Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Principal Investigator(s): David Twichell
Affiliate Investigator(s): Hans Nelson - PMG
Data Type(s): Biological Field Study: Experiments, Imagery: Photo, Imagery: Video, Location-Elevation: Navigation, Sampling: Geology, Seismics: Air Gun / Water Gun, Seismics: Boomer, Seismics: Bubble Gun, Seismics: Sparker, Seismics: Sub Bottom Profiler, Sonar: Sidescan, Sonar: Single Beam
Scientific Purpose/Goals: A turbidity current pathway on the Louisiana slope was to be mapped with SIS-7000, seismic profiles, and piston cores to understand sand deposit formation. The study area was between 26 and 27.5 deg. N and 91 and 92 deg. W in water depths ranging from 800-2,800 m.
