Abstract

Intensive field measurements of water quality and current were carried out in summer 2010 off the Toyogawa river mouth located at the head of Mikawa Bay. Structures of water density and dissolved oxygen concentration and their variations were discussed based on the data. The residual currents were compared with wind data and freshwater discharge from the river. The estuarine circulation observed in the measurement seemed to be caused mainly by wind action, but large amount of freshwater discharge may cause current toward the river mouth near the bottom. Dissolved nutrients especially phosphorus may be transported upstream by the bottom flow and used in the primary production in shallow waters.
