However, between 1000 and 1400 IST, when the ML salinity shows an increasing trend, the horizontal advection estimated from uCTD and SMAP SSS shows near-zero value in contrast to a mild positive tendency as apparent in TSG-based estimate (Fig.

The sentences
Vertical salinity profiles show a decreasing trend with depth, suggesting that the vertical processes can freshen the ML (~ − 0.03 psu day −1 ) through the entrainment of relatively low saline sub-surface water to the ML during the deepening phase of ML during the night (Figs. 4 b and 9 a).
