Field Activity Details for field activity 1980-035-FA

Other ID: NE-80-3

Status: Completed

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

Funding Program(s):

Principal Investigator(s): George B. Tirey

Affiliate Investigator(s):

Information Specialist(s):

Data Type(s): Location-Elevation: Navigation, Seismics: Air Gun / Water Gun, Seismics: Multichannel

Scientific Purpose/Goals: Utilize common-depth-point (CDP), digital, and multichannel techniques to locate and map a monoclinal flexure of the Cap au Gres Fault, and demonstrate that the marine seismic system could be used for making relatively deep penetration seismic reflection surveys on shallow (less than 10 m in depth) inland waterways that have organic sediment floors.


Start Port/Location: Venetian Harbor Marina, Portage des Sioux, MO

End Port/Location: Venetian Harbor Marina, Portage des Sioux, MO

Start Date: 1980-12-12

End Date: 1980-12-16

Equipment Used: Air gun, Multichannel seismics, Northstar 6000 LORAN-C

Information to be Derived:

Summary of Activity and Data Gathered: The survey was carried out between the mouth of the Missouri River and the power plant at Portage des Sioux. There were not any faults observed on any of the monitor records made during this survey. Penetration on the monitor records was in general limited to approximately 100 to 150 ms of two-way travel time. Strong side reflections from the river banks up to 1.0 s of two-way travel time were recorded on the monitor record. As of this writing, the multichannel digital data recorded on the magnetic tapes have not been processed.
