海洋中悬浮颗粒物质(SPM)的化学特征和沉积通量的研究对于了解全球物质循环和确定海洋吸收、贮存和转移碳能力的生物地球化学过程具有重要的意义。陆架海洋沉积物的再悬浮作为海洋悬浮颗粒物质的一个重要来源已引起本领域专家的重视(詹滨秋等,1993)。Hosika等(1994)在研究东海陆架和沿岸区时,证实在东海存在一个底层涡动层, The study of the chemical characteristics and sediment fluxes of suspended particulate matter (SPM) in the oceans is of great importance for understanding the global material circulation and biogeochemical processes that determine the ability of the oceans to absorb, store and transfer carbon. The resuspension of continental shelf sediments as an important source of marine suspended particulate matter has drawn the attention of experts in the field (Zhan Bijiu et al., 1993). Hosika et al. (1994), in the study of the East China Sea shelf and coastal areas, confirmed the presence of an underlying turbulent layer in the East China Sea,
