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 to be final data which have been evaluated using CalCOFI data quality control procedures. Methods for data collection and processing are summarized in cruise data reports introduction. To see the methods used on specific cruises, see the 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 We ask that these preliminary data not be published or redistributed.
