Oil spill in Gulf of Mexico

What does the oil spill in the Gulf of Mexico is really a serious threat? As Murphy’s Law states that "if there is a probability of some kind of trouble, it will happen." Major bummer, consisting of a chain of smaller coincidences occurred in the Gulf of Mexico.

If you summarize the main statements of experts, they will look as follows: the flow of oil from the well is not terminated, the type of crude that mixes easily with water, the result is a viscous mixture that is poorly lit, and peeled off even worse, with oil spills in sensitive spawning areas that critically important for the continuation of the life cycle of many marine creatures, swampy shoreline, which greatly complicates its purification from crude oil.

Among the experts are always there was talk about "the potential for a major disaster," said Tunnell Weight (Wes Tunnell) an expert in the field of coastal ecology and oil spill from the University of Texas.

"It’s really a major disaster. Happened the very catastrophe which for so long talk."

More than 800,000 gallons of oil gush daily from the exploding borehole oil company British Petroleum called Deepwater Horizon, which exploded April 20 and sank two days later. In the rescue effort involved more than 6 radio-controlled cars, with which the rescue team is trying to close an underwater valve, unfortunately so far without success. Meanwhile, the strong currents and winds carry splodge through barriers that are designed to restrain it. In addition to British Petroleum, trying to minimize the damage a lot of government agencies.

Experts on oil leaks, conduct exercises every few years to practice actions to respond to the leak of "national significance." The exercises were held last month in Maine. But the Gulf of Mexico is a "combination of various negative factors," which makes it a lot worse than they could have imagined the exercise, said Nancy Kinner (Nancy Kinner) from the University of New Hampshire.

Leak occurred - the "worst possible scenario", said Tunnell. The worst thing - the fact that the leak from the mine is still going on. Mine is only 64 km from the coastal zone, and the leak can go on for months before you can drill Silencing the well to stop the flow.

Ed Overton (Ed Overton) from Louisiana State University, leading the federal chemical hazard assessment team of the oil spill, said: "I do not believe that they will be able to drill a well in Silencing for three months."

"The type of oil is also a major problem. Though most of the oil produced in Louisiana light varieties, this case is no exception. This is a heavier blend because it lies deep beneath the surface of the ocean," - said Overton - "If I had to choose the worst oil, I would choose this oil. only thing that is comforting is the fact that it contains not a lot of sulfur, because sulfur has a very bad smell. "

According to him, the first analysis of samples of the spilled oil has shown its content of asphalt-like substances that create a rather sticky mud. The reason for this is the fact that the oil is older than most oil in the region and very dense.

Also, this oil emulsifies well, Overton said. Emulsification - a process of thorough mixing of water and oil, which creates a substance similar to a shampoo that contains mainly water, said professor Anil Kulkarni (Anil Kulkarni).

If such confusion occurred, such oil does not evaporate as easily as conventional oil, it is difficult flushing, recycling oil-eating microbes and burning, the expert said.

Such mixing is actually deprived us of the most effective types of cleaning weapons in one voice say experts.

If circumstances were different, with calmer winds and water, the oil could rise to the surface does not emulsify, but, unfortunately, in this case, the tide has turned against us, said Kulkarni. Until the moment when it reaches the surface, the mixing has occurred.

The wind and the waves carry oil directly into the most sensitive coastal areas - in the marshland of Louisiana and neighboring states.

There are three types of beaches: sandy, rocky and marshy. Sandy beaches, such as in Florida, the easiest to clean, Overton said. The biggest difficulty is the marshy beaches, and that’s where oil is sent.

Marshland is so delicate that just trying to clean it, we have harmed, said Kinnear. During the first after being hit by oil, remove all vegetation. But oil also penetrates the soil and it becomes extremely difficult to clean.

The bacteria that eats oil needs oxygen, which is not enough in the swamps.

Another negative factor - this time of year. After all this time of year in the Gulf of Mexico spawning fish and plankton blooms - the whole ecosystem is in a vulnerable position. All the details about the main events of the day widgets news let us know.
