Competing Interests

The authors have the following interests. Sample collection during cruises on board R/V Gyre and R/V Ocean Veritas during the Response phase was partly funded by BP as part of the DWH Response effort through funds from BP under the direction of the DWH Unified Area Command (UAC). Christopher Lewis (Industrial Economics, Inc.) reviewed and commented on earlier versions of the manuscript. The study design and scope of work for the present deep-water/soft-bottom benthic study was approved jointly by representatives of the DWH NRDA Trustees and BP. There are no patents, products in development or marketed products to declare. This does not alter the authors' adherence to all the PLOS ONE policies on sharing data and materials, as detailed online in the guide for authors.
