  Description: 
    Abstract: Gridded (40 m cell size) bathymetry of the shelf and slope environments of Howland Island, Pacific Remote
      Isand Areas, Central Pacific. Almost complete bottom coverage was achieved in depths between 8 and 3800 meters. The
      bathymetry dataset includes Simrad EM300, EM3002D, and Reson 8101ER multibeam data collected between Jan. 28-29, 2006.
    Purpose: The data were collected in support of Coral Reef Conservation Program goals to map all shallow (0-30 m) coral
      reefs in US Pacific waters and priority moderate (greater than 30 m) depth areas by 2009. The data are being used to
      provide bathymetric and backscatter data for previously unmapped areas; in support of ecosystem management requirements
      for benthic habitat mapping and location of Essential Fish Habitat; and to study the geologic features of the area.
    Supplemental_Information: Data were collected aboard the NOAA Ship Hiialakai, a 218' United States National Oceanic and Atmospheric Administration
      research ship. The NOAA Ship Hiialakai'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.  Sensor
      configuration for the Hi'ialakai for cruise HI-06-01 is documented in the cruise/multibeam metadata file
      HI0601_MB_Metadata.txt.
      
      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.  Sensor
      configuration for the AHI for cruise AHI-06-01 is documented in the cruise/multibeam metadata file AHI0601_MB_Metadata.txt.

Entity_and_Attribute_Information: 
  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 greater than 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 per cent of water depth.
