There are multiple underwater oil plumes in the area surrounding BP’s broken wellhead off the coast of Louisiana, but so far their concentrations seem to be “very low,” according to a report released Tuesday by NOAA. Scientists analyzed water samples collected by the University of South Florida’s R/V Weatherbird II between May 22 and 28. Samples collected by the R/V Weatherbird II came from three stations located 40, 45 and 142 nautical miles from the well head, respectively. Sampling depths ranged from 50 to 1,400 meters.
