Reson 8101ER Multibeam Sonar Data from Cruise AHI0902 - Main Hawaiian Islands
Generic Sensor Format (GSF) digital data
http://www.soest.hawaii.edu/pibhmc
Reson 8101ER multibeam Data were collected in
May 21 - June 15, 2009 aboard NOAA Survey
Launch Acoustic Habitat Investigator (AHI) in the Main
Hawaiian Islands at Oahu, Molokai, Lanai, and Maui during
cruise AHI0902. These multibeam data were collected
using SAIC ISS-2000 v 4.0.0.3.0 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 were applied during
post-processing.
Horizontal accuracy is ~5m (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 - 200 m. The
AHI was deployed from shore.
The bathymetric data collection was conducted to
support investigations to minimize the impact of cable routes
to the coral reef environemt and benthic habitat.
The data are being used to provide bathymetric and backscatter
data for areas of interest, and previously unmapped areas around
Oahu, Lanai, Molokai, and Maui and in support of the Department
of Business, Economic Development & Tourism cable routes surveys
efforts for the Main Hawaiian Islands.
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

PCS serial #: 2514
IMU serial #: 203
Controller software: v 3.4.0.0
PCS Firmware: 3.41
Seabird SBE19 CTD:
Serial #: 3029
Last Callibration: 06/17/2008
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.
