Since 1949, hydrographic and biological data of the California Current System have been collected on CalCOFI cruises. The 66+ 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.

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 final data which have been evaluated using CalCOFI data quality control procedures. Methods for data collection and processing are summarized in CalCOFI Data Reports introduction. To see the introduction or methods used on specific cruises, refer to the Data Report PDF page. Preliminary data from recent cruises for which the data processing is not complete are often made available. We ask that these preliminary data not be published or redistributed.
I. Reports and Reviews
II. Scientific Contributions
The graphic below is a reproduction from an article in which researchers at SIO are corroborating these predictions with observations.
El Niño is an abnormal warming phase in the Pacific Ocean Sea Surface Temperature (SST), while the abnormal cooling is known as La Niña - these shifts are part of the El Niño Southern Oscillation or ENSO. The current ENSO phase is often quantized by a deviation from normally observed SST using the Oceanic Niño Index or ONI. While El Niño and its counterpart cooling phase La Niña are still being researched, the seasonal effects are becoming well understood with long term data sets.
Using the table below from NOAA's Climate Prediction Center in conjunction with the CalCOFI database - can offer information on how the environment has reacted in response to the different phases and intensities of the ENSO.
