Ongoing CalCOFI Cruises
The California Cooperative Oceanic Fisheries Investigations (CalCOFI) was originally formed in 1949 to study the ecological aspects of the sardine population collapse off California.
Today, CalCOFI.s 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. Quarterly cruises are conducted off southern & central California, collecting a suite of hydrographic and biological data on station and underway.
In 2004, CalCOFI added 9 SCCOOS stations to the standard 66 station pattern. Stations are typically positioned on the 20m isobath. On each station, a CTD Rosette is deployed measuring temperature, salinity, oxygen, fluorescence, transmittance, nitrate and PAR. Bottles analyze seawater for salinity, dissolved oxygen, chlorophyll-a, and nutrients. A Bongo net is also towed at every SCCOOS station. Marine mammal and sea bird visual surveys are conducted during transits between stations as well as marine mammal acoustics recording.
