        abstract:  This data set is part of a larger set of data called the Multibeam Bathymetry Database (MBBDB) where other similar data can be found at https://maps.ngdc.noaa.gov/viewers/bathymetry/
        purpose:  The intent of these data is to make high-resolution bathymetry available to the public for a wide variety of uses such as research and earth science analysis. These data are not intended to be used for navigation. Nautical charts produced and certified by NOAA should be used for navigational purposes. For more information on NOAA's nautical charts, go to NOAA's Office of Coast Survey website at: http://chartmaker.ncd.noaa.gov.

            statement:  Multibeam data is collected by vessels of varying characteristics including ships, small boats, remotely operated vehicles (ROVs), and autonomous underwater vehicles (AUV). The NOAA National Centers for Environmental Information (formerly NGDC) archive raw data, processed data, and associated products. All data and products are made available to the public via NCEI's map services and search interfaces.

            description:  Seabeam 2112 (12 Khz) swath bathymetric sonar system. The system, originally used for high accuracy (Seabeam Classic) charting of the U.S. Exclusive Economic Zone (EEZ), is capable of hydrographic charting and seafloor acoustic backscatter imaging in water depths of 50 to 11,000 meters with up to 151 beams. Swath coverage (75 percent of water depth) varies as a function of depth, from 150 degrees at 1,000 meters, to 120 degrees at 5,000 meters, and 90 degrees at 11,000 meters, with a resolution of two degrees. The system regularly operates in 4000+ meters of water but is effective in shallower applications (less than 500m).
