BP officials said Sunday that a new mile-long tube is diverting some oil from the Deepwater Horizon well at the bottom of the Gulf of Mexico. It's the first time in more than three weeks that any of the company's strategies have worked to slow the flow.
Yet even as the company reported the success after weeks of fruitless efforts, scientists warned oil that has already spewed into the Gulf could have dire consequences for the environment. Computer models show the black ooze may have already entered a major current flowing toward the Florida Keys, a researcher told the Associated Press on Sunday.

Kent Wells, BP's senior vice president for exploration and production, said during a news conference that the amount being drawn was gradually increasing, and it would take several days to measure it.
The tube's success gave crews partial control of the leak for the first time since the rig Deepwater Horizon exploded April 20, killing 11 people. Still, Wells offered a tempered response to the news.
"It's a positive move, but let's keep it in context," he said Sunday.
Crews will slowly ramp up how much oil the tube collects over the next couple of days. They need to move slowly because they don't want too much frigid seawater entering the pipe, which could combine with gases to form ice-like crystals that would clog it.
The first chance to choke off the flow for good should come in about a week, when engineers plan to shoot heavy mud into the crippled blowout preventer on top of the well, then permanently entomb the leak in concrete. If that doesn't work, crews also can shoot golf balls and knotted rope into the nooks and crannies of the device to plug it, Wells said.
The final choice to end the leak is a relief well, but it is more than two months from completion.
Meanwhile, scientists warned of the effects of oil that has already leaked into the Gulf.
Computer models show the black ooze may have already entered the loop current — which is the largest in the Gulf — said William Hogarth, dean of the University of South Florida's College of Marine Science. A research vessel is being sent to the Gulf on Tuesday to collect samples and learn more.
One computer model shows that the oil has already entered the current, while a second model shows the oil is 3 miles from it — still dangerously close, Hogarth said. The models are based on weather, ocean current and spill data from the U.S. Navy and the National Oceanic and Atmospheric Administration, among other sources.
The current flows in a looping pattern in the Gulf, through the area where the blown-out well is, east to the Florida Keys National Marine Sanctuary and beyond.
Other scientists warned that miles-long underwater plumes of oil discovered in recent days could poison and suffocate sea life across the food chain, with damage that could endure for a decade or more.
Three or four large plumes have been found, at least one that is 10 miles long and a mile wide, said Samantha Joye, a marine science professor at the University of Georgia.
The hazardous effects of the plume are twofold. Joye said the oil itself can prove toxic to fish swimming in the sea, while vast amount of oxygen are also being sucked from the water by microbes that eat oil. Dispersants used to fight the oil are also food for the microbes, speeding up the oxygen depletion.
"So, first you have oily water that may be toxic to certain organisms and also the oxygen issue, so there are two problems here," said Joye, who's working with a group of scientists who discovered the underwater plumes in a recent boat expedition to the Gulf. "This can interrupt the food chain at the lowest level, and will trickle up and certainly impact organisms higher. Whales, dolphins and tuna all depend on lower depths to survive."
