Data Archives - Mar 1949 - Feb 2006

Since 1949, hydrographic and biological data of the California Current System have been collected on CalCOFI cruises.  The 54+ 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.
These data are available on the CalCOFI website as:

• Downloadable IEH ascii files (1949-2006). two versions: (YY=year, MM=month)
  
  IEH Format Description - CalCOFI data archive column-specific description.

Ancillary data collected include bio-optics, air-sea interface, and atmospheric measurements (for satellite calibration); continuous underway sea surface measurements (temperature, salinity, fluorescence); Acoustic Dopler Current Profiler (ADCP) data; trace metals; sediments; MOCNESS net sampling; and the Continuous Underway Fish Egg Sampler (CUFES).
