[...] According to the chart, “a quarter of the oil is still unaccounted for,” [Steve Murawski, formerly the chief federal fisheries scientist and now a University of South Florida marine science professor] said. “But we know where it is.”
Some of it remains on the bottom of the gulf, buried under a few centimeters of debris and likely to be stirred up again by the creatures that like to burrow in the ocean bottom, he said. Some remains in the marshes of Barataria Bay, La., where research has shown the oil may be causing sickness and death among dolphins. And along parts of the gulf beaches, there’s a strip of “tar pavement” just beneath the sand, Murawski said.
“When the hurricane (Debby) came, it washed the sand away and made it look like a paved highway out there,” he said. That weathered tar “will be with us for a long time.”
The papers published Monday were co-written by National Oceanic and Atmospheric Administration chief Jane Lubchenco, Department of Energy Secretary Stephen Chu and U.S. Geological Survey head Marcia McNutt, among other scientists, and were put out as part of a special issue of the Proceedings of the National Academy of Science.
