It is pointed out that physical and biological processes are usually coexistent and interact with each other during the sedimentation of suspended matters. This study used available figures showing the circulation pattern and surface sediment distribution in the whole China Seas, the Gulf of Maine, the Irish Sea and the North Sea, and additional data to verify that wherever upwelling exists on the continental shelf, mud must occur; and that wherever downwelling occurs, coarse sediment substitutes for mud.展开更多
