oxide7 writes "An underwater three-dimensional map of the oil spill is closer to becoming a reality, now that the US has for the first time confirmed the discovery of a subsurface oil plume resulting from the ruptured BP well. The government agency in charge of ocean science has received the first of several expected reports from university investigators aboard research ships detailing specific locations where oil has been found below the surface of the Gulf of Mexico. The government, which denied reports of giant underwater oil plumes in mid-May, said researchers at the time had not confirmed the presence of conglomerated oil."
The New York Times talked with scientists on a two-week mission in the Gulf and reported them "awed" at the size and density
of the underwater plume.
