Department of Commerce (DOC), National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), Center for Coastal Monitoring and Assessment (CCMA), Biogeography Program 200603 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/ecosystems/coralreef/usvi_nps.aspx This dataset contains a space-delimited ASCII XYZ text file with easting, northing, and depth in meters values for the bathymetry of La Parguera, P.R. and St. Croix, St. Thomas, and St. John in the US Virgin Islands. XYZ values are derived from a 10 m resolution gridding process. 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 2/18/04 to 3/5/04, 2/1/05 to 2/12/05 and 3/21/06 to 4/2/06. Data was acquired with a pole-mounted Reson 8101 ER multibeam echosounder (240 kHz) in 2004 and 2005, and with a hull-mounted Kongsberg Simrad EM 1002 multibeam echosounder (95 kHz) in 2006. 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 swath angle, and was exported as an ASCII XYZ file. 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 projects NF-04-06, NF-05-05 and NF-06-03 during the first, second and third years 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, 2005 and 2006 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. Depth datum is mean lower low water, units are meters and encoding method is explicit depth coordinate included with horizontal coordinates.

This text file 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 to an ASCII XYZ text file. Some positional shifts may have occurred between the original data points and the gridded XYZ values.

XYZ equals northing, easting, and depth in meters. Sourced from CARIS BASE surface. 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 2/18/04 to 3/5/04 and 2/1/05 to 2/12/05 and 3/21/06 to 4/2/06. Multibeam data for 2004 and 2005 were acquired in GSF format with a pole-mounted Reson 8101 ER multibeam echosounder (240 kHz). Multibeam data for 2006 were acquired in .all format with a hull-mounted Kongsberg Simrad 1002 ER multibeam echosounder (95 kHz). Backscatter snippet collection was enabled. Line spacing for acquisition was three times the water depth, and data was retained out to 75 degrees from nadir in 2004 and 2005 and out to 60 degrees from nadir in 2006, 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 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). Process Date Range: 2004, 2005, 2006 NF-04-06/NF-05-05/NF-06-03 HDCS Multibeam Data 2006 Raw GSF and raw Simrad (.all format) were converted and processed using CARIS HIPS v5.4 and 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. Process Date Range: 2004, 2005, 2006 NF-04-06/NF-05-05/NF-06-03 HDCS Multibeam Data 2006 After being submitted to CCMA by the contractor, CARIS HIPS v5.4 and v6.0 were 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 space delimited ASCII XYZ file, with Easting, Northing, and Depth values, using ground position units (NAD83 UTM zone 20N).
