MetadataShow full item record
The U.S. Geological Survey, in cooperation with the Texas Water Development Board, began a water-resources investigation of estuaries in September 1967. Data are being collected from most of the principal estuaries along the Texas coast, except Galveston Bay and the Rio Grande. The objectives of the investigation are to determine: (1) the occurrence, source, and distribution of nutrients: (2) current patterns, directions, and rates of movement; (3) physical, organic, and inorganic water quality and its variations; (4) the occurrence, quantity, and dispersion of land drainage entering the estuarine systems; and (5) the chemical and physical characteristics of Gulf water that enters the estuaries. The data from September 1967 - September 1968 is presented.
