2006 EM300 and EM3002D Multibeam Sonar Data from Cruise
Hi'ialakai HI-06-01 - Pacific Remote Island Areas
Generic Sensor Format (GSF) digital data
http://www.soest.hawaii.edu/pibhmc/
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.
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.
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.

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.

corrections. Vertical accuracy of multibeam data is
estimated at 1% of water depth; predicted tidal corrections
were applied.
These data are believed to be
