Cruise measurements (temperature, salinity, density, chlorophyll, C14, phosphate, silicate, nitrate, nitrite) collected from CTD casts aboard CalCOFI cruises in the California Current, and averaged annually and by cruise, from 1984 - 2019 (updated periodically).

Water column bottle sample data averaged across up to 46 standard stations (inshore and offshore) per cruise and then averaged over a varying number of cruises in any one year to give an annual average.
