Data Type(s): Electro-Magnetic: Gravity, Electro-Magnetic: Magnetics, Location-Elevation: Navigation, Seismics: Air Gun / Water Gun, Seismics: Boomer, Seismics: Multichannel, Seismics: Sub Bottom Profiler

Scientific Purpose/Goals: Cape Hatteras area: High-resolution seismic profiling of the continental shelf, slope and rise for a regional assessment of environmental hazards to petroleum exploration and development. Nature and frequency of slumping, faulting, cut and fill, scour, sand waves, and karst topography were examined. Two lines were run to define a growth fault seen on deep CDP data in area. Offshore Georgia Continental Shelf: Survey conducted to assess possible pipeline corridor routes on the Georgia shelf. High-resolution seismic reflection data were used to assess Pleistocene river channels, scour, sand waves, cut and fill, faulting, shallow gas, and reefs and hardground development. Red Snapper Sink: Detailed high-resolution seismic lines were put across and near the sink to assess the seismic nature of the karst development in the area. Florida Shelf: A high-resolution seismic reflection profile was run between Red Snapper Sink and Cape Canaveral to trace the subsurface expression of the karst surface.
