Area of Operations: Chandeleur Sound, Chandeleur Islands, Mississippi Sound, Louisiana-Mississippi-Alabama continental shelf, United States, Gulf of Mexico, North America, North Atlantic

Dates: June 29, 1981 to July 24, 1981

Chief scientist: Ron Miller

Objectives: Preliminary report detailing findings of 3 phases - first two phases recorded in cruise reports 81007 and 81008. Objective of phase 3 onboard CARANCAHUA was the completion of trackline runs laid out in phase 1, run in phase 2, and continued in shallow waters in phase 3. Purpose of study was to provide an interpretation of the geologic framework and geologic history of the Louisiana-Mississippi OCS area since the middle Pleistocene, and to present the regional distribution of geologic features that can be hazardous to offshore gas and oil production.

Type of Activity: Seismic profiling;

Information to be derived: Sea floor map; Bathymetric maps;

Summary: 700 km of seismic data and 75 grab samples collected in phase 3 cruise.
