  • fig. S8. Spatial distribution of CHL and NO3 anomaly localized within the
    perimeter of ACEs during winter based on the third principal component of their
    REOF decomposition (see Fig. 2).
  • table S1. Mean relative difference between surface CHL in ACEs and surface
    CHL in CEs in the subtropical gyres during winter.
  • table S2. Spatial statistical parameters of the relative difference between surface
