This image represents a 3 meter resolution backscatter mosaic of the north shore of St. Croix, US Virgin Islands.
NOAA's NOS/NCCOS/CCMA Biogeography Team, in collaboration with NOAA vessel Nancy Foster and territory, federal, and
private sector partners, acquired multibeam bathymetry data in the US Virgin Islands from 3/21/06 to 4/2/06. Data was
acquired with a hull-mounted Kongsberg Simrad EM 1002 multibeam echosounder (95 kHz) and processed by a NOAA
contractor using CARIS HIPS software. Data has all correctors applied (attitude, sound velocity) and has been reduced
to mean lower low water (MLLW) using final approved tides from NOAA COOPS. Data is in UTM zone 20 north, datum WGS84.
The backscatter component of the bathymetry data were geometrically and radiometrically corrected using Geocoder 2.8
software. Acoustic backscatter mosaics are ostensibly an important piece of information when characterizing
surficial seafloor features and delineating benthic habitats.
The project was conducted to meet IHO Order 1 and 2 accuracy standards, dependant on the project area and depth. All
users should individually evaluate the suitability of this data according to their own needs and standards.
This multibeam data was collected as IOCM (Integrated Ocean and Coastal Mapping) project NF-06-03 during the
third year of an ongoing NOAA scientific research mission in the US Caribbean to characterize midshelf and deep water
coral reef habitats at depths down to 1,000 meters. The mission purpose is to better understand the resources within
the surveyed reef habitats, and ultimately develop species utilization models linking physical habitats with
biological information. The multibeam backscatter, multibeam bathymetry, and ground truth video footage collected
during the 2006 mission will be used internally to characterize sea floor topography and to create benthic habitat
maps, helping NOAA meet its mapping commitment to the US Coral Reef Task Force. The resulting publicly-distributed
data is also a contribution to the greater scientific community interested in the USVI seafloor.
Depth datum is mean lower low water, units are meters and encoding method is explicit depth
coordinate included with horizontal coordinates. Vertical Coordinate System information may be found in the

For this project, the Chief Scientist was NOAA/NOS/NCCOS/CCMA's Tim Battista and the Lead
Hydrographer was independent contractor Jay Lazar. Data was collected aboard the NOAA ship Nancy Foster from 3/21/06
to 4/5/06, as project number NF-06-03. Multibeam data was acquired in Simrad .all format with a hull-mounted
Kongsberg Simrad EM 1002 multibeam echosounder (95 kHz). Simrad backscatter snippet collection was enabled. Line
spacing for acquisition was three times the water depth, and data was retained out to 60 degrees from nadir,
depending on project area. Heave, roll, pitch and heading correctors were collected using an Applanix POS/MV Model
320 inertial measurement unit (IMU) and associated Trimble GPS antennas. Sound velocity profiles were acquired with
a Seabird Electronics SeaCat SBE19P CTD profiler and processed using Seabird Seaterm software. Positioning was
obtained using Northstar 941X GPS receivers with differential correctors from U.S. Coast Guard CORS beacon Isabel,
Puerto Rico. Data was reduced to Mean Lower-Low Water (MLLW) using final approved tides from NOAA COOPS, based on
National Water Level Observation Network (NWLON) primary tide stations at Charlotte Amalie, VI (9751639) and Lime
Tree Bay, VI (9751401).
NF-06-03 Multibeam Data
2006
Raw SWMB data were converted and processed using CARIS HIPS v6.0 software, resulting in a CARIS
HDCS format dataset with all correctors applied. Attitude and SWMB data was cleaned of fliers, and SWMB data was
reviewed in subset mode by a NOAA contractor.
NF-06-03 HDCS Multibeam Data
2006
Acoustic backscatter mosaics are ostensibly an important piece of information when characterizing
surficial seafloor features and delineating benthic habitats. The multibeam backscatter data were corrected for
geometric and radiometric distortions using Geocoder 2.8. In particular, the following corrections were applied
where appropriate and when artifacts were evident: AVG Trend, TX Power and RX Gain, Area Correction, Spreading,
Slant-Range and Extracted Beam Pattern. As no theoretical beam pattern for the Kongsberg Simrad 1002 system exists,
it was extracted from a mapped area that was flat and had a relatively uniform (sandy) substrate. Individual lines
were also truncated based on ping number and/or angle of incidence where appropriate. The final mosaics were
exported as geotiffs, ASCII and XYB files (i.e., X,Y locations in WGS 1984 UTM Zone 20N and Backscatter values as
measured in decibels dBs).
