Equipment Used
Scientific objectives of Investigation of this leg were:
1) to define the details of folding and faulting on the west side of the Bay of 
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.
