Research Progress in Area 2 方向 ( 二 ) 課題進展 141 Abstract The transport patterns of suspended particles in shelf seas are investigated by employing a hydrodynamic model and a particle-tracking technique. Trajectories of thousands of numerical particles transported by the simulated oceanic flows resemble marine sediment behavior. The role of physical oceanographic properties, such as ocean current direction/speed and bottom topography, in shaping the particle transport patterns are revealed. These model results will be utilized to improve the regional biogeochemicalphysical ocean model of the South China Sea for future environmental monitoring. Research Activities and Progress • Developed a set of tools for tracking the material transport in the ocean; • Investigate seasonal circulation patterns in shelf seas; • Extract transport patterns of suspended particles in shelf seas Key Findings • Material transport in shelf seas varies strongly with season; • Material transport in shelf seas is controlled by both turbulence and mean flow; • Particle tracking techniques can be utilized to reveal the connectivity between distinct oceanic regions.
