tarfish-like critters that are normally bright orange but now are pale and dead


Gucci outlet "Everything may be fine in some places, but definitely not fine everywhere," said University of Georgia researcher Samantha Joye who found dead patches of oiled sea bottom in expeditions near the busted well where 11 men lost their lives. "The oil isn't gone; it's just not where we can see it." Joye said before the oil spill she would have given the sea floor an "A'' grade of 90. Now she gives it a 30. Overall, Joye, who has been one of the more hands-on researchers exploring Gulf damage, said its health has plunged from an 80 before the spill to a 50 now, but she was the most pessimistic of the researchers. In five different expeditions, the last one in December, she and her colleagues took 250 cores of the sea floor and travelled 2,600 square miles. She also has pictures of oil-choked bottom-dwelling creatures like crabs and brittle stars — starfish-like critters that are normally bright orange but now are pale and dead.

Burberry Outlet This is hidden from view. Eugene Turner, an LSU wetlands scientist, has looked at marshes in Louisiana's Barataria basin, and found oil buried in the mud and sand. "You can't smell it. You can't see it. It's not this big black scum out there, but it's there," Turner said. At this point, the oil is only obvious in a couple of places — with Bay Jimmy the worst-hit. Today, a crust of oil still lines miles of the outer fringe of marsh in the bay, a remote spot deep visited by the occasional fisherman and oil worker. Still, it's nothing compared to the black gunk stuck on beaches and marshes last summer or the multi-colored slicks so massive they could be tracked by satellite. Those images, along with the pictures of pelicans and seagulls with gobs of oil oozing down their beaks, are now history.

Five finger shoes "Even though some coastal areas were hit hard," says NOAA's Lubchenco, "the oil did not penetrate as far into the marshes as people feared." Despite the picture on the surface, Dana Wetzel at the Mote Marine Laboratory in Florida, adds: "Anyone who says the Gulf is fine is being precipitous.... It's out-of-sight, out-of-mind, but in my humble opinion this is not over." While BP money has flowed for immediate cleanup and compensation, the bigger bill for environmental damage and federal penalties is still being calculated. The federal government is collecting data on that, but much is kept from outside scientists. So some of the most important details are being held closely like cards in a high-stakes poker game, outside researchers say.

Louis Vuitton Outlet Trying to quantify the scale of the injury to the Gulf ecosystem "is absolutely the right question," said Robert Haddad, who heads the scientific process for the National Oceanic and Atmospheric Administration. "One of the outcomes from the Exxon Valdez was that they tried to estimate the damage too quickly." The spill itself lasted nearly three months. Then there was the clean-up. Then federal officials pronounced the oil mostly — but not completely — gone, eaten by microbes, dispersed by chemicals or diluted. Lubchenco told reporters in February that "it's not a contradiction to say that although most of the oil is gone, there still remains oil out there." Now, only a year later scientists are starting to see signs — and they are far from conclusive — of possible long-term problems.

Scientists: Gulf health nearly at pre-spill level


Gucci outlet BAY JIMMY, La. (AP) — Scientists judge the overall health of the Gulf of Mexico as nearly back to normal one year after the BP oil spill, but with glaring blemishes that restrain their optimism about nature's resiliency, an Associated Press survey of researchers shows. What's remarkable is that that's just a few points below the 71 the same researchers gave last summer when asked what grade they would give the ecosystem before the spill. And it's an improvement from the 65 given back in October. At the same time, scientists are worried. They cite significant declines in key health indicators such as the sea floor, dolphins and oysters. In interviews, dozens of Gulf experts emphasized their concerns, pointing to the mysterious deaths of hundreds of young dolphins and turtles, strangely stained crabs and dead patches on the sea floor.

Burberry Outlet EDITOR'S NOTE — it will take time to see the full effects of the oil spill on the Gulf of Mexico. Now, scientists grade the ecological health of the Gulf in an Associated Press survey one year after the April 20, 2010, BP oil spill. The survey results mirror impressions Jane Lubchenco, the head of the National Oceanic and Atmospheric Administration gave on the health of the Gulf in an interview with the AP Thursday. It's premature to conclude that things are good ... There are surprises coming up — we're finding dead baby dolphins." Just as it was before the April 20 accident when the Deepwater Horizon oil rig exploded, ultimately spewing 172 million gallons of oil, the Gulf continues to be a place of contradictions: The surface looks as if nothing ever happened while potentially big problems are hidden deep below the surface, in hard-to-get-to marshes and in the slow-moving food web. Some may not even be known for years.

five finger shoes "When considering the entire Gulf of Mexico, I think the natural restoration of the Gulf is back to close to where it was before the spill," said Wes Tunnell at Texas A&M University, who wrote a scientific advisory report for the federal arbitrator who is awarding money to residents and businesses because of the oil spill. Tunnell's grades are typical. He says the Gulf's overall health before the spill was a 70; he gives it a 69 now. If that pre-spill grade isn't impressive, it's because the Gulf has long been an environmental victim— oil from drilling and natural seepage, overfishing, hurricanes and a huge oxygen-depleted dead zone caused by absorbing 40 percent of America's farm and urban runoff from the Mississippi River. Today, a dozen scientists give the Gulf as good a grade as they did before the spill. One of those is Louisiana State University professor Ed Overton, a veteran of oil spills.

Louis Vuitton Outlet He described a recent trip to Gulf Shores, Ala.: "I walked a half-mile down the beach and there wasn't a tar ball in sight. It was as pretty as I've ever seen it." In the survey, some categories, such as red snapper and king mackerel, even average out to higher grades than before the spill, mostly because months of partial fishing bans have helped populations thrive.While that sounds good, the average grades for the sea floor plunged from 68 pre-spill to a failing grade of 57 now. Dolphins initially seemed to be OK, but as more carcasses than usual kept washing up — almost 300 since the spill — the grade fell to 66, compared to a pre-spill 75. Oysters, always under siege, dropped 10 points, crabs dropped 6 points. And the overall food web slid from 70 before the spill to 64 now.
