Figure 8. — Yearly estimates of the northern anchovy biomass (after Smith, 1972). The yearly total population estimates (upper left) 

 are grouped into 5-yr block averages (upper right). Also given are the central and southern subpopulation 5-yr block averages (lower). 



Table 8. — Rank-correlation coefficients' between the scale occurrences of the Pacific sardine, the northern anchovy, and the Pacific 



hake in sediment of Santa Barbara and Soledad Basins in = 32). 



'While the correlation coefficients above 0.35 appear significant, nevertheless due to autocorrelation inherent in these time series the probabilities 

 associated with these coefficients are likely to be greater than if the series were internally independent.
