, and the federal government declared the well "effectively dead".[13] In August 2011, oil and oil sheen covering several square miles of water were reported surfacing not far from BP’s Macondo well.[14] Scientific analysis confirmed the oil is a chemical match for Macondo 252.[15][16] The Coast Guard said the oil was too dispersed to recover.[17]

The spill caused extensive damage to marine and wildlife habitats and to the Gulf's fishing and tourism industries.[18][19] Skimmer ships, floating containment booms, anchored barriers, sand-filled barricades along shorelines, and dispersants were used in an attempt to protect hundreds of miles of beaches, wetlands, and estuaries from the spreading oil. Scientists also reported immense underwater plumes of dissolved oil not visible at the surface[20] as well as an 80-square-mile (210 km²) "kill zone" surrounding the blown well.[21] In late November 2010, 4,200 square miles (11,000 km²) of the Gulf were re-closed to shrimping after tar balls were found in shrimpers' nets.[22] The amount of Louisiana shoreline affected by oil grew from 287 miles (462 km) in July to 320 miles (510 km) in late November 2010.[23] In January 2011, an oil spill commissioner reported that tar balls continue to wash up, oil sheen trails are seen in the wake of fishing boats, wetlands marsh grass remains fouled and dying, and crude oil lies offshore in deep water and in fine silts and sands onshore.[24] A research team found oil on the bottom of the seafloor in late February 2011 that did not seem to be degrading.[25] On May 26, 2011, the Louisiana Department of Environmental Quality extended the state of emergency related to the oil spill.[26] By July 9, 2011, roughly 491 miles (790 kilometers) of coastline in Louisiana, Mississippi, Alabama and Florida remained contaminated by BP oil, according to a NOAA spokesperson.[27] In October 2011, a NOAA report stated that dolphins and whales continue to die at twice the normal rate.[28]


The oil slick as seen from space by NASA's Terra satellite on May 24, 2010

In January 2011 the White House oil spill commission released its final report on the causes of the oil spill. They blamed BP and its partners for making a series of cost-cutting decisions and the lack of a system to ensure well safety. They also concluded that the spill was not an isolated incident caused by "rogue industry or government officials", but that "The root causes are systemic and, absent significant reform in both industry practices and government policies, might well recur".[29] After its own internal probe, BP admitted that it made mistakes which led to the Gulf of Mexico oil spill.[30] In June 2010 BP set up a $20 billion fund to compensate victims of the oil spill. To July 2011, the fund has paid $4.7 billion to 198,475 claimants. In all, the fund has nearly 1 million claims and continues to receive thousands of claims each week.[31]

In September 2011, the U.S. government published its final investigative report on the accident. In essence, that report states that the main cause was the defective cement job, and Halliburton, BP and Transocean were, in different ways, responsible for the accident.[32]

The NOAA Deepwater Horizon Archive serves as a centralized location online for much of the information NOAA gathered during the Deepwater Horizon/BP oil spill response and restoration activities.

As the nation's experts on oceanic and atmospheric science and the lead science agency for oil spills, NOAA was on the scene of the Deepwater Horizon/BP oil spill since the earliest moments of the crisis. Our scientists used data from satellites, aircraft, ships, buoys, and gliders to collect and provide mission-critical information to guide the emergency response to the spill and now the long-term restoration of the Gulf Coast.

Watch Ocean Giants - Preview on PBS. See more from Nature.


i just learned that blue whales live for 2 centuries - the few remaining old ones remember the really bad days, even have old harpoons still in them. bigger than dinosaurs... living here and now on earth with us today... - problem is global warming is likely to disrupt their food supply so badly that something that huge won't be able to survive.

Whales and dolphins conjure a deep sense of wonder in us that’s hard to explain. From the Arctic to the Amazon, this groundbreaking three-part series goes on a global expedition with world-renowned underwater cameramen, Doug Allen (Planet Earth) and Didier Noirot (Jacques Cousteau’s cameraman), as they capture spellbinding footage of these marine mammals. Ocean Giants looks at how cetaceans hunt, mate, and communicate, and follows scientists as they strive to uncover new insights about these animals.

Watch Songs of the Humpbacks on PBS. See more from Nature.


The first hour, Giant Lives, enters the world of the great whales. In the Arctic, giant bowhead whales survive the freezing cold wrapped in fifty tons of insulating blubber two-feet thick, making them the fattest animals on the planet. But the biggest animal on the planet is the blue whale. Measuring a hundred feet long, and weighing in at 200 tons, it is double the size of the largest dinosaur.

The second hour, Deep Thinkers, explores the cognitive and emotional lives of dolphins and whales. Like us, cetaceans have special brain cells, spindle cells, that are associated with communication, emotion, and heightened social sensitivity. These cells were once thought to be unique to us, but research is now showing that whales and dolphins may have up to three times more spindle cells than humans.

Marine mammals’ extrasensory perceptions and communication skills are the focus of Voices of the Sea, the final hour of the series. Whales and dolphins depend on sound to function in their ocean home. They use ultrasound to see inside other creatures, clicks and whistles to speak, and echolocation to navigate and hunt in the pitch-black depths.

