Fig. 2

Time-depth sections of a the density, b the potential temperature, c the salinity, d the fluorescence (relative units), e dissolved oxygen (umol/kg), and f the horizontal current velocity along the A-A′ line in Fig. 1. The dashed and dotted lines indicate the MLD and ILD, respectively. The blue line indicates the 29, 25, and 20 °C isotherms. The surface wind speed is superimposed in f with the right axis. The 2-hour running mean is adopted for each variable. The periods of the open Indian Ocean, oceanic ridge, and marginal sea defined by the bathymetry in Fig. 1 are indicated at the bottom in each panel. The bars at the top of each panel show the vertical gradients of the density, temperature, and salinity between 6 and 10 m (green: values more than 0.01 kg/m4, 0.03 °C/m, and 0.013 1/m, purple: less than 0.01 kg/m4, 0.03 °C/m, and 0.013 1/m)
