In an article written by the University of South Florida, they announced they have detected oil on the Gulf of Mexico floor:
"University of South Florida marine scientists conducting experiments in
an area of the Gulf of Mexico where clouds of oil from the BP spill were
found now have discovered what appears to be oil in sediments of a
vital underwater canyon and observed evidence that the oil has become
toxic to critical marine organisms."
SDIX's Microtox platform was used to detect toxicity, "The bacterial (Microtox) assay indicated that the samples of surface
waters of DHS08, DHS09, and FT1 were toxic - or 3 of the 14 stations
(21.4 percent) had positive results."
