Abstract：In Dec. 2008, a total of 137 samples were collected from 34 stations off the northern Huanghe Delta to analyze the suspended sediment concentration (SSC) and particulate organic carbon (POC). The results show that the SSC varied between 5~1064mg/L, both the surface and bottom high SSC zone (>600mg/L) located parallel to the coastline along the delta coast of the abandoned Diaokou-Shenxiangou river mouth. The SSC decreased dramatically seaward with increasing water depth. The POC ranged from 17 to 640mg/L, with similar distribution pattern in surface and bottom layers. The high POC zone also located along the delta coast, however, this zone extended even further in the bottom layer, from the Diaokou mouth area to the central Bohai Bay. A significant positive correlation existed between POC and SSC, suggesting that the source of suspended sediments was an important factor for the POC. In winter, the high zones of SSC and POC were correlated well with the erosion center and the high wave-induced bottom shear stress (>0.2N/m2) off the abandoned Diaokou river mouth. This study suggests that the delta coast areas off the abandoned Diaokou-Shenxiangou river mouth were not only the major source of SSC, but also the POC, most likely caused by the strongly winter storm waves.
