CRED EM300 and EM3002D Multibeam Sonar Data from Cruise Hi'ialakai hi0804 - Northwestern Hawaiian Islands, 2008
Generic Sensor Format (GSF) digital data
http://www.soest.hawaii.edu/pibhmc/cms/data-by-location/northwest-hawaiian-islands/
EM300 and EM3002D multibeam Data were collected from
2 - 29 May 2008 aboard NOAA Ship Hi'ialakai at
Necker Island, French Frigate Shoals, and Brooks Bank in the
Northwestern Hawaiian Islands, during cruise hi0804.
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 SBE 9/11 plus CTD 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.
Horizontal accuracy is 20 m (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 ~20-3000 m.
Concurrent mapping at French Frigate Shoals was done by
the R/V AHI in water depths ranging from ~10-350 m with
the data set being ahi0804; (metadata for ahi0804 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 Hiialakai, 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.

Hiialakai Lever Arm Distances and Alignment Offsets:
The Hiialakai'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.

Horizontal accuracy is ~20 m as
data were collected using GPS with no differential
corrections. Vertical accuracy of multibeam data is
estimated at 1% of water depth; predicted tidal corrections
were applied.
These data are believed to be
logically consistent though no tests were performed

varies with water depth. Predicted tides were applied to the
data in real time. Tide zoning and offset values were provided
by the NOAA NOS CO-OPS program and predicted tides for the
appropriate tide gauges were downloaded from the NOAA CO-OPS
website. SAIC's ISS2000 and SABER software were used to
produce predicted tide files for each tide zone.
Multibeam data vertical accuracy is ~1% of water depth.
