Department of Commerce (DOC), National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), Center for Coastal Monitoring and Assessment (CCMA), Biogeography Program 200711 1st remote-sensing image 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 10 meter resolution bathymetry of Abrir La Sierra Bank, Puerto Rico. 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 Team, in collaboration with NOAA vessel Nancy Foster and territory, federal, and private sector partners, acquired multibeam bathymetry data in Puerto Rico from 4/14/07 to 4/24/07. Data was acquired with a hull-mounted Kongsberg Simrad EM 1002 multibeam echosounder (95 kHz) and a Reson 8124 multibeam echosounder 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 and zoning from NOAA COOPS. Data is in UTM zone 19 north, datum NAD83. The processed CARIS data was used to generate a CARIS BASE image surface based on swath angle. 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-07-06 during the fourth year of an ongoing NOAA scientific research mission in the US Caribbean to characterize midwater and deep water coral reef habitats at depths of up 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 2007 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 US Caribbean seafloor. Depth datum is mean lower low water, units are meters and encoding method is explicit depth coordinate included with horizontal coordinates.

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. See Data Acquisition and Processing Report (DAPR) NF-07-06.

For this project, the Chief Scientist was NOAA/NOS/NCCOS/CCMA's Tim Battista and the Lead Hydrographer was independent contractor Mike L. Stecher. Data was collected aboard the NOAA ship Nancy Foster from 4/14/2007 and 4/24/2007. Multibeam data for 2007 were acquired in .all format with a hull-mounted Kongsberg Simrad 1002 ER multibeam echosounder (95 kHz) for depths greater than 75 meters and a in .xtf format with a Reson 8124 multibeam echosounder (200 kHz) for depths less than 75 meters. Backscatter snippet collection was enabled. Line spacing for acquisition was 3.5 times the water depth, and data was retained out to 55 degrees from nadir, for the Simrad, and 60 degrees from nadir, for the Reson, depending on project area. 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 SBE-911 and SBE-19 CTD profiler and processed using NOAA's Velocwin V8.85 software and converted to Simrad and CARIS format, then applied directly to the raw Simrad data. The Reson was also equipped with a real time sound velocity probe (Odom DigiBar Pro) at the sonar head and interfaced with the topside unit. Positioning was obtained using Trimble Zephyr 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). NF-07-06 HDCS Multibeam Data 2007 Raw .xtf and raw Simrad (.all format) were converted and processed using CARIS HIPS 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-07-06 HDCS Multibeam Data 2007 After being submitted to CCMA by the contractor, CARIS HIPS 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 Image" was used to export a 8 bit geotif in the coordinate system NAD83 UTM zone 19N.
