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 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 unified ESRI Grid with 10 meter cell size representing the slope (degrees) of selected portions of seafloor around La Parguera, Abrir La Sierra Bank, Bajo De Cico, and Isla De Mona in Puerto Rico and St. Croix, St. Thomas, and St. John in the US Virgin Islands, derived from data collected in 2004, 2005 2006, and 2007. 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 and 2/1/05 to 2/12/05, including La Parguera, P.R. from 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. In Abrir La Sierra, Bajo de Cico, and Isla de Mona, P.R., the team, also in collaboration with NOAA vessel Nancy Foster and territory, federal, and private sector partners, acquired data from 4/14/07 to 4/24/07. Data with acquired with a hull-mounted Kongsberg Simrad EM 1002 (95 kHz) multibeam echosounder, as well as with a Reson 8124 (200 kHz) multibeam echosounder for shallow areas of Abrir La Sierra Bank. Data 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 19 north, datum NAD83. The processed CARIS data was used to generate a CARIS BASE surface based on swath angle. For USVI and La Parguera, P.R. (2004-2006), an ASCII XYZ file was exported from the BASE surface and opened in ESRI ArcMap 9.x as an XY event. Then the ArcToolbox conversion tool 'Feature to Raster' was used to generate the final ESRI Grid. For Abrir La Sierra Bank, Bajo de Cico, and Isla de Mona (2007), an ASCII XYZ file was exported from the BASE surface and opened in ESRI ArcMap 9.x using the XYZ to raster tool. 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, NF-06-03, and NF-07-06 during the first, second, third and fourth 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, 2006, and 2007 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 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) for NF-04-06/NF-05-05/NF-06-03/NF-07-06.

For this project, the Chief Scientist was NOAA/NOS/NCCOS/CCMA's Tim Battista and the Lead Hydrographer for 2004-2006 was independent contractor Jay Lazar. For 2007 the Lead Hydrographer was independent contractor Mike L. Stecher. 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 and 4/14/2007 to 4/24/2007. 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). 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 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-04-06/NF-05-05/NF-06-03/NF-07-06 HDCS Multibeam Data 2007 Raw GSF, XTF, and Simrad data (.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-04-06/NF-05-05/NF-06-03/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 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-04-06/NF-05-05/NF-06-03/NF-07-06 BASE Surface 2007 The ASCII XYZ file was opened in ArcMap 9.x 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.x 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. NF-04-06/NF-05-05/NF-06-03/NF-07-06 ASCII XYZ Multibeam Data 2007 2007 data for Abrir La Sierra, Bajo de Cico, and Isla De Mona, P.R. was merged with previous 2004-2006 data for La Parguera P.R., and St. John, St. Croix, St. Thomas, USVI (reprojected to UTM zone 19 N) using the MERGE command in the Spatial Analyst raster calculator.
