Lack of Gulf Oil Disaster Is No Surprise to Polifrog -- The Gulf, A Perfect Place to Drill...

They could have just asked Polifrog.

The government is expected to announce on Wednesday that three-quarters of the oil from the Deepwater Horizon leak has already evaporated, dispersed, been captured or otherwise eliminated — and that much of the rest is so diluted that it does not seem to pose much additional risk of harm.

Reposted below is Polifrog's May 3rd piece on the BP oil spill:

First off, this is a developing story.
But, secondly, where is, at least, some of the predicted devastation?

Nearly two weeks ago one of BP's oil drilling platform suffered an accident. BP’s estimate is that the well produces some 5,000 barrels of crude oil per day and currently covers around 7500 sq/miles.

Images of the Valdez spill in 89 (250,000 barrels spilled over 11,000 sq/miles) immediately spring to mind. But is it accurate to compare the current spill to Valdez?

I don't think so. There is too much that is different.

For instance,

Viscosity. The oil being spilled in the Gulf is less viscous than the oil spilled by the Valdez. Not only is it less viscous due to its nature, but also due to the higher temperatures in the gulf. This is why we will not likely see the same type of sludge we saw associated with Valdez.

Latitude and resulting albeto. The interaction between sunlight and water changes based on latitude. In lower latitudes the sun hits the surface of the water at a very steep angle which means that the light penetrates the water more than it does at higher latitudes.

These two above combine to thin the oil and help aid its evaporation to a greater degree in the gulf than in Prince William Sound Bay.

Environment. The Gulf is known to naturally leak oil due to natural underground seepage. The natural leakage is of similar volume to the BP tragedy currently unfolding. Of course, doubling the amount of oil leaking into the Gulf and dumping it all in one place is not a good thing, but it is also obvious that the Gulf is capable of absorbing oil to a large degree. Oil is incorporated in the Gulf's ecosystem whereas it is a foreign substance in Price William Sound.

What if it turns out that the Gulf is a uniquely resilient ecosystem to oil spills?

We can only hope that this will be a disaster that never was.

The Gulf is the perfect place to drill for oil.
