  Description: 
    Abstract: Gridded bathymetry shelf, bank and slope environments of
      Pagan Island, CNMI. Bottom coverage was achieved in depths
      between 3 and 3634 meters, but this 10m grid contains data
      to only 800 m. The netCDF and Arc ASCII grids include multibeam
      bathymetry from the Simrad EM300 and Reson 8101 multibeam sonars
      collected as of June 2007 by the NOAA Coral Reef Ecosystem
      Division. The sonar frequencies are 30 and 240 kHz respectively.
    Purpose: These netCDF and ASCII grids were created using data gathered
      from multibeam soundings for use as a planning and reference
      document. The data are also being used for benthic habitat
      mapping, for locating Essential Fish Habitat, and for studying
      geologic features of the area. Refer to supplemental information
      for description of instrument and survey.
    Supplemental_Information: Multibeam data were collected aboard the NOAA Ship Hi'ialakai, a
      218' United States National Oceanographic and Atmospheric
      Administration research ship. The NOAA Ship Hi'ialakai's survey
      sensors include a 30 kHz Simrad EM300 sonar and a 300 kHz Simrad
      EM3002d sonar, which provide bathymetry and imagery data, a
      TSS/Applanix POS/MV Model 320, which measures position, velocity,
      attitude and heading, and a Seabird SBE 9/11 plus CTD used to
      measure sound velocity profiles.
      
      Multibeam data were also collected aboard the R/V AHI (Acoustic
      Habitat Investigator), a 25' survey launch owned and operated by
      the NOAA Pacific Islands Fisheries Science
      Center in Honolulu, HI. The R/V AHI's survey sensors include a
      240 kHz RESON 8101-ER sonar providing bathymetry and imagery
      data, a TSS/Applanix POS/MV Model 320 which measures position,
      velocity, attitude and heading, and a Seabird SBE 19 CTD used to
      measure sound velocity profiles.

    Process_Step: 
      Process_Description: Multibeam swath files are acquired on and around each island and
        bank in the Generic Sensor Format (GSF) and are edited on a swath
        by swath basis using SAIC's SABER editing software. The edited
        swath files are then combined into a Pure File Magic (PFM) format
        with a defined grid cell size (10 m) in SABER and area based
        editing is performed. The edited PFM is then exported as X,Y,Z
        data with a value at each grid node. The X,Y,Z data are then
        and gridded using nearneighbor, a Generic Mapping Tools (GMT)
        algorithm that converts an ASCII or binary table to a netCDF grid
        file format. NetCDF grids are then converted to an ArcGIS ASCII
        file format using LINUX/UNIX commands in combination with GMT.
        GMT is an open source collection of tools for manipulating
        geographic data sets. Additional information about GMT can be
        found at: http://www.soest.hawaii.edu/gmt and additional
        information about the multibeam data processing is recorded in
        the cruise metadata.

  Overview_Description: 
    Entity_and_Attribute_Overview: Depth values are real values based on the average of the
      soundings that fell within the extracted grid cells. The number
      of soundings per grid cell range from >1000 soundings in shallow
      depths to as few as 20 soundings in deeper areas.  A total error
      budget for these data have not been developed. Therefore, the
      accuracy of depth measurements should be considered to be within
      1 meter.
