 The California Cooperative Oceanic Fisheries Investigations (CalCOFI) are a unique partnership of the California Department of Fish and Game, 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.

Interested in participating in an oceanographic cruise? CalCOFI cruises are staffed by personnel from the following agencies: National Marine Fisheries Service (NOAA), Integrative Oceanography Division at Scripps Institution of Oceanography, and California Department of Fish & Game. Volunteers are recruited to help deploy equipment, collect data, and draw and analyze seawater samples. General criteria:
- sea-worthiness (experience at sea, recreational is acceptable)
- good health
- scientific background
- ability to follow detailed instructions carefully
- ability to work safely on an oceanographic cruise
- availability - most cruises are 18 - 20 days; some winter & spring cruises are longer
- ability to work a 12hr watch (noon to midnight or midnight to noon) for +18 days
Additional information is available in the CalCOFI Handbook. If you are interested in participating, please send a resume and a brief description of your seagoing experience and interests to

Since 1949, hydrographic and biological data of the California Current System have been collected on CalCOFI cruises. The 61 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 1993, CTD profiling began.
