Suspended matter samples obtained from the Taiwan Shoal and on its adjacent shelves from July 25 to August 10, 2004 were studied using scanning electron microscope (SEM) and energy disperse spectroscopy (EDX). The types of settling particulate matter (SPM) and their flocculating sedimentation are discussed. It is shown that the types of single particle are biology and mineral, among others, and that the types of flocs of SPM include larvacean houses, fecal flocs, diatom flocs, mineral flocs, organic film, miscellaneous flocs, minitype algae flocs, etc. The types of SPM are affected by ocean environment, such as topography, currents and land-based sources of input. Bio-flocculation and upwelling may be the primary reasons of aggregated SPM. Flocculation plays a very important role in the sedimentary processes of suspended matter.
