Fig. 10: Boreal summer chlorophyll a distribution for exemplary years.

July–September (JAS) chlorophyll a distribution during a 2002, b 2003, c 2007, and d 2011. Magenta contours show the seasonal prevalence of near inertial wave events (as in Fig. 8c), but for the respective years; white contours show the corresponding mixed layer depth from the MIMOC climatology as in Fig. 8c (the latter without interannual variations). The cyan star marks the position of the PIRATA buoy at 11.5°N, 23°W.
