Summary for Field Activity Number 1983-008-FA

Alternate Leg ID: GY-83-12

Area of Operations: Carolina Trough, offshore Florida, southern Blake Plateau, United States, North America, North Atlantic

Dates: September 22, 1983 to October 06, 1983

Objectives: 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.

Type of Activity: OBS work
Seismic profiling
Sampling

Information to be derived: Time series data
Morphology
Ocean Bottom seismometer
Reflection/refraction

Summary: 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.

USGS Project Number: 9470-01831 9470-01796 etc.
