Other ID: IDA GREEN 22; CORPUS 40/46

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 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.


Start Port/Location: Corpus Christi, TX

End Port/Location: Corpus Christi, TX

Start Date: 1976-10-29

End Date: 1976-11-03

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

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

Summary of Activity and Data Gathered: 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.
