Deep Water Horizon


The Deepwater Horizon oil spill six years ago caused widespread marsh erosion that may be permanent in some places, according to a new analysis of 270 miles of the Louisiana, Mississippi and Alabama coasts. At the hardest-hit of 103 Natural Resource Damage Assessment (NRDA) sites, where oil covered more than 90 percent of plants' stems, widespread die-off of grasses at the marsh edge occurred, followed by up to two years of accelerated erosion as dying plant roots lost their grip on marsh soil.
