This is not the first oil spill in the Gulf of Mexico from an oil rig. This happened once before in 1979 and leaked for 9 months before it was finally plugged.
1979 OIL SPILL
Gulf oil spill has 'perfect precedence' in 1979 disaster.

The exploratory oil well two miles below the surface of the Gulf of Mexico exploded in a ball of fire, spurting millions of gallons of crude into the sea. As weeks turned to months, oil executives grappled with capping the well. The growing slick turned into an immediate ecological nightmare.
The year was 1979. The blowout of the Ixtoc I, drilled by the Mexican-run Pemex, retains the dubious record of causing the world's largest accidental oil spill, dumping an estimated 138 million gallons over nine months. Eventually, Pemex cut off Ixtoc I with two relief wells and a cement seal.
With top BP executives, scientists and Obama administration officials searching for a solution to capping the Deepwater Horizon blowout off the Louisiana coast, perhaps they could find a blueprint in the Ixtoc I experience, observers say. They also may find lessons from the Montara oil spill last August off the northern coast of Australia, where it took five tries and nearly three months to stop the flow of as many as 84,000 gallons a day into the Timor Sea.
If some scientists, who say BP and the U.S. Coast Guard are underestimating how much oil is leaking now, are right, the current gusher could easily eclipse the demise of Ixtoc I in the Bay of Campeche. By their count, instead of the 210,000 gallons leaking per day, it's more like 4 million.
``Everybody keeps saying the spill in the Gulf is unprecedented,'' said geologist John Amos, president and founder of SkyTruth, a nonprofit that investigates environmental issues using satellite images. ``That is such nonsense (nonsense subsitituted for a word that is not allowed per forum rules). We had perfect precedence.''
THE IXTOC I
When the Ixtoc I burst into flames on June, 3, 1979, Wes Tunnell and other researchers had to figure out how long it would take the current to carry the oil, in one form or another, 600 miles to south Texas.
``We projected that it would reach the Texas coast in about two months. It exactly did,'' he said. By August, ``it coated the Texas beaches in a ribbon of oil 30 to 50 feet in width from Rio Grande to Port Aransas.''
In some places, the coating of oily sludge was only an inch deep. In others, it was a nearly a foot-and-a-half layer, he said, turning off tourists.
``The south Texas restaurant and hotel organizations, at the time, claimed that they lost $50 million in revenue. Back then that was a lot.''
The lead time did help, however, said Tunnell, 65, who doesn't do as much field work now, as associate director of the Harte Research Institute for Gulf of Mexico Studies. While the edges of the region's barrier islands turned black, booms laid across the few entrances to the area's lagoons kept much of the oil out of some of the most fragile ecosystems, he said.
That's far different than the intricate, exposed marshes of Louisiana now in peril from Deepwater Horizon oil.
Measuring the recovery of the south Texas coast was difficult, he said. A tropical storm hit the oily beaches in September, as Pemex struggled to cap Ixtoc.
``The tropical storms helped clean off the Texas beaches,'' he said, and some environmental studies were abandoned as a result. ``The good side is, between one and three years later, everything was back to normal. It doesn't take long for these sandy beach habitats to replenish themselves.''
Tom Linten, now a senior lecturer at Texas A&M University -- Galveston, was hired to spread oil dispersant over the Gulf in 1979. He commissioned a Canadian plane used to put out forest fires to spread the chemical over the open sea.
``When that plane came over and hit [the oil], it was like a curtain was pulled back or something. It disappeared,'' said Linten, 74. ``We were all standing there thinking, `My God. That was unbelievable.' ''
As Linten, 74, watches developments surrounding the latest spill in the Gulf, he leaves predictions about what will happen to the legion of scientists and specialists gathered in Louisiana. ``Compared to what they have these days, we were like horse and buggy. I have confidence with the great advances in technology, robots, et cetera, et cetera, this thing will be brought under control.''
MONTARA OIL SPILL
Those wishing the oil industry had learned its lesson -- and that technology had truly advanced over the last 30 years -- say a catastrophic spill less than a year ago in the Timor Sea dispels any notions about the industry's evolution.
In the waters between Australia and Indonesia, a Thai-company's well blew out in a similar fashion to what occured in the Gulf of Mexico last month. ``It's an eerie foreshadowing of this,'' said Amos, of SkyTruth. ``There was a willful disregard of that spill.''
The tally of oil that spewed into the ocean from the so-called Montara spill varies from 1.2 million gallons to 9 million gallons. It took 10 weeks and five attempts at drilling relief wells to stop the leak.
As the concerns about oil contaminating the Gulf coast's fragile marshes become reality, environmental fallout on the other side of the world is already being realized from last year's spill.
``Literally dozens of species including birds, dolphins, turtles, sea snakes, fish and whales move through the area affected by the Timor Sea spill. Thousands of individual animals will feel the full force of a toxic cocktail of sweet light crude and dispersant chemicals,'' said Gilly Llewellyn, the World Wildlife Fund's conservation manager in Australia.
``During our research expedition to the area, I witnessed pods of dolphins swimming through oiled water, a heartbreaking sight. And what we managed to see on the surface was undoubtedly just a fraction of what was happening.''
``This no-holds-barred pursuit of oil and gas is madness,'' she said, adding that the Australian government recently approved new drilling areas off its coasts.
``Governments around the globe must learn a lesson from these catastrophes and think long and hard about drilling in sensitive areas. What if a spill the size of the one in the Gulf were to happen in the Great Barrier Reef, or the Arctic?''
