June 8 (Bloomberg) -- Undersea clouds of oil that kill marine life have spread for miles in the Gulf of Mexico from BP Plc’s leaking Macondo well, according to data released by the National Oceanic and Atmospheric Administration today.
Water samples collected by the R/V Weatherbird II vessel have confirmed biodegraded crude oil in two undersea layers as far as 40 nautical miles northeast of BP’s seabed leak, NOAA Administrator Jane Lubchenco said at a press briefing. The vessel’s samples show oil as deep as 3,300 feet in the water, Lubchenco said.
"The bottom line is that yes, there is oil in the water column, it’s at very low concentrations, and we will continue to release those data as soon as they are available,” Lubchenco said at a press conference held jointly with Coast Guard Admiral Thad Allen. “That doesn’t mean that it does not have significant impact.”
Researchers have said the oil slick washing ashore is a small portion of what has leaked and the undersea crude can wipe out marine life while remaining invisible from the surface. Lubchenco said not enough data is available to determine the quantity of oil below the surface. However, she said oil was found at volumes of 0.5 parts per million in the cloud to the northeast of the leak.
