Abstract:

This image represents a 1 meter resolution backscatter mosaic of an offshore portion of the NPS's Virgin Islands Coral Reef National Monument, south of St. John, US Virgin Islands. 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 Virgin Islands from 2/1/05 to 2/12/05. 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. The backscatter component of the bathymetry data were geometrically and radiometrically corrected using Geocoder 3.2.1 software. Acoustic backscatter mosaics are ostensibly an important piece of information when characterizing surficial seafloor features and delineating benthic habitats. 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 multibeam data was collected as IOCM (Integrated Ocean and Coastal Mapping) project NF-05-05 during the second 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 300 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 2005 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.

Data Quality

Horizontal Positional Accuracy:

See Data Acquisition and Processing Report (DAPR) for NF-05-05.

Vertical Positional Accuracy:

See Data Acquisition and Processing Report (DAPR) for NF-05-05.

Completeness Report:

This Backscatter GeoTIFF is sourced from the original full-resolution multibeam data that was used to create a down sampled uniform-resolution backscatter grid. The down sampled grid nodes from that backscatter surface were then exported and used to generate the ESRI GeoTIFF. Some minor positional shifts may have occurred between the original data points and the transformed GeoTIFF.

Conceptual Consistency:

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.

Process Steps

Process Step 1

CC ID: 599615
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 2/1/05 to 2/12/05, as project number NF-05-05-VI. Multibeam data was acquired in GSF format with a pole-mounted Reson 8101 ER multibeam echosounder (240 kHz), with options 033, 037, and 040. Reson backscatter snippet collection was enabled. SAIC ISS 2000 software was used to interface with the Reson system. Line spacing for acquisition was three times the water depth, and data was retained out to 60 or 70 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 GSF 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). | Source Produced: NF-05-05 Raw Multibeam Data

Process Step 2

CC ID: 599616
Description:

Raw SWMB data in GSF (generic sensor format) format were converted and processed using CARIS HIPS v5.4 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. | Source Produced: NF-05-05 HDCS Processed Multibeam Data

Process Date/Time: 2008-07-01 00:00:00
Source: NF-05-05 Raw Multibeam Data

Process Step 3

CC ID: 599617
Description:

The multibeam backscatter data were corrected for geometric and radiometric distortions using Geocoder 3.2.1 In particular, the following corrections were applied where appropriate and when artifacts were evident: AVG Flat, TX Power and RX Gain, Area Correction, Spreading and RX Beam Pattern. Individual lines were also truncated based on ping number where appropriate. The final mosaics were exported as ASCII files (i.e., X,Y locations in WGS 1984 UTM Zone 20N and Backscatter values as measured in decibels dBs). | Source Produced: Backscatter_NPSOffshore_1m_2005.tif
