BATON ROUGE, La. (AP) - A scientific study has found that heavily oiled areas in Barataria Bay showed twice the normal land erosion rates in the year and a half after the massive BP oil leak in 2010.
The Advocate reports the study found oil killed marsh plants and that led to the higher rates of erosion. However rates of erosion returned to more normal levels after about a year and a half, the study found.
The study was published Monday in the Proceedings of the National Academy of Sciences.
Brian Silliman, associate professor of biology at the University of Florida and lead author of the study, said the normal rate of 5 feet per year of erosion in the bay shoreline doubled to 10 feet per year.
