Short summary
The upper layer of the Reloncaví fjord, Chile, shows a continuous stratification year-round. Nevertheless, the vertical salt flux seems to be balanced by the horizontal salt flux, which maintains the amount of salt into the fjord nearly as a steady state. The upper layer shows a flushing time of about 3 days.
