| Abstract: | Transport mechanism of suspended matter above the shelf slope is investigated with the use of the moorings of time-series sediment trap, current meter and nephelometer at three stations at the mouth of Tokyo Bay, Japan during 21 to 25 August 1993. Tidal pump mechanism is effective for the transport of suspended matter at the shelf edge, but the boring-like flood tidal current resuspends the settled suspended matter, on the bottom of shelf slope and the resuspended matter is resulted to be moved upslope in one tidal cycle at 10 m above the bottom of shelf slope. |
