The grid lines and most stations are 40 miles apart with the latter numbered in multiples of ten. In referring to a station number under the present plan, the line number is given, then a decimal point, then the station number. The scheme facilitates quick identification : station 90.60 is station 60.0 on line 90.0, for example.
Below is a line and station table with desired position (decimal degrees) with average estimated bottom depth, and noted if it is a non standard station. The stations are listed by order occupied as working from South to North. Click this KML Google maps link for station positions & descriptions on a Google map (or download KML).
CalCOFI's standard station pattern since 1985 includes 66 stations from San Diego to Pt Conception (Lines 93.3 to 76.7). Nine additional coastal ~20m SCCOOS stations were added July 2004. Thirty-eight additional stations off central and northern California are typically scheduled during winter and spring cruises, time and weather-permitting (Lines 73.3 to 60.0). A 
The basic station plan used today for CalCOFI was originally conceived in 1950 and was a departure from a previous 1949 station plan. Both station plan maps are available below.
During winter and spring, 113 stations are normally occupied, weather-permitting. The 38 additional stations located north of Point Conception (lines 73.3 through 60.0) are surveyed but the ship may only stop when fish egg densities are high. Line 66.7, off Monterey, is part of the