Join PBS Nature, as it dives into the world of whales and dolphins, and reveals the secrets of their intimate lives like never before. Ocean Giants premieres on Wednesday, February 22, 2012 at 8/7 c (check local listings).

The U.S. Navy is experimenting with a long range underwater sonar system which is to be used to detect the presence and position of submarines deep in the oceans of the world. It uses a low frequency signal that can travel great distances and presumeably bounce off targets that are hundreds of meters below the ocean surface.

Navy Sonar & Whales

Navy sonar harms whales and dolphins. Check out this video and hear what it sounds like, and see what it does to these marine mammals. Earthjustice is working to get the Navy to use their sonar in places where it won't harm whales and dolphins.

The incident recorded in this video occurred in Puget Sound in May 2003. It was investigated by the National Marine Fisheries Service, Office of Protected Resources, who filed a report.

Video: Orca and Navy Sonar | Earthjustice

BACKGROUND INFORMATION:
A whale's keen sense of hearing is vital in every aspect of its life history, including foraging for food, finding mates, bonding with offspring, communicating with other members of their species, navigating through lightless waters and avoiding predators.
Experts agree that exposure to sonar blasts can cause serious injury or death from hemorrhages or other tissue trauma. Whales can also suffer from temporary and permanent hearing loss, displacement from preferred habitat, and disruption of feeding, breeding, communication and other behaviors essential to survival.
The use of military sonar has been associated with whale strandings in Greece (1996), the Bahamas (2000), Madeira (2000), Vieques (1998, 2002), the Canary Islands (2002, 2004), the northwest coast of the U.S. (2003), Kaua'i (2004) and Spain (2006).


RELATED EARTHJUSTICE LITIGATION


Earthjustice Attorney Steve Mashuda discusses this case in an interview with San Francisco Bay Area NBC News affiliate KNTV.

Navy Sonar and Marine Mammals: On January 26, 2012, a coalition of conservation and American Indian groups sued the National Marine Fisheries Service for failing to protect thousands of whales, dolphins, porpoises, seals, and sea lions from U.S. Navy warfare training exercises along the coasts of California, Oregon, and Washington. In late 2010, NMFS gave the Navy a permit for five years of expanded naval activity that will harm or "take" marine mammals and other sealife. The permit allows the Navy to conduct increased training exercises that can harm marine mammals and disrupt their migration, nursing, breeding, or feeding, primarily as a result of harassment through exposure to the use of sonar.

North Atlantic Right Whales: In 2010, conservation groups challenged the U.S. Navy's decision to build a $100 million Undersea Warfare Training Range 50 miles east of Jacksonville, FL, next to the only known calving ground for the critically endangered North Atlantic right whale. The warfare training grounds would include a system of approximately 300 underwater "sonar nodes" connected by cable to a landside facility some 50 nautical miles away. Scientists believe that the loss of even one right whale from non-natural causes could jeopardize the future of the species.

Navy Sonar and Hawaiian Humpback Whales: In 2008, Hawai'i federal district Judge David A. Ezra found that the Navy violated federal law and enjoined it from carrying out its undersea warfare exercises in Hawai'i's waters without adhering to additional mitigation measures to protect marine mammals. Earthjustice had filed suit on behalf of the Ocean Mammal Institute, the Animal Welfare Institute, KAHEA: The Hawaiian-Environmental Alliance, the Center for Biological Diversity and the Surfrider Foundation's Kaua'i Chapter.

Endangered Species Protections for Southern Residents: In 2005, Earthjustice successfully argued that the Southern Resident orcas in Washington State's Puget Sound deserve protection under the Endangered Species Act, resulting in new safeguards for the orcas, including the creation of a binding recovery plan, protection for the whales' critical habitat, and assurances that all federal projects will protect the whales before the projects can proceed.

Navy Training Blasts Marine Mammals with Harmful Sonar | Earthjustice

January 26, 2012
San Francisco, CA - A coalition of conservation and American Indian groups today sued the National Marine Fisheries Service (NMFS) for failing to protect thousands of whales, dolphins, porpoises, seals, and sea lions from U.S. Navy warfare training exercises along the coasts of California, Oregon, and Washington.

Earthjustice, representing InterTribal Sinkyone Wilderness Council, Center for Biological Diversity, Friends of the Earth, Friends of the San Juans, Natural Resources Defense Council (NRDC), and People For Puget Sound, today filed a lawsuit in U.S. District Court for the District of Northern California challenging NMFS’s approval of the Navy’s training activities in its Northwest Training Range Complex. The lawsuit calls on NMFS to mitigate anticipated harm to marine mammals and biologically critical areas within the training range that stretches from Northern California to the Canadian border.
“These training exercises will harm dozens of protected species of marine mammals—Southern Resident killer whales, blue whales, humpback whales, dolphins, and porpoises—through the use of high-intensity mid-frequency sonar,” said Steve Mashuda, an Earthjustice attorney representing the groups. “The Fisheries Service fell down on the job and failed to require the Navy to take reasonable and effective actions to protect them.”
The Navy uses a vast area of the West Coast for training activities including anti-submarine warfare exercises involving tracking aircraft and sonar; surface-to-air gunnery and missile exercises; air-to-surface bombing exercises; sink exercises; and extensive testing for several new weapons systems... > more
