Herein, we report field studies of the seasonal and daily dynamics of the mixing zone in the micro-tidal mouth of the Partizanskaya river. The position of the mixing zone was determined according to the volume of river run-off. The upper boundary of the mixing zone was observed at 5 (at a river run-off of 73.67 m3/s) to 12.5 km (at 7.7 m3/s) from the mouth bar. The estuary is characterized by a two-layer circulation of water, which results in a halocline with a salinity gradient of up to 30% per 1 m. Variations of salinity in the rifts caused by tides reaches 27% over 3 h.
