Well, scientists have discovered one possible reason why the Gulf Coast oil spill is taking so long to contain and clean up: large plumes of oil are lurking under the surface.

It has been nearly a month since the Deepwater Horizon rig exploded and still the containment is an issue. Since the oil spill began, roughly 210,000 gallons of oil have flowed into the Gulf of Mexico and has either slowly drifted towards the coast or further out to sea. A number of birds have already been affected by the spill and there is also the possibility that some turtles and dolphins have fell victim to this mess, as well.

BP, the company that was leasing the oil rig at the time, is currently at the head of containment and cleanup operations and so far, none of their plans have worked. Their most recent attempt involves using a mile-long pipe to trap the oil flowing into the Gulf; however, engineers failed to connect 2 pieces of equipment yet.
