Water and sediment measurements in San Francisco Bay, California

Water samples collected in San Francisco Bay, the Gulf of the Farallones, and the delta of the Sacramento and San Joaquin rivers were analyzed for salinity, temperature, partial pressure of carbon dioxide (pCO²), chlorophyll a, alkalinity, particulate organic carbon (POC), and the stable carbon isotope ratio (δ¹³C) of the POC and total CO₂. Water sampling occurred between January 1976 and March 1977. Bottom sediments for total organic carbon isotopic analyses (δ¹³C(TOC)) were collected during August 1973. Numerical values are tabulated, sampling locations are identified, and the analytical methods are briefly described.
