This photo-identification collection is intended to provide a visual reference to commonly observed deep-sea corals in the Southeast United States, Gulf of Mexico, and U.S. Caribbean, as a consensus aid for taxonomic identification of these organisms. This document also aims to provide an effectual representation of the diversity of coral fauna encountered in the deep-sea of this greater U.S. Southeast region (defined here as > 200 m deep) by the NOAA Office of Ocean Exploration and Research, using remotely operated vehicle Deep Discoverer in years 2017-2019.
