摘要
A large-scale hydrological and sedimentological investigation was carried out off the Yellow River mouth and the nearby Bohai Sea during August-September 2007. Approximately 227 suspended sediments and 245 surface sediments samples were selected to determine organic carbon and nitrogen contents using an elemental analysis instrument. The data show that the TOC content in surface sediment is lower than POC content in bottom suspended sediments and especially lower than that in surface suspended sediments in the same sampling stations. The study area can be classified into five provinces based on TOC, TN and POC data. The results demonstrate that the contents of POC, TOC, TN and their distribution are mainly controlled by sources and sedimentary dynamic environment.
