Oil washed toward shore after the 2010 Deepwater Horizon disaster is a big factor in coastal erosion rates, according to scientists with NASA and the U.S. Geologicial Survey who tracked the changes along the Gulf of Mexico. Their research shows a pattern of dramatic, widespread shoreline loss” along  the Louisiana’s coast in Barataria Bay, located on the western side of the Mississippi River Delta.

The study compared images of the shoreline  taken a year before the oil spill with images taken during a 2.5 year span after the spill. Scientists also compared shoreline losses from storm-induced erosion with losses linked to shoreline oiling. Storm-induced erosion occurred at isolated shoreline sections, but the pre-spill shoreline from 2009 to 2010 was…
