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 Northeast Reserve from 4/04/2012 to 4/20/2012. Data was acquired with a hull-mounted Reson 7125 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 NAD83. The backscatter component of the bathymetry data were geometrically and radiometrically corrected using .HSX and .7k file pairs in Fledermaus Geocoder Toolbox7.3.3. 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 M-I907-NF-12 during the ninth 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 2012 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.

Completeness_Report: This Backscatter GeoTIFF is sourced from a CARIS 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 Mike Stecher. Data was collected aboard the NOAA ship Nancy Foster from 4/04/2012 to 4/20/2012, as project number M-I907-NF-12. Multibeam data was acquired in Simrad .hsx and .7k formats with hull-mounted Reson 7125 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). Source_Used_Citation_Abbreviation: Raw Multibeam Data M-I907-NF-12 Process_Date: 201204 Process_Step: Process_Description: Raw .hsx and .all 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_Used_Citation_Abbreviation: M-I907-NF-12 HDCS Processed Multibeam Data Process_Date: 201210 Process_Step: Process_Description: 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 Fledermaus Geocoder Toolbox 7.3. 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 Reson 7125 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 in NAD 1983 UTM Zone 20N and Backscatter values as relative decibel outputs in 16 bit 0-255 colorscale.
