This dataset contains an ESRI Grid with 2 meter cell size representing the bathymetry of Grammanik Bank south of
St. Thomas, 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 2/1/05 to 2/12/05.
Data was acquired with a pole-mounted Reson 8101 ER multibeam echosounder (240 kHz) and processed by a NOAA
contractor using CARIS HIPS v5.4 software. Data has all correctors applied (attitude, sound velocity) and has
been reduced to mean lower low water (MLLW) using final approved tides and zoning from NOAA COOPS. Data is in UTM
zone 20 north, datum NAD83. The processed CARIS data was used to generate a CARIS BASE surface based on swath
angle. An ASCII XYZ file was exported from the BASE surface and opened in ESRI ArcMap 9 as an XY event. Then the
ArcToolbox conversion tool 'Feature to Raster' was used to generate the final ESRI Grid.
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-05-05 during
the second year of an ongoing NOAA scientific research mission in the US Caribbean to characterize nearshore
coral reef habitats at depths down to 300 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 2005 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.

While the project was conducted to meet IHO Order 1 and 2 accuracy standards, dependant on
project area and depth, all users should independently analyze the dataset according to their own needs and standards
to determine data usability.
This ESRI Grid is sourced from a gridded dataset. The original full-resolution multibeam data was
used to create a downsampled uniform-resolution CARIS BASE (Bathymetry Associated with Statistical Error) surface
grid with a best depth component. The downsampled grid nodes from that depth surface were then exported and used to
generate the ESRI Grid. Some positional shifts may have occurred between the original data points and the
transformed grid.

NF-05-05 ASCII XYZ Multibeam Data
Downsampled ASCII text file containing XYZ values. XYZ = northing, easting, and depth in

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
2/1/05 to 2/12/05, as project number NF-05-05-VI. Multibeam data was acquired in GSF format with a pole-mounted
Reson 8101 ER multibeam echosounder (240 kHz), with options 033, 037, and 040. Reson backscatter snippet
collection was enabled. SAIC ISS 2000 software was used to interface with the Reson system. Line spacing for
acquisition was three times the water depth, and data was retained out to 60 or 70 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, then applied
directly to the raw GSF data. 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-05-05 GSF Multibeam Data
200502
Raw SWMB data in GSF (generic sensor format) format were converted and processed using CARIS
HIPS v5.4 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.
Process Date Range: 200502 - 200511
NF-05-05 HDCS Multibeam Data
200511
After being submitted to CCMA by the contractor, CARIS HIPS v5.4 was used to generate a CARIS
BASE surface (similar to a DTM), based on weighted swath angle, from the processed HDCS data. Then CARIS export
tool "BASE Surface to ASCII" was used to export a comma delimited ASCII XYZ file, with Easting, Northing, and
Depth values, using ground position units (NAD83 UTM zone 20N).
NF-05-05 BASE Surface
200512
The ASCII XYZ file was opened in ArcMap 9 and the 'Display XY Data' option was used to add
the XY data as an event with spatial reference NAD83 UTM zone 20N. Finally, the ArcToolbox 9 conversion tool
"Feature to Raster" was then used to convert the XY event into an ESRI Grid, based on the depth field Z. These
steps were accomplished using an inhouse Arc script which combined these functions and allowed bulk processing.
