Scientists map and confirm origin of large, underwater hydrocarbon plume in Gulf

Scientists map and confirm origin of large, underwater hydrocarbon plume in Gulf

ScienceDaily (Aug. 19, 2010) — Scientists at the Woods Hole Oceanographic Institution (WHOI) have detected a plume of hydrocarbons that is at least 22 miles long and more than 3,000 feet below the surface of the Gulf of Mexico, a residue of the BP Deepwater Horizon oil spill.

In the study, which appears in the Aug. 19 issue of the journal Science, the researchers measured distinguishing petroleum hydrocarbons in the plume and, using them as an investigative tool, determined that the source of the plume could not have been natural oil seeps but had to have come from the blown out well.

Moreover, they reported that deep-sea microbes were degrading the plume relatively slowly, and that it was possible that the 1.2-mile-wide, 650-foot-high plume had and will persist for some time.
