It's not just the oil that will taint the fish, oysters and shellfish. It's also the chemical oil dispersants, as Spike is referring to. BP has been using Corexit 9500.

After this is over I am willing to bet that there will be a moratorium on commercial fishing (as well as sport fishing) until the sea life gets back to normal.

With respects to toxic chemicals found in the fish, oysters and shellfish I'm going to guess that it will be quite a while before I'll feel it's safe to eat it. I'm not interested in being someone's case study. Neither my government nor BP (or any other oil company) have my best interest at heart and I trust neither when it comes to my health.

Sorry Val, I agree with you but using the EPA as a source after your last sentence was kind of funny. ;)

It doesn't look like his response indicates his personal view on that part.
Seems he was merely pointing out a kind of oxymoron there.

as another side note...
there may also be some outsourced sources also there.

Perhaps Myrlin likes the FDA and USDA and just not the EPA?

Perhaps Mirlyn simply questions studies which are based on a few years of research. Nobody knows what they do long term. Same goes for prescription meds. Could be harmless. We just don't know.

Gulf Oil Spill Is Vanishing Fast

It seems that it is as we stated -- the spill would mostly clean itself up. Even the NYT admits that the enviros were not correct in their dire predictions and the length of time the spill would continue to destroy the Earth.

The article is below.

A good interview with an environmental sciences Professor Edward B. Overton can be heard HERE.

On the Surface, Gulf Oil Spill Is Vanishing Fast; Concerns Stay


By JUSTIN GILLIS and CAMPBELL ROBERTSON
Published: July 27, 2010

The oil slick in the Gulf of Mexico appears to be dissolving far more rapidly than anyone expected, a piece of good news that raises tricky new questions about how fast the government should scale back its response to the Deepwater Horizon disaster.

The immense patches of surface oil that covered thousands of square miles of the gulf after the April 20 oil rig explosion are largely gone, though sightings of tar balls and emulsified oil continue here and there.

Reporters flying over the area Sunday spotted only a few patches of sheen and an occasional streak of thicker oil, and radar images taken since then suggest that these few remaining patches are quickly breaking down in the warm surface waters of the gulf.

John Amos, president of SkyTruth, an environmental advocacy group that sharply criticized the early, low estimates of the size of the BP leak, noted that no oil had gushed from the well for nearly two weeks.

“Oil has a finite life span at the surface,” Mr. Amos said Tuesday, after examining fresh radar images of the slick. “At this point, that oil slick is really starting to dissipate pretty rapidly.”

The dissolution of the slick should reduce the risk of oil killing more animals or hitting shorelines. But it does not end the many problems and scientific uncertainties associated with the spill, and federal leaders emphasized this week that they had no intention of walking away from those problems any time soon.

The effect on sea life of the large amounts of oil that dissolved below the surface is still a mystery. Two preliminary government reports on that issue have found concentrations of toxic compounds in the deep sea to be low, but the reports left many questions, especially regarding an apparent decline in oxygen levels in the water.

And understanding the effects of the spill on the shorelines that were hit, including Louisiana’s coastal marshes, is expected to occupy scientists for years. Fishermen along the coast are deeply skeptical of any declarations of success, expressing concern about the long-term effects of the chemical dispersants used to combat the spill and of the submerged oil, particularly on shrimp and crab larvae that are the foundation of future fishing seasons.

After 86 days of oil gushing into the gulf, the leak was finally stopped on July 15, when BP managed to install a tight-fitting cap on the well a mile below the sea floor, then gradually closed a series of valves. Still, the well has not been permanently sealed. Until that step is completed in several weeks, the risk remains that the leak will resume.

Scientists said the rapid dissipation of the surface oil was probably due to a combination of factors. The gulf has an immense natural capacity to break down oil, which leaks into it at a steady rate from thousands of natural seeps. Though none of the seeps is anywhere near the size of the Deepwater Horizon leak, they do mean that the gulf is swarming with bacteria that can eat oil.

The winds from two storms that blew through the gulf in recent weeks, including a storm over the weekend that disintegrated before making landfall, also appear to have contributed to a rapid dispersion of the oil. Then there was the response mounted by BP and the government, the largest in history, involving more than 4,000 boats attacking the oil with skimming equipment, controlled surface burns and other tactics.

