Area of Operations: south Texas outer continental shelf, Texas, Gulf of Mexico, United States, North America, North Atlantic
Dates: May 28, 1977 to June 05, 1977
Chief scientist: Chuck Holmes
Objectives: Obtain fresh large-volume cores to aid in the contracted study into the origin of the 27 degree geochemical anomaly, a region on the shelf where an increase in copper, nickel and manganese is apparent.
Type of Activity: Sampling; Seismic profiling;
Information to be derived: Samples and chemical analysis; Morphology;
Summary: Although the prime mission of the cruise was to obtain cores for geochemical study, attainment of high-resolution profiles was considered important for proper sedimentologic interpretation of the cores. Cores were taken over the entire shelf with sites selected on the basis of previous work. In addition, 20 cores were concentrated around the 27 degree latitude. Hydroplastic cores: 50; Minisparker: 500 km; 7/3.5 kHz Sub-bottom profiler: 600 km.
