Abstract

Core sediments in the Bohai have been analyzed to assess the sources and diagenesis of organic matter. Two sampling sites have been chosen: E3 and E5, which are located in the center of Bohai Bay. It is indicated that the most important organic source is the terrestrial matter transported by the Yellow River into the Bohai by analyzing the distribution of n-alkanes. The variation of H/L ration along the core could reflect the change of the Yellow River in the history. The observation of the reduced CPI value may suggest the dryness and dams over the Yellow River in these days. With the ratio of BrC_15:0/nC_15:0 and nC_18:1/nC_18:0 of fatty acids, it is elucidated that fatty acids could be easily degraded in the anoxic than the oxide environment.
