Abstract:
This dataset contains an ESRI Grid representing the slope (in degrees) of the bathymetry of the north shore of St. Croix, US Virgin Islands, based on a 3 m bathymetric grid.

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 3/21/06 to 4/2/06. Data was acquired with a hull-mounted Kongsberg Simrad EM 1002 multibeam echosounder (95 kHz) and processed by a NOAA contractor using CARIS HIPS v6.0 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. An ASCII XYZ file was exported from the BASE surface and opened in ESRI ArcMap 9.1 as an XY event. Then the ArcToolbox conversion tool 'Feature to Raster' was used to generate an ESRI Grid of bathymetry. Finally, the Slope calculator within ArcGIS Spatial Analyst/Surface Analysis was used to calculate slope in degrees, using that ESRI Grid of source bathymetry.

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.

Purpose:
This derived bathymetry product is based on multibeam data that was collected as IOCM (Integrated Ocean and Coastal Mapping) project NF-06-03 during the third year of an ongoing NOAA scientific research mission in the US Caribbean to characterize midshelf and 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 2006 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 USVI seafloor.
Supplemental_Information:
Depth datum is mean lower low water, units are meters and encoding method is explicit depth coordinate included with horizontal coordinates. Vertical Coordinate System information may be found in the Data Acquisition and Processing Report (DAPR) for cruise number NF-06-03 at <http://ccma.nos.noaa.gov/products/biogeography/usvi_nps/pdf/NF-06-03%20DAPR.pdf>

Logical_Consistency_Report:
While the project was conducted to meet IHO Order 1 and 2 accuracy standards, dependant on project area and depth, all users should independently analyze the dataset according to their own needs and standards to determine data usability.
Completeness_Report:
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.

Process_Step:
Process_Description:
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 3/21/06 to 4/2/06, as project number NF-06-03. Multibeam data was acquired with a hull-mounted Kongsberg Simrad EM 1002 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 60 degrees from nadir, 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) primary tide stations at Charlotte Amalie, VI (9751639) and Lime Tree Bay, VI (9751401).

Process_Step:
Process_Description:
Raw SWMB data in Simrad .all format were converted and processed using CARIS HIPS 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: 2006
Process_Step:
Process_Description:
After being submitted to CCMA by the contractor, CARIS HIPS v6.0 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).
Source_Used_Citation_Abbreviation: NF-06-03 BASE Surface
Process_Date: 2006
Process_Step:
Process_Description:
The ASCII XYZ file was opened in ArcMap 9.1 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 9.1 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.

Process_Description:
An ESRI grid of source bathymetry was input into the Slope calculator tool, a component of the ArcGIS Spatial Analyst extension. The output grid of calculated slope, with units in degrees, was created with vertical exaggeration z equals 1 and with the same grid resolution as the source bathymetry grid.
