Impact of Typhoon Morakot on suspended matter size distributions on the East China Sea inner shelf

Our analyzes suggest that the dynamic process of the typhoon caused the seafloor sediment resuspension, which significantly increased the suspended matter volume concentration in addition to the increase of terrigenous materials due to high-intensity rainfall accompanying the typhoon. The typhoon process also decreased the suspended matter size and macrofloc (>133 μm) concentration by strong disturbance of water column and the temporary demise of plankton under heavy cloudy condition.
