Huge pool of hydrocarbons lurks in Gulf of Mexico

Huge pool of hydrocarbons lurks in Gulf of Mexico 20 Aug 2010 A plume of hydrocarbons from BP's oil spill is lurking deep in the Gulf of Mexico. The oily plume was over 35 kilometres long, up to 200 metres thick and up to two kilometres wide, and a kilo-metre below the surface, at the end of June, says a U.S. team from the Woods Hole Oceanographic Institution, which sent a submersible vehicle down for a close look. The scientists report that the submerged hydrocarbons were not being quickly biodegraded by microbes.
