Northern Yellow Sea

Stable carbon and nitrogen compositions (δ13C, δ15N) of sedimentary organic matter were determined in the tidal flat of northern Yellow sea. The results showed that stable carbon and nitrogen isotopes compositions of the sediment samples ranged from −24.669～−19.457‰ and 2.125～7.043‰, respectively. The highest value was in St.DLD, and the lowest was in St.Z. Similar δ13C values were observed in St.H (−21.996±0.651‰) and St.P (−22.021±0.187‰), and similar δ15N values were between St.DLJ (5.502±0.223‰) and St.P (5.310±0.294‰). The δ13C and δ15N values did not show any significant regularity. The δ13C and δ15N signatures showed some fluctuation, no obvious regularity. The major source of terrestrial organic matter was from the emissions of river and human pollutant.
