DIC: Dissolved Inorganic Carbon
CalCOFI collects samples for inorganic carbon and total alkalinity at specific stations throughout the cruise track. Seawater samples are collected from several depths, preserved and brought back to SIO for total inorganic carbon and total alkalinity analysis. These measurements allow the calculation of pH and pCO2. The objectives of these measurements are: first, the long-term…

Available Data
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…

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 each cruise’s Data Report Introduction. To see the methods used on specific cruises,…
