Popis

This image represents a 4 meter resolution slope surface of the bathymetry of a reef shelf/bank and the steep canyons and slopes of the NE Reserve, offshore of Fajardo, Puerto Rico. The M-I907-NF-12 survey was split into two sites: W00221 in the west and W00222 in the east. 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 Grand Reserve from 4/08/2012 to 4/20/2012. Data was acquired with a hull-mounted Reson 7125 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 Hypack 2012 acquisition software. Slope was derived from this surface using the slope calculator, a function of ESRI's Spatial Analyst extension.
