  Description: 
    Abstract: EM1002 and EM120 multibeam Data were collected in October/November 2002
      aboard R/V Kilo Moana between Kauai Island and Lisianski Island in the Northwestern
      Hawaiian Islands (NWHI).  Multibeam data were collected using Simrad Neptune software,
      converted to the Generic Sensor Format, and processed using SABER editing software.
      Sound velocity corrections from CTD's and motion corrections from a POS-MV vertical
      reference were applied to the data in real time.  No tidal correctors were applied
      in real-time or in post-processing. The EM1002 has heave artifacts (~0.6m) in shallow
      bank-top data.
      
      Horizontal accuracy is 20m (no differential GPS correctors applied), vertical accuracy
      is depth dependent (~1% of water depth), WGS84 datum. These data are not to be used for
      navigation. Depths mapped range from 30-5200 meters below sea level.
    Purpose: The data were collected to provide information on the 25, 50, and 100 fm contours
      in the NWHI, which are important for establishing management boundaries for the NWHI
      Coral Reef Ecosystem Reserve.  The data are being used to provide bathymetric and
      backscatter data for previously unmapped areas. The data support ecosystem management
      requirements for benthic habitat mapping and location of Essential Fish Habitat. The
      data are also used to study the geologic features of the area.
    Supplemental_Information: Data were collected aboard the R/V Kilo Moana, a 57 m (186') oceanographic research
      vessel operated by the University of Hawaii, School of Ocean and Earth Science and
      Technology undera a charter agreement with the Office of Naval Research. The R/V
      Kilo Moana survey sensors include a 12 kHz Simrad EM120 sonar and a 95 kHz Simrad
      EM1002 sonar, used to acquire bathymetry and acoustic backscatter imager, a TSS/Applanix
      POS/MV Model 320, which measures time, position, velocity, attitude and heading, and
      expendable bathymetry thermographs (XBT) to acquire sound velocity profiles.
