Data Type(s): Location-Elevation: Navigation, Sampling: Biology, Sampling: Geology, Seismics: Air Gun / Water Gun, Seismics: Sparker

Scientific Purpose/Goals: Collect high-resolution seismics and cores for geologic interpretation of sedimentologic processes in a deep-water fan environment.


Start Port/Location: Venice, LA

End Port/Location: Gulfport, MS

Start Date: 1981-05-09

End Date: 1981-05-15

Equipment Used: Corer - slow, Air gun, Sparker , Single channel hydrophone, Box corer, Magnavox satellite positioning system, Loran-C, Gyro compass

Information to be Derived:

Summary of Activity and Data Gathered: Using several seismic devices, 1070 km of high-resolution seismics and bathymetry were collected over the Mississippi Fan. In addition, four piston cores, four box cores and a grab sample were collected. Navigation was from the integrated system aboard the R/V GYRE. High-resolution seismics (3.5 kHz)/bathymetry (12 kHz): 1070 km; Piston cores: 4; Box cores: 4; Grab sample: 1.
