About CalCOFI
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 incruise 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 We ask that these preliminary data not be published or redistributed.
The California Cooperative Oceanic Fisheries Investigations (CalCOFI) are a unique partnership of the California Department of Fish & Wildlife, NOAA Fisheries Service and Scripps Institution of Oceanography. The organization was formed in 1949 to study the ecological aspects of the sardine population collapse off California. Today our focus has shifted to the study of the marine environment off the coast of California, the management of its living resources, and monitoring the indicators of El Nino and climate change. CalCOFI conducts quarterly cruises off southern & central California, collecting a suite of hydrographic and biological data on station and underway. Data collected at depths down to 500 m include: temperature, salinity, oxygen, phosphate, silicate, nitrate and nitrite, chlorophyll, transmissometer, PAR, C14 primary productivity, phytoplankton biodiversity, zooplankton biomass, and zooplankton biodiversity.
