    • NCCOS Mapping: Geospatial products of water depth, acoustic backscatter, and ROV data collected from NOAA Ship Nancy Foster in the Dry Tortugas, Florida Keys National Marine Sanctuary from 2021-03-18 to 2021-04-10 (NCEI Accession 0290189)

    Metadata Updated: December 1, 2025

    Multibeam and acoustic backscatter data collected from NOAA Ship Nancy Foster from 2021-03-18 to 2021-04-10. Data was collected using a Kongsberg EM2040. Bathymetry grids were created using CARIS HIPS and SIPS software, and corrected to Mean Lower Low Water (MLLW). Backscatter mosaics were created using Fledermaus Geocoder Toolbox (FMGT). Data were acquired and processed to meet IHO Order 1 specifications. Survey depths vary from 40m to 190m. Data are available in one and two meter resolutions. During the field mission, a Mohawk 18 Remotely Operated Vehicle (ROV), operated by the University of North Carolina Undersea Vehicles Program collected HD photo and ground validation video. Video data is not included with this dataset.
