Project Description

Despite their highly mobile nature, large epipelagic rays were likely exposed to crude oil and chemical dispersant Corexit(TM) from the Deepwater Horizon (DWH) incident in the northern Gulf of Mexico. Aerial surveyors of the immediately impacted area (i.e. SE Louisiana) reported rays swimming through oiled surface waters shortly after the blowout in spring 2010. This particular time-frame (i.e. season) has been shown to support higher than average densities of rays in this region.
