• Abstract:
• • EM300 and EM3002D multibeam Data were collected
    from 15 Jan - 6 Feb 2006 aboard NOAA Ship Hi'ialakai at
    Johnston Island, Howland Island, and Baker Island in the
    Central Pacific during cruise HI-06-01 These multibeam
    data were collected using SAIC ISS-2000 software in the
    Generic Sensor Format and processed using SABER editing
    software. Surface sound velocity values were supplied by a
    Seabird SBE-45 MicroTSG and a SBE-38 remote temperature
    probe. Sound velocity corrections from a Seabird 911 CTD
    sensor and motion corrections from a POS-MV vertical
    reference were applied to the data in real time. Predicted
    tides were applied to the data in real time: for Johnston
    Island predicted tides from the NOS CO-OPS web site were
    used; for Baker and Howland Islands predicted tides based
    upon the Honolulu tide station (1612340) with a time corrector
    of 3 hrs 48 min and a range ratio of 3.91.
    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 ~20 - 4720 m.
    Concurrent mapping was done by the R/V AHI in water depths
    ranging from 3-250 m with the data set being AHI-06-01;
    metadata for AHI-06-01 are submitted separately.
• 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 (> 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 Hi'ialakai, a 68 m
    (218') United States National Oceanographic and Atmospheric
    Agency (NOAA) research ship. The NOAA Ship Hiialakai's
    survey sensors include a 30 kHz Simrad EM300 sonar and a
    300 kHz Simrad EM3002d sonar, which measures bathymetry and
    acoustic backscatter imagery, a TSS/Applanix POS/MV Model
    320, which measures time, position, velocity, attitude and
    heading, and a Seabird SBE 9/11 plus CTD used to measure
    sound velocity profiles.
    The Hi'ialakai's equipment serial numbers, software
    versions and sensor configuration settings are as follows:

    Hi'ialakai Lever Arm Distances and Alignment Offsets: The
    Hi'ialakai's Reference Point (RP) is a granite block
    situated 1.222 m starboard of the ship's centerline, 1.23 m
    above the ship's baseline/datum on the keel. The RP is
    located under the forward deck, in the ship's laundry room.
    The ship's sensors, the sonar systems and permanent
    benchmarks are measured with respect to the RP. Positive X
    means the point is forward of the RP, positive Y means the
    point is to starboard of the RP, positive Z means the point
    is below the RP. The survey waterline is defined to be at
    the 15' draft mark on the vessel's starboard side.
