            NGDC is the US national archive for multibeam bathymetric data and 
            presently holds over 1.6 million nautical miles of ship tracklines 
            (660 surveys) received from sources worldwide.

      Abstract: 
        High-quality, full coverage, multibeam bathymetry and 3.5-kHz subbottom 
        seismic data were collected along the U.S. lower continental margin. 
        Raw Simrad EM120 multibeam bathymetry and backscatter data together 
        with position, vehicle, ship orientation, water-column sound-speed are 
        incorporated in the raw datagrams. In addition, Knudsen 320 B/R 
        3.5-kHz subbottom seismic data were collected in SEG-Y format and 
        gravity was collected in ASCII format. This dataset described here is 
        the multibeam bathymetry data. This data set is part of a larger set 
        of data called the the MultiBeam Bathymetric Data Base (MBBDB) where 
        other similar data can be found at 
        http://map.ngdc.noaa.gov/website/mgg/multibeam/.
      Purpose: 
        The National Oceanic and Atmospheric Administration (NOAA), on behalf of the United States Government, has a requirement to carry out surveys of specific regions on the continental margin (slope and rise) in the northern Atlantic Ocean in order to obtain multibeam bathymetry and co-registered calibrated acoustic backscatter.  These data are required to support a potential claim for extended jurisdiction by the United States under United Nations Convention on the Law of the Sea (UNCLOS) Article 76.   The requirement is for the collection and processing of high quality, full-coverage multibeam sonar data in water depths of approximately 2000 to 5500 m in order to precisely define the location of the 2500-m isobath and the "foot of the slope" as defined under UNCLOS Article 76.  As part of their NOAA-funded research program, University of New Hampshire (UNH) researchers oversaw data acquisition, processing and archiving of the data collected during the cruise.

    Attribute Accuracy: 
      Attribute Accuracy Report: 
        A Kongsberg Maritime Simrad EM120 12-kHz multibeam sonar was used with 
        effective beam widths no greater than 1 degree x 1 degree (fore-aft x 
        athwart ships) at -3 dB, with swaths of about 3.4 times water depth in 
        water depths between 4000 and 6000 m, with depth accuracies within 
        each swath of better than +/- 0.5% of water depth at these depths. All 
        data meets this specification. Descriptions of the systems and offsets 
        applied can be found within the cruise report at 
        http://www.ccom.unh.edu/law_of_the_sea.html reports.

        Horizontal Positional Accuracy Report: 
          Horizontal positioning of the vessel was determined using Fugro SkyFix 
          Wide Area Differential-aided DGPS integrated into an IXSEA PHINS 
          inertial navigation and motion-sensing system. Positioning is 
          accurate to better than 5 meters (at 95% confidence) during all 
          surveying. All positioning is referenced to the WGS84 Datum.
      Vertical Positional Accuracy: 
        Vertical Positional Accuracy Report: 
          Depth errors (at the 95% confidence level) are smaller than +/-0.5% of 
          the observed water depth as determined by cross lines.
