USGS Measurements of Water Quality in San Francisco Bay (CA), 1969-2015
The U.S. Geological Survey maintains a program of water-quality studies in San Francisco Bay (CA) that began in 1969. We plan a USGS Data Release to archive and make available all measurements made from 1969 through 2015. Water-quality constituents include salinity, temperature, light attenuation coefficient, and concentrations of chlorophyll-a, dissolved oxygen, suspended particulate matter, nitrate, nitrite, ammonium, silicate and phosphate. Water samples are collected at 37 fixed sampling locations along a 145-km transect from lower South San Francisco Bayo the lower Sacramento River. A map of sampling locations is available on the project website at: https://sfbay.wr.usgs.gov/access/wqdata/overview/wherewhen/stnmap.html
