Scientists discover huge new oil plume in Gulf

Marine scientists have discovered a massive new plume of what they believe to be oil deep beneath the Gulf of Mexico, stretching 22 miles (35km) from the leaking wellhead north-east towards Mobile Bay, Alabama.

The discovery by researchers on the University of South Florida College of Marine Science’s Weatherbird II vessel is the second significant undersea plume recorded since the Deepwater Horizon exploded on April 20.
