Suspended-sediment concentration data were collected
by the U.S. Geological Survey in San Francisco Bay during water year 2004 (October
1, 2003–September 30, 2004). Optical sensors and water samples were used
to monitor suspended-sediment concentration at two sites in Suisun Bay, three
sites in San Pablo Bay, two 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 analyzed for concentrations of
suspended sediment. The results of the analyses were used to calibrate the
output of the optical sensors so that a record of suspended-sediment concentrations
could be derived. This report presents the data-collection methods used and
summarizes, in graphs, the suspended-sediment concentration data collected
from October 2003 through September 2004. Calibration curves and plots of the
processed data for each sensor also are presented.
