  Description:
    Abstract: Gridded bathymetry (10m) of Kahoolawe Island, Hawaii, USA.
    The data include multibeam bathymetry from the EM120, EM122,  EM1020, and EM1002 multibeam sonar collected
    by the Hawai‘i Undersea Research Laboratory of the University of Hawaii in depths between -30 and  -1300 meters.
    Data processing was done for distribution by the NOAA Coral Reef Ecosystem Division. 
    Purpose:
      These netCDF and ASCII grids were created using data gathered from multibeam soundings for documentation
      and for use as a planning and reference document. Further data were collected to fill gaps in the
      existing bathymetry.
      Refer to supplemental information for description of instrument and survey.
    Supplemental_Information:
      Data were collected aboard the R/V Kilo Moana, a 186' Waterplane Area Twin Hull (SWATH) vessel owned by the U.S. Navy and operated by the University
      of Hawaii Marine Center. The R/V Kilo Moana's survey sensors include a Simrad EM710: 70-100 kHz swath mapping, 10-1800 m depth range
      Multibeam and a Simrad EM122: 12 kHz swath mapping, 300-11,000 m depth range which measure bathymetry and
      acoustic backscatter imagery, a TSS/POS/MV 320 Model which measures time, position, velocity, attitude and
      heading, and a Seabird **** CTD used to measure sound
      velocity profiles. Specific equipment configurations are documented:

     Process_Description: 
       Multibeam swath files are acquired 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 
       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
      this survey has not been developed. Therefore, the accuracy of depth
      measurements should be considered to be within 1 meter.

         These data can be downloaded as either a 2-D binary netCDF raster
         grid or an ArcGIS ASCII text file. The netCDF grid
         is the default grid file format used by GMT (Generic Mapping 
         Tools), which created this file. More information can be located 
         at http://www.soest.hawaii.edu/gmt/and 
         http://www.unidata.ucar.edu/software/netcdf/. The Arc ASCII file, 
         for use in ESRI's (http://www.esri.com) GIS software, can be 
         converted to an Arc Raster Grid using ArcToolbox ASCII to Raster 
         conversion tool.
