This survey is part of an on-going partnership effort funded by the NOAA Coral Reef Conservation Program (CRCP). This survey was funded by a CRCP grant to Andrew David, NOAA Fisheries - Panama City, and Andrew Shepard, NURC/UNCW (The National Oceanographic and Atmospheric Administration's Undersea Research Center at the University of North Carolina at Wilmington). In addition to partners above, other partners include UNCW's Spatial Analysis Lab, US Geological Survey, and the S. Atlantic fishery Management Council.

The primary objective of this joint mapping expedition is to create habitat maps for proposed marine protected areas in the South Altantic Bight (SAB), prior to closure. These bathymetry data will help prepare habitat maps. The surveys will be followed by a ROV expedition later to ground-truth the newly acquired MBES-derived habitat maps. The map will serve as a baseline for assessing change of habitat condition over time, and for monitoring recovery of fish population in the closed area. The new proposed MPAs offer the rare opportunity to quantify habitat and fish assemblages before closure for direct comparision after closure. However, mapping is a prerequisite for any comprehensive research program.
The multi-beam system was mated to a Differential GPS unit, APPLANIX POS/MV
(quantified heave, pitch, roll, and yaw heading).
HYPACK navigation system was used to maintain vessel course throughout the survey.
Sensor data were compiled in SIS Shipboard Data Acquisition and Image Processing
System and initially logged to .all Simrad data files. Files were post-processed
using CARIS HIPS 5.4 software to remove outliers, correct for sound velocity and
tidal stage. HIPS was also used to mosaic backscatter and produce XYA files.
