NOAA TIFF Image - 3x3m Multibeam Backscatter, US Virgin Islands - Vieques Island (South Bank) - Project NF-09-01 - (2009), UTM 20N NAD83 (NCEI Accession 0131857)
This dataset contains a GeoTIFF with 3x3 meter cell size representing the backscatter or intensity of sound returned from the seafloor on the bank/shelf escarpment south of Vieques Island, Puerto Rico. This intensity surface was collected in March and April 2009 using an EM 1002 multibeam echosounder. Acoustic backscatter mosaics are an important piece of information when characterizing surficial seafloor features and delineating benthic habitats. NOAA's NOS/NCCOS/CCMA Biogeography Branch, in collaboration with NOAA vessel Nancy Foster and territory, federal, and private sector partners, acquired multibeam data around Vieques Island from 3/26/09 to 4/2/09. Data was acquired with a hull-mounted Kongsberg Simrad EM 1002 multibeam echosounder (95 kHz) for water depths greater than 75 meters, and with a moon pool flange-mounted Reson 7125 multibeam echosounder (dual frequecy, 200/400 kHz) for water depths of less than 75 meters. The backscatter component of the multibeam data were geometrically and radiometrically corrected using Fledermaus Geocoder Toolbox (FMGT) software. 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.
