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.
