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 Data Reports Introduction. To see the methods used on specific cruises, refer to the cruise's Data Report pdf page. Preliminary data from recent cruises for which the data processing is not complete can generally be made available to those programs for which there is an operational need. Refer to the Contacts page for addressing such requests. We ask that these preliminary data not be published or redistributed.
CalCOFI research is supported by contributions from the participating agencies: The California State Department of Fish and Wildlife, NOAA,National Marine Fisheries Service, Southwest Fisheries Science Center, and the University of California, Integrative Oceanography Division at the Scripps Institution of Oceanography, UCSD.
