Oil Spill to Reach Atlantic Ocean
May 17, 2010
The oil spill from a British Petroleum (BP) sunken rig in the Gulf of Mexico may have reached a major current in the Atlantic Ocean, scientists say.
Computer models show the oil may have already entered a water stream, known as the ‘loop current,’ which could propel plumes of oil into the Atlantic Ocean, William Hogarth, a researcher at the University of South Florida’s College of Marine Science said on Sunday, the Associated Press reported.
Other scientists, however, say that damage is already done and it is not clear how much more oil is to come.
“Obviously the quicker they plug this, the better, but they are already having a tremendous effect on the environment,” said Paul Montagna, from the Harte Research Institute for Gulf of Mexico Studies in Texas.
Meanwhile, after many setbacks, BP managed to plug a tube into the ruptured wellhead on Sunday and partially funnel the crude into a tanker ship.
However, millions of liters of oil already in the Gulf of Mexico have endangered the ecosystem and environment.
The crisis started three weeks ago when the Deepwater Horizon rig exploded and the wellhead, beneath it, ruptured. As a result of the incident, an estimated 5,000 barrels of oil is gushed into water everyday.
The leak, which is said to be spreading ten times faster than had been estimated, has already eclipsed the 1989 Exxon Valdez spill, as the worst environmental disaster in the United States.
Gulf Oil Is in the Loop Current, Experts Say

Satellite pictures show the Gulf oil spill moving toward the Loop Current, which is illustrated at bottom.
Some oil from the Gulf of Mexico spill is “increasingly likely” to be dragged into a strong current that hugs Florida’s coasts, National Oceanic and Atmospheric Administration (NOAA) officials said today.
But other experts say that the oil is already there—satellite images show oil caught up in one of the eddies, or powerful whorls, attached to the Loop Current, a high-speed stream that pulses north into the Gulf of Mexico and travels in a clockwise pattern toward Florida.
Images from the past few days show a “big, wide tongue” of oil reaching south from the main area of the spill, off the coast of Louisiana, said Nan Walker, director of Louisiana State University’s Earth Scan Laboratory, in the School of the Coast and Environment.
Meanwhile, a particular eddy has intensified and expanded north in recent days. The images reveal that the eddy has snagged oil and pulled it southeastward 100 miles (about 160 kilometers), which means the crude is now circulating inside the turbulent waters.
The oil has also reached the point where the eddy connects to the Loop Current, Walker said. That means the oil is traveling eastward alongside the main stream of the Loop Current, and it’s likely that it will continue flowing with the current to Florida, Walker said.
Mitchell Roffer, president of Roffer’s Ocean Fishing Forecasting Service in West Melbourne, Florida, has also been tracking the oil spill by satellite.
“Several scientists from different organizations have seen the oil in the Loop Current” via “clear and dramatic” satellite pictures, Roffer said.
