The U.S. Geological Survey conducted hydrologic investigations in San Francisco Bay between October 1991 and November 1993. Dissolved inorganic plant nutrients, nitrate, nitrite, ammonium, silica, and reactive phosphorus were measured in surface and in near-bottom waters at previously established locations in both northern and southern reaches of the bay. Salinity, turbidigy, and concentrations of suspended particulate matter also were measured. Additionally, concentratons of dissolved organic nitrogen and phosphorus were occasionally measured. This report presents the sampling and analytical methods, and the data for these studies. Data on the variability due to sampling and sample handling procedures, on the precision of the analytical methods, and on recoveries of known additions from samples are also presented.
