The southwestern extent is near Tennessee Reef and the northeastern extent is offshore of the Fort Lauderdale area. The seabed elevation (bathymetry) and acoustic imagery data (backscatter) were collected using multibeam echosounders (MBES) on NOAA vessels including the NOAA Survey S3009 and the R/V Dodson (F2713).
