NOAA TIFF Image - 10m Bathymetric Rugosity, South Atlantic Bight - Deep Coral Priority Areas - NOAA Ron Brown - (2010), UTM 17N NAD83
Description
This dataset contains a unified GeoTiff with 10x10 meter cell size representing the rugosity of several deep coral priority areas off the South Atlantic Bight, derived from data collected in November 2010. NOAA's NOS/NCCOS/CCMA Biogeography Branch, in collaboration with NOAA vessel Nancy Foster, as well as federal, university, and private sector partners, acquired multibeam bathymetry data off the South Atlantic Bight from 11/13/2010 to 11/22/2010. Data was acquired with a hull-mounted Kongsberg Simrad EM 1002 multibeam echosounder (95 kHz). It was processed by a NOAA contractor using CARIS HIPS software. Attitude and sound velocity correctors applied to the data. Verified tides were not applied to the data, leaving the depth values referenced to the ellipsoid. The imagery is projected in the UTM Zone 17 north, NAD83 datum. The processed CARIS data was used to generate a CARIS BASE surface based on swath angle. The CARIS Export option "BASE Surface to Image" was then used to create a GeoTiff of the priority areas. Rugosity was derived from this surface using NOAA's Benthic Terrain Modeler extension.