Some of the compounds in the oil evaporate, reducing their impact on the environment. Jeffrey W. Short, a former government scientist who studied oil spills and now works for the environmental advocacy group Oceana, said that as much as 40 percent of the oil in the gulf might have simply evaporated once it reached the surface.

An unknown percentage of the oil would have been eaten by bacteria, essentially rendering the compounds harmless and incorporating them into the food chain. But other components of the oil have most likely turned into floating tar balls that could continue to gum up beaches and marshes, and may represent a continuing threat to some sea life. A three-mile by four-mile band of tar balls was discovered off the Louisiana coast on Tuesday.

“Less oil on the surface does not mean that there isn’t oil beneath the surface, however, or that our beaches and marshes are not still at risk,” Jane Lubchenco, administrator of the National Oceanic and Atmospheric Administration, said in a briefing on Tuesday. “We are extremely concerned about the short-term and long-term impacts to the gulf ecosystem.”

Thad W. Allen, the retired Coast Guard admiral who leads the government’s response, has emphasized that boats are still skimming some oil at the surface. Admiral Allen said the risk of shoreline oiling might continue for at least several more weeks.

“While we would all like to see the area come back as quickly as it can,” he said, “I think we all need to understand that we, at least in the history of this country, we’ve never put this much oil into the water. And we need to take this very seriously.”



Still, it is becoming clear that the Obama administration, in conjunction with BP, will soon have to make decisions about how quickly to begin scaling down the large-scale — and expensive — response effort. That is a touchy issue, and not just for environmental reasons.

The response itself has become the principal livelihood for thousands of fishermen and other workers whose lives were upended by the oil spill. More than 1,400 fishing boats and other vessels have been hired to help deploy coastal barriers and perform other cleanup tasks. Those fishermen are unconvinced that the gradual disappearance of oil on the surface means they will be able to return to work soon.

“Surface is one thing; you know that’s going to dissipate and all,” said Mickey Johnson, who owns a shrimp boat in Bayou La Batre, Ala., pointing out that shrimpers trawl near the sea floor.

“Our whole big concern has always been the bottom,” Mr. Johnson said.

The scientific picture of what has happened at the bottom of the gulf remains murky, though Dr. Lubchenco said in Tuesday’s briefing that federal scientists had determined that the oil was primarily in the water column and not sitting on the sea floor.

States have been pushing the federal authorities to move quickly to reopen gulf waters to commercial fishing; through most of the spill, about a third of the United States part of the gulf has been closed. The Food and Drug Administration is trying to speed its testing, while promising continued diligence to be sure no tainted seafood gets to market.

Even if the seafood of the gulf is deemed safe by the authorities, resistance to buying it may linger among the public, an uncertainty that defies measurement and is on the minds of residents along the entire Gulf Coast.

“How do we get people to buy our food again?” Mr. Johnson asked.

While leaders on the Gulf Coast would welcome moves by the federal government that could put residents back to work, they are also wary of any premature declaration of victory. Officials in Grand Isle, La., met with the Coast Guard after the well had been capped to insist that no response equipment be removed until six weeks had passed.

Rear Adm. Paul F. Zukunft of the Coast Guard, coordinator of the response on the scene, said any decisions about scaling down the effort would be made only by consensus, and only after an analysis of the continuing threat from oil in each region of the gulf.

“I think it’s going to happen one day at a time,” Admiral Zukunft said.

John Collins Rudolf contributed reporting.

Jim, this article is really only about the oil that was still on the surface of the gulf waters and not what spread to land.

From your article...
"And understanding the effects of the spill on the shorelines that were hit, including Louisiana’s coastal marshes, is expected to occupy scientists for years. Fishermen along the coast are deeply skeptical of any declarations of success, expressing concern about the long-term effects of the chemical dispersants used to combat the spill and of the submerged oil, particularly on shrimp and crab larvae that are the foundation of future fishing seasons."

Don't dismiss the work that people did to save the coastline. Nature didn't clean all that up by itself and it's still there. Some of that oil made it's way into the marshes and onto the beaches already.

