Abstract:

This image represents a 1 meter resolution backscatter mosaic of the bathymetry of a reef shelf/bank south of Vieques, Puerto Rico. 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 and around the Northeast Reserve from 3/05/2013 to 3/29/2013. Data was acquired with a moon pool mounted Reson 7125 multibeam echosounder (400 kHz). Data is in UTM zone 20 north, datum NAD83. The backscatter component of the bathymetry data were geometrically and radiometrically corrected using .HSX and .7k file pairs that were converted to GSF in Hypack 2012, then processed in Fledermaus Geocoder Toolbox 7.3.3c. Acoustic backscatter mosaics are 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-13-2 USVI during the tenth 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 2013 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 US Caribbean seafloor.

Data Quality

Horizontal Positional Accuracy:

See Data Acquisition and Processing Report (DAPR) for NF-13-2 USVI

Vertical Positional Accuracy:

See Data Acquisition and Processing Report (DAPR) for NF-13-2 USVI.

Completeness Report:

This Backscatter GeoTIFF is sourced from a Fledermaus gridded dataset. The original full-resolution multibeam data 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, dependent 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: 600224
Description:

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 03/05/2013 to 3/29/2013, as project number NF-13-2 USVI. Multibeam data was acquired from Simrad EM1002 in .all format and from Reson Seabat 7125 in .hsx and .7k format. Backscatter collection was enabled for both systems. 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). | Source Produced: Raw Multibeam Data

Process Step 2

CC ID: 600225
Description:

Raw .hsx and .all data were converted to GSF format using Hypack. The multibeam backscatter data were corrected for geometric and radiometric distortions using Fledermaus Geocoder Toolbox 7.3.3. In particular, the following corrections were applied: TVG correction, AVG Trend, TX Power and RX Gain, Area Correction, Spreading and Slant-Range. Individual lines were also truncated based on ping number and/or angle of incidence where appropriate. | Source Produced: NF-13-2 USVI 1m Backscatter Mosaic

The final corrected backscatter (decibel) mosaics were exported as 32 bit GeoTIFFs using coordinate system NAD 1983 UTM Zone 20N. | Source Produced: NF13_ PR_Vieques _400khz_BS_1m.tif
