Summary Information for Field Activity 1977-011-FA

Area of Operations: south Texas outer continental shelf, Matagorda Bay, Texas, Gulf of Mexico, United States, North America, North Atlantic

Dates: March 17, 1977 to March 21, 1977

Chief scientist: Gerry Shideler

Objectives: Obtain quasi-synoptic information on the suspended-sediment transport system within the South Texas OCS. Specific objectives were: to obtain samples of the water column for analyses of sediment texture and concentrations, sediment mineralogy and trace metals, water chemistry, and coccoliths to establish temporal variability patterns; to obtain vertical transmittance-temperature profiles to establish regional turbidity patterns; and to cast drift bottles to measure surface currents during the cruise period.

Type of Activity: Suspended-sediment transport system;Suspended-sediment transport system

Information to be derived: Time series data; Samples and chemical analysis; Suspended sediment concentrations;

Summary: This cruise was the fifth of six scheduled cruises designed to evaluate the temporal variability of suspended-sediment transport patterns within the South Texas OCS region. The remaining cruise is scheduled for May 1977. Vertical transmittance-temperature profiles: 26; Water column samples (surface, mid, bottom): 78 samples at 26 stations; Drift bottles: 312 casts.
