Since 1949, hydrographic and biological data of the California Current System have been collected on CalCOFI cruises. The 70+ year hydrographic time-series includes temperature, salinity, oxygen and phosphate observations. In 1961, nutrient analysis expanded to include silicate, nitrate and nitrite; in 1973, chlorophyll was added; in 1984, C14 primary productivity incubations were added; and in 1993, CTD profiling began.

Data Usage and Distribution Policy
CalCOFI hydrographic and plankton data are distributed to the community for use without restriction. Unless otherwise noted, these data can be considered final data which have been evaluated using CalCOFI data quality control procedures. Methods for data collection and processing are summarized in CalCOFI Data Reports introduction. To see the introduction or methods used on specific cruises, refer to the Data Report PDF page. Preliminary data from recent cruises for which the data processing is not complete are often made available. We ask that these preliminary data not be published or redistributed.