The oil isn't gone, it's just spread thinner over a larger area.

NYT admits that the enviros were not correct

Funny, that's not in the article.

the spill would mostly clean itself up.

It's not mostly cleaning itself up. There's a shit ton of people working on it and a massive amount of oil still there.

Not to mention the burn offs, the oil dispersal chemicals being used, etc.

Disaster that never was: Why claims that BP created history's worst oil spill may be the most cynical spin campaign ever

By David Jones
Last updated at 10:31 PM on 6th August 2010

The warm, white sand stretches for miles as clean and flat as a freshly laundered bed sheet.

The turquoise sea is so clear that I can see silvery fish playing around my toes as I take a cooling paddle.

If there is any more pristine resort in which to spend a summer holiday than Pensacola Beach, on the Gulf Coast of Florida, I would like to find it.

And yet, at a time of year when usually there is barely room to unfold a deckchair, the shore is eerily deserted.

Ask Pensacola’s fretfully quiet seafront traders why the tourists have all stayed away and they angrily recall one chaotic day back in late June.

Then, hungry for dramatic TV footage to support Barack Obama’s announcement, that the BP - or, as he preferred, ‘British Petroleum’ - oil spill was ‘the worst environmental disaster America has ever faced’, news networks descended on their town.

They quickly found what they were looking for: shocking images of Pensacola’s famously white beaches thickly-coated with sticky, black crude oil and apparently beyond salvation.

The apocalyptic message was reinforced in doom-laden interviews with locals. ‘It’s damn near biblical. This place is done for!’ lamented 36-year-old Kevin Reed, whose family have swum and sunbathed in the area for generations.

His anguish was understandable.

Yet, as I saw this week, nothing could be further from the truth. Strolling along the beach for an hour, I found just one, pea-sized tar-ball which crumbled to nothing between my fingers.

When, as a young boy, I played on Morecambe beach in Lancashire, worse things often washed up from the nearby ICI refinery.

Moreover, if the U.S. TV news crews had returned just three days after their original visit, they would have seen that the black morass had already been removed by some of the 20,000 clean-up workers hired by BP.

The workers are still there - only now they are using toothbrushes to sift out even the tiniest particles of oil.

But, of course, after a ‘catastrophic’ oil spill, a spotless beach doesn’t make dramatic viewing and who wants to know?

Certainly not the politicians, nor the green-lobby tub-thumpers, nor the compensation claimants and their mega-bucks lawyers.

Until this week, it didn’t fit with the White House’s British-bashing script, either. In recent days, though, we have witnessed an extraordinary U-turn in America’s attitude towards the great spill.

It began when a respected Time magazine environmental writer voiced the near-heretical proposition: that the effects of the Deepwater Horizon disaster on April 20 had been massively hyped.

His article was largely based on the opinions of Professor Ivan van Heerden, a brilliant but controversial marine scientist fired by Louisiana State University after publishing a book about Hurricane Katrina that said cataclysmic flooding was inevitable because the protection given to the coast was wholly inadequate.

He said: ‘There is just no data to suggest this is an environmental disaster - although BP lied about the size of the oil spill, we’re not seeing catastrophic impacts.’

Emboldened by the academic’s willingness to go against the accepted wisdom, other leading scientists have concurred, with similar views being expressed in influential U.S. newspapers such as the New York Times and Washington Post.

It was against this background that the Obama administration made its own dramatic U-turn this week.

In a humiliating climb-down, it conceded in an official report from the U.S. National Oceanic and Atmospheric Administration (NOAA) that the ‘vast majority’ of the spilled oil had already gone.

The rest, it said, had probably diluted and didn’t appear to pose much of a threat.

According to 25 leading U.S. government and independent scientists, the feared catastrophe to the coast’s fragile ecosystem had been averted.

The cynical spin from Washington suggested that Obama had successfully browbeaten BP into mopping up its mess - with Mother Nature lending a helping hand.

What more suitably upbeat message with which to mark the president’s 49th birthday?

So were the doom-mongers really so wrong, and if so, then why?

Why was one of Britain’s greatest companies so demonised? Why did America’s politicians and president so hysterically over-react?

