This image represents a 0.5 meter resolution backscatter mosaic of the south shore of St. Thomas, US Virgin Islands.
NOAA's NOS/NCCOS/CCMA Biogeography Team and NOAA/NOS/OCS/HSD personnel, 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. Data was acquired with a pole-mounted Reson 8101 ER multibeam echosounder (240 kHz) and processed by a NOAA contractor using CARIS HIPS v5.4 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. Within CARIS, each line of backscatter data was evaluated for bottom tracking and was slant-range corrected. Data was not corrected for gain or transmit power artifacts. Backscatter mosaics were then created using the CARIS shine-through option. Finally, a georeferenced imagery file was exported from the mosaic.
While the project was conducted to meet IHO Order 2 accuracy standards, there is a roll artifact (averaging 0.5m high) in the dataset that the user should take into consideration when performing any analysis.
This multibeam data product was collected as project NF-04-06 during year one of a two-year NOAA scientific research mission in the US Virgin Islands to characterize nearshore coral reef habitats. 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 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.
Depth datum is Mean lower low water, units are meters and encoding method is explicit depth coordinate included with horizontal coordinates

While the project was conducted to meet IHO Order 2 accuracy standards, there is a serious roll artifact (averaging 0.5m high) in the dataset that the user should take into consideration when performing any analysis. This artifact is likely the result of small errors is the measurement of sensor offsets, combined with strumming motion from the pole on which the sonar was mounted.

For this project, the Chief Scientist was NOAA/NOS/NCCOS/CCMA's Dr. Mark Monaco and the Lead Hydrographer was NOAA/NOS/OCS/HSD/PHB's Physical Scientist Sean Rooney. Data was collected aboard the NOAA ship Nancy Foster from 2/18/04 to 3/5/04, as project number NF-04-06-VI. Multibeam data was acquired in XTF format with a pole-mounted Reson 8101 ER multibeam echosounder (240 kHz), with options 033 and 040. Triton-Elics ISIS 6.20 software was used to interface with the Reson system. Line spacing for acquisition was typically three times the water depth, giving 100% bottom coverage, and data was retained out to 70 degrees from nadir. Heave, roll, pitch and heading correctors were collected using an Ixsea Octans gyrocompass and integrated motion sensor. Sound velocity profiles were acquired with a Seabird Electronics SeaCat SBE19 CTD profiler and processed using Velociwin 8.40 (NOS HSTP product), then concatenated. Positioning was obtained using a Trimble DSM212L GPS receiver with differential correctors from U.S. Coast Guard beacon Isabel, PR. 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).
NF-04-06 XTF Multibeam Data
200403
SWMB data in XTF format were converted and processed using CARIS HIPS v5.3 and 5.4 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 HDCS Multibeam Data
200408
The contractor used CARIS HIPS v5.4 to evaluate each line for bottom tracking and to perform slant-range corrections. Data was not corrected for gain or transmit power artifacts. After this cursory processing, the data was mosaiced together using the shine-through backscatter option. The resulting backscatter mosaic was then exported as an image file.
