Abstract

The mechanism of material transport from Tokyo Bay to the Pacific Ocean is discussed. The average mass flux from Tokyo Bay to the Pacific Ocean can be evaluated by subtracting the burial flux from the influx through rivers. This method, however, does not give further insight into the mechanism of mass transport. Temporal and spatial variations in the current and material concentration within Tokyo Bay must be taken into account in order to clarify the mechanism of mass transport. Tidal fluctuations dominate the currents in Tokyo Bay but the mass transport is mainly governed by the residual flow except particular places such as near the straits or around shelf edges. We first evaluate the residual flow by a diagnostic model and estimate the mass transport using data on the distribution of material concentration and on current. The transport of sinking particles, however, cannot be evaluated by the above mothod. We then conducted a sediment trap experiment at the mouth of Tokyo Bay.
