Coastal & Marine Geology Program

Field Activity Details for field activity 1979-022-FA

Other ID: none

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s):

Principal Investigator(s): Mahlon M. Ball

Affiliate Investigator(s):

Information Specialist(s):

Data Type(s): Seismics: Multichannel, Location-Elevation: Navigation

Scientific Purpose/Goals: Collect state-of-the-art multifold seismic reflection data across the West Florida Margin and on the Destin Dome for structural and stratigraphic framework studies and resources assessment of the northern MAFLA OCS.


Start Date: 1979-08-06

Start Port/Location:

End Date: 1979-08-21

End Port/Location:

Equipment Used: Multichannel seismics, Northstar 6000 LORAN-C, Magnavox System 5000 integrated navigation system

Information to be Derived: Morphology;

Summary of Activity and Data Gathered: Data quality is assumed excellent on the basis of near-trace monitor records, galvo-camera records, and observations of reflection returns and noise as displayed on the streamer monitor. Major problems causing delays and breaks-in-line involved mainly mechanical malfunctions such as compressor breakdowns, airgun malfunctions, problems with ship generators, traffic, and acceptable satellite passes. 64-channel (32-fold) CDP seismic reflection data: 17 lines (MAFLA Gulf Mex 1-17), 1284.6 km; 12 kHz fathometer data: 1284.6 km.
