Scientific Purpose/Goals: Collect airgun ocean-bottom seismometer (OBIP) refraction and multichannel reflection data along lines to be used for long range explosive refraction profiles next spring, in an effort to determine the structure of the crust beneath the Carolina Trough and in the transition zone from the marginal basin to oceanic crust.
Vehicle(s):
Start Port/Location: Woods Hole, MA

Start Date: 1983-09-22
End Date: 1983-10-06
Equipment Used: Multichannel seismics, Air gun, 3.5 kHz, Gravity corer, Integrated Navigation System, Ocean Bottom Seismometer
Information to be Derived:
Summary of Activity and Data Gathered: 400 km single-channel digital seismic reflection; 210 km multichannel reflection and OBIP refraction; 700 km 3.5-kHz echo sounding; 1 mooring deployed and recovered (#272, current meter). Total for continuous data field is sum of all data gathered.
