Summary for Field Activity Number 1976-045-FA

Alternate Leg ID: IDA GREEN 22; CORPUS 40/46

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

Dates: October 29, 1976 to November 03, 1976

Objectives: Obtain quasi-synoptic information on suspended sediment transport within the South Texas outer continental shelf. Obtain samples of the water column for sediment texture and concentration, water chemistry and coccoliths to establish seasonal variability pattterns. Obtain vertical transmittance-temperature profiles to establish seasonal turbidity patterns. Cast drift bottles to measure surface currents during the cruise period.

Type of Activity: Sampling

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

Summary: This cruise was the fourth of six cruises to evaluate seasonal variability of suspended sediment transport patterns within the South Texas OCS. The remaining two cruises are scheduled for March and May 1977. Stations: 26; Water samples: 78 (3 samples at each station); Vertical transmittance-temperature profiles: 26; Drift bottles: 312.
