Figure 8

Temperature-salinity (TS) diagram with density sigma-t (contours) based on Argo floats in the region of interest in June and July. Red dots are for measurements with CHL concentration larger than 0.1 mg/m3 at the surface in 2010. Blues dots are for those with CHL concentration smaller than 0.05 mg/m3 at the surface in 2010. Green dots are for those climatological TS corresponding to red dots. Horizontal and vertical error bars in gray show the standard deviation for the climatological salinity and temperature, respectively.
