Scientists on [August 19] reported results from the first detailed study of a giant plume of oily water near the blown-out BP well - stating that it measured at least 22 miles long, more than a mile wide and 650 feet tall. While other scientists earlier found evidence of plumes in the area, the new data is the first peer-reviewed study about oil lurking in the water, in this case at some 3,000 feet below the surface. It's also the first to offer some details about the size and characteristics of a plume not only vast in size but which remained stable and intact during a 10-day survey last June. Moreover, the study adds to the controversy over how much oil is still in the Gulf ecosystem from the spill. The U.S. government earlier this month estimated that 75 percent of the oil that spewed from the Macondo well had been skimmed, burned or broken up by chemical dispersants and natural microbes in the water. The plume ... shows the oil is persisting for longer periods than we would have expected," lead researcher Rich Camilli said in a statement issued with the study. "Many people speculated that subsurface oil droplets were being easily biodegraded. Well, we didn't find that. We found it was still there."

Each news summary is created according to strict standards. Here's how we do it.
Each summary is created using a consistent editorial procedure. The target length is approximately 16 lines of 11-point Arial text in a 650-pixel-wide column. Up to 25% of a summary may be set in bold to emphasize the most important ideas. Summaries are composed of verbatim excerpts presented in the same sequence as they appear in the original news source, with very minor editorial additions. Where material has been omitted between excerpts, the omission is indicated with ellipses (...). Any words added by an editor for clarity or context appear in [brackets]. Our original news editor was Fred Burks. Tod Fletcher edited most summaries from 2007 through 2014, and Mark Bailey has served as news editor since 2014.
