A mile under sea, the US oil leak continues to flow

BP has released new footage of oil gushing from the broken pipe that rests nearly a mile under water, contaminating the Gulf of Mexico.
The images show oil pouring from a break in the yellow pipe, and becoming lighter in colour as it mixes with natural gas.
Over the past 21 days, more than four million gallons of oil have been released since the Deepwater Horizon exploded in the Gulf of Mexico.
Speaking at a news conference on Wednesday, BP chief operating officer Doug Suttles said that the flow rate looked "pretty much the same as it has always looked".
Meanwhile, a new containment box, a cylinder called a "top hat", was placed on the sea floor near the well leak.

UNDERWATER EFFORTS TO CAP OIL LEAK


Initially, BP tried to lower a 125-tonne, 18-metre (59 feet) high container dome over the main leak on the sea floor. However, this failed when gas leaking from the pipe mixed with water to form hydrates, ice-like crystals, that blocked up the steel canopy.
