Stock-specific feeding grounds
Table 2. Correlation coefficients between δ13C values in salmon scales of several stocks and SST (averaged for Jan-Jun of the year of return). The time series were processed in different ways to disentangle the effect of low and high frequency variability on correlation estimates (original, detrended and smoothed). SST data for each stock were retrieved at the location marked in Figures 4, 5 and 6 by a white cross. P-values were calculated using the modified Chelton method to account for autocorrelation. P-values significance is: *** p<0.001, **p<0.01, *p<0.05.
