The Southeast Fisheries Science Center Mississippi Laboratories has collected standardized ichthyoplankton resource surveys in the Gulf of Mexico since 1982. Several surveys are conducted throughout the year and focus on different areas of the northern Gulf of Mexico. The spring survey is an offshore survey that samples primarily from the edge of the continental shelf to the Economic Exclusion Zone, while the summer and fall surveys primarily focus on the continental shelf. Typically, the fall plankton survey is selected as the source of larval abundance data because of its spatial coverage, as opposed to surveys in the summer which did not adequately cover the eastern Gulf of Mexico prior to 2008. Data from these standardized surveys were provided to the Natural Resources Damage Assessment (NRDA) to support assessment of the environmental impacts of the Deepwater Horizon oil spill which occurred in the Gulf of Mexico in 2010.
