The purpose of the data is to support Florida Keys National Marine Sanctuary (FKNMS) benthic habitat mapping and research planning efforts for improved spatial and fishery ecosystem management. The data consists of multibeam data sets that contain bathymetric and in some areas backscatter data. All data products produced are supplied as ready to use products for a Geographic Information System (GIS) and CARIS, projected in Universal Transverse Mercator (UTM) 17 N, North American Datum 1983 (NAD83) and vertically reduced to Mean Lower Low Water (MLLW). |

<DIV STYLE="text-align:Left;font-size:12pt"><P><SPAN><SPAN>In Summer 2015, National Oceanic and Atmospheric Administration (NOAA) Center for Coastal Fisheries and Habitat Research (CCFHR) division contracted Geodynamics services for a complete processing and reviewing of multibeam sonar data collected on the NOAA Ship Nancy Foster (NF) and Thomas Jefferson (TJ) from the years 2004-2016. The seabed elevation and acoustic imagery data (backscatter) were collected using multibeam echosounders (MBES) on the respective ships. The data were preliminary processed and corrected for motion, sound speed, and other major artifacts before assessment by Geodynamics. However, the data were only semi-cleaned, contained various artifacts, and converted with the real-time tide. Therefore, Geodynamics was contracted to complete a full review of the data and apply a NOAA zoned definition file (ZDF) to permit CCFHR’s later use of the data for characterizing Florida Keys National Marine Sanctuary (FKNMS) and adjacent areas bottom habitats. The corrected bathymetry base surface will be used to interpret the seafloor topography habitat types and extend the range of existing habitat map products that were created by manual interpretation of satellite imagery. The acoustic imagery (backscatter) aspect of the data will help further this interpretation. However, Geodynamics was not responsible for processing backscatter data but were responsible to ready the backscatter data for eventual processing. This version of the FKNMS Digital Atlas also contains multibeam data collected on the NOAA Ship Nancy Foster during the summer of 2018, and multibeam data collected in 2018 around the Marquesas on small vessels under contract to NOAA, OCS.</SPAN></SPAN></P></DIV> |
