2005 Reson 8101ER Multibeam Sonar Data from Cruise
AHI-05-04 - Main Hawaiian Islands
Generic Sensor Format (GSF) digital data
http://www.soest.hawaii.edu/pibhmc/
Reson 8101ER multibeam Data were collected from
13 June-08 July 2005 aboard NOAA Survey Launch Acoustic
Habitat Investigator (AHI) at Niihau, Penguin Bank,
and Molokai in the Main Hawaiian Islands during cruise
AHI-05-04. 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 and
observed tides were applied in postprocessing.
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 - 250 m. The
AHI was deployed from the NOAA Ship Hi'ialakai and
concurrent mapping was done using Simrad EM300 and EM3002D
sonars aboard the ship; metadata for HI-05-04 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

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.

data processed with SAIC SABER processing software on LINUX
operating system computers
Horizontal accuracy is ~5 m as
data were collected using GPS with differential
corrections. Vertical accuracy of multibeam data is
estimated at 1% of water depth; predicted and observed
tidal corrections were applied.
These data are believed to be
logically consistent though no tests were performed

Accuracy
varies with water depth. Predicted tides were applied to the
data in real time and observed tides were applied in post
processing. Tide zoning and offset values were provided
by the NOAA NOS CO-OPS program and predicted and observed
tides for the appropriate tide gauges were downloaded from
the NOAA CO-OPS website. Observed tides were applied based
upon updated tide zoning information provided by NOAA CO-OPS
in 2006. SAIC's ISS2000 and SABER software were used to
produce predicted and observed tide files for each tide zone.
Multibeam data vertical accuracy is ~1% of water depth.
