Gulf spill's effects 'may not be seen for a decade' (Jason Palmer)

Feb. 20, 2011 -- WASHINGTON (BBC) -- The 2010 Deepwater Horizon oil spill "devastated" life on and near the seafloor, a marine scientist has said.

Studies using a submersible found a layer, as much as 10cm thick in places, of dead animals and oil, said Samantha Joye of the University of Georgia.

Knocking these animals out of the food chain will, in time, affect species relevant to fisheries.

She disputed an assessment by BP's compensation fund that the Gulf of Mexico will recover by the end of 2012.

Millions of barrels of oil spewed into the sea after a BP deepwater well ruptured in April 2010.
