Data Set Description: This is a subset of the Deep Sea Coral Research and Technology Program’s National Database. The 2019 Southeastern U.S. Deep-sea Exploration was a 43-day, two-part expedition led by the NOAA Office of Ocean Exploration and Research (OER) on NOAA Ship Okeanos Explorer. Its purpose was to collect critical baseline information about largely unexplored deepwater areas of the Southeastern U.S. continental margin. It addressed scientific themes and priority areas suggested by scientists and managers from NOAA, management agencies in the region, other federal agencies, and the ocean science community. During this expedition off the coasts of South Carolina, Georgia, and Florida, the expedition team mapped and explored a variety of habitats and features, including coral mounds, terraces, slopes, escarpments, and boulders. The data represent observations of deep-sea corals and sponges observed during deepwater ROV surveys by NOAA Ship Okeanos Explorer off of the Southeastern United State in the following localities: Southern Blake Plateau, Stetson Mesa, Million Mounds East, Stetson Mesa West, Stetson Mound Field 01, Stetson Mound Field 02, Isolated Mound, Central Blake Plateau, Habitat Response 01, Miami Terrace, Key Largo Deep, Pourtales Terrace, Key West Deep, and Berg Bits. This research and exploration cruise was conducted between November 1 through November 19, 2019. Changes to the original dataset may have been made to conform to the National Database Schema and for quality control purposes.
