Abstract:

Data from 21 Sampling Stations within the Barataria Bay region of Louisiana. The data record the densities and abundance of two marsh invertebrate species (Uca spp. and Littoraria irrorata) across varying levels of oiling impact due to the Deepwater Horizon Oil Spill. Similar data for 2012-2014 are located in GRIIDC dataset R2.x211.000:0002.
