There is definitely a deep plume of oil in the Gulf of Mexico, and it was definitely produced by BP’s damaged Macondo well, according to a report published today in Science. Scientists from the Woods Hole Oceanographic Institution (WHOI) in Massachusetts reported unequivocal evidence of a plume at a depth of about 1,100 meters that was at least 35 kilometers long, as of the end of June. The plume, they said, was traveling to the southwest, largely driven by the topography of the seafloor.

BP’s new cap system, installed to stop the oil spilling into the Gulf, is now working, BP announced this week, though how long it will hold remains to be seen.

Brown pelicans mired in oily mud along the Louisiana coast are icons of the BP Deepwater Horizon oil spill, daily reminders of the ongoing disaster’s impact on the Gulf coast. Yet, says a leading marine ecologist, the greater long-term danger to wildlife may be occurring out of sight, deep beneath the oily surface of the water.

It’s been about eight weeks since an explosion on the Deepwater Horizon drilling rig damaged a wellhead in the Gulf of Mexico and triggered the onset of the largest offshore oil spill in U.S. history, with oil washing up on shores from Louisiana to northwestern Florida.

In the Gulf of Mexico lurk menacing masses of single-celled organisms known as red tides. Scientists have long known that the potent toxin they produce can kill fish and birds, wreak havoc on the human nervous system and cause wheezing, sneezing and asthma flare-ups. But new research suggests that it can also damage DNA, which could lead to more subtle, longer-term health consequences.
