After big 1979 spill, a stunning recovery
... For Tunnell and others involved in the fight to contain the June 3, 1979, spill from Mexico's Ixtoc 1 offshore well in the Gulf of Campeche, the BP blowout in the Gulf of Mexico conjures an eerie sense of déjà vu.

Like the BP spill, the Ixtoc disaster began with a burst of gas followed by an explosion and fire, followed by a relentless gush of oil that resisted all attempts to block it. Plugs of mud and debris, chemical dispersants, booms skimming the surface of the water: Mexico's Pemex oil company tried them all, but still the spill inexorably crept ashore, first in southeast Mexico, later in Texas.

But if the BP spill seems to be repeating one truth already demonstrated in the Ixtoc spill - that human technology is no match for a high-pressure undersea oil blowout - scientists are hoping that it may eventually confirm another: that the environment has a stunning capacity to heal itself from manmade insults.

"The environment is amazingly resilient, more so than most people understand," says Luis A. Soto, a deep-sea biologist with advanced degrees from Florida State University and the University of Miami who teaches at the National Autonomous University of Mexico.

"To be honest, considering the magnitude of the spill, we thought the Ixtoc spill was going to have catastrophic effects for decades. ... But within a couple of years, almost everything was close to 100 percent normal again."...
