2003 Reson 8101ER Multibeam Sonar Data from Cruise
OES-03-07/AHI-03-07, Data Set Name Guam.
Generic Sensor Format (GSF) digital data
http://www.soest.hawaii.edu/pibhmc/
Reson 8101ER multibeam Data were collected between
22-26 September 2003 (JD 265-269) aboard NOAA Survey Launch Acoustic
Habitat Investigator (AHI) at Guam Island in the Territory of Guam
in the Western Pacific during cruise OES-03-07/AHI-03-07. The AHI
was deployed independently from the NOAA Ship Oscar Elton Sette (OES)
during the cruise.
The multibeam data were logged into data set Guam
and 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 and observed tides from Guam tide gauge
1630000 were applied using SABER postprocessing
software.
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 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:

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.
