Has BP Ruined the Entire Atlantic Basin?

This video paints a dismaying picture:



Via Mother Jones, which says:
The National Center for Atmospheric Research (NCAR) just released this horrifying animation of how ocean currents may carry all the oil in the Gulf of Mexico. According to their computer modeling of currents and the oil, the spill "might soon extend along thousands of miles of the Atlantic coast and open ocean as early as this summer."

"I've had a lot of people ask me, 'Will the oil reach Florida?'" says NCAR scientist Synte Peacock in a statement accompanying the animation, which he worked on. "Actually, our best knowledge says the scope of this environmental disaster is likely to reach far beyond Florida, with impacts that have yet to be understood."

The models show oil hitting Florida's Atlantic coast within a few weeks, then moving north as far as about Cape Hatteras, N.C., before heading east.
One question I haven't seen answered is: at what level of dispersion is the oil no longer harmful? I assume that if a hundred million gallons were distributed evenly throughout the world's oceans, it wouldn't even be noticeable, and would biodegrade in no time. But somewhere between that, and the actual conditions we have - giant plumes and enormous sheens concentrated in the northern Gulf of Mexico - is the threshhold beyond which dispersion takes care of the problem. I don't know what that threshhold is - whether, for instance, the quantities shown swirling about in the mid-Atlantic in this animation would still be dangerous to ecosystems. At the least, though, this looks bad for pretty much the entire coast of Florida.

Whither the Spill?

Thither, according to an oceanologist from the University of South Florida College of Marine Science Ocean Circulation Group, which has modeled the forecasted trajectory of the spill:



The narrator is expecting the slick to get caught up in the loop current, which feeds into the Gulf Stream, which runs up the East Coast of the US. Says he:
It's not looking good for the whole Gulf and for the East Coast, really... All these arrows are pushing it toward the loop current and once that happens, well, all bets are off... I hope that the people on the east coast are getting prepared for this, and Florida 'cause it looks like it's gonna come your way. It looks like it's not just a Gulf Coast deal.
At the end he gives two pieces of advice: to say our prayers, and to keep the pressure on BP to "spend every dime they have" on the clean-up. I humbly encourage my readers to put more energy into the latter.

Spill, Baby, Spill

Proving that you don't have to have centralized government control of your economy to wreak environmental havoc, that oil rig that blew up last week off the coast of Louisiana is causing problems:



So says Eric Berger:
Officials from Louisiana to Florida remain concerned about oil leaking from a Transocean rig that exploded last week in the Gulf of Mexico, killing 11.

As crews attempt to stop the flow of an estimated 42,000 gallons a day escaping from a pipe about 5,000 feet below the surface, the oil slick has been slowly expanding across the Gulf.

Satellite images have helped officials track the slick as it swirls around the Gulf. Here's the best, most recent image captured by NASA's Aqua satellite.
That's a thousand barrels of oil a day, leaking up from the bottom of the Gulf where the rig's pipe snapped off (those are technical terms). And it looks increasingly likely that the only thing that will work to stem the leakage is to drill a relief well, but that'll take months. (Part of the problem is that the well is 5,000 feet down, which complicates any potential engineering solution, as you can imagine - but those are the sorts of problems you run into when you're scrounging under the earth's proverbial sofa for the every last drop of fossil fuel resources you can find.) The slick is already 80 miles by 36 miles across and likely to reach land within days. This thing could get very ugly for the Gulf Coast.

UPDATE
: Now it's 100 x 45 miles.
