This is the eighth in a series of annual basic-data reports that have been prepared by the U.S. Geological Survey since 1970 presenting results of systematic measurments in principal estuaries along the Texas coast. Approximately 170 designated data collection sites were visited during the 1976 water year. The report contains field measurments of dissolved oxygen, specific conductance, temperature, pH, transparency, and turbidity at several points along a vertical at each site. Also listed are the results of laboratory analyses of samples from selected sites, including the principal inorganic ions, biochemical oxygen demand, phenols, organic carbon, insecticides and herbicides, ammonium, nitrate, nitrite, phosphate, and other selected ions such as metals. Water and sediment sampling is represented. Objectives of the continuing investigation are to define: the occurence, source, and distribution of nutrients.
