NOAA TIFF Image - SouthWest Shelf, St. Croix, USVI - Benthic Habitat Characterization - NOAA Ship Nancy Foster - M-1907-NF-14 (2014), UTM 20N NAD83

This image represents a 1 meter resolution bathymetry of the reef shelf and the steep slopes of the Southwest Shelf (H12640) of St. Croix, US Virgin Islands. The M-I907-NF-14 survey was a continuation of the NOAA Biogeography Branch's Seafloor Mapping of the US Caribbean project. 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 St. Croix between March 12th and April 2, 2014. 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 bathymetry data were geometrically and radiometrically corrected using Hypack 2014 acquisition 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.
