NEW ORLEANS – A thick, 22-mile plume of oil discovered by researchers off the BP spill site was nearing an underwater canyon, where it could poison the food Chain for sea life in the waters off Florida.
The discovery by researchers on the University of South Florida College of Marine Science's Weatherbird II vessel is the second significant undersea plume reported since the Deepwater Horizon exploded on April 20. The plume is more than 6 miles wide and its presence was reported Thursday.
The discovery was important, he said, because it confirmed that the substance found in the water was not naturally occurring and that the plume was at its highest concentration in deeper waters. The researchers will use further testing to determine whether the hydrocarbons they found are the result of dispersants or the emulsification of oil as it traveled away from the well.
The first such plume detected by scientists stretched from the well southwest toward the open sea, but this new undersea oil cloud is headed miles inland into shallower waters where many fish and other species reproduce.

The discovery by researchers on the University of South Florida College of Marine Science's Weatherbird II vessel is the second significant undersea plume reported since the Deepwater Horizon exploded on April 20. The plume is more than 6 miles wide and its presence was reported Thursday.
The cloud was nearing a large underwater canyon whose currents fuel the foodchain in Gulf waters off Florida and could potentially wash the tiny plants and animals that feed larger organisms in a stew of toxic chemicals, another researcher said Friday.- Larry McKinney, executive director of the Harte Research Institute for Gulf of Mexico Studies at Texas A&M University-Corpus Christi, said the DeSoto Canyon off the Florida Panhandle sends nutrient-rich water from the deep sea up to shallower waters.
McKinney said that in a best-case scenario, oil riding the current out of the canyon would rise close enough to the surface to be broken down by sunlight. But if the plume remains relatively intact, it could sweep down the west coast of Florida as a toxic soup as far as the Keys, through what he called some of the most productive parts of the Gulf.- The plume was detected just beneath the surface down to about 3,300 feet, said David Hollander, associate professor of chemical oceanography at USF.
- Hollander said the team detected the thickest amount of hydrocarbons, likely from the oil spewing from the blown out well, at about 1,300 feet in the same spot on two separate days this week.
