The Kuwaiti oil was 5-6 inches thick, the Mexican Ixtoc was a major spill and nothing remains.

Nothing remains?? Well maybe, but Ixtoc certainly caused a lot of damage, which the Mexican govt. did not pay for;

In the next nine months, experts and divers (including Red Adair[5]) were brought in to contain and cap the oil well. Approximately an average of ten thousand to thirty thousand barrels per day were discharged into the Gulf until it was finally capped on 23 March 1980.[6] Prevailing currents carried the oil towards the Texas coastline. The US government had two months to prepare booms to protect major inlets. Eventually, in the US, 162 miles (261 km) of beaches and 1421 birds were affected by 3,000,000 barrels (480,000 m3) of oil.[6] Mexico rejected US requests to be compensated for cleanup costs.

The oil slick surrounded Rancho Nuevo, in the Mexican state of Tamaulipas, which is one of the few nesting sites for Kemp's Ridley sea turtles. Thousands of baby sea turtles were airlifted to a clean portion of the Gulf of Mexico to help save the rare species.

Cat I am not arguing this is not a very bad event,I am trying to stay positive that it will end well.`

If BP can stop those other three leaks that will be a major step forward. If not, well...

someone earlier mentioned the blow out protector on this rig
it was most likely seriously damaged in the explosion and subsequent fires on the rig in this case rovs or acoustic or any other kind of devise would not work
we keep forgetting that most of these devices are all failsafe mechanisms
and on rigs believe me there are thousands of back up systems
the word redundant becomes redundant
they are breaking new ground on this one folks
never been done or tried
i wish them all godspeed

redundant is fine as long as you keep the redundant thing working and don't make decisions based on making money instead of following established protocol. (check the 60 Minutes interview that was on earlier tonight) Part of the problem is the redundant control panel on the bop was not functioning due to a dead battery, plus there was some human error. (no surprise)

as I stated earlier, hopefully this disaster will re-focus some energy on the whole oversight process regarding offshore drilling.

there will be plenty of time to assign blame. for now, I just hope we can stop this thing. no one knows the full extent of what we are facing.

Unhappy Scientists think oil has entered the loop current to the Keys

Oil Spill Florida Keys: Scientists Think Oil Has Entered Loop Current And Poses Grave Threat To Reefs

JASON DEAREN and MATT SEDENSKY | 05/17/10 12:31 PM | AP

NEW ORLEANS Delicate coral reefs already have been tainted by plumes of crude oil spewing into the Gulf of Mexico, including a sensitive area that federal officials had tried to protect from drilling and other dangers.

And marine scientists are worried even more of the deep-sea reefs could be damaged as the thick goo creeps into two powerful Gulf currents. The oil has seeped into areas that are essential to underwater life, and the reefs tend to be an indicator for sea health: when creatures in the reefs thrive, so do other marine life.

The loop current could carry oil from the spill east and spread it about 450 miles to the Florida Keys, while the Louisiana coastal current could move the oil as far west as central Texas.

The depth of the gushing leaks and the use of more than 580,000 gallons of chemicals to disperse the oil, including unprecedented injections deep in the sea, have helped keep the crude beneath the sea surface. Officials report that more than 390,000 gallons of chemicals are stockpiled. Marine scientists say diffusing and sinking the oil helps protect the surface species and the Gulf Coast shoreline but increases the chance of harming deep-sea reefs.

"At first we had a lot of concern about surface animals like turtles, whales and dolphins," said Paul Montagna, a marine biologist at Texas A&M University Corpus Christi who studies Gulf reefs. "Now we're concerned about everything."

On Sunday, researchers said computer models show oil has already entered the loop current that could carry the toxic goo toward the Keys, the third-longest barrier reef in the world.

The oil is now over the western edge of a roughly 61-mile expanse of 300-to-500-foot-deep reef south of Louisiana known as the Pinnacles, about 25 miles north of where the Deepwater Horizon exploded April 20, killing 11 people and starting the spill that grows by the hour.

