Field Activity Details for field activity 1971-001-FA

Other ID: UGEO Leg 1; CORPUS 15/16

Status: Completed

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

Funding Program(s):

Principal Investigator(s): George W. Moore

Affiliate Investigator(s):

Information Specialist(s):

Data Type(s): Electro-Magnetic: Gravity, Electro-Magnetic: Magnetics, Location-Elevation: Navigation, Seismics: Sparker, Seismics: Sub Bottom Profiler

Scientific Purpose/Goals: Scientific objectives of this cruise leg were: (1) to define the details of folding and faulting on the west side of the Bay of Campeche; (2) to study the extension into the bay of the Mexican volcanic belt and related volcanic lineaments; (3) to investigate the origin of a belt of salt domes that extends along the floor of the east side of the basin; and (4) to acquire new evidence that might bear on the origin of the Gulf of Mexico.

Vehicle(s):

Start Date: 1971-05-27

Start Port/Location: Corpus Christi, TX

End Date: 1971-06-17

End Port/Location: Veracruz, Mexico

Equipment Used: Sparker system, 3.5 kHz, ITT 4007 satellite navigation, Decca radar system, Magnetometer (wh), Gravity meter (wh), Single channel hydrophone

Information to be Derived: Grain size analysis; Morphology;

Summary of Activity and Data Gathered: A total of 19 days were spent at sea in the Gulf of Mexico during Leg 1 which began at Corpus Christi on May 27, 1971, and ended at Veracruz. A 1-day run out of Veracruz at the start of Leg 2 has been made a part of the data of Leg 1. The sub-bottom acoustic profiles obtained between Corpus Christi and Veracruz and within the project area at the southwest of the Bay of Campeche near Veracruz were run at an average ship speed of 8.3 knots. 220 kJ Sparker data: 7000 km; 3.5 kHz EDO data: 7000 km.
