Where’s the Oil?

Thursday, July 29th, 2010

The Oil on the surface in the Gulf has seemed to disappear. Where did it go? My bet is that it is still there, below the surface and the Marshes are still loaded with it. Let’s see what the “experts” say.

Oil in gulf is degrading, becoming harder to find, NOAA head says

Oil from the BP blowout is degrading rapidly in the warm waters of the Gulf of Mexico and becoming increasingly difficult to find on the water surface, the head of the National Oceanic and Atmospheric Administration said Tuesday.

“The light crude oil is biodegrading quickly,” NOAA director Jane Lubchenco said during the response team daily briefing. “We know that a significant amount of the oil has dispersed and been biodegraded by naturally occurring bacteria.”

Lubchenco said, however, that both the near- and long-term environmental effects of the release of several million barrels of oil remain serious and to some extent unpredictable.

“The sheer volume of oil that’s out there has to mean there are some pretty significant impacts,” she said. “What we have yet to determine is the full impact the oil will have not just on the shoreline, not just on wildlife, but beneath the surface.”

But much of the oil appears to have been broken down into tiny, microscopic particles that are being consumed by bacteria. Little or none of the oil is on seafloor, she said, but is instead floating in the gulf waters.

Her conclusions come from the work of several NOAA boats now collecting water samples, as well as the analysis of academics brought in to help study the spill effects. The goal, she said, is to get a scientifically sound assessment of the overall environmental effects of the spill.

“To do this, we’re working with the best scientific minds in the government, as well as the independent scientific community, to produce an estimate of just how much oil has been skimmed, burned, contained, evaporated and dispersed,” she said. “We’re getting close to an answer.”

And from the NY Times:

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.

From the Washington Post:

Now, 14 days after the well was closed and 100 days after the blowout, U.S. government scientists are working on calculations that could shed some light on Hayward’s analysis (even if they can’t shed light on why he said it). They are trying to figure out where all the oil went.

Up to 4 million barrels (167 million gallons), the vast majority of the spill, remains unaccounted for in government statistics. Some of it has, most likely, been cleaned up by nature. Other amounts may be gone from the water, but they could have taken on a second life as contaminants in the air, or in landfills around the Gulf Coast.

And some oil is still out there — probably mixed with chemical dispersants. Some scientists have described it floating in underwater clouds, which one compared to a toxic fog.

“That stuff’s somewhere,” said James H. Cowan Jr., a professor at Louisiana State University. His research has shown concentrations of oil still floating miles from the wellhead. “It’s going to be with us for a while. I’m worried about some habitats being exposed chronically to low concentrations of toxins. . . . If the water’s contaminated, the animals are going to be contaminated.”

‘The truth is in the middle’

We’ll be living with the mess for at least this century. And Just because you can’t see it, doesn’t mean it’s not there in some shape or toxic form.

Peanut Butter – Is Government Doing Enough in the Gulf?

Thursday, May 20th, 2010

It’s been almost a month and the under water gusher is still spewing oil. BP has tried many things to try to control or stop the gusher. Everything THEY know to do but are being very secretive about the amount of oil. In the meantime there have been no tests by our Government to monitor the environmental impact of this gusher to the land, the sea and the oceans. This is disturbing many scientists who now are blaming the Government.

From the NY Times:

Scientists Fault U.S. Response in Assessing Gulf Oil Spill
By JUSTIN GILLIS

Tensions between the Obama administration and the scientific community over the gulf oil spill are escalating, with prominent oceanographers accusing the government of failing to conduct an adequate scientific analysis of the damage and of allowing BP to obscure the spill’s true scope.

The scientists assert that the National Oceanic and Atmospheric Administration and other agencies have been slow to investigate the magnitude of the spill and the damage it is causing in the deep ocean. They are especially concerned about getting a better handle on problems that may be occurring from large plumes of oil droplets that appear to be spreading beneath the ocean surface.

The scientists point out that in the month since the Deepwater Horizon oil rig exploded, the government has failed to make public a single test result on water from the deep ocean. And the scientists say the administration has been too reluctant to demand an accurate analysis of how many gallons of oil are flowing into the sea from the gushing oil well.

“It seems baffling that we don’t know how much oil is being spilled,” Sylvia Earle, a famed oceanographer, said Wednesday on Capitol Hill. “It seems baffling that we don’t know where the oil is in the water column.”

The administration acknowledges that its scientific resources are stretched by the disaster, but contends that it is moving to get better information, including a more complete picture of the underwater plumes.

“We’re in the early stages of doing that, and we do not have a comprehensive understanding as of yet of where that oil is,” Jane Lubchenco, the NOAA administrator, told Congress on Wednesday. “But we are devoting all possible resources to understanding where the oil is and what its impact might be.”

The administration has mounted a huge response to the spill, deploying 1,105 vessels to try to skim oil, burn it and block it from shorelines. As part of the effort, the federal government and the Gulf Coast states have begun an extensive effort to catalog any environmental damage to the coast. The Environmental Protection Agency is releasing results from water sampling near shore. In most places, save for parts of Louisiana, the contamination appears modest so far.

