Data Type(s): Electro-Magnetic: Gravity, Electro-Magnetic: Magnetics, Location-Elevation: Navigation, Seismics: Air Gun / Water Gun, Seismics: Sparker, Seismics: Sub Bottom Profiler, Sonar: Single Beam

Scientific Purpose/Goals: 1. Determine location, extent, morphology, and internal geometry of mass sediment movement (slumps, slides) on the continental slope off New England using high-resolution geophysical methods (14.5 days). 2. Study and correlate stratigraphy of Jurassic and Cretaceous strata north and south of the New England sea mount chain using geophysical methods (3 days).

Vehicle(s):

Start Date: 1979-06-07

Start Port/Location: Provincetown, MA

End Date: 1979-06-25

End Port/Location: Woods Hole, MA

Equipment Used: Air gun, Teledyne single-channel 300-500J 40-tip minisparker, 3.5 kHz, Marine magnetometer, Gravity meter (wh), Integrated Navigation System, Single channel hydrophone, 12 kHz

Information to be Derived: Morphology;

Summary of Activity and Data Gathered: Overall data quality is excellent, with good resolution and penetration. The data show much slumping on the continental slope between 500 and 2000 m water depth. Many displaced slump bodies occur near the base of the continental slope and on the upper continental rise. Slump study - 3.5 kHz/Minisparker/40 cu. in. airgun: 3257 km; Deep Stratigraphy - 3.5 kHz/Minisparker/500,160 cu. in. airguns: 775 km; Gravity: 4032 km; Magnetics: 4032 km.
