Abstract

Suspended-solids concentration data were collected in San Francisco Bay during water year 1997 (October 1, 1996–September 30, 1997). Optical backscatterance sensors and water samples were used to monitor suspended solids at two sites in Suisun Bay, three sites in Central San Francisco Bay, and three sites in South San Francisco Bay. Sensors were positioned at two depths at most sites. Water samples were collected periodically and were analyzed for concentrations of suspended solids. The results of the analyses were used to calibrate the electrical output of the optical backscatterance sensors. This report presents the data-collection methods used and summarizes the suspended-solids concentration data collected from October 1996 through September 1997 (water year 1997). Calibration plots and plots of edited data for each sensor also are presented.