The Pinnacles is one of nine coral banks and hard-bottom areas stretching from Texas to Florida that the National Oceanic and Atmospheric Administration tried in 2008 to get designated a marine sanctuary called Islands in the Stream.

This sanctuary would have restricted fishing and oil drilling around the identified reef "islands." But the plan was put on hold after vehement objections from Republican lawmakers, fishermen and the oil industry.
Story continues below

Scientists have found undersea plumes of oil at the spill as much as 10 miles long, which are an unprecedented danger to the deep sea environment, said Samantha Joye, a professor of marine sciences at the University of Georgia.

These plumes are being eaten by microbes thousands of feet deep, which removes oxygen from the water.

"Deepwater coral are abundant on the sea floor in this part of the Gulf, and they need oxygen," said Joye, who was involved in the plume discovery. "Without it, they can't survive."

Experts say the well's depth and Friday's decision by the U.S. Environmental Protection Agency to allow BP to shoot massive amounts of dispersing chemicals deep underwater may help protect vital marshes and wetlands on the Gulf Coast. But the tradeoff may result in significant effects on more sea life.

Oil mixed with the chemical agent can disperse into the water more easily, rather than it staying on the surface, where it could bypass deeper banks like Pinnacles, said Edward Van Vleet, a chemical oceanography professor at the University of South Florida.

The downside is that it causes oil to sink, coating corals and other reef organisms and smothering them, he said.

When the dispersed oil is broken into smaller globules, he said they are more easily eaten by smaller reef organisms and can kill them or cause tumors or something else harmful.

Federal officials who oversee marine sanctuaries and fisheries say it's too early to tell how reefs and other important habitats may be damaged, said Dr. Jane Lubchenco, NOAA's undersecretary of commerce for oceans.

NOAA, which manages marine sanctuaries, is also responsible for estimating financial costs of the spill on the sea environment and fisheries. The Pinnacles is a significant habitat for sea life vital to commercial fisheries such as red snapper, crab and shrimp.

The creation of a sanctuary across hundreds of miles of the Gulf would not have blocked oil and gas exploration where the Deepwater Horizon exploded, said Montagna. However, he said it could have resulted in stricter environmental regulation for reefs closest to the spill site, and likely less drilling.

"So you can imagine these animals that make a living on rocks, filtering food out of the water, and the dispersants come along and sink the oil; it's a big concern," Montagna said.

The area also is breeding ground for sperm whales and bluefin tuna, species not doing well, he said.

Studies published in a 2005 National Academy of Sciences report show that oil mixed with dispersants damaged certain corals' reproduction and deformed their larvae. The study concluded the federal government needed to study more before using massive amounts of dispersants.

Reefs are made up of living creatures that excrete a hard calcium carbonate exoskeleton.

Depending on the oil exposure, they can be smothered by the pollutants or become more susceptible to bleaching, which hinders reproduction and growth. While the warm temperatures of Florida could speed the recovery of damaged reefs there, some problems could be seen for a decade or more. In the deeper reefs in colder water closer to the spill, the damage could last even longer.

As the spill increases, the oil oozes toward other reefs that stretch from the blowout site eastward to the Florida Keys National Marine Sanctuary.

The Keys exist in relatively shallow water, so the potential exposure to the oil is higher than for deeper reefs, though BP PLC officials say the oil would be more diffused after having broken down during its travel over hundreds of miles.

This week, researchers from USF and the Florida Department of Environmental Protection are heading to the loop current to get a "chemical fingerprint" of any oil they find to confirm it is from the leaking well.

"We don't expect the loop current to carry oil onto beaches," William Hogarth, dean of the University of South Florida's College of Marine Science, said. "But we do have a great concern for the Keys."

If oil reaches the Keys, it could threaten one of the country's greatest underwater natural resources as well as its tourism industry.

Locals throughout the ribbon of islands not only relish their ties to the water but rely on it to help bring in 2 million visitors each year.

"They're not going to come if our beaches are tarred and our mangroves have died and it's a polluted dump," said Millard McCleary, program director of the Key West-based Reef Relief. "They'll go to the Bahamas or the Caymans or they'll go to Mexico."
