| Purpose | Leg 1, September 18-25, 1980, Mid-range sidescan sonar: Survey with the Lamont mid-range sidescan sonar system in the lease block areas of Sale 56 in order to determine environmental conditions or hazards prior to leasing of these blocks for petroleum development. Test the utility of the mid-range sidescan sonar system in mapping of the shelf-edge reef system. Examine areas of bedding terminations on the shelf and slope south of Cape Hatteras believed to be slump scars. Determine the utility of the sidescan-sonar system in mapping salt diapirs. Legs 2 and 3, September 26 - October 14, 1980, High-resolution seismic reflection: Regionally access the types and frequencies of environmental hazards or constraints to petroleum exploration or development in the area from Cape Hatteras to the Virginia state line. Survey the shelf, slope and rise on a 25 km grid as part of a regional shallow stratigraphic study. Tie the drill holes ASP-7, ASP-8, AMCOR 6006, and ASP-5 with one continuous line as an aid in regional stratigraphic studies. Study the offshore extent and nature of the Florida aquifer and possible structure or leaks (exposures) affecting the aquifer. | ||||||||

| Summary | Leg 1, September 18-25, 1980: 335 km sidescan sonar, 3.5 kHz, and minisparker data collected. Legs 2-3, September 26 - October 14, 1980: 2,950 km airgun and 3.5 kHz data collected. | ||||||||
