Other ID: Decca Profiler 1; CORPUS 46

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s):

Principal Investigator(s): Gerald L. Shideler

Information Specialist(s):

Data Type(s): Environmental Data: Temperature, Environmental Data: Turbidity, Location-Elevation: Navigation

Scientific Purpose/Goals: 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.


Start Port/Location: Corpus Christi, TX

End Port/Location: Corpus Christi, TX

Start Date: 1977-03-17

End Date: 1977-03-21

Equipment Used: Martek Transmissometer, Raytheon radar, Loran-A

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

Summary of Activity and Data Gathered: 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.
