"Two new scientific reports on Tuesday raised fresh fears about the environmental fallout from the world's worst offshore oil spill and questioned government assurances that most of the oil from the ruptured well in the Gulf of Mexico was already gone.
In one of the reports, researchers at the University of Georgia said about three-quarters of the oil from BP's blown-out Macondo well was still lurking below the surface of the Gulf and may pose a threat to the ecosystem. ...
Separately, a study released by University of South Florida scientists said experiments in the northeastern Gulf where so-called plumes or barely visible clouds of oil had been found earlier had turned up oil in sediments of an underwater canyon. The oil was at levels toxic to critical marine organisms."
