Physical and chemical properties of San Francisco Bay waters, 1969-1976

Basic data on the physical and chemical properties of San Francisco Bay are presented here. Samples were collected over the period 1969-1976 at approximately six-week intervals at 36 stations. The stations were located along the axis of the Bay from Calaveras Point in South San Francisco Bay to the town of Rio Vista on the Sacramento River. On most cruises vertical profiles of the water properties were taken at 12 of the 36 stations. The samples were analyzed for the following core parameters: salinity, temperature, light transmission, chlorophyll a fluorescence, dissolved oxygen, orthophosphate, nitrate+nitrite, nitrite, ammonia, and silicate. Other analyses performed on selected samples included: particulate organic carbon, alkalinity, pH, pCO₂, and suspended particulate weight. The results of these analyses and the analytical methods used are documented in this report.
