| Abstract;The movement of the water mass off Kannon-zaki is influenced significantly by tidal variations. During the flood tide, seawater with a low temperature, high salinity, and low turbidity flows to the north especially through the bottom layer. During the ebb tide, seawater with a high temperature, low salinity and high turbidity flows to the south through both the surface layer and the bottom layer. On the other hand, the movement of the water mass off Futtsu-misaki corresponds to the tidal current. During the flood tide, high turbidity seawater flows to the northwest through the bottom layer. During the ebb tide, seawater with high temperature and high turbidity in the surface layer, and seawater with low temperature, high salinity, and low turbidity in the bottom layer flows to the southeast. The outflow and inflow of suspended solids during the one day were as follows. Off Kannon-zaki in June, there were outflows of 7.3 kg/m2/day through the upper layer, and inflows of 11.3 kg/m2/day through the lower layer. On the other hand, off Futtsu-misaki in September, there were outflows of 7.2 kg/m2/day through the upper layer, and inflows of 4.9 kg/m2/day through the lower layer. At the mouth of Tokyo Bay, the exchange rate of suspended solids in the upper layer was higher than that in the lower layer. Notably, the difference was much larger on the Kannon-zaki side. Thus it is considered that turbid seawater at the mouth of Tokyo Bay flows out through the upper layer, part of it reaches the open sea, and the rest returns through the lower layer to the inner bay area.
