| Title: | Mesophotic and Deep Benthic Communities: Mesophotic Fish and Coral Presence, Absence, and Density Data in the Northeast Gulf of Mexico from 2018-06-28 to 2020-08-04 (NCEI Accession 0276878) |
| Abstract: | Presence, absence and density information for fish and corals in the northeast Gulf of Mexico and the West Florida shelf. Data was collected from three different projects over a two-year period from 2018-2020. The Deepwater Horizon Natural Resource Damage Assessment, Open Ocean Trustee Implementation Group’s Mesophotic and Deep Benthic Communities Restoration: Coral Propagation Technique Development (CPT) Project funded re-analysis of previously collected, separately funded ROV video surveys for acquisition of relevant coral and sponge presence, absence, and density data, and performed a quality assurance/quality check prior to submitting the data to NCEI. Data is formatted into two Excel spreadsheets, one with observations and one with absence data. This data package also includes representative images for each site taken from ROV video. This dataset was generated by William F. Patterson III, University of Florida (UF) during ROV surveys undertaken to monitor Lionfish trap sites and to perform a count of Red Snapper at designated areas. The corresponding video was then analyzed for corals and sponges by Joe Tarnecki at UF. The coral and sponge data in this accession were funded by the Mesophotic and Deep Benthic Communities Restoration: Coral Propagation Technique Development (CPT) project. Members of the CPT Project performed a quality check on the annotations prior to submission to NCEI. |

| Supplementary information: | Submission Package ID: 9X4PWH Data was extracted from multiple studies over a two year period to provide coral abundance and density estimates from ROV sampled locations 40m and greater. Gulf of Mexico Research Initiative (GOMRI) sampling sites (n=13) were from a long term study estimating fish density at reefs impacted by the Deepwater Horizon Oil Spill, "Lionfish Trap" sites (n=108) were from a study focused on trapping lionfish over deepwater mesophotic reefs, "GOM RS Project" (n=58) were from the Gulf of Mexico Red Snapper Count project that had sampling from 2018-2019. Data are derived from ROV transect sampling at sites > 40m. The 2010 Deepwater Horizon (DWH) oil spill released approximately 3.2 million barrels of oil into the Gulf of Mexico (GOM), resulting in quantified injury to an area of over 2,000 km2 (770 mi2) of deep-sea benthic habitats surrounding the wellhead. Damage assessment also documented hydrocarbon exposure to an additional area of over 12,000 km2 extending up the continental slope and onto the continental shelf, as well as substantial losses to corals, other benthic invertebrates, and the associated fish and water column community in an approximately 10 km2 area of mesophotic reef habitats of the Pinnacles Trend off the coast of Mississippi and Alabama. The full extent of damage to mesophotic and deep benthic communities (MDBC) from the DWH oil spill remains unknown, and knowledge gaps regarding MDBC distribution create significant challenges for restoring MDBC communities and achieving restoration goals prescribed by the Final DWH Programmatic Damage Assessment and Restoration Plan / Programmatic Environmental Impact Statement (DWH PDARP / PEIS). |
