2006 Reson 8101ER Multibeam Sonar Data from Cruise
AHI-06-04 - Pacific Remote Island Areas
Generic Sensor Format (GSF) digital data
http://www.soest.hawaii.edu/pibhmc/
Reson 8101ER multibeam Data were collected in
15 March to 8 April 2006 aboard NOAA Survey Launch Acoustic
Habitat Investigator (AHI) at Jarvis Island, Palmyra,
Island, and Kingman Island in the Central Pacific during
cruise AHI-06-04. These multibeam data were collected
using SAIC ISS-2000 software in the Generic Sensor Format
and processed using SABER editing software. Sound velocity
corrections from a Seabird SBE19 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. At
Jarvis Island, Hilo (1617760) predicted tides were used
with a +2.0 time corrector and a range ratio of 1.10.
At Palmyra and Kingman, Honolulu (1612340) predicted tides
were used with a +1 hr 19 min time corrector and a range ratio
of 0.56.
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 10 - 300 m. The
AHI was deployed from the NOAA Ship Hi'ialakai and
concurrent mapping was done using the Simrad EM300
sonars aboard the ship; metadata for HI-06-04 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 R/V AHI (Acoustic Habitat
Investigator), a 8 m (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 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 19 CTD used to measure sound
velocity profiles.
The AHI's equipment serial numbers, software versions and
sensor configuration settings are as follows:
RESON 8101-ER multibeam echosounder
Transducer serial #: 201004
Firmware, dry: 8101-2.07-2D4D
Firmware, wet: 8101-1.06-2F6B
R/V AHI POS/MV Model 320, version 3
PCS serial #: 474
IMU serial #: 203
Controller software: v 2.1
PCS Firmware: 2.16
Seabird SBE19 CTD:
Serial #: 3029
R/V AHI Lever Arm Distances and Alignment Offsets: The R/V
AHI Reference Point (RP) is defined to be the intersection
of the vessel's centerline, the cabin deck and the bulkhead
immediately aft of the transducer. This is marked by a
punch in the deck weld at that location. 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 loaded waterline is defined as the
intersection of the vessel's performance wing with the hull
at the transom.

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