RESULTS 



The cross-correlation coefficients for upwelling 

 and crab catch are plotted in Figure 3 as a function 

 of lag time. The general shape of the function is 

 similar for the three different locations. The 

 coefficient for California at 0.5 yr lag is greater 



than for the other two. The value of the correlation 

 coefficient for California decreases while the value 

 increases for 1 yr at the other locations. This may 

 indicate that high correlation exists at a shorter 

 time lag in California than in ther other locations. 

 The auto-correlation coefficients for upwelling 

 are plotted in Figure 4. Significant correlation
