Department of Commerce (DOC), National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), Center for Coastal Monitoring and Assessment (CCMA), Biogeography Branch 201010 1st raster digital data Silver Spring, MD NOAA's National Ocean Service (NOS), National Centers for Coastal Ocean Science (NCCOS) http://ccma.nos.noaa.gov/products/biogeography/usvi_nps/default.aspx This georeferenced RGB image represents 1 meter resolution bathymetry of a sharply sloping swath of the St. John Shelf, a selected portion of seafloor south of St. John, USVI, derived from data collected in March and April 2010. This image is also vertically exaggerated by a factor of 1, and sun illuminated where the azimuth = 45 degrees and angle = 40 degrees. NOAA's NOS/NCCOS/CCMA Biogeography Branch, in collaboration with NOAA vessel Nancy Foster and territory, federal, and private sector partners, acquired multibeam bathymetry data south of St. Thomas and St. John, USVI, from 3/18/10 to 4/6/09. Data was acquired with a hull-mounted Kongsberg Simrad EM 1002 multibeam echosounder (95 kHz) for water depths greater than 75 meters, and with a moon pool flange-mounted Reson 7125 multibeam echosounder (dual frequecy, 200/400 kHz) for water depths of up to 75 meters. It was 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 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 CUBE, which was then pushed through the CARIS export tool "BASE Surface to Image" to create the final 8-bit GeoTIFF. 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-10-03 during the seventh year of an ongoing NOAA scientific research mission in the US Caribbean to characterize nearshore to 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 2004-2010 missions 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.

This GeoTIFF is sourced from a CARIS 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. See Data Acquisition and Processing Report (DAPR) for NF-10-03.

For this project, the Chief Scientist was NOAA/NOS/NCCOS/CCMA's Tim Battista and the Lead Hydrographer was independent contractor Mike Stecher. Data was collected aboard the NOAA ship Nancy Foster from 3/18/10 to 4/6/10. Multibeam data were acquired in .all format with a hull-mounted Kongsberg Simrad 1002 ER multibeam echosounder (95 kHz) for water depths greater than 75 meters and in .hsx format with a moon pool flange-mounted Reson 7125 multibeam echosounder (dual frequecy, 200/400 kHz) for water depths of up to 75 meters. 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 for both the EM1002 and the Reson 7125. Heave, roll, pitch and heading correctors were collected using an Applanix POS/MV Model 320 V4 inertial measurement unit (IMU) and associated Trimble GPS antennas. Sound velocity profiles were acquired with a Seabird Electronics SeaCat SBE19P CTD profiler and a Reson SVP 70 and processed using NOAA's Velocwin V8.85 software, then applied directly to the raw data. Positioning was obtained using Trimble Zephyr GPS receivers and an auxiliary Trimble DSM 132 DGPS 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). NF-10-03 HDCS Multibeam Data 2010 Raw .hsx and .all data were converted and processed using CARIS HIPS v7.0 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-10-03 HDCS Multibeam Data 2010 After being submitted to CCMA by the contractor, CARIS HIPS v7.0 was used to generate a CARIS BASE surface (similar to a DTM), based on CUBE (Combined Uncertainty and Bathymetry Estimator), from the processed HDCS data. Then CARIS export tool "BASE Surface to Image" was used to export an 8 bit GeoTIFF in the coordinate system NAD83 UTM Zone 20N.
