CalCOFI's sampling area has evolved over the 65 years of the program. The 66 standard station pattern in the Southern California Bight (SCB) has the best coverage since 1949. The current 75 station pattern, 66 standard + 9 SCCOOS 20m stations, was implemented in 2004. Refer to the Station Positions web page for coordinates for individual CalCOFI stations. Using perimeter station positions and several coastal station reference positions, here is the estimated sampling surface area using Google Maps Area Calculator:
