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 in the US Caribbean from 2/18/04 to 3/5/04, 2/1/05 to 2/12/05, 3/21/06 to 4/2/06, 4/14/07 to 4/27/07, 2/25/08 to 3/8/08, 3/26/09 to 4/2/09, 3/18/10 to 4/6/10. Data was acquired with a pole-mounted Reson 8101 ER multibeam echosounder (240 kHz) in 2004 and 2005, a hull-mounted Kongsberg Simrad EM 1002 multibeam echosounder (95 kHz) in 2006, 2007, 2008, 2009 and 2010, a moon pool flange-mounted Reson 8124 multibeam echosounder (200 kHz) for water depths of less than 75 meters in 2007, and a moon pool flange-mounted Reson 7125 multibeam echosounder (dual frequecy, 200/400 kHz) for water depths of less than 75 meters in 2009 and 2010. 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 19 north, datum NAD83. The processed CARIS data was used to generate a CARIS BASE surface based on swath angle from 2004-2009, and based on CUBE in 2010. 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 GeoTIFF. In 2010, the BASE surface was exported as a BAG file, and converted to a GeoTIFF in ESRI ArcMap 10. Rugosity was derived from this surface using NOAA's Benthic Terrain Modeler extension. 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) projects NF-04-06, NF-05-05, NF-06-03, NF-07-06, NF-08-04, NF-09-01, and NF-10-03 during the first seven 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 2004-2010 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 ESRI Grid 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.

NF-10-03 BAG Multibeam Data 2010 An ESRI grid of source bathymetry was input into the Rugosity Builder Tool, a component of the ArcGIS Benthic Terrain Modeller (BTM). The BTM tool, a collection of ArcGIS terrain visualization tools developed by the Oregon State University (OSU) Department of Geosciences and the National Oceanic and Atmospheric Administration (NOAA) Coastal Services Center, calculated the rugosity of that bathymetric grid based on an algorithm developed by Jeff Jenness. A short summary of the process, quoted directly from the BTM's documentation, is as follows: "...rugosity derivation relies, in part, on a neighborhood analysis using a 3 grid cell by 3 grid cell neighborhood. An algorithm is passed through the Raster Map Algebra Operation object within Spatial Analyst that calculates the planar distance between the center point of the center cell and of each of the eight surrounding cells in the neighborhood. Next, using the Pythagorean Theorem, the surface distance is calculated for each planar distance using the difference in elevation between the cells. The result of this function is sixteen separate grid data sets with each cell value equal to this surface distance. The next step in the process is to calculate the area formed by three adjacent sides. The result is eight triangular surface area grids. These grid datasets are combined to obtain a surface area data set for the input bathymetric data set. The final step in the process is to create a data set that represents the ratio of surface area to planar area. This final data set represents rugosity for the study area." More information on the specific algorithms used, and contact points for questions, can be found in the BTM's documentation. Rugosity values near 1 represent flat smooth terrain, while higher values reflect increasing rugosity or terrain roughness. For rugosity grid interpretation, is recommended that the grid be reclassified according to standard deviation divisions.
