Five-year composite anomalies of cumulative summer chlorophyll-a concentration (Chl) (mg m⁻³) from 2000 to 2024. Panels show spatial anomalies relative to the long-term summer mean (2000–2024), averaged over consecutive five-year periods. Red shading indicates above-average productivity, while blue shading indicates below-average productivity. The inner sector represents high-latitude foraging grounds, while the outer sector represents mid-latitude foraging grounds.
