Figure 6. Estimated feeding grounds during the last summer at sea of (a) Ozernaya and (b) Kamchatka sockeye salmon stocks (Russia). Strongest correlation coefficient between SST and δ13C value is indicated by a white cross. Locations of the point of entry in the freshwater system of the different stocks is shown (red circle).
The first mode of the EOF analysis applied to SST data for 1968-1998 explained 43% of the total variance and showed that waters from SW Alaska and North BC coast covaried (Figure 7).
