Oil spills underreported in Gulf of Mexico
But watchdog groups say that the system's reliance on selfreporting means its data are fundamentally flawed.
One of those groups is SkyTruth of Shepherdstown, West Virginia, founded by geologist John Amos in 2001 to monitor the effects of human activity on the environment using remotesensing and mapping technologies. Amos monitored satellite images of the Gulf of Mexico during the Deepwater Horizon disaster, noticed a separate slick, and traced it to the former Taylor Energy platform 23051.
According to NRC reports analyzed by Amos, an average of 14 gallons per day had been spilling from that rig for several months, says Amos. "But our image analysis shows the leak rate must be greater, possibly by a factor of 10." Assuming oil needs to be at least 1 micrometre thick to create a visible sheen, he explains, and assuming that an oil slick that thin has a 72hour lifespan at the surface, a leak of 14 gallons per day could only create a visible sheen 1.6 kilometres long by 91 metres wide. "We repeatedly observed, and NRC reports describe, slicks much larger," Amos says.
Small claims It is a common problem. Amos had previously found a slick nearly 34 km long that was blamed on a spill of just 7 gallons (See Skytruth's reports).
Then, in March 2011, oil washed ashore on Grand Isle, Louisiana. Workers at the Department of Wildlife and Fisheries traced the spill to an apparent source at West Delta Block 117, about 32 km to the south west. AngloSuisse Offshore Partners (ASOP) of Houston, Texas, had reported three discharges from its Platform E there, totalling less than 5 gallons. But, says Amos, "enough came ashore that the Coast Guard had to mount a cleanup response, which certainly suggests more than a few gallons".
The Coast Guard collected oil samples from the ASOP well and the slick, which were sent to Louisiana State University in Baton Rouge for chemical fingerprinting. Ed Overton, professor emeritus at the university's School of the Coast and Environment, says the samples matched. "All oil contains the same molecular structures, but oil from different sources contains different levels of hundreds of various compounds,[url=http://www.xantrex.cc]louis vuitton handbags[/url]," says Overton, who developed the first methods for analyzing components as a method of "fingerprinting" oil samples in the late 1970s, and has continued to be involved in refining the technology1.
ASOP did take responsibility for the cleanup, which had been largely completed by 6 April, but the company did not return phone calls from Nature requesting comment.
Amos thinks that the Taylor and Grand Isle incidents illustrate the reporting system's flaw. "There is a strong incentive to underreport incidents. Who is going to get in a helicopter and fly 50 miles offshore for a 2gallon spill? You report so you won't get fined, but report small because you know that will keep everybody behind their desks. We need some kind of independent verification."
The Coast Guard conducts a telephone investigation of every report, according to Petty Officer Nathan Thompson, and determines an appropriate course of action on the basis of that. There is no threshold amount that triggers a response. "It depends on the location, the reporting party and other factors," Thompson says. "If a company had a history of a lot of spills, or if a spill occurred in a more environmentally sensitive area, we'd probably go out. Sometimes we have to prioritize. In Louisiana, we get a lot of reports of spills from unknown sources, and we go out to those every single time."
Guessing game Overton also suspects that spills are routinely underestimated given that fines are linked to volume, but points out that estimating spill volume is not an exact science. "Sheens can cover a lot of area and not represent much oil," he explains. "We need research on better spectral methods to estimate the thickness of sheens."
More accurate data are vital as offshore drilling ramps back up postDeepwater Horizon, Amos says. "NRC reports are the only comprehensive offshore spill database. But if the government and citizens rely on them to know how much pollution is caused by offshore oil and gas production, our drilling policy is based on fundamentally inaccurate data."
Accurate or not, the data are difficult to use, says Eric Schaeffer, former head of civil enforcement at the US Environmental Protection Agency and now director of the nonprofit organization the Environmental Integrity Project, headquartered in Washington DC. "The data are pretty scattered, nomenclature is not consistent. At the time of release, you don't necessarily know how much has spilled, yet have an immediate obligation to report. But there isn't correction and updating of information later. Simple things such as spelling out how you did the numbers would be really valuable."
Carrie Beth Lasley, a researcher at the University of New Orleans Center for Hazards Assessment, Response and Technology, adds that mandatory annual inspections of platforms or at the very least after a hurricane are also needed.
Amos would like someone to monitor satellite images to identify unreported and underreported spills. "We were able to document the leak from the Taylor platform because, during the BP spill, multiple satellite imaging systems were trained on that part of the Gulf on a daily basis," he says. "But once BP was plugged, the data stream slowed to the normal daily trickle. Satellites are overhead all the time, but only on when a paying customer wants an image."
The hardware and personnel for a Gulfwide monitoring system already exist, he notes, at the University of Miami's Center for Southeastern Tropical Advanced Remote Sensing in Florida. "We have tremendous assets we aren't using, and that's a shame."
As part of an effort to rectify this, on 19 April, SkyTruth announced it was forming a consortium with North Carolinabased SouthWings, a nonprofit organization of private pilots, and Waterkeeper Alliance, a worldwide organization promoting clean water, to monitor pollution. $30 coach handbag,gucci handbag,prada handbag, $12sunglasses,$9 caps.
