Information Specialist(s):
Data Type(s): Seismics: Air Gun / Water Gun, Electro-Magnetic: Gravity, Electro-Magnetic: Magnetics, Location-Elevation: Navigation, Seismics: Multichannel, Seismics: Sub Bottom Profiler, Sonar: Single Beam
Scientific Purpose/Goals: Obtain a near-shore high-resolution seismic reflection profile in order to both correlate reflections with onshore wells and aid in the interperetation of data obtained in 1979 and 1980 north and south of Cape Hatteras. Obtain a seismic and magnetic profile over the strong circular magnetic anomaly off Norfolk, VA.
