This USGS data release archives and makes available all measurements from 1969-2015. Water-quality constituent measurements include salinity, temperature, light attenuation coefficient, and concentrations of chlorophyll-a, dissolved oxygen, suspended particulate matter, and dissolved inorganic nutrients (nitrate, nitrite, ammonium, phosphate and silicate). Since the mid-1990s, sampling was conducted at least monthly at 37 fixed sampling locations along a 145-km transect from lower South San Francisco Bay to the lower Sacramento River. A map and table of sampling locations are included in the Attached...
