Overview
In order to reveal mixing processes in river plumes in Otsuchi Bay, we will observe river flows, tidal flows, temperature and salinity in the Unosumai River. We will deploy mooring systems and carry out a tow-yo CTD survey in the river to observe temperature, salinity, flows. In addition to the mooring surveys, we will use a towing ADCP for estimating the river flow in the rivers.
