Distribution of dissolved and particulate organic carbon in the East China Sea in summer

摘要: This study was conducted around the southwest sea areas of Jeju and coastal China in August 2003 September 2004 to research distribution patterns dissolved inorganic nutrients, particulate organic carbon. Distribution nutrients East Sea summer were shown be influenced by water masses phytoplankton. Water summer, except for china, showed less vertical mixing process, causing decline inflow surface water. Bottom water, however, high concentration, since made matters from accumulated at bottom. with concentration chlorophyll a low vice versa, indicating biological activities control nutrients. The carbon didn't show any correlation salinity, temperatures, masses. Areas river mouth Changjiang more than , but relatively Jeju, that has great influence on Sea. highest average By comparison, southeast which Taiwan warm current influence, central Jeju. Thus, there is much indication serves as supplier along autogenous source. In general, if Chlorophyll a, it thought originated However, shows salinity below 30, therefore proper think its origin terrestrial source rather autogenesis.