The big scientific question now is what is happening in deeper water. While it is clear that water samples have been taken, the results have not been made public.

Lisa P. Jackson, administrator of the Environmental Protection Agency, told Congress on Wednesday that she was pressing for the release of additional test results, including some samples taken by boats under contract to BP.

While the total number of boats involved in the response is high, relatively few are involved in scientific assessment of the deep ocean.

Of the 19 research vessels owned by NOAA, 5 are in the Gulf of Mexico and available for work on the spill, Dr. Lubchenco said, counting a newly commissioned boat. The flagship of the NOAA fleet, the research vessel Ronald H. Brown, was off the coast of Africa when the spill occurred on April 20, and according to NOAA tracking logs, it was not redirected until about May 11, three weeks after the disaster began. It is sailing toward the gulf.

At least one vessel under contract to BP has collected samples from deep water, and so have a handful of university ships. NOAA is dropping instruments into the sea that should help give a better picture of conditions.

On May 6, NOAA called attention to its role in financing the work of a small research ship called the Pelican, owned by a university consortium in Louisiana. But when scientists aboard that vessel reported over the weekend that they had discovered large plumes undersea that appeared to be made of oil droplets, NOAA criticized the results as premature and requiring further analysis.

Rick Steiner, a marine biologist and a veteran of the 1989 Exxon Valdez disaster, assailed NOAA in an interview, declaring that it had been derelict in analyzing conditions beneath the sea.

Mr. Steiner said the likelihood of extensive undersea plumes of oil droplets should have been anticipated from the moment the spill began, given that such an effect from deepwater blowouts had been predicted in the scientific literature for more than a decade, and confirmed in a test off the coast of Norway. An extensive sampling program to map and characterize those plumes should have been put in place from the first days of the spill, he said.

“A vast ecosystem is being exposed to contaminants right now, and nobody’s watching it,” Mr. Steiner said. “That seems to me like a catastrophic failure on the part of NOAA.”

Mr. Steiner, long critical of offshore drilling, has fought past battles involving NOAA, including one in which he was stripped of a small university grant financed by the agency. He later resigned from the University of Alaska at Anchorage and now consults worldwide on oil-spill prevention and response. Read more at link.

BP’s secretiveness hasn’t helped. The Congress has demanded for them to release videos of the gusher and yesterday BP turned back a CBS news crew from filming the oil that came ashore. It’s time for the Government to take the lead and demand that BP work under the lead of a government agency. They should also allow other scientists and definitely allow the media to show what is happening, good and bad!

Oil spill’s economic damage could be permanent

BP has promised to cover all legitimate claims, but the law caps its liability, and relief might take years to reach those whose livelihoods are most in peril.

“At ground zero in these disasters, there are people who are simply annihilated,” said Mark Cooper, senior fellow at the Institute for Energy and Environment at the Vermont Law School. “If it doesn’t happen in the first few years, it won’t really help.”

Oil slick reaches Louisiana’s barrier islands

An orange sheen washes onto beaches as BP starts lowering a dome to try to contain oil gushing from the seafloor.

“We have now had reports of oil ashore,” Coast Guard Petty Officer David Mosley said. Overflights found the sheen that marks the advancing edge of the massive slick hovering off the Louisiana coast, as well as heavier oil on both sides of the Chandeleur Islands, about 60 miles east of New Orleans.

Cleanup crews were dispatched to the crescent-shaped string of islands, which are part of the Breton National Wildlife Refuge created in 1904 by President Theodore Roosevelt.

Jaqui Michel, an oil spill cleanup expert with the National Oceanic and Atmospheric Administration, said “light-orange mooshy-looking stuff” was working its way toward island marshes and rookeries for thousands of pelicans, the state bird.

Gulf oil spill: NOAA taking samples deeper in water column

The National Oceanic and Atmospheric Administration has redirected a mission that was to examine deep-sea corals to the Gulf of Mexico, where oil has been gushing into the sea at 200,000 gallons a day since April 22.

The research ship will collect seafloor and water column data and obtain core sediment samples from the seafloor in areas near the Deepwater Horizon spill source. The samples are expected to provide important information about the abundance of marine organisms and the presence of chemicals in ocean water and sediments for a baseline against which to measure change if those areas are affected by sinking oil.

NOAA already is taking samples of seafood and analyzing them to establish a baseline from which it could determine if future samples are contaminated by the oil.

NOAA writes:

That study site is about nine miles from the oil spill source and the home of the Gulf of Mexico Consortium’s Methane Hydrate Seafloor Observatory. In the seven years of the observatory’s development, scientists have collected a wealth of geologic, physical, chemical, and biological data describing the area — data that could be important in measuring changes there that stem from the oil spill.

The research team brought aboard a large box corer used to take seafloor sediment samples and installed a large reel of cable to allow the corer to operate at depths equal to the spill source at 5,000 feet. An instrument called a CTD (Conductivity-Temperature-Depth) will measure the water’s conductivity, temperature, density and oxygen concentration at various water column depths, while bottles on the CTD obtain water samples.

There was little MSM coverage of this yesterday. We have to keep this as a top  story or BP may get away with ducking some of their responsibility. Remember the Valdez!
