  abstract = {{A} thin layer of fresh water from summer monsoon rain and river runoff in the {B}ay of {B}engal ({B}o{B}) has profound influence on air-sea interaction across the south {A}sian region, but the mechanisms that sustain the low-salinity layer are as yet unknown. {U}sing the first long time series of high-frequency observations from a mooring in the north {B}o{B} and satellite salinity data, we show that fresh water from major rivers is transported by large-scale flow and eddies, and shallow salinity stratification persists from summer through the following winter. {T}he moored observations show frequent 0.2-1.2 psu salinity jumps with time scales of 10 min to days, due to {O}(1-10) km submesoscale salinity fronts moving past the mooring. {I}n winter, satellite sea surface temperature shows 10km wide filaments of cool water, in line with moored data. {R}apid salinity and temperature changes at the mooring are highly coherent, suggesting slumping of salinity-dominated fronts. {B}ased on these observations, we propose that submesoscale fronts may be one of the important drivers for the persistent fresh layer in the north {B}o{B}.},
