This image represents a 1 meter resolution backscatter mosaic of the Virgin Passage in the US Virgin Islands. 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 March 18 2010 to April 06 2010. Data was acquired with a hull-mounted Reson 7125 Kongsberg Simrad EM 1002 multibeam echosounder (400 kHz) 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 from NOAA COOPS. Data is in UTM zone 20 north, datum WGS84. The backscatter component of the bathymetry data was geometrically and radiometrically corrected using Hypack 2010 Geocoder software. Acoustic backscatter mosaics are ostensibly an important piece of information when characterizing surficial seafloor features and delineating benthic habitat.The project was conducted to meet IHO Order 1 and 2 accuracy standards, dependent 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-10-03 during the seventh 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 2010 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.

This ESRI Geotiff 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 Geotiff. Some positional shifts may have occurred between the original data points and the transformed grid.
While the project was conducted to meet IHO Order 1 and 2 accuracy standards, dependent on project area and depth, all users should independently analyze the dataset according to their own needs and standards to determine data usability.

For this project, the Chief Scientist was NOAA/NOS/NCCOS/CCMA's Tim Battista and the Lead Hydrographer was independent contractor Mike Stecher. Data was collected aboard the NOAA ship Nancy Foster from 3/18/10 to 4/06/10, as project number NF-10-03. Multibeam data was acquired in Simrad .hsx and .7k formats with hull-mounted Reson 7125 and Kongsberg Simrad EM 1002 multibeam echosounders (400 kHz). Simrad 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. 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). | Source Produced: NF-10-03 Raw Multibeam Data

Raw SWMB data were converted and processed using CARIS HIPS v7.0 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. | Source Produced: NF-10-03 HDCS Processed Multibeam Data

Acoustic backscatter mosaics are ostensibly an important piece of information when characterizing surficial seafloor features and delineating benthic habitats. The multibeam backscatter data were corrected for geometric and radiometric distortions using Hypack 2010 Geocoder. In particular, the following corrections were applied where appropriate and when artifacts were evident: AVG Trend, TX Power and RX Gain, Area Correction, Spreading, Slant-Range and Extracted Beam Pattern. As no theoretical beam pattern for the Kongsberg Simrad 1002 system exists, it was extracted from a mapped area that was flat and had a relatively uniform (sandy) substrate. Individual lines were also truncated based on ping number and/or angle of incidence where appropriate. The final mosaics were exported as geotiffs, ASCII and XYB files (i.e., X,Y locations in WGS 1984 UTM Zone 20N and Backscatter values as measured in decibels dBs). | Source Produced: 2010_STT_VirginPassage_1m.tif
