    • EM304 Water Column Sonar Data Collected During EX2105

    Metadata Updated: November 10, 2022

    From August 15- September 2, 2021, NOAA Ocean Exploration conducted mapping operations on the Blake Plateau within U.S. waters, aiding in closing the gaps within this region. This cruise consisted of a strategic transit from Newport, Rhode Island to the primary working grounds off of the U.S Southeast, aimed at collecting data over previously mapped and potentially new seeps along the edge of the continental shelf. EX-21-05 collected 13,054 square kilometers of bathymetry and associated water column data, 12,989 square kilometers of which were within the U.S. Exclusive Economic Zone and Territorial Sea deeper than 200 m. The cruise concluded in Port Canaveral, FL on September 2, 2021. The exploratory mapping operations conducted during this cruise will provide initial characterization of the region, as well as data to support further exploration with remotely operated vehicles planned for EX-21-07.
