Interannual variability of CHL and physical parameters averaged within the 160–200°E and 16–25°N region (see the black box in Fig. 1 for the region) obtained in June and July. (a) Mean CHL concentration. (b) Mean area with CHL concentration >0.1 mg/m3. (c) CTD-obtained buoyancy frequency averaged over 200 m from the JPBN and JGQH cruises along the 165°E transect. (d) Total eddy number. (e) Mean geostrophic-current speed of eddies. (f) Mean eddy area. Red dots and blue squares in (c) represent the CTD observation executed in June and July, respectively (the time series without points show no available CTD observation in June or July). Blue and red curves in the right panels are for cyclonic and anticyclonic eddies, respectively. All dashed curves show the plus-minus standard deviations of the mean analysis for the relative parameters.
