Federal scientists are reporting the best possible scenario for BP's leaked oil: Microbes are munching the underwater oil, but not robbing the Gulf of Mexico of much needed oxygen or creating so-called "dead zones."

More Gulf waters are reopening to fishermen, and government officials say seafood cleared for sale has been thoroughly inspected. Whether consumers are buying those assurances remains to be seen.

A 22-mile-long invisible mist of oil is meandering far below the surface of the Gulf of Mexico, where it will probably loiter for months or more, scientists reported Thursday in the first conclusive evidence of an underwater plume from the BP spill.

The oil is there, at least 22 miles of it. You just can't see it.

Researchers are warning that the Gulf of Mexico oil spill is a bigger mess than the government claims and that a lot of crude is lurking deep below the surface, some of it settling perhaps in a critical undersea canyon off the Florida Panhandle.

With a startling report that some researchers call more spin than science, the government said Wednesday that the mess made by the BP oil spill in the Gulf of Mexico is mostly gone already.
