Other ID: W-39, Leg 4
Status: Completed
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Funding Program(s):
Principal Investigator(s): Charles E. McClennen
Affiliate Investigator(s): Arthur G. Gaines, Jr. - SEA
Information Specialist(s):
Data Type(s): Sonar: Sidescan, Seismics: Sub Bottom Profiler, Location-Elevation: Navigation
Scientific Purpose/Goals: USGS cruise (4 days) piggybacked on SEA cruise to conduct sidescan sonar and high-resolution seismic reflection surveys of a west-east transect across the South Carolina shelf off Charleston and a more extensive survey of the Mud Patch on the southern New England shelf.
Vehicle(s):
Start Port/Location: Charleston, SC
End Port/Location: Woods Hole, MA
Start Date: 1978-05-14
End Date: 1978-05-24
Equipment Used: ORE sidescan, Raytheon RTT 1000 Seismic System, Loran-A, Loran-C
Information to be Derived: Sea floor map; Morphology;
Summary of Activity and Data Gathered: No clear sub-bottom reflectors were noted in the entire survey of the southern New England shelf. In part this reflects limitations of the profiling equipment although better records might have been obtained at slower speeds with greater submergence of the transducer. Sidescan sonar: 368 km; Sub-bottom profiles: 368 km.
