a, c Climatological monthly mixed layer depth (m) calculated from temperature and salinity of World Ocean Atlas 2013 for the periods of January–June and for July–December, respectively. We simply calculated mixed layer depth as the depth at which a density increase from the sea surface value was > 0.125 σθ. Red solid circles represent observations in this study. b, d As in (a, c), except for along Leg 2 transect and expanded y-axis
