BP exec: No large concentrations of underwater oil

NEW ORLEANS (AP) - BP Chief Operating Officer Doug Suttles continues to insist that no massive underwater oil plumes in "large concentrations" have been detected from the spill in the Gulf of Mexico.

Suttles' comments came Wednesday morning on network news shows, a day after the government said water tests confirmed underwater oil plumes from the oil spill, but that concentrations are "very low."

Suttles told NBC's "Today" show that it "may be down to how you define what a plume is here."

NOAA Administrator Jane Lubchenco said Tuesday that the tests conducted at three sites by a University of South Florida research vessel confirmed oil as far as 3,300 feet below the surface 42 miles northeast of the well site.