In order to get to the bottom of one of the most shameful buck-passing operations in recent times, I spent this week with those involved at the sharp end.

How BP's Gulf of Mexico oil spill could actually lead to an increase in fish stocks

By Mail Foreign Service
Last updated at 11:42 AM on 5th August 2010

The massive BP oil spill could lead to increased fish stocks and improvements in biodiversity in the Gulf of Mexico, according to marine expert.

The White House admitted yesterday that the leak was less catastrophic than previously thought.

In a humiliating climbdown, the Obama administration conceded the 'vast majority' of the oil that gushed into the ocean from the ruptured well has already gone.

The rest, it says, is probably so diluted, it does not appear to pose much of a threat.

The extraordinary change of tune came after government scientists concluded, much to President Obama's embarrassment, that three-quarters of the leaked oil has evaporated, dispersed, been burned off or been contained.

Now a leading marine scientist has said the culmination of a fishing ban in the region and swiftly dispersing oil could lead to fish stocks improving.

'The oil may have killed fewer fish than the fisherman would have done,' Martin Preston, senior lecturer in ocean sciences at the University of Liverpool, told the Times.

'Stocks may look better next year but we won't know until then. The big imponderable is the effect of the toxicity of the oil on the larval stage of the fish.'

And he said though young fish were at the mercy of the spill, some of the more mature specimens would have survived by swimming to less polluted areas.

'Dead fish float and there have been no reports of large numbers of dead fish floating around,' he said.

Dr Preston, who studied the impact of a bigger spill in the Persian Gulf after the 1991 Gulf War, said that incident had led to bigger catches in the following years.

'When they got fishing again after the war, they had more and bigger fish because they had been allowed to develop without overfishing,' he said.

The report was released as BP announced 'encouraging' progress on its 'static kill' attempt to seal the leak.

The U.S. official in charge of the spill also announced BP would start pumping cement into its blown-out oil well to begin sealing the leak for good.

'Based on the successful completion of the static kill procedure and a positive evaluation of the test results, I have authorized BP to cement its damaged well,' retired Coast Guard Admiral Thad Allen said in a brief statement.

According to the report unveiled yesterday by the U.S. National Oceanic and Atmospheric Administration, the remaining oil - mostly a light sheen on the surface or dispersed underwater - is breaking down rapidly.

The findings raise serious questions over the American government's torrid attacks on BP in the aftermath of the April 20 rig explosion that killed 11 workers and spilled millions of gallons of crude into the ocean.

Mr Obama has already been accused of targeting the British oil giant to avert fears the spill was becoming a political liability for his Democrat Party in the run-up to the November mid-term elections.

But last night the White House ruled out an apology for beleaguered outgoing BP chief executive Tony Hayward.

Fishermen and businesses in the devastated Gulf region that have lost millions of pounds worth of business because of the oil scare will be asking whether the effects of the leak have been hugely exaggerated.

White House energy adviser Carol Browner had to acknowledge the success of the clean-up operation yesterday as the scientists' report playing down the scale of the disaster was unveiled.

She said: 'The vast majority of the oil has been contained, it's been burned, it's been cleaned. The scientists are telling us about 25 per cent that was not captured or evaporated or taken care of by Mother Nature.'

She added that the remaining oil 'will break down naturally'.

But Ian MacDonald, a professor of oceanography at Florida State University, warned that even 25 per cent of the oil from the BP spill was five times the amount of oil lost in the 1989 Exxon Valdez disaster.

He said: 'An enormous amount of oil is now buried and we know from previous spills that this buried material can persist for decades.'

Pressure on the Obama administration to explain its approach to the disaster was growing in Washington as BP announced that its 'static kill' attempt to shut down the leak for good had worked.

BP said the success was a ' significant milestone' towards plugging the well permanently.

White House press secretary Robert Gibbs said no one owed Mr Hayward an apology.

He said the clean-up results would have been different if the U.S. had not pushed BP 'at every step of the way' to do things faster and more comprehensively.

Yesterday it was reported that BP faced $ 20billion of penalties because of the leak but it is unclear if this figure will stand.
