Scientists have confirmed that an oil sheen spotted near the site of Deepwater Horizon disaster in the Gulf of Mexico matches the crude that spewed last year from BP’s damaged well.

The real question I think is: is this new oil from the well, or is this the oil that sank from the surface and was floating around around middepth and at the gulf floor?
The day after it enters the water, chemicals in the oil begin to transform, both at the water's surface and farther into the water column. Trace elements lurking in water can speed or slow the process while the sun fuels the breakdown, decomposing even the most complex of oil's components over time. The warmer the water temperature and the more sun exposure, the faster the oil breaks down. Read more: How Oil Breaks Down in Water - Deepwater Cleanup Efforts - Popular Mechanics
During the first few days after a spill, between 20 to 40 percent of oil's mass turns into gases, and the slick loses most of its water-soluble hydrocarbons—what's left are the more viscous compounds that slow down the oil's spread across the water.

If it was dropped to the seabed with corexit or other dispersants, than it would not resurface because it has been chemically altered.
Oil is again bubbling to the surface of the Gulf of Mexico near the epicenter of the 2010 Deepwater Horizon disaster. Reporters from Mobile, Alabama’s Press-Register loaded into a boat Tuesday to inspect the site. Equipped with cameras, the reporters discovered “hundreds of small, circular patches of oily sheen” within a mile of the well. “Floating in a boat near the well site, Press-Register reporters watched blobs of oil rise to the surface and bloom into iridescent yellow patches,” the paper reported Wednesday. “Those patches quickly expanded into rainbow sheens 4 to 5 feet across.” According to the Press-Register, “Each expanding bloom released a pronounced and pungent petroleum smell. Most of the oil was located in a patch about 50 yards wide and a quarter of a mile long.” Petroleum engineers are concerned that oil is leaking from the floor of the Gulf near the sealed well. (Oil trade groups: Drilling deregulation could create 190,000 jobs) Louisiana State University chemist Scott Miles conducted a chemical analysis of the oil to identify its “fingerprint.” Miles said that, “It is possible it could be [from the Deepwater Horizon well] . It’s south Louisiana crude for sure.” BP said in a statement to the Press-Register: “We stand by what we said last week, neither BP nor the Coast Guard has seen any scientific evidence that oil is leaking from the Macondo well, which was permanently sealed almost a year ago.”

i did not know that.
Then it implies something worse.edit on 27-8-2011 by loam because: (no reason given)

Yes, I linked to that one above, but hadn't read the entire thread.

That either
# 1) The cap is no longer working properly, and oil is leaking from that location.
# 2) Oil may be leaking from cracks in the seabed (which we had photographic evidence of as far back as last year).
or # 3) The real conspiracy, that someone took a tanker of oil out there and dumped it to make BP look bad.
Don't worry, # 3 is extremely unlikely, however not impossible.
The United States Coast Guard reports that two remotely operated vehicles deployed to the Macondo 252 well head in the Gulf of Mexico have confirmed there is no oil leaking from the well head. According to the agency, as part of the investigation into recent National Response Center reports of sheen observed in the vicinity of the source of last year’s BP Deepwater Horizon explosion, fire, and ensuing massive oil spill, on August 25th two ROVs were deployed from the Grant Candies to survey the well head. Upon arrival at the well head, the ROVs began an initial, full survey of the well head and vicinity, with a 20-foot radius, looking for evidence of leaking oil. Additionally, a zoom lens was used to examine both the well head and the base of the well head to look for smaller, less obvious signs of leakage. The ROV also visited the two relief well sites. When the survey concluded some ten hours after the ROVs were first deployed, no evidence of leaking oil was found.

If the oil is not coming from the wellhead, nor the relief wells, then where is is coming from?
