ABSTRACT
From April 2010 to December 2011, East China Sea Forecast Center led and cooperated with East China Normal University and Shanghai Estuary and Coasts Scientific Research Center which are implementing agencies of the offshore projects as well as East China Sea Centre of Standard Metrology, SOA which is the unit to cooperate with the field operation to carry out the monitoring of sediment concentration and marine current at fixed-points and sections and two fixed points of subsurface buoy under extreme weather conditions at the time of spring tide and neap tide during four voyages in the wet season and dry season of 2010 and 2011 and obtained the data of sediment concentration and marine current at section of Yangshan Port area. The current field and sediment characteristics at Yangshan Port are then analyzed with the data. The elements surveyed were the current velocity, current direction, water depth and sediment concentration. The data of subsurface buoy survey includes the data of ADCP monitoring of marine current and data of OBS monitoring of sediment concentration during two strong wind processes.
